This has led to high traffic congestion in cities like Delhi, Mumbai, Chennai, Kolkata, Pune and Bangalore, whose infrastructure is unable to cope with the rapidly growing vehicle numbers.
The document discusses origin-destination surveys which collect travel data from households including trip origins, destinations, purposes, and modes of transportation. It provides definitions for key terms and describes various survey techniques. Specifically, it discusses home interview surveys where households provide travel diaries and roadside interview surveys where drivers are interviewed at cordon lines. The case study describes an origin-destination survey conducted on a road in Gujarat, India where drivers were interviewed at a survey station to obtain trip origin and destination data.
This document discusses urbanization trends and strategies in major world geographies between 2010 and 2030. It notes that countries like India, China, Mexico, Brazil, and Indonesia will urbanize significantly in this period. National governments represent urban populations and prioritize cities, giving them autonomy. Effective strategies discussed include national policies and financing, demonstration projects, and capacity building. Local governments like mayors are also key decision makers.
Mass transit system refers to public shared transportation, such as trains, buses, ferries etc that can commute a larger number of passengers from origin to destination on a no-reserved basis and in lesser time. It can also be termed as Public Transport.
Mumbai faces significant public transportation problems due to its geography as a group of islands and concentration of commercial activity in the south. Overreliance on private vehicles and lack of infrastructure investment have led to daily traffic jams. Recent government projects like metro lines and monorails aim to improve connectivity, but better public transit options and enforcement of parking rules are still needed to fully address Mumbai's transportation woes.
The National Urban Transport Policy was issued in 2006 by the Ministry of Urban Development to comprehensively improve urban transport services and infrastructure in India. The policy aims to ensure safe, affordable, quick, comfortable, and sustainable access for city residents to jobs, education, and other needs. It focuses on moving people rather than vehicles by providing sustainable mobility and accessibility for all citizens at reasonable cost and time. The policy involves making urban transport a priority in urban planning, allocating more road space to people over vehicles, improving public transport systems, and establishing institutional mechanisms for better coordination of transport planning and management.

The system being planned in Ahmedabad will have most of these components. While planning for
the system, several issues have to be addressed. These may be with regard to the advantages of
inclusion of a component, the way to include the component in terms of its type, magnitude or
quality etc., It is necessary that these issues are addressed both at the general principal level as
well as at the specific design level for Ahmedabad.
As the BRTS concept for Ahmedabad is being developed, for better decisions a wider debate
within the planning and design team as well as with the professional circle is necessary. Wider
information dissemination is also required. To facilitate this, a series of working papers have been
planned.

1. Ahmedabad BRTS Project Overview
1.1. Background
The city of Ahmedabad spread over 400 Sq. km of area, accommodates over five million people.
The main agencies governing the area are the Ahmedabad Municipal Corporation (AMC) and the
Ahmedabad Urban Development Authority (AUDA). There are a host of municipalities and
Village Panchayats within the area of AUDA providing limited urban services. The population
growth in the city has been moderate.
There are about 1.4 million vehicles registered in the city. Of these over 60% are two wheelers.
There are about seventy five thousand three wheelers providing intermediary passenger service
and about two thousand eight-seat ve hicles operating point-to-point services.
The Ahmedabad Municipal Transport Service (AMTS) has been providing public transport service
in the city for over five decades. In the eighties, AMTS had been catering to about 40% of the
trips performed in the city (about six hundred and fifty thousand trips). Today, the service has
shrunk significantly. About 350 buses cater to around two hundred and fifty thousand trips (i.e. 7-
8% of total trips in Ahmedabad). The proportion of Bicycle users in the city is also quite large (i.e.
about three hundred thousand). A quarter of the total trips made in the city are walk trips. As a
result of the above parameters, congestion; pollution and high rates of accidents are becoming
the order of the day.
1.2. The Initiatives
The State and local governments have made significant efforts to ameliorate the situation. These
include:
1. Integrated Transit Plan for Ahmedabad (IPTS) study initiated by Gujarat Infrastructure
Development Board (GIDB)
2. Ahmedabad Metro Feasibility Study initiated by GIDB
3. Suburban Rail Study by AUDA
4. Traffic Management Plans by AMC
In addition the Ahmedabad Municipal Corporation has been making attempts to improve the
existing road conditions through a comprehensive plan. The Ahmedabad Municipal Transport
Service (AMTS) has started operating CNG buses in the city.
1.3. BRTS Initiative
Gujarat Infrastructure Development Board (GIDB), recognizing that no single mode would cater to
the mobility needs of the city and that ‘Bus’ forms the most critical segment of the public transport
system in the city, has decided to develop and implement a ‘Bus Rapid Transit System’ in the
City. GIDB has thereby entrusted the system design task to CEPT University.
The road infrastructure development tasks will be carried out by a Special Purpose Vehicle (SPV)
constituted with the participation of AMC, AUDA and the State Government or directly by AMC
and AUDA (in their respective areas). It is presently envisaged that private operators selected
through competitive bidding will carry out bus operations.
1.4. The Corridors
The patronage towards a public transport system at present is very limited (7-8%). Hence the
prime objective of the initiative at this stage is to develop a market for public transport. As of
now, capacity is a secondary issue. Hence this project focuses on providing a reliable, affordable
and quality service, which is also rapid.
Based on an analysis of the socio-economic factors, travel demand patterns, road network
characteristics, proposed metro plan and existing AMTS route network as the criterions, a

