Traffic Management Study Introduction

1 INTRODUCTION- TRAFFIC MANAGEMENT STUDY

Bangalore is 's third most populous city and a well known hub of India's information technology sector, ranked among the top 10 preferred entrepreneurial locations in the world. As a growing metropolitan city in a developing country, Bangalore confronts substantial to its increase in the number of vehicles and a huge increase in the demand on land.

With increasing population and a growing economic base, Bangalore has witnessed a tremendous rise in vehicular growth. The resultant pressure on road spaces is very high, and traffic conditions are increasingly difficult. Nonetheless, there is urgent pressure to find solutions, both short-term and long- term, the ones that can begin to grapple with the complex demands of traffic and transport management.

What adds to the traffic pressure in Bangalore in particular is its very little scope for expansion of roads and the need to use existing roads for smooth movement of vehicles.

1.1 CURRENT SCENARIO IN BANGALORE

The population in Bangalore Urban Region and Municipalities has increased from 30 lakh to 101 lakh over the past four decades. The increase from 41 lakh in 1991 to a drastic increase of 96 lakh in 2011 along with the increasing vehicular growth may be considered the trigger for increased traffic volume leading to delay and congestion.

Fig. 1 represents the population versus vehicular growth over the past four decades. Alongside the exponential growth rate for the year 2021 has also be projected.

Figure 1: Growth Rate of Bangalore

1.2 OBJECTIVE OF THE STUDY

A meeting was held under the chairmanship of the Chief Secretary on 26th Feb 2013, to identify and address the traffic issues of Sadashivanagar and Bellary Road. During which, the following travel constraints were highlighted, namely:

I. Sadashivanagar 1. Traffic congestion on inner residential roads. DULT 1 | P a g e

Traffic Management Study Introduction

2. Unauthorized parking in residential areas (especially evening & weekends)

3. Delays in on-going projects- CNR Rao junction, Sankey Road widening, Ramana Maharishi road widening- between Cauvery junction and Mekhri Circle.

II. Bellary Road 4. Effect of elevated road constructed by NHAI on NH-7

5. Accessibility and Pedestrian infrastructure issues between Mekhri circle and Kodigehalli cross.

In order to identify the existing travel constraints and improve ease of accessibility, as well as decongest the residential ward of the Sadashivanagar, Directorate of Urban Land Transport (DULT) has taken up the study on Traffic Management for Sadashivanagar and Bellary Road.

1.3 METHODOLOGY

The traffic management plan of Sadashivanagar and Bellary Road was aimed to ease and regulate the travel constraints prevailing within the study area. A reconnaissance survey was done to identify the issues pertaining to the intersections, parking, black spots, etc as well as identify the traffic circulation pattern in and around the study area. This was followed by the data collection effort in the from of primary and secondary surveys where primary surveys like traffic volume counts, bus boarding & alighting, Bus passenger opinion, parking surveys, etc were carried out to obtain an idea of the traffic scenario of the study area. The secondary data collected from various agencies comprised of the existing land use patterns, accident details from Traffic Police, Bus route details from BMTC and the proposed improvements in and around the study area which would have a significant effect on the operation conditions of the roadways. The collected data was analyzed to identify the Roadway Segments capacity and Level of Service (LOS), 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 are estimated using a micro simulation based software. The parking surveys were also carried out to ascertain the number of parking space available within the residential area to that of the owned vehicles by residents. The next step was to propose section specific interventions to the identified issue and prepare their of implementation plan. Based on the need of urgency, the interventions were classified as short, medium and long term measures.

Table 1 illustrates the methodology adopted to carry out “Traffic Management Study”.

2 SADASHIVANAGAR

In 1960s and early 1970s, the gardens of the Bangalore (a summer home of the Wodeyar dynasty of ) were converted into a residential neighbourhood. Until 1990s, Sadashivanagar was known as "Palace Orchards," as it was built in the former royal grounds. It was renamed in honor of Karnad Sadashiva Rao, a freedom fighter and philanthropist. Situated right opposite to what is left of the official palace grounds is now a home to many highly placed government officials, ex-governors, film stars and millionaire businessmen. The neighbourhood is also home to various Wodeyar royals.

2.1 LANDUSE

One of the important characteristics in the preparation of a traffic management plan is to study and understand the land use pattern of the study area. Sadashivanagar is a well established posh residential neighbourhood of Bangalore. The land use is mainly of mixed residential type with public spaces such as Indian Institute of Science, the Raman Research Institute, Microsoft Research India, etc. to the north of the study area and an open space of Palace Ground to the east. Although the inner core of Sadashivanagar is mainly residential, the main arterial roads are attracting a lot of commercial activities.

