    Structure o the manual

    2 Street design elements

    discusses sixteen elements that

    make up a street: ootpaths, the

    carriageway, cycle tracks, service

    lanes, bus lanes, landscaping,utilities, and so on. For each element,

    we present design principles that

    govern the element in relation

    to others, provide photos o good

    and bad practices, and illustrate

    design options under varying

    circumstances.

    3 Street templates

    is a collection o street templates

    or typical road widths. For each

    width, we present a range o

    design solutions. The templates are

    based on the standards laid out in

    Chapter 2.

    4 Intersection templates

    shows how the standard templates

    presented in Chapter 3 come

    together at intersections.

    5 Design process

    explains our street design process,

    rom the development o a vision

    through the completion o a fnal

    design, using the example o an

    urban intersection.

    1 Introduction

    lays out our vision or better street

    design. It explains why streets need

    to be designed or all users, not just

    or motor vehicles.

    Streets rank amongst the most valuable assets

    in any city. They not only ensure residents

    mobility, allowing them to travel rom one place

    to another, but also are a place or people to meet,

    interact, do business, and have un. Streets make

    a city liveable. They oster social and economic

    bonds, bringing people together. Decisions about

    how to allocate and design street space have atremendous impact on quality o lie.

    Indian cities struggle to reconcile the competing

    needs o mobility and liveability. As private

    motor vehicle ownership grows and governments

    attempt to accommodate the additional vehicles,

    it is becoming more and more difcult to retain

    adequate space or the social and economic

    activities that traditionally have taken place

    in our streets. Over time, streets have come to

    unction less as social gathering spaces and

    market areas, and more as conduits or an ever-increasing quantity o trafc.

    One o the key problems o Indian streets is that they

    are designed rom the centreline outwards, without

    taking the needs o all users into account. The

    median is marked and a carriageway constructed,

    and the undefned outer area is let or other

    purposes. Ater parking eats away a signifcant

    share o this area, pedestrians, trees, utilities, street

    vending, and social activities jostle or whatever

    space remains. It is no wonder that in most cases

    the letover space is not sufcient to saely and

    comortably accommodate these essential unctions

    o the street.

    Designs ocus on improving private motor vehicle

    mobility by allocating more space to itoten at the

    expense o other unctions o the street. However,

    the reality that they create is dierent: pedestrian

    ootpaths may vanish but the pedestrians do not,

    and the lack o proper pedestrian inrastructure

    orces people to walk on the carriageway itsel. The

    same is true or cyclists, street vendors, and public

    transport. Eventually, everyone ends up sharing

    what is constructed as a motor vehicle carriageway,

    leading to a reduction in the amount o space that

    is usable by vehicles. The resulting arrangementis inconvenient, uncomortable, and unsae or

    everyone, including motor vehicle users. So, why

    not provide adequate space or all users in the frst

    place?

    All streets that aim to maximize mobility also

    need separate slow zones. The slow space is or

    liveabilityor people to walk, talk, and interact, or

    doing business, or children to play. The provision

    o an adequate slow zone makes it possible or

    the mobility zone o a street to provide or sae,

    relatively uninterrupted mobility at moderate

    speeds. The result is a saer and more pleasant street

    environment or everyone.

    It should be noted that the motor vehicle capacity

    o urban streets is determined primarily by how

    quickly vehicles can clear intersections. Though

    constructing wide carriageways may allow or aster

    mid-block speeds, it does not enhance throughput,

    or intersections are the true bottlenecks. Widening

    the carriageway at the intersection, through the

    addition o queuing space, is a more eective way o

    increasing throughput.

    Figure 1.1 I a street does not provide separate space or

    pedestrians, people will walk in the carriageway.

    Figure 1.2 A street with adequate space or walking and

    other activities is saer or pedestrians and allows or

    smoother motor vehicle movement.

    Streets need room or all users

    The frst question that oten emerges when one

    talks about accommodating pedestrians, cyclists,

    and street vendors is, Will that not reduce trafc

    movement? Yet vehicle movement and mobility

    are not one and the same. Mobility is about

    getting people to where they want to go, efciently,

    conveniently, and saely. Mobility can be provided

    through high quality, high capacity public transport,which does not necessarily mean moving large

    numbers o vehicles.

    Even i a road widening or yover reduces congestion,

    the improvement is usually short-lived. The reason is

    simple: expanding the available road space initially

    increases speed and comort and thereby encourages

    more people to travel in private motor vehicles. More

    and more users take to the route until the wider road

    returns to its original level o congestionbut with

    signifcantly more vehicles stuck in trafc.

    A city government in turn may eel pressure to

    widen the road once again, but it is not possible to

    solve trafc jams by building larger and larger roads

    indefnitely. In act, no city in the world has solved its

    mobility crisis by simply building more roads. On the

    contrary, some o the cities with the most elaborate

    road networks also have the worst congestion.

    The only viable long-term solution or ensuring

    mobility is to build high quality acilities or public

    transport and non-motorised transport. These modes

    can carry large numbers o passengers without an

    exponential increase in road space requirements. For

    most Indian cities, the most viable option is bus rapid

    transit (BRT). A single BRT lane with articulated buses

    can carry 10,000 passengers per hour per direction.

