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.

• Major barrier to walking and biking, especially across I-94.
• Crossing I-94 safely is the dominant issue.
• The corridor is hostile to people walking and biking, even among those opposed to road diets.
• Strong desire for grade-separated or protected crossing and clearer access management.

Near-term work includes a new mid-block crossing in 6B, filling sidewalk gaps, and coordination with MDOT on a safer non-motorized connection across I-94. For 6B and 6C, a 2027 corridor study will evaluate additional safety improvements, transit reliability, and design options to support future Bus Rapid Transit service.

Safer crossings for pedestrians

Safer bicycle and transit facilities

Reduced vehicle speeds

Improved transit service

Current conditions

State Street serves major employment, shopping, transit, and regional travel. Segment 6A has more flexibility for lane reallocation, while 6B and 6C carry higher traffic volumes and include the difficult I-94 crossing. High speeds, incomplete walking and bicycle connections, and complex intersections create safety concerns, especially near the interchange.

What this design achieves

In 6A, lane reallocation can reduce passing opportunities, support lower speeds, and create space for safer bicycle and transit facilities. In 6B and 6C, near-term improvements focus on safer crossings, continuous walking and bicycling connections, intersection changes, and transit reliability while retaining dual through-lanes.
