EXECUTIVE SUMMARY
INTRODUCTION
Bangalore Metropolitan Transport Corporation (BMTC) has proposed to construct a Traffic and
Transit management Center (TTMC) at the existing Jayanagar 4th ‘T’ Block Bus Depot. The
proposed TTMC at Jayanagar would enhance the reach and effectiveness of the public transport
through integration of local and long distance bus services, and provision of park and ride
facilities and passenger amenities at the TTMC facility.
The proposed TTMCs would include bus terminal, commercial and office spaces, and parking
facility. The change in land use from the existing bus depot facility to the TTMC would generate
new bus schedules, private and IPT vehicular traffic, and pedestrian traffic, which would have an
impact on the traffic conditions in the nearby roadway network and at the access points of the
TTMC. Hence, there is a need to address the traffic impacts of the TTMCs facility not only with
respect to vehicular traffic but also pedestrian traffic for accessibility and circulation.
OBJECTIVE OF THE STUDY
The objective of this study is to identify the Traffic Impacts of the proposed TTMC on the
surrounding roadway network, intersections and at access points of the TTMC and to propose
mitigation measures for the effective traffic operations conditions and circulation of vehicle and
pedestrian traffic on the roadway networks near the proposed TTMC facility.
METHODOLOGY
The methodology adopted for the study is to identify the project generated traffic volumes and its
impact on the roadway network surrounding the project site for existing, project opening Year
2015, and Cumulative Year 2025 conditions. The methodology includes the following
Identification of the number of vehicle trips generated by the proposed TTMC facility
based on the proposed land use.
Analysis of existing plus project traffic operations conditions of the roadway network,
intersections and access points of the proposed TTMC facility.
Develop future base traffic volumes near the study area for the project opening Year 2015
conditions and future cumulative Year 2025 conditions using Travel Demand Model
EXECUTIVE SUMMARY TRAFFIC IMPACT STUDY

Directorate of Urban Land Transport
developed for the Bangalore City for Comprehensive Traffic and Transportation Plan
(CTTP) study.
Analysis of operation conditions of the study roadway networks and intersections in the
study area with and without project for Year 2015 and 2025 conditions.
Identification of mitigation measures required for the effective traffic operation
conditions and circulation in the study area under each scenario.
The Roadway Segments capacity and Level of Service (LOS) were computed based on the
Indian Roads Congress (IRC) standards sourced from Guidelines for Capacity of Urban Roads in
Plain Areas IRC 106-1990. Whereas, the delay and queue lengths at the intersections were
estimated using VISSIM software, which is a micro simulation based software.
EXISTING LAND USE
The proposed TTMC project site in Jayanagar 4th ‘T’ Block is spread over 9.78 acres. The
existing land use includes a BMTC Bus Depot and Karnataka State Road Transport
Corporation’s (KSRTC) staff hospital, staff quarters & guest houses.

SIGNIFICANCE CRITERIA
The following are the significance criteria adopted for the study at the roadway segments and
intersections.
EXECUTIVE SUMMARY TRAFFIC IMPACT STUDY
IV
Directorate of Urban Land Transport
Roadway Segments
If the roadway segment is operating at an acceptable Level of Service (LOS) D or better,
then if addition of project volume reduces the roadway segment LOS to E or F then it’s
considered to be significant impact.
If the roadway segment is operating at LOS E or F, then if addition of project volume
increases the volume to capacity ratio (v/c) of the roadway segment by 0.01 then it’s
considered to be significant impact.
Intersections
If the maximum queue lengths at the intersections exceed the available storage lengths
blocking the adjacent major intersection, then it’s considered to be significant impact.
EXISTING OPERATING CONDITIONS
During the existing conditions, all the study roadway segments were found to operate at an
acceptable LOS D or better except the 39th
Cross Road which was operating at LOS E with a v/c
ratio of 0.94 in the westbound direction. Table I shows the Existing v/c ratios and LOS
conditions at the study roadway segments.
The delay and queue lengths were computed at the study intersections and it was found that all
the study intersections had a delay less than 5 seconds per vehicle except the 39th
Cross Road and
26th
Main Road Intersection which has a delay of 13.4 seconds per vehicle. The maximum queue
lengths at the intersection were found to be less than the available storage length at the
intersections. Table II shows the delay and queue lengths at the study intersections.