Figure 3 shows the existing land use pattern of the study area.

2.2 ROADWAY SEGMENTS AND INTERSECTIONS

The study area is located around 3.5 km from the CBD of Bangalore, runs along from Mehkri Circle in the north to Bashyam Circle a little way south with towards East and Gutthalli towards South. The major roadway segments surrounding the study area are CV Raman Road,Bellary Road and Sankey Tank Road.Amoung which CV Raman Road,Bellary Road and Sankey Road (between Cauvery Junction / Bhashyam) are six lane divided road and Sankey Road (between Bhashyam and CNR Rao road) is four lane divided road.

Major Roadway Segments include:

The major roadway segments that state the characteristics of the study area are:

1. Sankey Tank Road (CNR Rao Circle–Cauvery Junction)

2. C V Raman Road (Mekhri Circle- CNR Rao Circle)

3. Bellary Road (Cauvery Junction-Mekhri Circle)

Major Intersection in study area

The major intersections that are expected to impact the operational efficiency of the study area are:

1. CNR Rao Circle (Sankey Road/C V Raman Road)

2. Sadashivanagar Police Station (C V Raman Road/New BEL Road)

3. Mekhri Circle (Bellary Road/C V Raman Road)

4. Cauvery Junction (Sankey Road/Bellary Road)

2.3 SURVEYS

A set of primary traffic surveys such as traffic volume counts, speed and delay surveys, road inventory survey, parking opinion Surveys & Bus passenger opinion and boarding and alighting survey, etc were conducted during March- April 2013 in order to assess the traffic and transport scenario.

2.4 EXISTING CONDITION

The existing operation conditions of the study roadway networks and intersections were evaluated with respect to the following to identify the issues with respect to vehicular and pedestrian traffic 1. Roadway Segments- Volume to Capacity Ratio and LOS 2. Intersections- Delay and Queue Length 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 capacity (V/C) ratios at the intersections and its performance.

The existing conditions of the Sadashivanagar Study area reveal that all the study roadway segments in the study area are operating at an acceptable LOS D or better during existing peak hour conditions with V/C ratio equal to or less than 0.77 except the Sankey Road segment between Bhashyam Circle to Circle Maramma Circle which is operating at V/C ratio of 1.46. Table 3 shows the Existing traffic operation conditions of the study roadway segments and Figure 5 depicts the same.

Intersections:

The traffic analyses at the identified intersections are tabulated in table 4. All these intersection generate large amount of traffic and are particularly choked up during the peak hours. CNR Rao circle has recorded a delay of 18.6 sec/veh with queue of 141.2 m in the east bound direction. This queue is only temporary and will be minimized once the proposed underpass at CNR Rao circle is completed and is operational.

DULT 9 | P a g e

Traffic Management Study Sadashivanagar

Cauvery Junction has over the past years become inadequate to cater to the huge growth of vehicular volume. This inefficient carrying capacity of Cauvery junction has also reduced the operational efficiency of Bhashyam circle as well. This may be the reason why Bhashyam circle and Cauvery junction have queue lengths of 293.7m and 511.5 m reported in the south and east bound directions. Windsor Manor has recorded a delay of 192.7 sec/veh with a queue length of 203.4 m in the south bound direction.

2.5 ISSUES AND INTERVENTIONS

This section lists out the issues and relevant interventions proposed to address the travel constraints of Sadashivanagar. The traffic management plan is composed of Short, Middle and Long-Term Plans/measures, where short term measures are the most simplest and immediate to implement with less capital intensive whereas middle term and long term are more section specific measures and more capital intensive.

The approach is as described in sections below.

2.5.1 Cauvery Junction Bangalore’s first “magic box” underpass built under the new cost-effective technology in 2008 was an attempt made by Bruhat Bangalore Mahanagara Palike’s to ease traffic congestion on Bellary Road. However, over the recent years the junction has become incompetent to cater to the large volume of traffic (especially the BIA traffic) leading to traffic congestion and delay.

DULT 10 | P a g e

Traffic Management Study Sadashivanagar

Issues

1. Especially during the peak hours, vehicles particularly buses bound to Mekhri Circle from Windsor Manor are trapped in the bottleneck created on the covered portion of the “magic box” leading to delay and queue length extending from Windsor Manor to Mekhri Circle.

