This document discusses recommendations for standardizing urban bus specifications in India. It proposes the following: 1. Uniform internal floor height of 400mm, 650mm, or 900mm without steps to improve accessibility and passenger movement. 2. Door locations and widths of at least 700mm to align with median or side platforms and allow fast boarding and alighting. 3. Technical specifications for improved passenger experience including pneumatic doors, wider gangways, health monitoring systems, and precision docking with stations. 4. Encouragement of local bus body manufacturers and standard testing to ensure quality, affordability and fuel efficiency of buses.

3.  Comfortable & Safe for Passenger
 Accessible for PWD’s
 Better Driving Conditions
 Standardization of common specifications
• Regular and BRTS services
 Technological advancements
 ITS enabled
 Value for money

4. Type Floor Ht. Length Width Total
Capacity
Standard 650 mm 12 m 2.6 m 70
Midi 400/650mm 9 m 2.5 m 40
Mini 900 mm 6 m 2.2 m 22
Standard BRTS 900 mm (max) 12 m 2.6 m 70
Arti-BRTS 900 mm (max) 18 m 2.6 m 110
Bi-Articulated In Process
High end In Process

5.  Pneumatic controlled wider doors
 Wider gangway ≥ 700mm
 Higher acceleration ≥ 0.8m/s/s
 Engine location & fuel: optional
 ROH ≤ 50% of Wheel base
 Approach & departure angle: 8.5˚ & 9˚
 Life cycle: 10 years & 750,000 kms

6. Gangway ROH

8.  Transmission system
 Standards for driver’s area
• Noise
• Vibration and
• Heat

9.  Mandatory door closure for movement of
bus
 Disc brakes
 Design Type approval: Roll over test

10. To be evolved for
650/900mm floor ht ???

11.  Multiplex wiring
 Vehicle Health Monitoring system
 Driver Console
 PIS inside and outside integrated with
audio announcement system
 Camera (inside & rear)

12. 1. Floor inside the bus should be uniform inside
the vehicle without any steps inside vehicle
2. Floor Height of the Vehicle
a) 400, 650 and 900 mm if meets criteria above 1.

Not to Scale

15. 3. Station Location
a) Median Station with platform height to match bus floor
height for BRTS operation
b) Side Station with platform height to match bus floor height
for BRTS operation
3. System may have all Median stations or all Side Stations
or combinations of Median and Side station with
platform height 400 /650 / 900 mm to meet the floor
height of the vehicle.
4. Vehicle door locations and floor height selection will
be based on the design of BRTS element design –
station location, platform height and the local
conditions.

16. Door with steps for end
terminals & open operation
Can also act as emergency
door
Single Wide door in center for
faster dispersal- for operating only
in the BRT corridor
Step-less align with bus stop
platform
 easy access for wheel chair user

17.  Uniform floor height across the length
 Step less movement inside the bus
 Easy & fast dispersal of passenger across the length of
the bus- lesser dwell time

18.  Seats facing each other with common area for circulation
 More space for movement while boarding/alighting
 Plastic molded seats- easy washable with less maintenance

19.  Exclusive area for Wheel Chair User near the door

20.  Precise longitudinal and lateral placement of the bus door
with the station doors is needed for faster, safer and
convenient boarding & alighting of the passengers
• Low Frequency 125KHz RFID Reader at Doors
• LF TAG on the Bus Side Glass near driver
• RF 2.4 GHz wireless Transmitter on the bus driver for Open/Close
• RF 2.4 GHz 4 Door Receiver at the station for door control and communication to
door operator

21. RFID Tag
Precise & safe docking with
the bus stop platform

22.  Limited Bus Manufacturers
 Capacity for maintenance
 Unaffordable AMC
 No standards on fuel efficiency of buses
 ARAI approval is limited to ‘chassis’ only
 No standards to check on performance of AC
buses
 Standardization Station layout wrt door
locations