PROPOSED PROJECT
The proposed TTMC facility would include BMTC and KSTRC Bus Terminal, Bus Depot,
private vehicles parking facility and commercial development. The BMTC and KSTRC Bus
Terminal include 15 bus platforms each and 25 and 10 idle parking spaces respectively. The
BMTC and KSTRC bus depot would house around 150 and 75 number of bus parking slots
respectively. The commercial development is planned in a 5,75,000 sqft area proposed to include
Hypermarket, Multiplex, retail and restaurants.
The number of vehicle trips generated by the facility was estimated based on the proposed land
use, number of existing bus services near the facility, existing bus depot arrival and departure
schedule, and proposed bus bays at the terminal. The number of total vehicle trips that would be
generated by the TTMC facility during the peak hour condition was found to be 858 passenger
car units (PCU) with 425 and 433 PCUs entering and exiting the facility respectively. The
estimated number of vehicle trips also includes bus and auto rickshaw trips to the facility.
As per the concept plan, the TTMC buses entry point is proposed on 36th
Cross Road & and the
exit on the 26th Main Road and the private vehicles entry and exit point is proposed on the 26th
Main Road. Figure b shows the entry and exit points for the proposed TTMC facility.

EXISTING PLUS PROPOSED PROJECT
During the existing plus project conditions, all the study roadway segments were found to
operate at an acceptable LOS D or better except the 39th
Cross Road which was operating at LOS
E with a v/c ratio of 0.96 in the westbound direction. Table III shows the v/c ratios and LOS
conditions at the study roadway segments.
Based on the significance criteria adopted for the study, the proposed project would have a
significant impact on the 39th
Cross Road segment (between 22nd
Main and 26th
Main Road),
since the v/c ratio would increases from 0.94 in the existing conditions to 0.96 in existing plus
project conditions which is currently operating at LOS E conditions. The project would also have
a significant impact on the 39th
Cross Road segment in westbound direction between 26nd
Main
and 28th
Main Road, since the v/c ratio would increases from 0.76 in the existing conditions to
0.80 in existing plus project conditions also reducing the LOS from D to E.

EXECUTIVE SUMMARY TRAFFIC IMPACT STUDY
VIII
Directorate of Urban Land Transport
During the existing plus project conditions, all the study intersections would have a delay less
than 5 seconds per vehicle except the 39th
Cross Road and 26th
Main Road Intersection where the
delay would increase from 13.4 seconds per vehicle in existing conditions to 18.8 seconds per
vehicle during existing plus conditions. However, the maximum queue lengths at the intersection
were found to be less than the available storage length at the intersections, hence the project
would not have a significant impact at the intersections. Table IV shows the delay and queue
lengths at the study intersections.
FUTURE OPERATING CONDITIONS
The future Project Opening Year 2015 and Cumulative Year 2025 conditions were evaluated for
the future operation conditions of the study roadway segments and intersections with and without
project to propose roadway improvements that need to be in place for the effective traffic
operations and circulation in the study area.
Roadway Segments
Year 2015 Conditions
During the Year 2015 conditions it was found that all the roadway segments would operate at an
acceptable LOS D conditions except the 39th
Cross Road, which would operate at LOS F
conditions. The project would have a significant impact on the 39th
Cross Road segment, since
the addition of project volume increases the v/c ratio of the roadway segments by around 0.05 at
the roadway segments that would operate at LOS E and F conditions