2. The ‘magic box’ is now insufficient to cater increased volume of right turning traffic. Vehicles plying through the “Magic Box” were found to be standing on an unsafe gradient.

Figure 6 illustrate the junction alignment and the traffic volume in PCUs at the Cauvery Junction.

Figure 6: Existing scenario at Cauvery Junction

Interventions

In order to address the immediate need of traffic management at Cauvery Junction, a set of interventions have been suggested.

1. Short Term Measures :

a. Signalization of Cauvery Junction: As a short term measure, an installation a traffic signal has been suggested. As per the existing scenario, the vehicles plying through the magic box find

DULT 11 | P a g e

Traffic Management Study Sadashivanagar

themselves trapped between the longer queues and steep gradients. Thus, Signalization of Cauvery Junction was checked as an alternative for its operational efficiency under two scenarios:

Scenario 1 will include signalization of the junction with vehicles bound right (from Sankey Road towards Winsor Manor) traversing through the “Magic Box” whereas Scenario 2 will include signalization of the junction with vehicles bound right (from Sankey Road towards Winsor Manor) moving at ground gradient i.e the magic box will be closed/filled to provide a safe and effective gradient for the vehicles to traverse upon.

The two scenarios are illustrated in figure 7 below:

Figure 7: Proposed scenarios at Cauvery Junction

Based on the vehicular volume and the available Right of way, signalization of the Cauvery junction has been designed. A total signal phasing plan of 250 seconds with Sankey Road phasing of 70 seconds, Bellary Road phasing of 60 seconds and a pedestrian signal phase of 10 seconds has been proposed.

The proposed signal phase is shown in table 5.

Table 6 represents a comparison of the scenarios proposed for Cauvery Junction. As per the results, the installation of a signal will drastically improve the operational efficiency of the junction i.e the existing delay of 128.5 sec/veh will be reduced to 69.4 sec/veh whereas queue length has increased from 108.9 m to 390.9 m and 511.5 m in the south bound direction with the magic box open and closed scenario respectively. Among the two scenarios, the scenario with magic box closed may be feasible over the magic box open conditions as a queue length of 390.9 m can be accommodated within the available storage length whereas the queue length of 511.5m cannot be accommodated within the available storage length.With respect to throughput, the existing throughput of 3223 will be increased to 4625 and 4631 with the magic box open and closed scenarios respectively.

Signal + Without Magic Box 69 390.9 (SB) 4631

b. Change in Traffic Circulation Plan: Another alternative short term measure is to change in the traffic circulation pattern. This alternative will provide a free right turn for vehicles plying from Bhashyam to Windsor Manor and reduce the conflict between vehicles moving north and vehicles bound from west to south. The change in traffic circulation plans requires the traffic to change lane at Bhashyam Circle on the leg between Bhashayam Circle to Cauvery on the Sankey road owing to which a free right turn will

DULT 13 | P a g e

Traffic Management Study Sadashivanagar be provide at the Cauvery junction. This right turn will be made available on a 5 m wide road which is currently being operated as a 2lane bus bay and a left turning lane for the vehicles traversing from Guttahalli onto Cauvery.

In order to achieve this, there is a need to minimize the conflict points at the Guttahalli, interventions like restricting the left turn and shifting of the bus stop on to the refuge island which located adjacent to the existing bus bay may be necessary. As this change in traffic lane will merge onto the normal traffic at the Palace road vehicular underpass; the vehicular under pass at the Palace road intersection should be made one way ie the vehicles will only traverse from Guttahalli onto Winsor Manor and Vasanthnagar. This making of Vehicular underpass into a one way flow will reduce the conflicts points at the Palace Road intersection.

For a better illustration of the proposed plan, both scenarios i.e existing and proposed traffic circulation plans are illustrated in figure 8 and 9 respectively.

Figure 8: Existing scenario at Bhashyam, Cauvery Junction and Windsor manor Circle

DULT 14 | P a g e

Traffic Management Study Sadashivanagar

Figure 9: Proposed Traffic Circulation at Bhashyam, Cauvery Junction and Windsor manor Circle

The above mentioned alternative will affect the operational conditions at the intersections. Improvement in operational efficiency were observed at few intersections like Cauvery, Guttahalli and Place Road junctions but have negative impacts at Bhasyam and Winsor Manor. The implementation of this alternative has drastically reduced the operations at Winosr Manor where the throughput reduced from 2146 to 1610. Similarly, the likely volume from the banned right turn of Guttahalli has added onto Bhashyam reducing the throughput from 432 to 408 vehicles. Table 7 shows the comparison between the existing and proposed scenario at Cauvery, Bhashyam, Guttahalli, Palace Road and Windsor Manor.

