Station AuditStation Audit is the process to analyse the station
and its components with the design parameters and design standards
by physical survey of the stations. To check the level of service
of the metro station after preparing design criteria of the key
components the metro station, physical survey of the different
metro station of different region of India has been done. To check
level of service of metro stations two different region of metro
stations are physically surveyed:1. Metro stations of Mumbai2.
Metro stations of Delhi
1. Metro stations of MumbaiMumbai is the financial capital of
India. Average trip rate is very high in the Mumbai. The main
Transit System is local trains in the Mumbai. Besides the route of
the local trains, to cater high passenger flow Mass Rapid Transit
System (MRT) has been introduced. There is only one metro route is
working in the Mumbai which is from Versova to Ghatkopar. As only
one metro line is working in Mumbai there is no interchange metro
station in Mumbai.

2. Metro Stations of DelhiDelhi is the Capital of India. Delhi
has the largest metro network working in India. Metro is the main
Public transport system mode in the Delhi. There are different
metro lines of different routes: Yellow line, Red line, Green line,
Blue line, Violet lie, Express Link. Because of these lines are
intersecting with other lines at many junctions there are
interchange metro stations in Delhi where huge passengers are
transferring from one metro line to other metro line.

VersovaVersova is the end station of the only working line of
metro route from Versova to Ghatkopar in Mumbai. Versova is a
terminal station. It is an elevated metro station. As it is the
last station of the metro line, the passenger flow on each platform
is unidirectional. Versova metro station has concourse level on
first floor and platform at second floor.Catchment area: Jai
Prakash road, Seven Bungalows, Model town, G7 mall, New Versova
link road, Kokilaben Dhirubhai Ambani HospitalStation Entries
FIGURE: Different entries for metro station at Versova metro
stationThere are different entries for enter and exit to metro
station of Versova from ground level. Entry from gate 1 is from
seven bungalow road bus station which has staircase to enter the
metro station. Entry from gate 2 is from Model Town road which has
escalator for upward movement to enter the station. Entry from gate
3 is at same side but it has kiss & ride facility for the auto
rickshaws. There is a staircase provision to enter the station at
gate 3. Entry from gate 4 and gate 5 is towards New Versova road.
Entry gate 4 has a provision of escalator for upward movement to
enter the station. Entry from gate 5 has staircase provision to
enter the station. For gate 5 entry has kiss & ride facility
for private vehicles. At this entry auto rickshaw parking is
prohibited. Entry from gate 6 is toward seven bungalow road. It has
kiss & ride facility for auto rickshaws. There are two
elevators for handicapped people to reach the metro station from
the ground level on the both side of road. The capacity of the
elevator is 8 passenger per car. There are two ramps at the
elevator entry so that handicapped passengers can easily access to
the elevators. The slope for the ramp is 1:20 There are two
escalators for upward movement. Passengers usually use escalator to
reach concourse level of the station and use stairs for downward
movement.
Components of StationStation components includes platform,
vertical circulation elements ( escalators, stairs, lifts, ramps),
Automatic fare collection system, station offices, paid zone,
unpaid zone, ticket office, customer care office, ticket vending
machines, different stores etc.
FIGURE: Components on the concourse level at Versova metro
stationOn the concourse floor, there are two side AFC gate entries
which divided the whole concourse floor in two parts: Paid zone and
unpaid zone. For both the entry there are provision of ticket
offices. Vertical circulation elements are in the paid zone to
reach the platform level. There are station office, security
office, first aid room and other retail shops like WH smith and
some food stalls like Havmor on the concourse floor.
FIGURE: Components on Platform level at Versova metro
stationPlatform geometry in Versova metro station is side
platforms. Railway track is in the centre of platform level and
both side are platforms. Platform contains edge strip and warning
strip in yellow colour for safety purpose. There are some seating
provision for old passengers for waiting the train in waiting
areas.