Year 2025 Conditions
During the Year 2025 conditions it was found that all the roadway segments would operate at an
acceptable LOS D conditions except the 39th
Cross Road and 32nd
Cross Road which would
operate at LOS F conditions. The project would have a significant impact on the 39th
Cross Road
and 32nd
Cross Road segment, since the addition of project volume increases the v/c ratio of the
roadway segments by 0.04 and 0.01 respectively at the roadway segments that would operate at
LOS F conditions.
Table V shows the v/c ratios and LOS conditions at the study roadway segments for the Year
2015 and 2025 Conditions.
Intersections
Year 2015 Conditions
During the Year 2015 conditions, addition of project volumes increased the delay by 0.2 seconds
to 5.5 seconds at the intersections. The most significant change was observed at the 39th
Cross
Road and 26th
Main Road Intersection where the delay would increase from 20.1 seconds per
vehicle in Year 2015 without Project conditions to 25.6 seconds per vehicle during Year 2015
without Project conditions and the queue length increased from 97 meters to 135 meters.
However, the maximum queue lengths at the intersections were found to be less than the
available storage length at the intersections, hence the project would not have a significant
impact at the intersections.
Year 2025 Conditions
During the Year 2025 without project conditions, all the intersections would have a delay
varying from 23.1 seconds per vehicle to 79.6 seconds per vehicle. During the project conditions,
due to the changes in the circulation pattern in the study area when compared to the without
project condition the delay at the some of the intersections are reduced and others increased
based on the circulation pattern form the vehicles accessing the project site, for example delay
during the Year 2025 with project conditions at 36th
Cross Road and 26th
Main Road intersection
would be 4 seconds per vehicle when compared to the 45.3 seconds per vehicle during Year
2025 without project conditions, and delay during the Year 2025 with project conditions at
32nd
Cross Road and 26th
Main Road intersection would be65.5 seconds per vehicle when
compared to the 23.1 seconds per vehicle during Year 2025 without project conditions.
EXECUTIVE SUMMARY TRAFFIC IMPACT STUDY
X
Directorate of Urban Land Transport
During the Year 2025 without project conditions most of the intersections would have a
maximum queue length varying from 141 meters to 284 meters. However, the most significant
one would be 39th
Cross and 26th
Main Road intersection where the queue lengths almost
spillover to the adjacent intersection i.e. to 36th
Cross and 26th
Main Road Intersection.
During the Year 2025 with project conditions, the 39th
Cross and 26th
Main Road intersection is
very critical, since the queue length starts building up from this intersection in the southbound
direction and blocks the whole 26th
Main Road in the South Bound direction impacting the 36th
Cross and 26th
Main Road intersection, TTMC Exit Point and 32th
Cross and 26th
Main Road
intersection.
During the Year 2025 with project conditions, the queue length at the TTMC entrance point
along 36th
Cross road would also exceed the available storage length in the westbound direction
from the buses accessing the project site with spill over to the 36th
Cross and 26th
Main Road
intersection.
The project would have a significant impact during Year 2025 conditions at 39th
Cross and 26th
Main Road intersection, 36th
Cross and 26th
Main Road intersection and TTMC entrance point,
since the queue length would exceed the available storage lengths at the study intersections.
Table VI shows the delay and queue lengths at the study intersections.

MITIGATION MEASURES
The mitigation measures proposed are based on the analysis of the Existing, Year 2015 and Year
2025 conditions. The mitigation measures includes the following for the effective traffic operation
and circulation in the study area with the entry of the buses on 36th Cross Road and Exit on the 26th
Main Road
1. 25th Main Road: Converting the existing two way movement between the 39th Cross and 43th
Cross Road to one way movement in the south bound direction.
2. 39th Cross Road: Converting the existing two way movement between the 26th Main and 18th
Main Road to one way movement in the west bound direction.
3. TTMC Buses Entry Point: Construction of one lane of around 4 meters underpass along
the 36th
Cross Road, so that the buses on 36th
Main Road can make a right turn to access
the TTMC without coming in conflict with other vehicles.
4. TTMC Private Vehicles Entry Point: It is proposed to provide an additional lane along
32nd
Cross Road in the south bound direction, to act as a storage space for the vehicles
making right turn to access the TTMC parking facility.
An analysis was also done by altering the entry/exit of the proposed TTMC and identifying the
variation in the traffic patterns in and around the proposed TTMC. It was suggested to provide

RECOMMENDATIONS
The following recommendations were made with respect to the Project Site and the surrounding
roadway network to improve the pedestrian connectivity to the TTMC and also to improve the
vehicle circulation pattern in the study area.
Proposed Project
The proposed TTMC entrance point for the buses should be provided on 26th
Main Road and the
TTMC exit point for the buses should be provided on 22nd
Main Road. The entry and exit for the
pedestrians accessing the terminal is recommended to be provided at either corner of the site
facing the 26th
Main Road to reduce the pedestrians coming in conflict with vehicles accessing
the facility.
Table Top crossing should be provided at all the vehicles access points for the proposed TTMC
facility and the Pedestrian Access to the Bus Terminal should be kept at grade, since pedestrians
will be accessing the terminal from entrance of the TTMC. The entry and exit for the pedestrians
accessing the terminal is recommended to be provided at either corner of the site facing the 26th
Main Road, since this would reduce the pedestrians coming in conflict with vehicles accessing
the facility.
Pedestrian Facility Network
The transformer present at the south east corner of the project site has to be re-located, since the
transformer is blocking the whole pedestrian footpath and the relocation would free up the space
for pedestrian usage.

CHAPTER 1 -INTRODUCTION
BACKGROUND
Traffic and Transit Management Centers (TTMC) is an outcome of Bangalore Metropolitan
Transport Corporation (BMTC) envisaged combined transit management centre for addressing
bus transportation issues of Bangalore in an attempt to enhance the reach and effectiveness of the
public transport system. The Bangalore Metropolitan Transport Corporation (BMTC) has
planned 45 Traffic & Transit Management Centers (TTMCs) in & around Bangalore to cater the
growing number of bus commuters and to provide them with modern amenities.
BMTC has initiated a project for developing TTMC at Jayanagar 4th ‘T’ Block in Bangalore.
The Project Site is a single parcel of land spread over an area of 9.78 acres in Jayanagar 4th “T”
Block. The map below presents the location of the Project Site with respect to the city.