2. Medium Term Measure:

As a medium term measure, a 2 lane one directional grade separator has been proposed. This includes the construction of a grade separator along the west south direction (ie for vehicles from Sankey Road onto Winsor Manor). This proposal has to go alongside the road widening proposal of BBMP to a Right of way of 24m so as to provide 2 lanes for right turning vehicles as well as provide 2.5 lanes for the straight turning vehicles.

This intervention will provide a signal free junction at Cauvery, thereby reducing increased queue lengths at Winsor manor and Mekhri Circle.

Note: This two lane flyover over can also be substituted with a single lane flyover. However, a 2 lane grade separator may be necessary estimating the likely increase of traffic on Bellary Road.

DULT 16 | P a g e

Figure 10 : Proposed scenario at Cauvery Junction

The scenarios with their operational efficiency are tabulated in table 8.As per the analysis, the existing delay of 128.5 sec/veh has been reduced to 8.6 sec /veh and 4.8 sec/veh under the single lane and two lane scenario respectively. The implementation of either a signal or two lanes will increase double the throughput when compared to the existing scenario. Queue lengths have also been reduced from the existing 108.9 m to 71.4 and 43 m in the south bound direction under the single and two lane grade separator scenario.

2.5.2 Bhashyam Circle Bhashyam Circle is a four arm signalized junction located adjacent to Sankey Tank catering to traffic moving in and out of Sadashivanagar and Malleshwaram. This intersection houses a large number of commercial establishments and has witnessed a large increase in vehicular volume over the recent years.

Issues

Although the increase in vehicular volume has no drastic effect on the operational efficiency of the junction, it is observed that the roadway segment of Sankey Tank road between Mariamma Circle and Bhashyam with a narrow carriageway width of 12m is reported to be creating bottle neck leading to longer queue of vehicular traffic during peak hour.

Intervention

As per Revised Master Plan 2015, a proposal to widen the Sankey Road to a ROW 30m has been made. However, due the land acquisition and tree cutting objections the road widening proposal has been delayed.

As a short term proposal, improvising of the signal timing plan has been suggested. The short term proposal is as illustrated below.

DULT 18 | P a g e

Traffic Management Study Sadashivanagar

Figure 11: Existing and proposed signal phasing

The illustrated short term proposal of improvising the signal phasing plan proposes the following changes in signal plan:

1. Increasing the signal phasing time for the circle Mariamma leg from existing 70 seconds to 100 seconds.

2. Decreasing the signal phasing time for the Sadashivanagar leg from existing 60 seconds to 50 seconds.

3. Increasing the signal phasing time for the Cauvery leg from existing 50 seconds to 55 seconds.

Note: The above proposed signal phase is based upon the existing vehicular volume at Bhashyam Circle.

The results on the operational efficiency of Bhashyam Circle are tabulated in table 9. All three parameters ie delay, queue length and throughput have shown better results when compared to the existing conditions. The existing delay of 145.9 sec/veh has reduced to 102.7 sec/veh with increase of throughput from 642 vehicles to 3530 vehicles.

2.5.3 CNR Rao Circle The proposed underpass by BBMP at CNR Rao Circle, likely to be opened by July 2013 has few concerns that have been raised by the residents with respect the safety of vehicles and pedestrians.

In order to analyse the safety issues, it is first necessary to understand the BBMP proposal of the CNR Rao underpass.

CNR Rao underpass is aligned along the East-West direction (Overall length of 330m) as well as East- North direction (Overall length of 145m). The proposed underpass will provide a signal free flow for vehicles bound from Yeshwanthpur to Circle Mariamma and vice versa as well as for vehicles bound from Yeshwanthpur to Mekhri Circle. The proposed alignment is as shown in figure 12.

Figure 12: Alignment at proposed underpass

DULT 20 | P a g e

Traffic Management Study Sadashivanagar

Issues- Concern by the residents

1. The left turning lane from Mekhri Circle to Cirlce Maramma may not be sufficient to cater to the left turning vehicular volume.

2. Conflict between vehicles bound from Circle Maramma to Mekhri Circle and vehicles bound from Mekhri Circle to Yeshwantpur.