    The same lane can carry little over 1,000 cars per

    hour1,200 to 1,500 persons at typical occupancy

    ratesassuming that the lane receives one hal o

    the signal time at intersections.

    There are solutions to trafc congestion too. The

    key to reducing congestion is lowering the number

    o vehicles on streets rather than increasing street

    widths to accommodate an ever-growing number o

    vehicles. This can be done through various means,including parking ees, congestion charges, and other

    travel demand management tools as well as through

    trafc calming. At a larger scale, compact, walkable

    urban design is the key to reducing congestion by

    keeping trip lengths short.Figure 1.4 A dedicated bus lane can carry many times asmany passengers as a mixed trac lane.

    Making streets more efcient,not simply widening them, cansolve our mobility problems

    Figure 1.3 Wider roads, expressways, and fyovers bring

    temporary relie, but in the long run they only exacerbate a

    citys trac problems.

    What makes up a complete street?

    slower aster slower

    Shared zone Mobility zone Shared zone

    slow

    Shared zone

    A complete street that caters to all users can takeon a variety o orms, depending on actors such as

    the available right-o-way, trafc volumes, street-side

    activities, and adjacent land uses.

    In general, smaller right-o-ways can unction as

    slow shared spaces used by both pedestrians and

    Figure 1.5 The 7.5 m street (let) is designed as a shared space. The 42 m street (right) includes a slow-speed shared lane

    similar to the 7.5 m section, but it also provides separate spaces or mobility, including a cycle track, carriageway, and bus

    rapid transit lanes.

    Shared lane

    vehicles. Street vending and social activities can alsotake place in the shared space. A narrow driving lane

    and other trafc calming elements help keep vehicle

    speeds low, so that vehicle movement remains

    compatible with the other uses.

    A larger street can cater to walking and stationary

    activities as well as through movement, but it otenmakes sense to dierentiate the slow, shared zone

    rom the mobility zone to ensure comort and saety

    or pedestrians and stationary users. The cycle track,

    though part o the mobility zone, is also segregated

    rom motor vehicle trafc.

    Principles or street design

    Saety

    Streets must be sae or

    all users. This implies

    that every street needs to

    have a slow zone where

    pedestrians have priority.

    In smaller streets with a

    shared space ormat, the

    entire street becomes a

    slow zone or all users,

    including pedestrians,

    vendors, cycles, and cars.

    Mobility

    Larger roads can also

    include a mobility zone

    or vehicle movement.

    This mobility zoneor

    private vehicles and public

    transportis physically

    separated rom the slow

    zone. The mobility zone

    may include a physically

    segregated cycle track

    i the speed dierential

    between cyclists andmotor vehicles is high.

    In addition, dedicated

    bus lanes can improve

    service quality or public

    transport users.

    Pedestrian accessibility

    All streets need to have

    continuous ootpaths with

    minimal grade dierences

    and adequate clear width

    or pedestrian through

    movement.

    Liveability

    Elements such as tree

    lines, landscaping, and

    urniture enhance a

    streets slow zone, creating

    space or relaxation,

    interaction, vending, and

    other activities.

    Sensitivity to

    local contextStreet design should actor

    in local street activities,

    patterns o pedestrian

    movement, and nearby

    land uses.

    Creative use o

    street spaceFor example, the width

    occupied by a parking

    lane can become multi-

    unctional i it includes

    occasional bulb-outs or

    street vending or street

    urniture.

    The design approach outlined in this manual is guided by the ollowing principles:

    We defne sixteen street design elements as

    the street components that accommodate or

    serve specifc unctions. For example, a ootpath

    supports pedestrian movement, and street lights

    improve saety. The fgure on the let shows allsixteen elements.

    Street design elements demand detailed planning

    and need to be customized to ft the local context.

    Getting the elements in the right proportion and

    location is challenging because all elements

    interact with one another. For example, utility-

    oriented elements lie mainly underground, but

    when they surace on a pedestrian path (or

    instance, in the orm o a phone relay box), the

    obstruction may cause pedestrians to walk on the

    main carriageway.

    In this chapter, each street design element is

    briey discussed in our subsections:

    2.1 FootpathsWhat good ootpaths achieve

    Good ootpaths promote sae and comortable

    pedestrian mobility. Together with other elements,

    such as urniture and landscaping, they constitutethe primary public space o a city and are

    accessible to all users, regardless o age, gender, or

    special needs. Good ootpaths are inviting spaces

    where people can meet, talk, sit, and eat.

    Signifcance o ootpaths

    A signifcant proportion o trips, especially those

    below 2 km, are perormed on oot. For example,

    the share o pedestrian trips in Ahmedabad is

    38 percent.1 Additionally, all public transport

    passengers and many private vehicle users start

    and end their trips as pedestrians on publicstreets. Hence accommodating pedestrians is

    an essential, i not the most important, task o

    transportation planning.