Directorate of Urban Land Transport
TTMCs results in new Bus terminal and also includes commercial office space resulting in new
vehicular and pedestrian traffic generated by the facility, which would have an impact on the
traffic conditions of the surrounding roadway network and at access points to the facility. The
proposed TTMC will also have an impact on the existing traffic circulation patterns and at
intersections surrounding the project site. Hence there is a need to conduct a Traffic Impact study
on the roadway segments and intersections near the proposed TTMC at Jayanagar. In addition,
the pedestrian and vehicle entry/exit should also be suggested in order to reduce the vehicles and
pedestrian conflicts near the project site.
OBJECTIVE
The objective of this study is to assess the potential impact of traffic generated by the proposed
TTMC on the roadway segments, intersections and at access points of the TTMC and to
recommend various roadway improvements and mitigation measures required to ensure safe and
efficient vehicular and pedestrian circulation in the study area upon the completion of project.
PROJECT SCOPE
1. To analyze the existing and future year operation conditions of the roadway segments and
intersections surrounding the project site.
2. Identify Traffic Impacts from the proposed TTMC on the roadway segments and
intersections in the study area.
3. Propose mitigation measures i.e. roadway improvements required to achieve acceptable
operating conditions of the roadway segments and junctions, and efficient circulation
patterns in the study area.
4. Suggest vehicles and pedestrian entry and exit to the TTMC to reduce vehicular and
pedestrian conflicts.

EXISTING SITE ACCESS AND CIRCULATION PATTERN
The BMTC buses access the Depot through 26th
Main Road. The passing by services buses uses
36th
Cross Road and 32 Cross Road to reach Jayanagar 9th
Block and Carmel Convent
respectively. The peak hour bus movement in and out of the depot is during the night and early
in the morning, so there is minimum conflict between the buses and the other vehicles using 26th
Main Road. The buses use the median opening in 26th Main Road to access the Depot. Figure5
shows the buses circulation pattern at the Entry/Exit point of the depot. The gate openings are
used only by the people to access the Quarters/ Hospital.

SIGNIFICANCE CRITERIA
The following are the significance criteria adopted for the study at the roadway segments and
intersections
EXISTING CONDITIONS TRAFFIC IMPACT STUDY
9 | P a g e
Directorate of Urban Land Transport
Roadway Segments
If the roadway segment is operating at an acceptable Level of Service (LOS) D or better,
then if addition of project volume reduces the roadway segment LOS to E or F then it’s
considered to be significant impact.
If the roadway segment is operating at LOS E or F, then if addition of project volume
increases the volume to capacity ratio (v/c) of the roadway segment by 0.01 then it’s
considered to be significant impact.
Intersections
If the maximum queue lengths at the intersections exceed the available storage lengths
blocking the adjacent major intersection, then it’s considered to be significant impact.
EXISTING OPERATION CONDITIONS
The existing operation conditions of the study roadway networks and intersections near the
proposed project site were evaluated with respect to the following to identify the deficiencies
with respect to vehicle and pedestrian traffic
1. Roadway Segments
Volume to Capacity Ratio and LOS
2. Intersections
Delay and Queue Length
3. Existing Pedestrian facilities
Footpath Connectivity and Pedestrian Crossings
Roadway Segments
The Level of Service (LOS) and the capacity of the Roadway segments computed is based on the
Indian Roads Congress (IRC) standards sourced from Guidelines for Capacity of Urban Roads in
Plain Areas IRC 106- 1990. Table 2 provides the LOS standards adopted based on the volume to

The existing peak hour delay (seconds per vehicle) and the maximum queue length (meters) at
the study intersections are shown in Table 4. All the intersections had a delay less than 5 seconds
per vehicle except the 39th Cross and 26th Main intersection which had a delay of 13.4 seconds per
vehicle. The delay of 13.4 seconds per vehicle at 39th Cross and 26th Main intersection can be
attributed to reduced number of available gaps between the vehicles at 39th Cross Road segment
which is operating at LOS E. The maximum queue lengths at the study intersections were found to be
less than the available storage capacity between the intersections.