network of roads covering about 155 kilometers in length have been identified for developing the
Bus Rapid Transit System within Ahmedabad. The BRTS network has been prioritized for
implementation giving due consideration to the factors such as travel demand, ease of
implementation and potential of the route to operate as an independent route (operated by the
private operator). Integration with other proposals is taken as a key input.

1.4.1. Phase –I (Year – 2006) Corridor
A circular corridor covering a length of about 60 kms has been identified as main corridor to be
implemented in the year 2006. Development of other corridors has been scheduled in 4 phases.
According to our initial estimates, operation of about 50 buses on the Circular Corridor (for 2006)
with a 6 min frequency would suffice and subsequently the number could be raised to 100 and
200 within two year time period. Fifty buses at 1500 passengers per bus/day would carry a
number totaling to 75000 passengers
Tentatively the composition of the services is expected to be as below:
1. BRTS 2006 (60 kms) – 50, 100 & 200 buses
2. BRTS Mixed Services (90 kms) - 100, 200 & 450 buses
3. AMTS (Balance) - 450,500 & 600 buses

The numbers mentioned above indicate buses at the start of operation, after one year and after a
two-year period. One may introduce Air Conditioned and other improved type of services on
BRTS and other Corridors subsequently.
1.5. Roadway Desi gn
Considering the available road widths following median lanes have been proposed. System
Design aspects in terms of BRTS Corridor (Circular Route) – Design, BRTS Operations Design,
Bus Technology etc., have been dealt with. Initial assessment of the revenue model has been
complete. Detailed project report is being prepared.

2. BRTS Vehicle Technology Choice
Selection of BRT vehicle must be carefully planned as it influences every aspect of transit
performance. BRT Vehicle characteristics affect overall levels of service in terms of speed,
reliability, capacity and cost. Further, vehicle selection should be matched with the characteristics
of the other elements of the system, including running ways, bus station design, service plans,
intelligent transport system (ITS) application and fare collection.
BRTS systems use specialized vehicles to give a distinct appearance and to create an unique
identity. The vehicles are sometimes articulated, environmental friendly and have features, which
increase passenger comfort and convenience. Features adopted also enhance operational
efficiency.
On several dimensions the choice of technology is limited by the governing legislation (Indian
Motor Vehicle Act and Gujarat Motor Vehicle Rules). However, there are certain critical decision
elements influencing the transit operations where choices exist. These include:
• The type of bus (Minibus, Standard Bus, Articulated Bus) determining the capacity of the
system
• Factors such as number of doors, size of doors, location of doors; floor height (Low Floor,
Semi-low Floor and High floor) affecting operating efficiency
• Positioning of the Engine (Front or rear) affecting driver comfort, door space, noise and
vibration.
• Choice of Fuel
• Type and level of access to physically challenged, and
• Aesthetics, Identity and Branding
The choice of vehicle is also going to be determined by the present developments in the
automobile sector. In the country, it is known that truck chassis are being modified for use as
buses. However, some recent developments in terms of developing semi-low floor buses with
aesthetic design are interesting. BRTS development efforts in the country will fasten the process
of innovation in this sector. Needless to mention that BRTS buses used in other parts of the world
are 8-10 times more expensive than Indian buses and therefore choice of imported buses is ruled
out.
The section below discusses the decision elements in terms of nature of decision, its impact on
operations and suggested course of decision for Ahmedabad Rapid Transit (ART). Subsequent
section outlines desirable specifications for the same.
2.1. Decision Elements
The vehicle size is a critical element determining the capacity of BRT. Other factors determining
to system capacity are dwell time, passenger trip-length/turnover, roadway d esign, frequency
etc.,
2.1.1. Travel Demand Assessment and BRTS Solutions
The decision related to system capacity relates to expected demand the system is likely to serve.
Initial travel demand assessment suggests the following requirements.