    Footpaths are a critical elements o the

    streetscape unless trafc calming makes

    ootpaths unnecessary. In smaller streets and

    service lanes, speed dierentials may be small

    enough or pedestrians and motor vehicles to

    coexist in a pedestrian-priority space.

    Challenges to better ootpathsStreets oten are designed rom the centerline

    outward, with priority given to motorised vehicles.

    Whatever space is let over ater creating the

    carriageway and parking is designated as the

    ootpath. The placement o utility boxes, trees,

    1 Center or Environmental Planning and Technology,Comprehensive Mobility Plan and Bus Rapid TransitSystem Plan, Phase II (Ahmedabad: 2008) 4-5.

    and light poles on the ootpath leaves no clear

    space or pedestrian movement.

    Even with an adequate width, a ootpath may be

    difcult to use i it ends requently at propertyaccess points. High curb heights and steps make

    ootpaths difcult to use.

    Poorly designed ootpaths remain under-utilized

    and are easily encroached by parked vehicles

    and shops. In the absence o an adequately sized

    and usable ootpath, the only clear space let or

    pedestrians is the carriageway.

    Design criteria and standards

    Comort, continuity, and saety are the governing

    criteria or the design o pedestrian acilities.Footpaths should be provided on all streets,

    except on trafc calmed small streets

    Footpaths should incorporate the ollowing:

    A continuous unobstructed minimum width o

    2 m

    No breaks or obstructions at property

    entrances and side streets

    Continuous shade through tree cover

    No railings or barriers that prevent sideways

    movement on and o the ootpath

    Elevation over the carriageway (e.g. +150 mm)and adequate cross slope or storm water

    runo. At the same time, the elevation should

    be low enough or pedestrians to step onto and

    o o the ootpath easily

    Surmountable gratings over tree pits to

    increase the eective width o the ootpath

    Figure 2.1 This ootpath is wide, continuous, and

    shaded. However, the continuous encing towards the

    carriageway prevents ree pedestrian movement.

    Figure 2.2 This recently constructed ootpath does

    not accommodate obstacles in a way that would

    allow pedestrians to eectively use the ootpath.

    Figure 2.4 The smallest well unctioningootpath/tree package has a width o 3 m,

    including a 2 m clear space and 1 m tree pits.

    Street urniture is positioned in line with the

    tree pits to maintain 2 m o clear space.

    Wider ootpaths can accommodate street

    vending and larger seating areas and are

    recommended in areas with large pedestrian

    volumes.

    Figure 2.5 Where required to enable the

    access to private properties or to the ootpath

    itsel, vehicle ramps should be provided in

    the landscaping strip but not in the area o

    pedestrian through movement.

    Ending the ootpath with abrupt curbs or

    lowering the entire ootpath to the level o

    the carriageway is unacceptable as property

    entrances may become waterlogged.

    Figure 2.3 Footpaths have distinct zones that

    serve separate purposes:

    Pedestrian zone. This zone provides

    continuous space or walking and should

    be clear o any obstructions. It should be at

    least 2 m wide.

    Frontage zone. Provides a buer between

    street-side activities and the pedestrian

    zone. Next to a compound wall, the

    rontage zone can become a plantation

    strip.

    Furniture zone. This is a space or

    landscaping, urniture, lights, bus stops,

    signs, and private property access ramps.

    Cycle tracks

    Figure 2.7 This cycle track has our problems: (1)

    it is not continuous, (2) it collects water runo

    and dirt because it is at the lowest point in the

    cross section, (3) it is not properly separated rom

    the carriageway, and (4) the curbs and signpost

    reduce the usable width.

    Figure 2.6 This cycle track is continuous and shaded.

    Curb heights are apropriate, and storm water drains

    into catch pits located in the landscaped buer.

    What good cycle tracks achieve

    Good cycle tracks are continuous and provide or

    uninterrupted movement. They are physically

    separated rom the main carriageway to ensureboth comort and saety, and are protected rom

    encroachment by parked vehicles, pedestrians,

    and street vendors.

    Signifcance o cycle tracks

    The cycle is a core mode o urban transport.

    Cycles oer low-cost, pollution-ree mobility and

    occupy only a fth as much driving and parking

    space as automobiles.

    Due to the lack o physical separation o

    motorized and non-motorized vehicles, cyclists

    ace inconvenience and saety hazards rom

    aster moving trafc. Thereore, the provision o

    sae and convenient inrastructure is essential to

    attract new users. Where motor vehicle lanes are

    saturated, cycling in a segregated track is oten

    aster than using a private motor vehicle.

    Challenges to better cycle tracks

    There is signifcant resistance to creating

    dedicated cycling acilities, with the alling cycle

    mode share cited as an excuse. Even i mode

    shares are signifcant, cyclists are typicallyinvisible in the planning process. Where they do

    exist, cycle tracks are oten discontinuous and

    poorly constructed, leading to a sel-ulflling

    prophesy that cyclists do not use cycle tracks.

    A lack o enorcement aggravates the situation

    urther, as cycle tracks are easily taken over or

    activities such as parking and street vending or

    as a travel lane or motorised two-wheelers. Any

    cycle track that is easily accessible to cyclists is

    also accessible to motorised two-wheelers.