TRIP GENERATION
The number of vehicle trips generated by the facility was estimated based on the proposed land
use, number of existing bus services near the facility, existing bus depot arrival and departure
schedule, and proposed bus bays at the terminal. The number of total vehicle trips that would be
generated by the TTMC facility during the peak hour condition was found to be 858 passenger
car units (PCU) with 425 and 433 PCUs entering and exiting the facility respectively. The
estimated number of vehicle trips also includes bus and auto rickshaw trips to the facility.
Table 6 shows the estimated number of vehicle trips for the proposed project site during peak
hour conditions.
Table 6: Potential Trip generation at TTMC during Peak Hour
TRIP DISTRIBUTION
The project trip distribution was based on the exiting travel pattern in the study area and also the
project site surrounding catchment area. It was estimated that around 45 percent of the trips
would be generated from the east side of the project site, around 25 percent of the trips would be
generated from the west side of the project site, around 10 percent of the trips would be
generated from the north side of the project site, and around 20 percent of the trips would be

CONCEPT PLAN FOR THE PROPOSED TTMC
The following section describes the proposed concept plan for the TTMC. The Concept plan
proposes to segregate the functional space of the TTMC into 3 floors. Each of these floors is
proposed to handle certain kind of function.
1. The basement floor would comprise car parking space to accommodate 1300 cars.
2. The lower ground floor would accommodate the KSRTC Depot and BMTC Depot, fuel
refilling station and other services.
PROPOSED PROJECT TRAFFIC IMPACT STUDY

Directorate of Urban Land Transport
3. The upper ground floor which will be the ground level would accommodate the BMTC
Bus platforms, KSRTC Bus platforms and idle parking space. Along with these, space for
Commercial Development is provided at this level.
The concept plan is illustrated in Figure 10.
Figure 10 : Proposed Concept Plan
SITE ACCESS AND CIRCULATION PATTERN
Site Access
The Proposed Jayanagar TTMC has a segregated access for the buses, private vehicles and
pedestrians with a total of 6 access points as shown in Figure 11. Access points 1 and 2 open on
to the 36th
Cross road, while all other access points open on to the 26th
Main road. Access point 1
is for the entry of buses into the terminal while access point 6 is for the exit of buses from the
terminal. Access points 2 and 3 are meant exclusively for entrance into the commercial complex
for the pedestrians. Access point 5 is for the private vehicles entry and exit to the parking lots,
while access point 4 is exclusively meant for the pedestrians to access the Bus terminal and the
Commercial Complex.

Site Circulation Pattern
The TTMC bus terminal has 3 bus bays with 15
platforms dedicated to handle the BMTC bus
services. KSRTC Bus Bay is segregated from
the BMTC bus bays. Fifteen angular parking
platforms are provided for KSRTC intercity bus
services. The site circulation pattern is
illustrated in Figure 12.
The BMTC buses that would access this facility
is assumed to be from the following routes,
1. Buses plying towards Jayanagar 9th
Block.
2. Buses plying towards Carmel Convent.
The BMTC and KSRTC buses would access the
facility from the 36th Cross Road and exit on

the 26th Main road. There would be a change in the bus circulation pattern in and around the
study area once the TTMC is operational. Figure 13 shows the existing bus circulation near the
project site while Figure 14 shows the bus circulation pattern after the construction of TTMC.
Based on the concept plan for the Jayanagar TTMC, the conflict points are created at the access
points of the TTMC facility. The concept plan entrance and exit points were retained, since it
provided better circulation near the study area. Figure 15 depict the conflicting movements at the
access points of the proposed TTMC.
1. Conflict point at the TTMC Exit on 26th Main Road
Conflict point would arise at the exit point of the TTMC, where the buses making a right turn
from the TTMC Exit point on to 26th
Main Road would be in conflict with the northbound i.e.
through movement vehicles.

EXISTING PLUS PROPOSED PROJECT CONDITIONS- LOS ANALYSIS
Roadway Segments
During the existing plus project conditions, all the study roadway segments were found to
operate at an acceptable LOS D or better except the 39th
Cross Road which was operating at LOS
E with a v/c ratio of 0.96 in the westbound direction. Table 7 shows the v/c ratios and LOS
conditions at the study roadway segments and Figure 16 depicts the LOS at the study roadway
segments.
Table 7: Operating conditions- Existing plus Project Scenario
Based on the significance criteria adopted for the study, the proposed project would have a
significant impact on the 39th
Cross Road segment (between 22nd
Main and 26th
Main Road),
since the v/c ratio would increases from 0.94 in the existing conditions to 0.96 in existing plus
project conditions which is currently operating at LOS E conditions. The project would also have
a significant impact on the 39th
Cross Road segment in westbound direction between 26nd
Main
and 28th
Main Road, since the v/c ratio would increases from 0.76 in the existing conditions to
0.80 in existing plus project conditions also reducing the LOS from D to E

CHAPTER4- FUTURE OPERATING CONDITIONS
FUTURE VOLUME DEVELOPMENT
The future peak hour traffic volumes for the project opening year and cumulative year for the
study roadway sections and at intersections were developed using the Bangalore City Travel
Demand Model developed by RITES Ltd. The growth rate obtained from the Travel Demand
Model was used to forecast the future year traffic volumes at the study roadway segments and
intersections. The future traffic projection was done for the Near Term (project opening Year
2015) conditions as well as 10 years from then Cumulative Year (Year 2025) conditions.
NEAR TERM LOS ANLAYSIS
The near term traffic analysis was done for the Year 2015 conditions, since the project is
expected to be built and operational by Year 2015.
Roadway Segments
The study roadway segments were evaluated for the future Year 2015 conditions with and
without the proposed project. Table 9 shows the LOS for the study roadway segments for the
same.