Given the expected travel demand on each corridor, BRTS solutions are structured. The
following are the typical BRT solutions.
Table 2-2 Typical BRTS Solutions
Transit Passengers per Type of BRT solution
hour per direction
Less than 2,000 Simple bus priority, normally without physical segregation, possible
part-time bus lane.
2,000 to 8,000 Segregated bus way used by direct services reducing the need to
transfer.
8,000 to 12,000 Segregated central busway using direct services with fast boarding
and operating speeds. Good priority at junctions
12,000 to 20,000 Segregated central bus way, with overtaking at stops; possible use
of express and stopping services, some grade separated junctions,
possible shifting to trunk and feeder service, others with good
priority

13. Ahmedabad bus Rapid Transit System (ART) Bus Technology
20,000 to 40,000 Segregated central bus way with overtaking stops, trunk and feeder
system, express and stopping services, priority at intersections,
multiple stopping bays per station.
Over 40,000 This level of demand is very rare on existing bus systems. It is
possible, however, to design a BRT system that would serve up to
even 50,000 passengers per hour and direction. This can be
achieved with full segregation, double bus way, a high proportion of
express services and multiple stops. Consider also spreading the
load through two or more close corridors
Source: Adopted from ITDP with improvisation
From the above it is evident that 8-12 thousand per hour per direction capacity systems are
sufficient for Ahmedabad.
As suggested in the BRT Guide(GTZ), the best vehicle dimension is the one that permits a cost-
effective operation for the given volumes and service frequency. From the point of view of public
transport operational flexibility/efficiency, it is generally suggested that bus fleet with a range of
capacities rather than a single model is recommended.
2.2. Vehicle Characteristics
For selection of BRT vehicles following aspects must be taken into consideration.
1. External Dimension and Capacity
2. Access
- Internal Layout
- Doors & Aisle width
- Floor Height
3. Fuel Choice
4. Vehicle Guidance
5. Aesthetics, Identity and Branding

There are also bi-articulated buses which provide capacities in the range of 240-270 persons.
Box 1 US and European Systems Using Ultra-Modern buses
Fancy buses are only about marketing. Main point is large doors and platform boarding.

It is also observed that there is a growing tendency to adopt ultra-modern looking long articulated
buses for operation. The purpose in these cases is to project image of the bus as an alternative to
rail.

Seating and Standing Area Requirements1
1
A typical transit seat occupies approximately 0.5 m2 (5.4 sq ft, 18 inch width by 27 inch pitch)1. Four
people can stand in one meter square area or approximately 2.7 square feet per person1. At density of three
people per square meter, no standees will be touching another standee anywhere1. Three standees per
square meter shrink dwell time at stop, as well as save time and capital
Government of Gujarat
GIDB AMC AUDA CEPT University