3. No designated bus stop on the C V Raman Road between Sadashivanagar and CNR Rao Circle.

Figure 13: Concerned issues on the proposed CNR Rao underpass

Intervention

1. As per IRC 38-1988, design of horizontal curves, the maximum turning radius required for a vehicle greater than 10.973 (bus) m is 13m .The existing alignment has a turning radius of 15m.Thus, the left turning lane may be sufficient to cater to the vehicular volume 1535veh/hr (no. of vehicles turning left).

2. In order to minimize the conflict between vehicles bound from Circle Maramma to Mekhri Circle and vehicles bound from Mekhri Circle to Yeshwantpur, a two phase signal with a pedestrian signal phase of ten second has been proposed. The two signal phasing has been distributed with 45 seconds to the leg moving from Mekhri Circle to Yeshwantpur and 40 seconds to the leg movong from Maramma Circle to Yeshwanthpur. The total signal phasing will be 95 seconds during the peak hour.

3. For better analysis of the need for bus stops with shelters at CNR Rao Circle, a bus stop passenger count and bus passenger opinion survey was conducted. The results of bus stop passenger count are shown in figure 14 and figure 15. As per the survey analysis, the peak hour at CNR Rao Bus stop was found to be between 4:30 PM to 5:30 PM, with a total of 68 and 169 commuters commuting by buses from IISC towards Yeshwanthpur and towards Mekhri Circle respectively.

Further to the Bus Stop passenger count surveys, a set of bus passenger opinion survey were also conducted to identify the accessibility issues at CNR Rao Bus Stop. The results of bus Passenger opinion survey are shown in figure 16 and figure 17.

Figure 17: Trip Purpose Figure 16: Issues with accessibility to bus stops

During the peak hour, majority of the trips made by commuter were found to be work based trips (65%) when compared to the study based trips (35%). The main issues with respect to bus stop accessibility were: no bus shelter (55%) which in turn leads to insufficient passenger service time (30%) or leads to increased walking time (15%).

In order to facilitate the safe and convenient accessibility to the commuters of IISc and BHEL, two bus stops on either side at C V Raman Road about 30 m away from exit ramp of the CNR Rao Underpass has

2.5.4 Traffic congestion in the residential roads of Sadashivanagar The rapid growth in vehicular volume and the insufficient roadway capacity has force motorists to commute through the residential roads (roads adjacent to the main arterial roads).This commute of motorist through the residential roads is mainly to avoid delay and congestion that they will/might incur

DULT 24 | P a g e

Traffic Management Study Sadashivanagar if they traverse through the main arterial roads. A similar case of passing traffic traversing through the residential roads of Sadashivanagar has been reported by the residents of Sadashivanagar.

The residential roads that were found to have increased volume of passing traffic were: 8th Main, 9th Main, 10th Main, 11th Cross,18th Cross and 5th Cross. As per the existing scenario, vehicles bound to Mekhri Circle or Sadashivanagar Police Station from Cauvery or Bhashyam Circle traverse along 18th Cross or 13th Cross road and deviate onto 8th Main before moving onto Mekhri Circle or Sadashivanagar Police Station and this scenario is true in the opposite direction as well.

The number of motorists plying through residential roads during the recent years may also have outnumbered due to the increased delay at Cauvery Junction or due to the delay in the on-going underpass construction at CNR Rao Circle.

This scenario has been represented in figure 19 below.

Figure 19 : Existing Traffic scenario in Sadashivanagar residential layout Interventions

In order to discourage passing traffic from plying through the residential roads of Sadashivanagar, traffic calming measures such as Kerb Treatment, Mini Roundabouts, Serpentine Roadway, etc may be implemented. These are cost effective measures short term traffic management measures which help divert non-residential traffic as well as help retain the aesthetic value of the neighbourhood. Figure 20 is a

DULT 25 | P a g e

Traffic Management Study Sadashivanagar pictorial representation of the type of Traffic Calming measures that can be proposed to the residential area of Sadashivanagar.

Figure 20 : Traffic Calming Measure

The traffic calming measure of kerb extension has been suggested on streets which are likely to have increased traffic volume traversing at high speed. The extended kerb will act as a speed reducing barricade as well as the extended kerb will provide ample waiting area for pedestrians at intersecitons. Mini roundabouts are proposed at intersection that provided poor sight distances at the intersections as well as have high traffic flow.