Directorate of Urban Land Transport
During the Year 2015 Without Project conditions, it was found that all the roadway segments
would operate at an acceptable LOS D conditions except the 39th
Cross Road segment between
22nd
and 26th
Main Road, and 26nd
and 28th
Main Road which would operate at LOS ‘ F ‘ and
LOS ‘E’ during peak hour conditions. The project would have a significant impact on the 39th
Cross Road segment, since the addition of project volume increases the v/c ratio of the roadway
segments by 0.01 at the roadway segments that would operate at LOS E and F conditions.
Figure17 depicts the level of service in the Year 2015 with and without the project of the study
roadway segments.

Delay
During the Year 2025 without project conditions, all the intersections would have a delay
varying from 23.1 seconds per vehicle to 79.6 seconds per vehicle. During the project conditions,
due to the changes in the circulation pattern in the study area when compared to the without
project condition, the delay at the some of the intersections are reduced and others increased
based on the circulation pattern form the vehicles accessing the project site.
During the Year 2025 without project conditions, most of the intersections would have a
maximum queue length varying from 141 meters to 284 meters. However, the most significant
FUTURE OPERATING CONDITIONS TRAFFIC IMPACT STUDY

one would be 39th
Cross and 26th
Main Road intersection where the queue lengths almost spills
over to the adjacent intersection i.e. to 36th
Cross and 26th
Main Road Intersection.
During the Year 2025 with project conditions, the 39th
Cross and 26th
Main Road intersection is
very critical, since the queue length starts building up from this intersection in the southbound
direction and blocks the whole 26th
Main Road in the South Bound direction impacting the 36th
Cross and 26th

During the Year 2025 with project conditions, the queue length at the TTMC entrance point
would also exceed the available storage length in the westbound direction from the buses
accessing the project site with spill over to the 36th
Cross and 26th
Main Road intersection.
The project would have a significant impact during Year 2025 conditions at 39th
Cross and 26th

CHAPTER 5 - MITIGATION MEASURES
Based on the analysis, mitigation measures were proposed to improve the traffic operation
conditions in study area. The mitigation measures were proposed to reduce the overall delay and
queue lengths at the intersections. The mitigation measures were also proposed to reduce the
delay and queue lengths at the access points of the TTMC, such that the impact form the vehicles
entering and exiting the facility would have a minimal impact on the adjacent street roadway
network.
The following mitigation measures are proposed for the study area with the entry of the buses on 36th
Cross Road and Exit on the 26th Main Road:
1. 25th Main Road is proposed to be made one-way in south bound direction between 39th Cross
and 43th Cross Road.
2. 39th Cross Road is proposed to be made one-way in west bound direction between the 26th
Main and 18th Main Road.
3. Construction of underpass along 36th
Cross Road, so as to remove conflict point with the
through movement from the buses making a right turn to the TTMC entrance.
4. Provision of storage lane along 26th
Main Road in front of the Project Site in the south
bound direction, so that the through south bound movements would not be blocked by the
private vehicles making right turn through the median opening to the TTMC facility.
5. Closing the median for the south bound movements and taking the vehicles further down
at the 36th Cross/26th Main junction and making them take U turn to access the
commercial complex.

Figure 21: Mitigation Measures
An analysis was also done by altering the entry/exit of the proposed TTMC and identifying the
variation in the traffic patterns in and around the proposed TTMC. It was suggested to provide
the Entry for the Buses to access the terminal on 26th
Main Road and Exit for the Buses from
the terminal to be on 22nd
Main Road.
The following are the mitigation measures proposed with the change in the access:
6. Proposing one-way in East bound direction along 36th
Cross Road from 22nd
Main Road
till 28th
Main Road and one way along 39th
Cross Road along West bound direction from
22nd
Main Road till 28th