    Design criteria and standards

    Efcient cycle tracks are sae, convenient,

    continuous, and direct. On streets with high speed

    trafc, cycle tracks can reduce conicts between

    cycles and motor vehicles.

    Cycle tracks in the median reduce conicts

    with parking and street-side activities. However,

    street-side cycle tracks may be provided where

    encroachments due to parking or commercial

    activity are minimal, as may be the case i a

    service lane is available.

    Cycle tracks should incorporate the ollowing:

    A minimum width o 2 m or one-way

    movement and 3 m or two-way movement

    Continuity to allow or reasonable speeds

    A smooth surace materialasphalt or

    concrete. Paver blocks are to be avoided

    Bus rapid transit2.4What good BRT achieves

    Bus rapid transit (BRT) can oer high-capacity

    and high-quality public transportsimilar to a

    metro rail but at a lower costby providing an

    exclusive right-o-way or BRT buses.

    Signifcance o BRT

    Urban growth and rising car ownership are

    causing severe road congestion. Longer travel

    times make existing bus transport less attractive,

    reducing public transport patronage and

    increasing private vehicle use. BRT can break this

    vicious cycle by maintaining competitive travel

    times and reliable scheduling in road-based public

    transport. BRT is the only fnancially viable option

    or providing high quality public transport serviceto a majority o urban residents in a short time

    span. BRT with median bus lanes also improves

    saety or cyclists by eliminating conict points at

    bus stops.

    Challenges to better BRT

    The key challenge to implementing segregated

    bus lanes, especially in narrow roads carrying

    high volumes o private motorized trafc, is only

    political. Exemplary interventions in constrained

    widths are observed in Guayaquil, Quito, and

    Mexico City. Hence, we provide BRT templates or

    streets as narrow as 18 m in this manual.

    Treating BRT only as a road inrastructure

    improvement leads to low capacity and poor

    system quality. Besides good physical design,

    successul implementation o BRT requires

    system management, operations planning, a

    dedicated BRT bus eet with easy boarding and

    alighting, and sound placement o stations.

    BRT can become a barrier to pedestrian and

    cyclist movement i at-grade crosswalks are notprovided at reasonable intervals. Passengers

    may have trouble reaching bus stations unless

    pedestrian reuges and trafc calming measures

    improve pedestrian saety.

    Finally, BRT requires steady enorcement to

    keep private vehicles rom using BRT lanes or

    obstructing the path o BRT buses at intersections.

    Design criteria and standards

    BRT designs should satisy the ollowing:

    Exclusive bus lanes must be provided in thecenter o the street except on small streets

    where mixed trafc runs as one-way on only

    one side o the street

    The width o a BRT lane is 3.3 m, plus buer

    space next to mixed trafc

    At crossings, a 1 m pedestrian reuge between

    mixed trafc and a BRT lane is needed

    Centrally located BRT stations require 3 m

    (preerably 4 m) in the cross section. Larger

    widths may be required i demand is high

    Sae pedestrian access via crosswalks elevated

    to the level o the ootpath (e.g. +150 mm)

    Stations should be placed 37 m or more o

    intersection stop lines to allow sufcient space

    or bus and mixed trafc queues

    To achieve capacities as high as those o

    metro systems, passing lanes, substations, and

    express services are required at BRT stations

    Cycle parking is needed at stations

    Figure 2.13 BRT rees buses rom trac congestion

    so that they are not held up in mixed trac.

    However, the location o this BRT station directly

    at the intersection creates unnecessary trac

    congestion, resulting in longer delays or bus

    riders and private vehicle users alike.

    Figure 2.12 This BRT station acilitates high quality

    service or passengers since it is located in the median

    and operates with level boarding. It also leavessucient queuing space at the intersection.

    parking lanes are discontinued.

    Note that even narrower rights-o-way are capable o supporting BRT

    systems. Reer to the 18 m and 24 m templates in chapter 4 or urther

    provided (below). The design provides two docking bays to increase system capacity.

    Docking bays should be staggered to reduce riction between passengers boarding and alighting on opposite sides. Docking

    bays or 18m articulated buses (below) consist o two openings: a ront opening o 3 m and a rear opening o 6 m.

    single corridor in a city centre context.

    In this example, the station is comprised o two modules.

    Each module has one docking bay per direction, plus

    queueing space or one bus behind the docking bay. A 21 m

    On-street parking2.5What on-street parking achieves

    On-street parking is clearly designated, managed,

    charged, and restricted in volume, enabling access

    to nearby properties without disturbing the ow

    o motor vehicles, pedestrians, and cyclists.

    Signifcance o on-street parking

    On-street parking is seen as being avorable to

    local business, even though successul business

    districts without on-street parking can be ound

    around the world.

    Free on-street parking subsidizes private vehicles.

    This subsidy is undesirable because it increases

    private motorized trafcwith all o its negative

    side eects, including congestion, air pollution,

    and reduced saety or pedestrians and cyclists.