Based on the intensity vehicular volume plying on the residential roads and the availability of right of way, the following traffic calming measure has been suggested for the residential roads of Sadashivanagar:

Intersections Carriageway Width(m) Traffic Calming Measure

5th Cross/10th Main 10.5 Kerb Extension

18th Cross/Sankey Road 14.2 Kerb Extension

13th Cross/8th Main 13.0 Mini Roundabouts

18th Cross/8th Main 10.5 Mini Roundabouts

Unauthorized parking in the residential roads of Sadashivanagar Another issue that was raised by the residents of Sadashivanagar is Unauthorized parking by the passing traffic.

However, as per the field observations and the parking surveys carried out, it was found that most of vehicles parked on the residential roads belong to the residents and the number of vehicles parked by the passing traffic was found negligible. Surveys finding reveal the following results:

 The number of vehicles owned by the residents is more than the availability of parking space within the premises.

 During the day, most residents were found to park their vehicles on -street, reducing the effective carrying capacity of the roadway segment. Figure 22 is an illustration of the residential parking scenario of Sadashivanagar.

3 BELLARY ROAD

Bellary Road also known as the NH-7 is located in the north of Bangalore. The main connector connecting Tumkur, Hyderabad, Dobbaballapur, Devanhalli,etc has in the recent years seen rapid growth both with respect to traffic and land development. The opening of Bangalore International Airport (BIA) in 2008 has also led to the increased vehicular volume on Bellary Road. This unplanned increase in vehicular growth has led the planning/opening of several grade separators in order to ease the increased delay and congestion.

3.1 LANDUSE

Bellary Road has mixed land use pattern with residential, commercial and industrial establishment’s bordering the main arterial corridors. Major residential areas include R T Nagar, Anand Nagar, Kempapura, ,Ganganagar,etc. It also houses education institutes such as GKVK, Government Vertinary College, Government Flying Training School, Atria Institute of Technology.

3.3 EXISTING OPERATIONAL CONDITIONS

Based on the survey analysis,The existing operation conditions of the study roadway networks and intersections near the study area were evaluated 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

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 as tabulted in table 2.

The results/ outcomes of the survey analysis, the roadway segments along Bellary Road show varying LOS values. This is mainly due to the incresed number of vehicular traffic as well as the on going construction activity by NHAI. The roadway segments are operating at a LOD D or better i.e the V/C ratio is equal to or less than 0.8 except the Hebbal flyover segment which is operating at LOS F and E i.e the V/C ratio ranges between 0.8-1.2.

Table 12 shows the existing traffic operation condition of the study area roadway segments and figure 26 depicts the same.

3.4 ISSUES AND INTERVENTIONS

This section lists out the issues and relevant interventions proposed to address the travel and safety issues of Bellary Road.

3.4.1 Kempapura Entrance Kempapura entrance, located adjacent to the Esteem Mall on Bellary Road is the entrance to the two lane Kempapura Main road. It connects institutes like Presidency College, HKBK College, etc.

In order to minimize the traffic congestion and delay on Bellary Road, NHAI have proposed a set of seven grade separators along Bellary Road between Hebbal and Bangalore International Airport. Amongst one of which is located adjacent to Kodigehalli with its ramp starting around 500 meters from the Kempapura Entrance. This elevated road would results in high speed traffic reaching the Kempapura Entrance causing chaos to both vehicular as well as pedestrian traffic. The identified issues are as listed below.

Issues

1. The Elevated road would generate high speed vehicular traffic reaching the Kempapura entrance causing bottleneck and congestion at the Kempapura Junction as well as the Hebbal flyover located approximately 100m from the Kempapura Junction.

2. Commuter and pedestrian safety has been a major concern. The road widening of Bellary Road to a ROW of 24m, increased vehicular volume plying at higher speed, no bus shelters, irregular median opening have risked the safety of pedestrian at Kempapura Entrance.

DULT 35 | P a g e

Traffic Management Study Bellary Road

3. The 8 lane traffic from the Elevated road (after the construction of the expressway) which squeeze into 6 lanes traffic on the Hebbal Flyover creating chaos.

Figure 27 illustrate issues at the Kempapura Entrance.

Figure 27: Identified issues at Kempapura Entrance

Interventions

1. As a part of short term measure to control the difference in vehicular speed (i.e speed of the elevated road = 80kmph (proposed) and speed of Bellary road=50kmph), a traffic calming measure of provision of rumble strips has been suggested. This will only be provided on the down ramp reaching from BIA to Hebbal. The implementation of which will enable the elevated road vehicles to lower their speed to the speed of the at grade vehicles of Bellary Road. The design criterion is as shown in figure 28 below.