Figure 22 represents the mitigation measures 6 and 7.
Figure 22: Mitigation Measures 6 and 7
OPERATING CONDITIONS
The operation conditions at the study intersection after the implementation of mitigation
measures are provided below;
Mitigation Measure 1: 25th
Main Road- One Way
This mitigation measure was aimed at reducing delay and queue length at the 39th Cross Road and
26th Main Road intersection, since the queue length from this intersection in the south bound
direction would exceed the available storage length and spill over blocking adjacent intersection of
36th Cross Road and 26th Main Road intersection, which in turn would block the TTMC-1 access
point increasing the delay at the study intersection in the study area.
The implementation of mitigation measure 1 would reduce the delay and queue length at four of the
six intersections.
MITIGATION MEASURES TRAFFIC IMPACT STUDY
37 | P a g e
Directorate of Urban Land Transport
Mitigation Measure 2: 39th Cross Road - One Way
This mitigation measure, which is a combination of mitigation measures 1 and 2, was also aimed at
reducing delay and queue length at the 39th Cross Road and 26th Main Road intersection.
The implementation of mitigation measures 1 and 2 would reduce the delay and queue length at 39th
Cross Road and 26th Main Road intersection from 81.7 seconds per vehicle to 43.9 seconds per
vehicle and the queue length would also get reduced from 289 meters to 179 meters. The queue
length would be within the available storage length without spilling over to the 36th Cross Road and
26th Main Road intersection.
Alternative Routes
The alternative routes are proposed once 25th
Main Road is made one way. The northbound
vehicles at 25th
Main Road would either make a left turn or right and use 22nd
or 28th
Main Road
to reach their destination.
Figure 22 depicts the proposed alternative route when 25th
Main Road is made one way.

Similarly when 39th
Cross Road is made one way, the alternative routes which can be opted by

Cross Road. Figure 23 illustrates the
alternative route when 39th
cross Road is made one way.

Mitigation Measure 3: UNDERPASS at 36th Cross Road
This mitigation measure is a combination of mitigation measure 1 and 2 and 3. The mitigation
measure 3 was aimed at reducing the queue length at the TTMC-2 access point, which would
have a queue length 178 meters exceeding the available storage length and with spill over blocking
adjacent intersection of 36th Cross Road and 26th Main Road intersection. The proposed location of
the underpass is shown in Figure 24.

The implementation of this mitigation would significant reduce the delay and queue lengths at all
the study intersections, with queue lengths within the available storage lengths.
Mitigation Measure 4: Provision of Storage Space
This mitigation measure is proposed to provide a storage lane of length of minimum 35 meters
on 26th
Main Road in the southbound direction for private vehicles making a right turn to the
TTMC facility. This was based on the analysis which showed the maximum queue length formed
at this access point by the south bound private vehicles making a right turn to the TTMC facility
is around 35 meters (see Table 15, TTMC -1 intersection). The provision of the storage space
would reduce blocking of through movement vehicles by the vehicle making a right turn on to
the TTMC facility. The existing roadway configuration and cross section of the roadway is
depicted in the Figure 26 and the proposed roadway configuration and cross section is depicted
in Figure 27.

Mitigation Measure 5: Without Median opening
Another alternate is proposed by closing the median at the Commercial entry/exit and taking the
vehicles further down at the 36th Cross/26th Main junction and making them take U turn to
access the commercial complex as depicted in Figure 29.

Scenarios
Various scenarios were evaluated and analyzed in order to get the best possible solutions for the
proposed TTMC for an effective traffic operation conditions and circulation of vehicle and
pedestrian traffic on the roadway networks.
Scenario 1:
Scenario 1 is a combination of four mitigation measures. This scenario was taken into
consideration based on the analysis, in order to reduce the queue length and delay at the access
points of the TTMC. The entry of the buses considered in this scenario is on 36th Cross Road and
Exit on the 26th Main Road. Following are the mitigation measures considered for scenario 1:
1. 25th Main Road is proposed to be made one-way in south bound direction between 39th Cross
and 43th Cross Road.
2. 39th Cross Road is proposed to be made one-way in west bound direction between the 26th
Main and 18th Main Road.
3. Construction of underpass along 36th
Cross Road, so as to remove conflict point with the
through movement from the buses making a right turn to the TTMC entrance.
4. Provision of storage lane along 26th Main Road in front of the Project Site in the south bound
direction, so that the through south bound movements would not be blocked by the private
vehicles making right turn through the median opening to the TTMC facility.
The implementation of this mitigation would significant reduce the delay and queue lengths at all
the study intersections, with queue lengths within the available storage lengths. Table 13
represents the operation conditions of the study intersections after the implementation of
Mitigation Measures 1, 2 and 3 and 4.Scenarios considered are depicted in Figure 30.

