TRANSCRIPT
BRT Design & Realization
BUS RAPID TRANSIT (BRT)• Bus rapid transit (BRT) is a term applied to a variety of public transportation
systems using buses to provide faster, more efficient service than an ordinary bus line.
TransMilenio BRT system in Bogotá, Colombia, holds a record 40,000 passengers per hour.
What is BRT?
Why BRT?
• The goal of these systems is to approach the service quality of rail transit while still enjoying the cost savings and flexibility of bus transit.
Division of Responsibilities
1 •Design
2•Route Planning•Operation & Management
3•Construction & Maintenance
Elements of BRTAn operational plan
Exclusive travel lanes and roadway enhancements
Stations, park & rides
Specialized vehicles
Intelligent transportation systems
Branding
Rationale for choosing side or central bus lanes
Central Bus Lane Curb-Side Bus Lane
1Excessive side-entries forvehicles into service lanes orindividual plots.
Limited access to service lanesor widely spaced entry pointsinto adjoining area.
2Closely placed traffic lights for vehicles may be combined with bus shelters.
Traffic lights at larger intervals.
3Higher volume of two-wheeler and three-wheeler vehicles
Lower volume of two-wheelerand three-wheeler vehicles
EXISTING SITUATION
• Population of Lahore 8 million
• Requirement High level of Transport movement
• Framework of land use Increased trip lengths pattern
• Intensity of development Demands an efficient public transport system
EXISTING SITUATION
• Road network: Suffered with temporary and permanent encroachments
• Traffic condition Disorderly traffic
• Traffic growth Average growth rate of transportation modes Auto rickshaw 32% per annum
Motorcycle 22% per annum Cars 20%per annum
LIMITATION OF EXISTING SYSTEM• Quality of public transport service Blockage of buses in traffic jam
Collisions of buses with small capacity vehicle
Excessive delays
Difficult to adhere specified service schedules
Prevailing less attraction for buses
• Financial Issues
LIMITATION OF EXISTING SYSTEM
• Weaknesses in the regulatory regime
Choosing lucrative routes
Non-lucrative routes without any bus service
• Attractiveness of service
Stretches in headway of buses due to traffic chaos
Diversion of passengers to other modes
What is BRT?
• An efficient rapid transit system using exclusive right of way lanes that match & support the rapidity and performance of metro systems but utilize bus technology which makes it cost effective.
Features
• Exclusive right of way
Features
• Rapid Boarding & alighting
Features
• Pre-board fare collection and fare verification
Features
• Free transfer between lines
Basic BRT Design Types
• BRT Service – This type of BRT consists of a single route
serving stations along a defined corridor. The route might operate in mixed traffic with some use of bus lanes and transit signal priority on a separate facility in a roadway median or unique corridor.
• BRT Facility – This form of BRT consists of purpose-built infrastructure that is intended to be used by multiple routes. The infrastructure is usually a separate busway and can be fully grade separated or can accommodate at-grade intersections.
Service Structure and Route Types
• All-Stops or Mainline BRT Service
• Express or Limited Stop Service
• Routes Using a BRT Facility as Part of Their Route
• Counter-peak Direction Routes
