What is Bus Rapid Transit (BRT)?

• BRT is high-quality public transit system designed to be fast, reliable, and convenient.

• It operates like rail service on a dedicated transit way, near level boarding, and off-board payment, but with more flexibility and lower cost than rail.

What is Bus Rapid Transit (BRT)?

• Key elements of BRT:− Frequent, efficient service

− Dedicated lanes with signal priority: early green and extended

− Information technology systems

− Rail-style stations

− High-quality buses

− Unique graphics and branding

(Richmond

Highway BRT)

• Route 7 Tysons

to Alexandria

County of Fairfax, Virginia

Richmond Highway BRT Improvements

• Two dedicated BRT lanes in median.

• Roadway widening (no increase in number of through lanes).

• Future connections to walkways, trails, and bicycle facilities.

• Streetscape, including stations, walkways, and medians:− Street furniture, including bikeshare stations

− Pedestrian lighting (facial recognition)

Challenges

• Construction in a built commercial environment

• Posted speed limit:− Clear zone

− Sight distance

• Accommodating the future grid of streets.

• Accommodating future connections to walkways, trails, and bicycle facilities.

• Pedestrian safety and crossing times.

• Interim condition between full build-out and existing land use.

• Storm water management.15 15

County of Fairfax, Virginia

Project Details

• Joint project between Arlington County and City of Alexandria.

• 4.5-mile corridor between Pentagon City and Braddock Road Metrorail stations.

• First surface transitway of its kind in the Washington region.

• Operated by WMATA under new “Metroway” branding.

• City and County maintain roadway and stations.

23

County of Fairfax, Virginia

Project Details

• Dedicated lanes and exclusive right-of-way.

• 30 station platforms.

• Off-vehicle fare collection and all-door boarding.

• Frequent service 7-days a week:

− 6 minutes weekday peak in Crystal City

− 12 minutes weekday off peak

− 20 minutes late nights and weekends

24

County of Fairfax, Virginia

Design Challenges

• How well does the traffic operate in a complete streets environment?

• How well do shared lanes operate during the peak periods?− What are the compromises?

− How do we balance needs?

25

County of Fairfax, Virginia

Complete Streets Challenges

• Multi-jurisdiction Transit Signal Priority: Who governs?

• Cross-section Design: Capacity vs. mobility.

• Operation and safety: Minimizing conflict Points.

26

County of Fairfax, Virginia

Transitway Operational Challenges

• Traffic signal operations

• Transit signal priority:− Coordination with WMATA

− Coordination between two jurisdictions

− Technology

• Right turns vs. transit ops. on exclusive ROW.

27

County of Fairfax, Virginia

Design & Curbside Management

• Built urban environment:− Limited, expensive ROW

• Cross-section alternatives:− Bike accommodation

options

− Location of bike lane

• Curbside management.