Scenario 2:
Scenario 2 was evaluated with different operating conditions. In this scenario, the entry of the
buses was considered on 26th
Main Road and exit on to the 22nd
Main Road. It was proposed to
consider the exit on the 22nd
Main Road since the analysis showed a major chaos of traffic on the
36th
Cross/ 26th
main road junction when the exit was provided on the 36th
Cross road. Following
are the mitigation measures considered for scenario 1:
1. 25th Main Road is proposed to be made one-way in south bound direction between 39th Cross
and 43th Cross Road.
2. 39th Cross Road is proposed to be made one-way in west bound direction between the 26th
Main and 18th Main Road.
3. Proposing one-way in East bound direction along 36th
Cross Road from 22nd
Main Road
till 28th
Main Road and one way along 39th
Cross Road along West bound direction from
22nd
Main Road till 28th
Main Road.

4. Closing the median for the south bound movements and taking the vehicles further down
at the 36th Cross/26th Main junction and making them take U turn to access the
commercial complex.
The scenarios considered are depicted in Figure 31. The resulting traffic conditions are shown below.

Scenario 3:
Scenario 3 is similar to scenario 2 with the only variation of the distribution of the buses based
on the existing schedules which are divided into 50% with the number of buses going towards
Jayanagar 9th
Block and 50% going towards Carmel convent. In this scenario also, the entry of
the buses was considered on 26th
Main Road and exit on to the 22nd
Main Road. Following are
the mitigation measures considered for scenario 1:
1. 25th Main Road is proposed to be made one-way in south bound direction between 39th Cross
and 43th Cross Road.
2. 39th Cross Road is proposed to be made one-way in west bound direction between the 26th
Main and 18th Main Road.
3. Proposing one-way in East bound direction along 36th
Cross Road from 22nd
Main Road
till 28th
Main Road and one way along 39th
Cross Road along West bound direction from
22nd
Main Road till 28th
Main Road.
4. Closing the median for the south bound movements and taking the vehicles further down
at the 36th Cross/26th Main junction and making them take U turn to access the
commercial complex.
5. Distribution of the schedules of the buses to 50% plying towards Jayanagar 9th
block and
Carmel convent.

Scenario 4:
Scenario 4 was analyzed based more on the traffic circulation pattern of the surrounding area of
the proposed TTMC. In this, the one ways along the 36th
Cross and 38th
Cross road were
eliminated in order to check the efficiency of the system. However, the one ways proposed along
25th Main Road & 39th Cross road were retained. In this scenario also, the entry of the buses was
considered on 26th
Main Road and exit on to the 22nd
Main Road. Following are the mitigation
measures considered for scenario 4:
1. 25th Main Road is proposed to be made one-way in south bound direction between 39th Cross
and 43th Cross Road.
2. 39th Cross Road is proposed to be made one-way in west bound direction between the 26th
Main and 18th Main Road.

CHAPTER 6 - RECOMMENDATIONS
The following are the recommendations for the proposed project and study area for the effective
operation of study roadway segments, intersections, access points of the TTMC, and pedestrian
accessibility and circulation.
Proposed Project
1. On 26th
Main Road, the spacing between Exit point of Buses and Entry/Exit of private
vehicles should be spaced at least 50 meters apart and Entry/Exit of private vehicles
should be at least 50 m from the 26th
Main Rd and 36th
Cross Road intersection (see
Figure 27).
2. Table Top crossing should be provided at all the vehicles access points for the proposed
TTMC facility.
3. Pedestrian Access to the Bus Terminal should be kept at grade, since pedestrians will be
accessing the terminal from entrance of the TTMC. The provision of subway as shown in
the concept plan is not recommended, since the pedestrians were found to be averse for
using the subways.
4. The entry and exit for the pedestrians accessing the terminal is recommended to be
provided at either corner of the site facing the 26th
Main Road as shown in the Figure 28.
This would reduce the pedestrians coming in conflict with vehicles accessing the facility.
Roadway Network
5. Construction of an underpass along 36th
Cross Road for Buses making a right turn for
accessing the TTMC (see Figure 24).
6. Provision of storage space along 26th
Main Road for private vehicles accessing the
TTMC facility (see Figure 27).
Pedestrian Facility Network
7. The transformer present at the South east corner of the project site has to be relocated,
since it’s currently blocking the whole footpath and the relocation would free up the
space for pedestrian usage and provide connectivity. The existing location of the
transformer is as shown in the Figure 29.

INTERVENTIONS
The following are also the interventions required once the project is operational to have an
effective operational condition near the study area;
1. The following intersections need to be evaluated to know if the intersections needs to be
signalized using the Traffic Signal Warrants for once every two years from Year 2015
and also when metro construction begins for phase II:
32nd
Cross /26th
Main Road.
36th
Cross /26th
Main Road.
39th