15. Ahmedabad bus Rapid Transit System (ART) Bus Technology
Seating and standing area of BRT vehicle should be a function of the characteristics of the
market being served. If average trip of customers is generally less then 15-20 minutes and
passenger turnover is significantly high. Then more space should be given to standees. In that
case seating space will be same or less than standing area. By that way capacity of the vehicle
may be increased and provide open interior with better circulation characteristics. On BRTS
Corridors in Ahmedabad average trip length ranges between 4 to 6. Hence seating space may be
kept same as standing area.
2.2.2. Access
Doors in terms of number, width and placement, and floor height determine the boarding and
alighting time i.e dwell time at the bus stop.
Doors
With stops every 500 mts it is important that bus dwell time at the bus stops are kept to the
minimum so that overall vehicle utilization is increased and system capacity enhanced. While
dealing with this it has been assumed that the driver will not do ticket issue.
Following are the guidelines recommended as a practice (BT Guide-GTZ).
• One door per 10 ft of bus length should be provided
• Preferably two doors
• In terms of width it is recommended that door should be wider than 75 cm.
• Doors should be positioned to divide BRT vehicles into sections of roughly equal
capacity and circulation distances.
• Position of boarding door should be at center or at the end of rear wheel and
alighting door should come at the front.
• Door width also depends on the fare collection system, off board or on board. If
system is off board fare collection then at a time more passengers will come, for that
larger door width required.
• Door should be less complex and maintenance free with safety.
Door Types: There are five basic types of doors available. They are swing door, Bi-fold door,
Plug door, Pivot door and Sliding door. Of these first three are recommended as the other two are
complex and generally riddled with maintenance problems.
Bi-fold Doors:
• Used where wide opening
is required.
• Ideal for BRT application
• Door panels are one
quarter the width of
opening
Fig 3 Bi-fold door (Tata Star Bus)
Government of Gujarat
GIDB AMC AUDA CEPT University

16. Ahmedabad bus Rapid Transit System (ART) Bus Technology
Swing Doors:
• Simple and easy to deploy
• Safely operated and bus
can be stop close to
station platform edges
Fig 4 Swing door (Van Hool-A330)
Pivot Doors:
• Relatively simple
• Difficult to use for wide
opening because they
intrude into the vehicle
when open
• Creating potential safety
issue.
Fig 5 Pivot door (Thunder Volt Diesel Hybrid-Electric Drive System TB-40HD)
Door Positioning: Door positioning has two dimensions. First decision is with regard to placing
of bus stops in the middle of at the verge. This will determine the positioning of the doors. In case
of Ahmedabad, the decision is to keep the bus stops on the side. (more detailed discussion on
this is presented in working Paper on Bus Stop Design). Hence doors will remain on the left side.
Further placing of the doors in the front, or middle or rear is also an issue. Two doors, one in the
middle and second in the front is suitable way of placing the doors.
CNG Cylinders are placed under the bus. This may create obstruction for placing the door in the
middle.
Please note that some of the pictures below have doors on the right side. These
are shown to illustrate the placing of doors in terms of middle or front or rear and
not left or right side of the bus.
Fig 6 Front and Middle Door

• Not Suitable position of door for
public transport vehicle because
it reduces the seating capacity
of the bus
Aisle Width
Aisle width influences the vehicle capacity, passenger circulation inside the bus and dwell time.
Boarding time increases by 20% when standees are present in the bus 2. Aisle width cannot be
wider than 60 cm if 2+2 perpendicular seats are there in 2.6 m wide bus.
Floor Height
Floor height influences boarding and alighting speed, simplicity and safety. There are three
options available in floor height; High floor, Low floor and Semi-low floor.

High Floor Bus
Floor height is generally near to, 1000 mm to
1050 mm above the pavement. The
advantages are:
- Engine can be accommodated under
the floor along with fuel tank and other
electrical equipments.
- This would increase the onboard
1000 mm
passenger capacity (more space is
available on the floor) 800 mm
- However as boarding and alighting 600 mm
time would be more. 380 mm
0.00 mm
Fig 10 High Floor Bus configuration
Low Floor
Floor height is around 380 – 400 mm above the
pavement.
The basic advantages are:
• Easy and speedy boarding and
alighting.
• Low floor bus can have door behind
the rear axle.
Following are the concerns with the of the low 380 mm
floor buses:
• No space under the floor to
accommodate the engine, fuel tanks
and electrical equipments.
• These will have to be adjusted behind
the bus or else it will take space (4-8
seats area) inside the bus.
• Placing fuel tank or CNG Cylinders on
top of the bus. Refueling would be
difficult and will require higher
specifications for body. Maintenance
and operating cost is normally higher
than the high floor bus.
• Low floor bus’ driveways should be
designed and smooth, without
interruptions because it may harm bus
floor.
Fig 11 Low Floor Bus configuration
Government of Gujarat
GIDB AMC AUDA CEPT University