DULT 36 | P a g e

Traffic Management Study Bellary Road

Figure 28: Proposed intervention for the Elevated Road, Bellary Road

2. The following short term measures have been suggested at the Kempapura Entrance in order to ensure safe accessibility to pedestrians:

a. Skywalk at the Kempapura entrance

The existing signal of 20 second at a 5 min interval is insufficient for pedestrians to cross the 6-lane Bellary road. Adding to that, the median also doest provide ample waiting/refuge area to pedestrians. Considering the future growth of vehicles on Bellary Road, the pedestrian signal may tend to increase the vehicular delay and congestion. Thus, removal of the pedestrian signal with a replacement of a 2m wide skywalk will provide safe accessible path to the pedestrian.

Design Elements:

1. Minimum width of walkway should be 2m.

2. A slope of 8% (1 in15) on footbridge ramps, with appropriate resting place/landing is preferable.

3. Tactile tiles with proper lighting are suggested.

Figure 29 is a concept of the proposed Skywalk at Kempapura Entrance.

>>Section at A-A

Figure 29: Concept Plan of Skywalk-Kempapura Entrance

DULT 38 | P a g e

Traffic Management Study Bellary Road b. Shifting of Bus Stop

The existing bus stop without shelter at the Kempapura entrance (eastern side) is located on the shoulder that separates the main lane and the service lane. The 3m wide shoulder is not uniformly barricaded leading to haphazard movement of vehicles to and from the main road. These vehicular movements hinder the pedestrian access to the bus stop. Thus, a suggestion of shifting the bus stop 10 m southwards from the existing bus stop has been suggested. A bus stop with 2 no’s bus bays can be constructed adjacent to the Esteem Mall and connected to the proposed skywalk for better accessibility. c. Uniform barricades

In order to resist the haphazard movement of vehicular and pedestrian traffifc an uniform barricading of the shoulder with 10 m wide opening at a 100 m interval will resist the haphazard of vehicles to and from the main road.

Figure 30 and Figure 31are the illustration of the existing and proposed scenario for the Kempapura entrance.

Figure 30: Issues at Kempapura Entrance

DULT 39 | P a g e

Traffic Management Study Bellary Road

Figure 31: Proposed intervention at Kempapura Entrance The above mentioned scenarios i.e both existing and proposed condition were evaluated in order to check their operational efficiency. As per the analysis, the replacement of pedestrian signal with a skywalk for pedestrian access will reduce the delay at the Kempapura Junction from 12 sec/veh to 0.7 sec sec/veh. Thus, reducing the delay by 11.3 sec/veh. This will also reduce the queue length from 189m to 37 m in the north bound direction. Table 14 refers to the proposed operational conditions at Kempapura Entrance.

3. As per the inspection report on the improvements required on NH-7 from Hebbal and Bangalore International Airport (BIA), a 3 lane extra limb would be created for traffic from the city to airport with partial modifications to the other limbs of the Hebbal Flyover. This modification will ease the chaos created by the 8 lane traffic from the Elevated road (after the construction of the expressway) squeezing into 6 lanes traffic on the Hebbal Flyover

3.4.2 Kodigehalli Gate Kodigehalli gate is a 3 arm signalized intersection located adjacent to the Godrej Woodsman Estate on Bellary Road.

Issues

1. Longer queues, delay and congestion is a common observation found both during peak and off- peak. This may be due to the construction work for elevated flyover.

2. Despite heavy traffic with high speed there is no exclusive pedestrian signal phasing is provided in the existing signal phasing plan.

3. There are no bus shelters/bus bays, resulting a chaotic movement of pedestrians/commuters to access the buses.

4. Absence of footpath connectivity has forced pedestrian to move on the carriage way.

Figure 32 represents the existing scenario at Kodigehalli Gate.

DULT 41 | P a g e

Traffic Management Study Bellary Road

Figure 32: Existing scenario at Kodigehalli Gate.

Figure 33: Issues at Kodigehalli Gate

Interventions

1. As a part of short term measure, to protect pedestrians from the high speed vehicular traffic at the intersection, a traffic calming measure of provision of curb ramps has been suggested. This will limit vehicular right of way as well as the speed while giving pedestrians a refuge island at the intersection. Curb radii should be designed accordingly to balance the need to accommodate large

DULT 42 | P a g e

Traffic Management Study Bellary Road

vehicle movements and pedestrian safety. Open drains can be covered to increase the extra walkway width.