    Hence, on-street parking should be restricted, and

    whatever parking is available should be charged,

    not only to counter the mode shit to private

    vehicles, but also to serve as signifcant source o

    unds or the improvement o public space, public

    transport, and non-motorised transport.

    Challenges to better on-street parking

    On-street parking areas generally are not

    designated ormally. Instead, parking accumulates

    organically near points o attraction. On streets

    with high vehicle volumes, parking may cause

    delays, especially or buses, and may pose a saety

    hazard.

    Where ootpaths are not provided, haphazard

    parking can create difcult conditions or

    pedestrians, who are orced to weave their way

    through the parking area or walk on the right-

    hand edge o the parked vehicles, in moving

    trafc. When ootpaths and cycle tracks are

    provided, they oten become parking lots or cars

    and two-wheelers unless physical barriers or law

    enorcement prevent such encroachment.

    The lack o an adequate parking ee gives the

    impression to users that parking is a deemed

    right. Instead on-street parking should be treated

    as a premium service. A high charge encourages

    short duration parking, thereby allowing multiple

    users to access the same spot. It also promotes

    the use o o-street parking.

    Design criteria and standards

    In contrast to mobility-oriented elements such as

    carriageways, cycle tracks, or ootpaths, parking

    involves ewer design constraints as it does not

    require continuous linear space.

    Parking should satisy the ollowing:

    Parking areas should be allotted ater

    providing ample space or pedestrians, cyclists,

    trees, and street vending

    Tree pits can be integrated in a parking

    stretch to provide shade. Otherwise, shaded

    street elements, such as ootpaths, may be

    encroached by parked vehicles

    Near intersections, parking lanes can be

    discontinued to reduce conict and to give

    additional vehicle queueing space

    Dedicated cycle parking should be provided

    at public transport stops and stations and in

    commercial districts

    Figure 2.19 This street provides semi-ormal parking

    areas that are accessed rom a service lane. The design

    acilitates the collection o parking ees by delineatingparking and no-parking zones and reduces the number

    o confict points on the main carriageway.

    Figure 2.20 When pedestrians encounter

    haphazardly parked vehicles, they generally walk

    next to moving vehicles because this part o the

    street oers the most direct route.

    Figure 2.22 Parallel parking or cars is the most ecient

    parking layout in terms o the number o vehicles

    relative to the area occupied. The same parking lane

    can be used as perpendicular parking or two-wheelers.

    urniture and vending.

    Cycle tracks next to parking

    lanes require a 0.5 m buer

    so that car doors do not open

    over the cycle track.

    In service lanes, parking should be located on

    the let side so that passengers do not spill over

    on the cycle track when they exit a vehicle.

    crossings. However, they are surmounted anyway.

    When large groups o pedestrians attempt to

    cross, they will spill over into the carriageway (see

    Section 2.16 or more on pedestrian crossings).1

    Design criteria and standards

    Medians should satisy the ollowing:

    I the curb-to-curb carriageway width is 11 m

    or narrower, periodic pedestrian reuges can

    enhance saety

    On an artery where the curb-to-curb

    carriageway width is 12 m or wider, a

    continuous median surmountable by

    pedestrians (maximum 150 mm) is advised

    In order or the median to unction as a sae

    pedestrian reuge, a minimum width o 1 mshould be provided. A cycle reuge should be

    2 m wide

    Guardrails and high curbs are discouraged

    because they hinder pedestrian and cycle

    movements. They should be provided only

    on carriageways with a curb-to-curb width

    o 18 m or larger, with a break or pedestrian

    crossing every 50 m

    Adjacent to BRT lanes, longer stretches o

    guardrail can be provided, with breaks only at

    ormal crossings (150200 m)

    1 In special cases such as expressways that areuninterrupted or kilometers, medians should becompletely unsurmountable rather than simplydifcult to mount. However, creating expressways inurban environments is strongly discouraged.

    What good medians achieve

    A good median reduces conict between opposite

    directions o trafc and acts as pedestrian reuge

    but has requent enough breaks to discourage

    motor vehicle users rom driving in the wrong

    direction.

    Signifcance o medians

    Medians can help streamline trafc and ensure

    saety on higher-speed streets where there is a

    risk o collisions involving right-turning trafc.

    In addition, they prevent speeding drivers rom

    crossing into the opposing trafc lane.

    Medians improve saety or pedestrians by

    unctioning as reuge islands, which allow

    pedestrians to cross one direction o travel at a

    time. It is much easier to fnd an adequate gap in

    hal the trafc ow rather than all o it.

    Central medians can accommodate other

    elements such as landscaping, pedestrian and

    cycling boulevards, and parking.

    Challenges to better medians

    Medians that extend too ar without any

    opportunities to cross, turn right, or make a

    U-turn make the other side inaccessible and

    unnecessarily increase the total distance traveled.

    They encourage vehicle movement on the wrong

    side, thereby compromising saety. Hence, the

    provision o breaks in a median at appropriate

    intervals is critical.

