Bus Rapid Transit (BRT) Design

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