19. Ahmedabad bus Rapid Transit System (ART) Bus Technology
Semi-Low floor
Semi low floor buses have floor height around
800 – 850 mm above the pavement. Basic
advantage of this type of bus are:
• The fuel tank and electrical equipments
come under the floor, so service
problems would be reduced
• Internal space loss is prevented. Semi-
low floor buses have engine in back
side and have 2 steps inside the bus.
Concerns are:
800 mm
• Semi-low floor bus has steps inside so
600 mm
accidental falls may occur.
• Floor height is higher than low floor so 400 mm
boarding and alighting time increases
0.00 mm
and therefore dwell time affects.
• There is a loss of 2 to 3 seats due to
engine in backside.
Fig 12 Low Floor Bus configuration
In terms of operations and maintenance costs, low floor buses are more expensive. In terms of
capital costs too low floor buses would be higher.
In India, efforts have been made to build semi-low floor buses with slight modification in chassis.
Fig 13 Normal Floor Chassis Fig 14 Low Floor Chassis
Though, high-floor bus can be equipped with bridge, rapidly deployed ramp, door flap or high
platform to reduce conjunction and dwell time, simultaneous operation of the same bus on
exclusive corridors (with high platforms) and on other corridors (without platform) would be
problematic.
However, resale value for vehicle owner would also be an issue if non-standard vehicles were
prescribed.
On the whole semi-low floor bus is most suitable because it gives almost all the benefits of low
floor and high floor bus, in terms of capacity, dwell time, safety and economy.
2.2.3. Fuel type and Propulsion systems
Fuel type and Propulsion systems affects the performance, ride quality, environmental impacts,
overall cost, financial feasibility and service reliability. Local availability of fuel plays major roles in
selection of the type of the fuel. There are different types of fuels like clean diesel; Standard
diesel, Compressed Natural Gas (CNG), Hybrid –electric and Electricity are available which may
use as a fuel of BRT vehicle.
Government of Gujarat

20. Ahmedabad bus Rapid Transit System (ART) Bus Technology
CNG is the best option for internal combustion engines because of the no sulphur and quite
cleanly which emit lower emission. Storage of the CNG is done in on board cylinders. Normally
refueling takes more time in CNG around 15 – 30 minutes. It is near to same as clean diesel as
far as emission level is concern. With high speed compressor the filling time would come down to
5-8 minutes. One of the disadvantages is that CNG vehicle emits greenhouse gases, which are
higher than clean diesel. Although CNG vehicles require different maintenance skill, the same is
not an issue as over 200 buses are already operating in the city.
In Ahmedabad, as per the recommendation of the Supreme Court, AMTS has been operating
CNG buses. Gujarat state also has an advantage of CNG resource state and hence use of CNG
would be an automatic choice for BRTS buses.
Box 2 Features of CNG
CNG reduces:
§ Benzene emissions by 97% compared to diesel and 99% compared to gasoline
§ Nitrogen oxides by 87% compared to diesel and 35-60% compared to gasoline
§ Carbon dioxide by 10% compared to diesel and 25% compared to gasoline
§ Carbon monoxide by 90-97% compared to gasoline
§ Non-methane hydrocarbons by 50-75% compared to gasoline
§ Lead and sulfur emissions by 100% compared to both diesel and gasoline
§ Smoke and particulate matter (PM10) significantly
Advantages of CNG
§ Very easy on the engine, giving longer service life and lower maintenance costs.
§ Reduces the demand for finite petroleum supply
§ Reduces exhaust emission pollution
§ Improves fuel consumption and engine efficiency. When CNG and air in the right proportions
are brought together, they mix thoroughly and rapidly, thereby improving the combustion
efficiency, while the engine stays clean internally
§ Dry gaseous fuel does not dilute the lubricating oil, thus saving on oil filters and oil chargers
Disadvantages of CNG
§ Driving complaints due to loss of power with CNG. Dynamometer tests indicate that CNG-
fuelled vehicles have 10-15% lower power output than petrol engines.
§ Increased exhaust-valve wear in CNG-operated vehicles are anticipated due to the drying
effect of the gaseous fuel
§ Limited service availability
§ High cost of conversion
§ The additional weight of CNG cylinders does pose a problem
(Sources: Natural Gas Vehicle Coalition, EPA Office of Transportation and Air Quality, Natural Gas Vehicle
Association)
Number of Cylinders: Number of CNG Cylinders to be placed on board is an issue. For an
urban bus with less than 300 kms of vehicle utilization, 8 cylinders would be sufficient.

