Bus Rapid Transit System • Floor inside the bus should be uniform inside the vehicle without any steps inside vehicle • Floor Height of the Vehicle • 400, 650 and 900 mm if meets criteria above 1.
Layout DIAGRAM FOR ILLUSTRATION ONLY Not to Scale Drive & Non driver side door for median & side station @ 400/650/900 mm ht to match BRTS platform height Partition between doors for both Driver and Non driver side Tractor Gate Extra optional front Non Driver side gate with steps
Bus Rapid Transit System • Station Location • Median Station with platform height to match bus floor height for BRTS operation • Side Station with platform height to match bus floor height for BRTS operation • 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. • 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.
Doors • 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 • Door with steps for end terminals & open operation • Can also act as emergency door
Floor height • 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
Internal Layout • Seats facing each other with common area for circulation • More space for movement while boarding/alighting • Plastic molded seats- easy washable with less maintenance
Internal Layout • Exclusive area for Wheel Chair User near the door
Vehicle guidance system • 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
Vehicle guidance system RFID Tag Precise & safe docking with the bus stop platform
Issues & Challenges • 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
