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.

Shared zone Mobility zone Shared zone

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

rapid transit lanes.

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.

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
Manhole covers should be avoided and,
i unavoidable, should be level with the
surrounding surace
Dierence in level and surace material or
distinction rom other street elements
Continuous shade through tree cover
Elevation above the carriageway (e.g. +150 mm)
that allows or storm water runo
A buer o 0.5 m between the cycle track and
parking areas or the carriageway
At property access points, the cycle track
remains at the same level and vehicle access is
provided by a ramp in the buer

Figure 2.11 In a slow-speed local
street (below 30 km/h), the
optimum width or a carriageway
is 3 m or one-way movement and
4.5 m or two-way movement.
In a collector street, the optimum
width or the carriageway is 5.5 m
per direction.
In local streets that
need to accommodate
buses and trucks,
the width o a two-
way carriageway canvary between 6 and
6.5 m, depending on
the volume o heavy
vehicles.
In arterial streets, the optimum
widths or two and three implied
lanes are 6 m and 8.5 m, respectively,
in each direction. When considering
carriageways wider than 6 m perdirection, one should keep in mind
that they easily lead to excessive
speeds, wrong-way driving, and
encroachments such as parking.

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.

Figure 2.15 A 30 m right-o-way can accommodate BRT along with
pedestrian ootpaths, cycle tracks, on-street parking, and a local
street carriageway. In order to accommodate the BRT station, the

vending, turnstiles, boarding/alighting, and internal circulation. For stations with lower demand, a single entrance may be
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.

Figure 2.17 Passing lanes can increase passenger capacity o
a BRT system by allowing express buses to overtake local
buses at certain stations. The Transmilenio BRT system in
Bogot, Colombia, carries 45,000 passengers per hour per
direction through the use o passing lanes. Passing lanes
also may be required i separate routes converge on a
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.
Figure 2.21 Bulbouts

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

(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

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.

(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.)

Figure 2.60 Formal pedestrian crossings, in which
pedestrians remain at the same level as the ootpath
(+150 mm) and vehicles pass over ramps, are
required on major streets.
Between ormal crossings, hardscaped pedestrian
reuge islands should be provided at intervals o
approximately 50 m.
At both ormal and inormal crossings, bulb-outs into
the parking lane reduce the total crossing distance.

In this section we provide a collection o
street templates that oer varying degrees
o pedestrian-riendly design; cyclist, public
transport and private motor vehicle mobility;
and on-street parking. Each template contains a
ground plan at a scale o 1:500 and a cross section
at a scale o 1:250. I the templates cross sectionchanges, such as in case o a meandering street
(see template 9A) or a BRT corridor (see template
24F), we provide more than one cross section.
In the ollowing pages we have grouped the
templates under thematic headers based on our
characteristics:
Pedestrian mobility and access
Cyclist mobility
Parking and property access
Private vehicle mobility
The templates are then shown in order o
increasing street width. Templates are provided
or standard street widths: 6, 7.5, 9, 12, 18, 24, 30,
36, and 42 m. Each template can be adjusted or
a slightly wider right-o-way by increasing the
width o any element except the carrriageway and
parking lanes.

Small streets prioritise pedestrians by reducing motor vehicle
speeds. Islands provide space or street vending and socializing
while also serving as trafc calming elements. Parking, islands,
and other elements in alternating locations prevent vehicles
rom speeding. Since speeds remain low, cyclists can saely travel
in mixed trafc.

These templates prioritize pedestrians, creating sae spaces or
children to play and or street vendors to conduct business. They
can serve as key non-motorised transport links in a citys street
network. The service lane allows or property access but is not
meant to unction as a conduit or through trafc.
These templates oer generous space or motor vehicle mobility
but do not have cycle tracks. They may be acceptable i nearby
streets already provide sae cycle acilities.

Median cycle tracks reduce the
possibility o encroachment on
the cycle track by parked vehicles.
Proper signal phasing is necessary to
ensure that conicts are mitigated at
junctions. Trees should be planted in
the median to shade the cycle track.

Cycle tracks should be designed to ensure continuity. At
property access points, the cycle track and ootpath stay at the
same level and vehicle access is provided via a ramp in the cycle
track buer. The cycle track passes behind bus stops to prevent
conicts between cyclists and waiting bus passengers. Tree lines
are positioned to shade both the ootpath and cycle track.

The BRT sections have variouscombinations o elements.
BRT can be implemented on streets
o any width starting at 18 m. One-way systems can be built on narrower
streets.
BRT requires a wider cross section
at stations. On streets with on-street
parking, the extra 4 m can be gained
by temporarily discontinuing the
parking lane. The ootpath should
not be narrowed. Raised speed tables
should be provided at stations to allow
pedestrians to cross the carriageway
saely.
