The Ride 2045 Proposed Transit Priority Level

10A-10B: Bus rapid transit

For A2R2, vehicle volumes and speeds were collected using standard pneumatic-tube traffic counters over seven consecutive days, September 17–23, 2025. This provided traffic information for every hour of the day, including five weekdays and two weekend days. U-M and Ann Arbor Public Schools were in session, there was no home football game during the collection period, and the roads were not directly affected by active construction. This provides a broader picture of traffic patterns than counts limited to the morning and afternoon rush hours.

The summary charts show how traffic demand varies throughout the day, allowing us to identify periods when traffic volumes may present challenges to changing the roadway configuration.

• A top identified safety problem area, especially for pedestrians and cyclists.
• Extremely high pedestrian demand tied to hospitals, transit, and the B2B Trail.
• Frequent conflicts with drivers turning right on red not yielding to pedestrians or bicyclists in the crosswalk, wide crossings, speeding, and poor yielding.
• Strong tension between safety needs and concerns about congestion, transit, and emergency access.
• Desire for protected crossings, bike infrastructure, and better operations with desire to not compromise emergency response times.

The City will collaborate with the University of Michigan on designs to improve transit reliability and safety along the corridor. A2R2 findings will help guide that future design work.

Safer crossings for pedestrians and bicyclists

Safer transit facilities

Reduced vehicle speeds

Improved transit service

Current conditions

Glen/Fuller is a major walking and transit corridor linking U-M's Central, Medical, and North campuses. 10A has relatively low operating speeds but very high pedestrian activity, frequent turning conflicts, and recurring transit delay. In 10B, faster traffic reaches about 38 mph on a 35 mph street. Emergency access and hospital operations are important throughout the corridor.

What this design achieves

The design can improve bus reliability, simplify turning movements, and provide safer pedestrian and bicycle crossings while supporting lower and more consistent vehicle speeds. Transit-priority treatments would be developed with U-M and designed to maintain emergency access.
