Neighborhood Transit Street example
In-lane stops keep buses in priority position. Near-side avoids intersection queueing. Can alternate with far-side, pull-out.
Loading zones relieve double parking, provide business access.
Bulbs create space for shelters, reduce crossing distance.
Short signal cycles reduce wait time when bus falls behind progression.
Transit Streets
Textured pavement or vertical separation keep traffic out of transitway
Platforms can be consolidated or separate to fit on narrow ROW
Downtown Transit Street example
Platform-platform crossing serves ped desires lines
Transit Streets
Transit Lanes
Offset Transit Lane • Maintains curbside space for other treatments
• Relatively simple & low-cost• Lacks separation
Stops & Stations
In-Lane Stops • Speeds service by eliminating pull-in and pull-out maneuvers
Stops & Stations
Side-Boarding Islands
• Enables in-lane stops• Balances safe bike and transit
movements• Generally does not require
drainage modifications
Stops & Stations
Shelters
• Place with appropriate clear paths
• Typically 4’ deep (2’ in constrained conditions)
• May face or back up against the road bed
• Enhances comfort and place
Stops & Stations
Accessibility & Universal Design
• Boarding area: 5’ x 8’
• 4’ paths around all elements
• “Three-sense principle”
• Don’t design to minimums!
o Provide adequate capacity
• Color & tactile cues delineate modal edges
• Consistent application

What is the project?• Joint project between Arlington County and
City of Alexandria
• Transit improvements on 4.5‐mile corridor between Pentagon City and Braddock Road Metrorail stations
• First surface transitway of its kind in the Washington region
• Dedicated lanes & exclusive right‐of‐way
• 30 station platforms along corridor
How will it operate?• Bus service operated and monitored by WMATA under
new brand “Metroway” as regional service
• City and County operate and maintain roadways and stations
• Frequent service 7 days a week Every 6 minutes weekday peak in Crystal City
Every 12 minutes weekday off peak
Every 20 minutes late nights and weekends
• Off‐vehicle fare collection and all‐door boarding and alighting
• On‐street and exclusive ROW
On‐street dedicated lane during peak hours
40
How will the network operate from a complete streets perspective?
41
With a dedicated lane during the peak periods, what are the challenges to design and operate the street?
ITE can help!
42
Complete Streets Challenges1. Multi‐jurisdiction Transit Signal Priority2. Cross‐section Design3. Safety: Potential Conflict Points
43
Transitway Operational Challenges
1. Traffic signal operations2. Transit signal priority
• Coordination with WMATA
• Coordination between two jurisdictions
• Technology
3. Right turns vs. transit ops. on exclusive ROW
44
Design & Curbside Management
1. Urban environment / limited ROW2. Cross‐section alternatives
• bike accommodation options• Location of bike lane
3. Curbside management
