Why is this project being done?

In 2021, the City of Ann Arbor adopted the Moving Together Towards Vision Zero (MTTVZ) Comprehensive Transportation Plan, which is organized around achieving two big goals:

• Vision Zero – No one dies or is seriously injured on Ann Arbor’s streets
• Carbon Neutrality – through reduced car dependence and electrification

In pursuit of these goals, the City recognizes that:

• Vehicle speed is a major factor for how likely and how severe a traffic crash will be,
• People walking and cycling make up an outsize proportion of severe crashes, and
• People need to feel confident and capable to move outside of a large vehicle

The MTTVZ plan recognizes that a disproportionate number severe crashes occur on higher speed, wide arterial streets and intersections. As a step to direct attention and resources to the high crash severity streets, the City published a Speed Management Program and Toolbox, identifying a set of tools for street designs that produce lowered vehicle speeds and increased driver attention.

The A2R2 aims to improve safety, reduce speeds, and enhance multimodal connectivity along arterial streets. This project purpose is aligned with the broader MTTVZ goals through strategies such as redesigned intersections, quick-build treatments, and community engagement.

Work to be done

The Ann Arbor Roadway Rightsizing (A2R2) project will evaluate the feasibility of “rightsizing” arterial streets. Rightsizing refers to re-purposing excess motor vehicle traffic lanes for other uses such as dedicated transit lanes, separated bike lanes, or additional sidewalk and amenity space.

Roadway Rightsizing projects can reduce speeds, better organize traffic, address systemic safety issues, and incorporate planned transit and bicycle infrastructure throughout the City.

This project will result in conceptual designs for the ten corridors that are responsive to the MTTVZ and A2ZERO plan.

Funding Source

Council-directed use of the city's major streets Act 51 resources.

This project will result in conceptual designs for ten corridors that will apply proven safety countermeasures to improve safety, reduce vehicle speeds, and enhance multimodal connectivity along arterial streets.
