Why is this project being done?

Ann Arbor was awarded a federal Safe Streets and Roads for All (SS4A) supplemental action planning grant for project elements: Speed Management, Quick Build and Near Miss Video Analytics system.

Work to be done

The City of Ann Arbor’s FY 2022 demonstration grant will apply treatments through the lense of the Safe System approach adopted by USDOT through the National Roadway Safety Strategy.

The demonstration project will advance the City and USDOT’s shared goals to reduce and eventually eliminate deaths and serious injuries from roadway crashes.

Through this grant, the City of Ann Arbor will design and deploy systemic safety countermeasures to inform the City’s safety action plan across 17 miles of roadways, including 13 miles of the City’s high injury network.

The grant cost-effectively delivers on three strategies included in Ann Arbor’s Transportation Master Plan: High Crash Locations, Addressing Dangerous Behaviors, and Quick Build Treatments.

The scope of improvements includes FHWA Proven Safety Countermeasures and systemic treatments consistent with national best practices and those recently deployed and tested by the City. These include:

• Pavement markings, signage, and temporary delineators that encourage compliance with existing posted speed limits, including predictable, consistent lane widths appropriate to Ann Arbor’s urban context.
• Pavement markings that make all users more visible and aware of one another, particularly in high-conflict areas like major intersections, including conflict markings, guide markings, and high visibility crosswalks.
• Use of pavement markings and temporary delineators to indicate where users should travel including hardened centerlines to prevent unsafe turns that may impact people crossing and waiting vehicles
• Tightening curb radii to slow turns and reduce crossing distances for pedestrians through paint-and-post bump outs.
• The scope of improvements does not include any road diets or changes to capacity at intersections.

Near Miss Video Analytics System – utilizing existing Gridsmart cameras at 61 city intersections to understand factors that lead to crashes and “near miss” events. The City will be partnering with University of Michigan Transportation Research Institute to complete this work.