CNG Cylinder position
Fig 15 CNG tank on the top of the bus
CNG cylinders may be placed on the
top of the bus. Though this is a safe
option, bus body structure becomes
very heavy due to cylinder’s load.
Hence the cost of structure will
increase. Further, refueling at height is
difficult. Fuel pipes are at outer surface
of the bus may create safety problems.
Fig 16 CNG tank below the floor bottom
CNG Cylinders are generally placed
under the floor. In this case, refueling
is very easy. Space inside the bus gets
affected slightly. In case of leakage of
gas safety problems may arise. Fuel
pipes are below the bus and hence
safe. At time of accident, cylinders
below the floor are unsafe.
2.2.4. Vehicle Guidance
No-step, no-gap boarding and alighting can make the boarding and alighting faster and easier. It
also help customers carrying packages, having disabilities, and/or with children in strollers to
board and alight from BRT vehicles quickly and comfortably.
This would necessitate following three conditions.
1. Operate low floor buses, or equip high-floor or semi-low floor buses with bridge or rapidly
deployed ramp
2. Create a high platform to the level of step/bus floor, and
3. Provide a vehicle guidance system
There are mechanical, electronic and optical vehicle guidance systems available.
The mechanical guidance system for buses utilize a pre-cast, concrete track with low vertical side
rails or curbs that are contacted by laterally mounted guide wheels that, in turn, are connected to
the vehicle steering system’s idler arm. More recent guidance systems use a light duty track
embedded in the pavement to provide guidance and to serve as an electric return for the vehicle’s
electric power system. The mechanical systems using curbs provide positive guidance and are
safe at relatively high operating speeds (For details see BT Planning Guide)
Advanced electronic technologies (ITS) provide lateral and even longitudinal vehicle guidance.
These systems, as distinct from mechanical guidance technologies, replace physical
infrastructure with inexpensive-to-implement magnetic or optical markers on or in the running
way. Because of their ease of driver-steered vehicle entry and extraction, the operator can take
over at any time and they are compatible with operating plans that feature mixed local and
express operations on a single guide way. There are two types of electronic guidance systems
Government of Gujarat

21
22. Ahmedabad bus Rapid Transit System (ART) Bus Technology
currently in BRT operation: (1) optical, in which a video camera detects the position of a vehicle
relative to painted lines on the pavement and steers via a servo motor in the steering mechanism,
and (2) magnetic, that works essentially the same way as optical, but uses magnets buried in the
pavement. (For details see BT Planning Guide).
Optical systems can also be manually operated. A manual optical system is simply a visual target
for the driver to focus upon while nearing the station.
To prevent collision and damage to the platform rubber padding on the platform sides can be
done.
Feasibility of use of these in our condition needs further exploration.
2.2.5. Aesthetics, Identity and Branding
A unique vehicle identity for a particular BRT service, achieved through paint schemes, colors,
icons and/or design is a necessity. System branding and identity convey important customer
information such as routing and stations served. Vehicle design can complement maps, signs,
and other information sources, further enhancing transit Rider-ship. These aspects are being
dealt with separately.

2.3. Conclusions
Based on the demand, technology assessment and current development in the industry following
conclusions have been arrived at.
a. The moderate demand levels estimated on the corridors can easily be handled by
operating ‘Standard Bus’ with a capacity ranging from 65 to 80 in segregated bus-ways.
From the operational point of view following appear reasonable to adopt.
• Operate standard bus (60-80 person capacity) on BRTS. Make it special with
design and comfort features
• Operate a mixed fleet of standard bus (60-80 person capacity) and mini-bus (35-
40) on other AMTS routes to have flexibility in services.
b. A Semi-low floor and low floor bus would suit the needs in Ahmedabad.
c. Multiple wide doors (center and front) are recommended.
d. At present CNG buses are in operation. Supreme Court directive, Gujarat’s advantage
with CNG leads us to conclusion that CNG should be the fuel for BRTS Bus.
e. A combination of AC and Non-AC buses will have to be operated on the Corridor.
f. It is important to have a classy look that will give the public a good marketing image.
Design aspects need more focus.
g. Specifications, since buses are to be procured by private, need to be such that more than
one manufacturer should be able to supply.