    Sometimes, guardrails or high curbs physically

    separate directional vehicle ows to avoid

    pedestrian crossing in places other than zebra

    Figure 2.27 This median ence is continuous,

    orcing pedestrians to c limb over. There is no

    sae reuge, so pedestrians oten stand in the

    carriageway while waiting or a break in the

    What good landscaping achieves

    Landscaping improves the livability o streets.

    It plays a unctional role in providing shade to

    pedestrians, cyclists, vendors, public transport

    passengers, and other street users. It also

    enhances the aesthetic qualities o streets.

    Signifcance o landscaping

    Eective greening with street trees reduces

    the street temperature, making it comortable

    or people to walk, cycle, or gather or social

    activities, even during summer aternoons. This

    is especially important in places with a humid

    climate or harsh daytime sun. On a larger scale,

    plants keep a city cool by reducing the urban heat

    island eect.

    Trees also capture dust and remove glare. During

    storms, they reduce wind velocity. Additionally,

    trees can help reduce vehicle speeds by reducing

    the actual or the perceived width o a street.

    Landscaping can beautiy a street, providing an

    umbrella canopy and adding colors, ragrances,

    and textures. The potentially varied character

    o ora along a street can make it a more

    memorable space. A well-designed landscape

    promotes a sense o ownership among nearby

    residents or shop owners such that they

    contribute towards its upkeep. Finally, landscaping

    can incorporate ruit-bearing and medicinal or

    religious trees and shrubs.

    Challenges to better landscaping

    Good landscaping in cities with hot climates

    employs trees extensively to create shaded street

    environments. Unortunately, greening o streets

    is oten seen only as a beautifcation exercise,

    avoring low shrubs and owers, which serve an

    aesthetic unction but do little else to improve

    comort or pedestrians and cyclists.

    Trees are oten avoided out o ear that drivers

    will run into them, or that they may disturb the

    carriageway, storm water pipes, and other util ities.

    Design criteria and standards

    Landscaping should satisy the ollowing:

    Appropriate distance between trees to provide

    continuous shade, depending on the individual

    trees canopy size and shape. In dry climates

    where trees do not grow very ast, closer

    spacing is necessary

    Tree pits locations should be coordinated with

    the position o street lights

    Medium-height vegetation should be trimmed

    directly adjacent to ormal crossings to

    improve the visibility o pedestrians and

    cyclists

    Trees with high branching structures are

    preerable

    Tree pits should have dimensions o at least

    1.5 m by 1.5 m to accommodate roots at ull

    maturity. On narrow sidewalks, the samesurace area can be achieved with 1 m by

    2.25 m tree pits. Hume pipes can lower the

    level at which roots spread out, thereby

    reducing damage to road suraces and

    underground utilities

    Figure 2.29 Landscaping, especially tree cover, can

    make the streetscape more beautiul and can improve

    comort or pedestrians and cyclists.

    Figure 2.30 Tree lines should be arranged so that shade

    can enhance the psychological separation between the

    2.9 Street urniture and amenities

    Figure 2.32 Even inexpensive street urniture can

    acilitate a wide range o activities.

    Figure 2.33 Street urniture should be positioned

    so that it does not obstruct pedestrian and

    cyclist movements. This garbage can makes it

    impossible to continue walking on the ootpath.

    I such obstacles are requent, pedestrians will

    not use ootpaths at all.

    What good street urniture achieves

    Street urniture provides people places to si t, rest,

    and interact with each other. Street urniture also

    includes services-related inrastructure, such as

    trash cans, street vending, and signage.

    Signifcance o street urniture

    Street urniture can help make a street an

    attractive place to spend time. When positioned

    on narrow shared streets, benches, tables, street

    vending spaces, and other urniture can also

    unction as trafc calming elements.

    Vending stands, tables, roos, and water taps

    can support the ormalization o street vending

    (see Section 2.10) and promote better sanitary

    conditions.

    Finally, other street urniture, such as way-fnding

    signs and bus stops, provides inormation.

    Challenges to better street urniture

    Poorly located street urniture occupies space

    rather than serving a useul purpose. Furniture

    and signposts placed in the middle o a ootpath

    can reduce or eliminate the clear space available

    or walking.

    Maintenance o street urniture elements is oteninadequate. For example, broken benches are not

    repaired promptly or garbage bins overow with

    rubbish because they are not emptied regularly.

    The installation o street urniture should be

    accompanied by a maintenance plan involving

    local partners.

    Design criteria and standards

    Furniture and amenities should be located where

    they are likely to be used. Furniture is required

    in larger quantities in commercial hubs, market

    areas, crossroads, bus stops, railway stations, and

    public buildings.

    Most street urniture, especially benches and

    tables, should be placed where it receives shade.

    Otherwise, it will become too hot to be used

    during the daytime and, in that case, is more

    likely to be vandalized.

    Furniture should be located where it does not

    obstruct through movement. Bulbouts in parking

    lanes and street vending islands in shared streets

    are great places to install urniture. Similarly,a landscaping strip can be broken with street

    urniture on hardscaped spaces.