2. The existing signal doesn’t have an exclusive pedestrian phasing. Considering the width of the carriageway and the future growth of vehicles on Bellary Road, there is a need to provide the pedestrian phase of 15 seconds.

3. The existing bus stops are without shelters on either side of the roadway are located on the main carriageway which creates obstruction in the traffic movement. Thus bus bays on either side with shelter should be relocated on the service lanes to provide a safe and accessible path to the bus stops.

Figure 34 is a pictorial representation of the proposed interventions.

Figure 34: Proposed interventions at Kodigehalli Gate.

3.4.3 Accessibility issues to Bus Stops Higher vehicular speed, grade separators with insufficient pedestrian walkway and insufficient pedestrian signal phase at the intersections are creating an unsafe environment to the pedestrian traffic. Although a couple of grade separators on Bellary road like the Ganganagar, CBI, Hebbal have subway facilities for

DULT 43 | P a g e

Traffic Management Study Bellary Road pedestrian access, grade separators at Anandnagar and bus stops like Mekhri Circle lack pedestrian facilities.

3.4.2.1 Mekhri Circle and Ganganagar Bus Stops Isssues:

The 6-lane Bellary road is divided into 3 lane on either side by high raised median of 2.5m tall .Two bus stops (ie) Mekhri Circle and Ganganagar Bus Stops are located 280m away on either side. However, these two bus stops are not connected or accessible. As per the existing condition, pedestrian and commuters are using a narrow 2m wide median opening adjacent to the Air Force Office to cross the 6 lane Bellary Road. This median opening is connected to a pedestrian traffic signal which is not operational.

Figure 35: Existing scenario at Mekhri Circle

In order to analyse the issues of accessibility, a set of surveys namely, bus stop passenger opinion and count surveys were conducted. The results are as shown Figure 36 below.

DULT 44 | P a g e

Traffic Management Study Bellary Road

Figure 36: Survey Analysis at Mekhri Circle Bus Stop

As per the analysis, the commuter accessing the Mekhri Circle and Ganganagar Bus Stops have expressed their difficulties with respect accessibility bus stop stating problems like no crossing facility (63%), increased speed of vehicles on Bellary Road (13%) and median too high (23%).When questioned about a suitable preference of crossing facility, they suggested that considering the lane width and high vehicular speed, they would prefer a skywalk.

Interventions:

The skywalk of 2m wide connecting the two bus stops (Mekhri Circle and Ganganagar Bus Stops) has been proposed by BBMP. This skywalk will be set up adjacent to the HMT Bhavan. The proposed skywalk will be accessed through a flight of stair with a minimum of two landings. The existing footpath width of 3m may not be feasible to provide ramp access. Elevators will also provide an alternate access to the proposed skywalk. Thus a skywalk with vertical clearance of 5.5m with a slope of 1 in 20 has been designed. The project is in tendering stage. The alignment is as illustrated below in figure 37.

4.5.1.1 Anand Nagar Bus Stops Isssues:

Absence of a Bus shelter, high vehicular speed and no crossing facilities are the issues observed with respect to accessibility at Anand Nagar Bus Stop. At present the pedestrian use the vehicular underpass to access the bus stop. However, the vehicular underpass doesn’t have any space for pedestrian walkway.

In order to identify the need safe pedestrian crossing, a set of surveys at the Anandnagar Bus stop were conducted during the morning peak hour (9:00 to 10:00am). The results are as shown in figure 40 below.

Figure 40: Survey Analysis at Anandnagar Bus Stop

DULT 47 | P a g e

Traffic Management Study Bellary Road

The following results were analysed from the surveys conducted:

1. The number of commuters accessing the bus stop towards BIA is comparitively low when compared to the commuters accessing the bus stop towards Mekhri Circle. 2. The resons given by the commuters when questioned about poor ridership on the bus stop towards BIA were: no dedicated crossing facility,higher speed on the main lane, poor lighting on the service lane,etc. 3. In order of preferance, they suggested grade crossing followed by grade separated facility ie either a skywalk or a subway. Intervension:

Short Term Measure:

In order to provide a safe and convineint pedestrain crossong facility, raised table top crossing adjacent to the bus stop towards Mekhri Circle has been suggested. This facility will also act as a speed breaker and also provide better visibility of the pedestrian to the motorist.

Note: It has been assumed that the vehicular speed will be reduced to 5kmph.

Medium Term Measure:

In future, if either the vehicular volume or the pedestrian volume are likely to increse, a pedestrian signal can replace the table top crossing.