4 car metro is existing working and 6 car metro train is
proposed a passenger trip demand will increase
Platform widthMin 3.5 mIt includes platform edge strip of 500 mm
and warning strip min 485 mm
3.5 m it includes platform edge strip and warning strip
As trip demand is relatively less better level of service can be
achieved by this width
Waiting Area2 waiting areas of 6.25 sqm and 10 sqm
For observed passengers movement it is sufficient
Seating facility4 seats in each waiting area
For non-peak hour train comes after every 7 min so more seating
provision is required
Level of ServiceLOS CPlatform 1: LOS BPlatform 2: LOS CLevel of
service for both the platforms are good and they are less
congested.
Platform geometry of Versova metro station is side platform.
Platform 1 is toward Ghatkopar and platform 1 is toward Versova. As
it is terminal station unidirectional movement of passengers is
done on both the platforms. On platform 1 only upward passenger
movement is done to board the train and on platform 2 only downward
passenger movement is done after departure from train to reach exit
of the station.Space distribution per meter for pedestrian on
platform 1 is 2.53 sq m which is fruin level of service B and for
platform 2 it is 2.05 sq m which is fruin level of service C.
Vertical Circulation Elements (VCEs)Vertical circulation
elements (VCEs) are used to change the level in the station. For
Versova metro station there are two changing levels: 1. Ground
level to concourse level2. Concourse level to platform levelTable:

2 with escalators1 separate stair1 emergency stair
There are 4 stairs at each end of station. Very less people are
using the stairs for regular circulation as there is less
congestion even in the peak time. Mainly they are used in emergency
situation like break down or fire
Generally passengers prefer escalators for upward directional
movement. Very less passengers use stairs for upward movement in
both level. Location of the elevators are very good. On the
concourse floor they open near the AFC entry gate and after AFC
gate entry they located near AFC and centre of the concourse floor.
On the platform level elevators are open in the middle of the rail
track so handicapped passengers have to travel very less to board
the train.
Automatic Fare Collection System Automatic Fate collection
system consists AFC entry gates, AFC exit gates, ticket office,
ticket vending machines, costumer care office and security check at
AFC gates with metal check detectors and luggage scanning
machines.Table: Audited result of AFC system at Versova metro

Waiting period at AFCNot more than a minuteAs the passenger flow
is unidirectional and not high AFC operation is very efficient
As per design guidelines passenger flow at the AFC gates should
be 30-32 passengers per minute but passenger flow at AFC gate is 26
passengers per minute is observed. For the entry gate there is a
security check of each passengers so passenger flow at entry gate
is very much low. There are two ticket office at both the entry of
the station. Use of ticket vending machine by passengers is very
less.
CirculationIn this section typical horizontal circulation of the
passengers in the metro station premises is shown in both the
levels: concourse level and platform level
FIGURE: Horizontal circulation of passengers on concourse level
at Versova metro stationIn figure the horizontal movement of
passengers on the concourse level from entry from ground level to
reach the platform level to board train is shown. Passengers come
from different entries and buy tickets from ticket office or ticket
vending machines. Then they pass through AFC entry gates where
their security check with metal detectors and luggage scanning
machine is done. From the AFC gates they walk towards platform
where they have to board the train. To reach platform they use
different VCEs and their movement is shown in figure.
FIGURE: Horizontal circulation of passengers on concourse level
at Versova metro stationIn this figure horizontal movement of
passengers on platform level is shown. Passengers reach to platform
level by using stairs, escalators or elevators and board the train.
The width of platform is sufficient to have smooth passenger
flow.
Level of Service (LOS)After auditing all the key components of
the Versova metro station, Level of Services of key components like
platform, VCEs and AFC are calculated. As for vertical circulation,
it is observed that maximum passengers prefer escalators to change
the level. Passengers for downward directional movement use stairs
but for upward directional movement use of stairs is very less and
the capacity of elevator is very low. So maximum passenger flow is
come to escalators so that LOS of escalators are very important.1.
LOS of PlatformsPlatform 1: LOS BPlatform 2: LOS C2. LOS for
Escalators and AFC gates
FIGURE: LOS of escalators and AFC exit gates at Versova metro
stationIn the figure Level of Services for the escalators and AFC
exit gates has been shown. Level of Service for downward movement
escalators from platform 2 is very good. The passenger flow is very
good and congestion is very less. Level of service for upward
directional escalators are poor because there are two upward
directional escalators. Present passenger flow coming to the
escalator is very low. Here LOS 3 indicates that escalators for
upward directional movements are in outnumbers. Average passenger
delay on both the AFC gates has been calculated by cumulative delay
of total passengers and divide them to total passengers. Average
delay of passengers at each AFC exit is 26.45 second and 20.7
second which is good.Delay in time to reach station exit from
platform in peak hour at Versova metro station