    On streets with large numbers o pedestrians and

    commercial activityespecially eateriestrash

    bins should be provided at regular intervals

    (possibly every 20 m). On streets with lower

    pedestrian densities, trash bins can be provided

    according to adjacent land uses or street activity.

    2.10 Spaces or street vending

    Figure 2.36 Inormal activities enliven public spaces

    while providing a source o livelihood or vendors and

    inexpensive goods or customers.

    Figure 2.37 Vendors may be more willing to participate

    in the upkeep o the spaces they use i municipal

    authorities provide ormalized areas or street vending.

    What street vending achieves

    Well-planned spaces or street vending provide

    citizens with secure and dignifed areas or the

    trade o goods and services.

    Signifcance o street vending

    Street vending oers convenient access to

    economical goods and services or a wide range

    o income groups, especially the poor. In India,

    street vendors constitute 2.5 percent o the urban

    population.1 Assuming a household size o fve

    and multiple income sources, over 10 percent o

    urban households likely depend on street vending.

    Hence, it is important to provide improved and

    ormal street vending areas, especially on

    major streets and near public transport nodes.

    Well located street vending reduces trip lengths

    by allowing people to shop on the way to other

    destinations. Spaces may be rented out to and

    managed by cooperatives. Formalizing street

    vending may be seen as a means o poverty

    alleviationrom point o view both o the vendor

    and o clients unable to aord more expensive

    goods and services in ormal establishments.

    Well-planned vending zones can make urban

    space more vibrant, promote social supervision,

    and improve public saety.

    Challenges to better spaces or street vending

    Existing street design ails to address street

    vending. Very ew streets in India in have spaces

    designated or vending. As a result, vendors

    1 Sharit Bhowmik, Street Vendors in Asia: A Review,Economic and Political Weekly (May 28June 4, 2005).

    end up using spaces intended or others such

    as ootpaths or the carriageway. Where space is

    limited, conicts among users lead to skepticism

    that vending is a legitimate activity in public

    streets. A common perception is that street

    vending makes a city look antiquated, dirty, and

    impoverished. Too oten, street vendors play a

    cat-and-mouse game with the administration

    and police, which is costly and inefcient or both

    sides.

    In reality, there is usually sufcient space or

    the ormal and inormal to coexistas shown

    in the street templates. And there are numerous

    successul examples o ormalised street vending

    around the world.

    Design criteria and standards

    The ollowing criteria should be ollowed:

    Street vendors should be accommodated

    where there is demand or their goods and

    servicesnear major intersections, public

    transport stops, parks, and so on

    Supporting inrastructure, such as

    cooperatively managed water taps, electricity

    points, trash bins, and public toilets, should be

    provided

    Vending areas should be positioned so asto ensure the continuity o cycle tracks and

    ootpaths

    Storm water drainage2.13

    Figure 2.46 This design lets water all into a catch pit in

    the buer and then into pipes under a cycle track. The

    level o the drain is below that o the cycle track.

    Figure 2.47 The joint between the drain cover

    and the surace o a cycle track is substandard

    and the placement o the drain in the cycle track

    means that cyclists ride through the deepest

    water in the cross section.

    What good storm water drainage achieves

    Adequate and efcient storm water drainage

    prevents water logging and erosion.

    Signifcance o storm water drainageUnder-investment in storm water drainage

    results in major longitudinal storm water ows,

    which can erode the street surace. Deteriorated

    suraces may cause accidents and thus imply

    costs beyond direct maintenance expenses. In

    ooded areas, pedestrians and cyclists are orced

    to make their way through uncomortable and

    potentially dangerous terrain hidden under the

    waters surace. Ater the water drains away, the

    remaining mud and debris act as a deterrent to

    walking and cycling.

    Challenges to better storm water drainage

    The design o many streets places pedestrians and

    cyclists at the lowest point in the cross section,

    orcing them to wade through water and mud

    during the rainy season.

    Drains are oten placed in an ad-hoc manner and

    are not leveled with the surrounding road surace.

    Design criteria and standards

    Drainage acilities should meet the ollowing

    criteria:

    Catch pits should be located at regular

    intervals, depending on their size and the

    catchment area, and at the lowest point o the

    street cross section

    The lowest point in the cross section should

    occur on the carriageway. Cycle tracks,

    ootpaths, bus stops, and street vending areas

    should be at a higher level

    Drain suraces should be at grade with the

    surrounding street surace unless provided in

    landscaped areas

    More environmentally benign approaches suchas landscaped swales improve groundwater

    recharge, reduce storm water runo, and

    improve the overall livability o a street. Swales

    range in size rom tree pits and landscaping

    strips to large low-lying neighborhood parks.

    Swales are most appropriate on wide rights-

    o-way with large areas o unused space, but

    not in constrained environments where they

    take away space rom pedestrians, cyclists, and

    street vendors

    The number o storm water lines in thecross-section should be minimized to keep

    construction and maintenance costs low. For

    example, an equal number o catch pits can be

    accommodated on two instead o our lines i

    they are placed strategically

    Gratings should be designed so that they do

    not catch cycle wheels

    Figure 2.49 Storm water drainage inrastructure can be integrated

    with medians to reduce construction and maintenance costs.

    In this design, the lowest elevation is at the center o the cross

    section. Water drains through vertical grates into catch pits

    located under pedestrian reuge islands.

    This design is cost eective or three reasons:

    (i) a single longitudinal pipe, connecting the catch pits under thecenter o the road, is sucient to drain the entire road section; (ii)

    manholes and catch pits are integrated, reducing the complexity

    o the design; and (iii) the catch pits and manholes, located in the

    median, are well protected rom heavy trac and are less likely to

    need replacement.

    The appropriate ll material or a swale depends on

    the periodicity o rainall. In locations with steady

    precipitation over a long rainy season, a simple soil ll

    is adequate, while in climates with inrequent rainall,

    a more porous material is necessary i the swale is to

    Figure 2.53 Access boxes or underground utilities should not

    constrain the space needed or through movement. I it is not

    possible to place utility boxes on private easements, the ideallocation is in line with tree pits, to avoid conficts with pedestrian

    movements.

    I there is no way to avoid placing a utility box in the pedestrian

    movement zone, then it is essential to orient the box parallel to the

    street. Placing the box perpendicular to the street, where it stands

    directly in the way o pedestrians, is unacceptable.

    Figure 2.54 The placement o underground utilities should be coordinated with the location o street trees so

    that the trees are not disturbed i utilities are dug up or maintenance or replacement. Telecommunications,resh water, and electricity lines generally can be accommodated within a 1.52 m wide area at the edge o the

    right-o-way. Sewage and storm water lines are usually placed closer to the center o the cross section.

    Trafc calming elements2.15

    Figure 2.55 This let-turn pocket is raised and textured,

    helping to reduce car speeds and improving saety or

    cyclists who must merge with the let-turning cars i

    they wish to continue straight through the intersection.

    Figure 2.56 This stone block in an alley shuts out cars

    and trucks and slows other vehicles by narrowing the

    space through which they can pass.

    What good trafc calming achieves

    Well-designed trafc calming elements ensure

    pedestrian and vehicle saety by reducing at least

    the speedand potentially also the volumeo

    motor vehicles.

    Signifcance o trafc calming

    The increased use o private vehicles necessitates

    trafc calming to ensure that streets remain

    sae or pedestrians and cyclists. Trafc calming

    elements are particularly important in places

    where large numbers o children are present, such

    as schools, parks, and residential areas.

    Given the high rates o noncompliance with

    painted zebra crossings and even trafc lights, the

    most eective way to increase the saety o non-motorised users is to slow down motorised trafc

    orcibly through physical measures such as speed

    humps, raised speed tables, and bollards.

    Challenges to trafc calming

    Trafc-calming elements are oten implemented

    on smaller residential streets where speeds

    are already relatively low. On arterial streets,

    trafc calming is rejected on the grounds that it

    hinders trafc ow. A more balanced approach is

    necessary, especially or arterial streets that alsoaccommodate large volumes o pedestrians.

    Some trafc calming elements, such as speed

    bumps and speed tables, are easy to implement,

    but others, including roundabouts and textured

    pavements, are difcult to construct and may

    appear expensive. However, trafc calming

    can provide major benefts at a nominal

    expense compared to the overall cost o road

    inrastructure. Roundabouts have the beneft o

    improving both saety and trafc ow.

    Design criteria and standards

    Trafc calming slows down vehicles through

    one o the ollowing mechanisms: vertical

    displacement, horizontal displacement, real or

    perceived narrowing o the carriageway, material/

    color changes that signal conict points, or the

    complete closure o a street. Trafc calming

    can take dierent orms depending on the

    context, and is most eective where two or more

    mechanisms are combined. Typical orms o

    trafc calming include speed humps and raised

    pedestrian crossings (see section 2.16), both o

    which rely on vertical displacement to reduce

    vehicle speeds.

    Criteria or selecting appropriate elements are:

    No restriction o pedestrian and cycle

    connectivity

    Trafc and pedestrian volumes

    Frequency and types o accidents

    Road and carriageway width or intersection

    size

    Trafc mode to be calmed. For example, astreet might be closed to cars but let open or

    cyclists and pedestrians

    Severe speed bumps are uncomortable or

    cyclists, rickshaws, and animal-driven carts.

    Figure 2.57 Trac calming methods

    (a) The parking lane alternates between the two sides o this 12 m street,

    preventing vehicles rom speeding. The alternating obstacles are known as

    chicanes.

    (b) In this shared space design, vehicles need to navigate around pedestrian

    islands o varying shapes, sizes, and locations wi thin the right-o-way. The

    islands provide space or street vending, socialising, and other activities.

    (c) In order to improve saety at the ormal pedestrian crossing, the medianhas been widened to 3 m. The narrower carriageway induces vehicle users

    to slow down beore they reach the crossing. The crossing itsel, raised to

    +150 mm, serves as an additional trac calming element.

    (d) Wherever access requirements o private properties permit, service

    lanes may be discontinued to create street vending and bus stop zones. (See

    also Section 2.10.)
