Information About the Crash
The October, 2025 City Administrator’s report included details of a vehicle/pedestrian crash at the intersection of Glazier and Green. The crash occurred on September 8, 2025.
Note that the pedestrian crash section of this particular administrator’s report is mislabeled as the Bicyclist Crash Report. More noteworthy, though, is the inclusion of two crashes that actually happened at the end of August. The crash reporting process within AAPD can take a few weeks or even longer for serious or complicated crashes. CIAA has recorded several instances in which crashes occurred late in the month and were not ready to be reported publicly when the administrator’s report was published. Adding the late August crashes into the September report is the right way to make sure that the crash information is being shared with the public once it is available.
The UD-10 for the Glazier and Green crash describes how a left turning vehicle struck a pedestrian who was crossing in the crosswalk. The narrative says the driver was turning eastbound from Glazier to Green. This statement is a contradiction since a turn from Glazier to Green would be either northbound or southbound. The diagram shows a left-turning vehicle turning eastbound from Green to Glazier.

The satellite image of this intersection shows some additional details about the unusual configuration at this intersection. The curb lines and lane markings of Green Rd. are not aligned; lanes and curbs south of Glazier are further to the west. Green is also much wider south of the intersection, by more than 40 ft. Lastly, the curbs for both streets have very large radii, which enable faster speeds for turning vehicles. According to Ann Arbor’s speed limit map, the posted speed limit on the portion of Green that the driver was turning from is 35MPH. Glazier, east of Green, has a posted speed limit of 30MPH.

Recommendations:
Evaluation of This Crash By Transportation Experts
The Transportation Engineering staff of the City of Ann Arbor need to evaluate this crash and recommend changes to prevent future incidents like this one. Any serious or fatal crash in the city should get this kind of scrutiny, with a focus on both quick, interim fixes and long term solutions. Their evaluation should include traffic counts of pedestrians and vehicles. Another serious injury crash happened in this crosswalk in 2023; safety at this intersection obviously needs to be improved.
Traffic Calming
The 4-way stop signs at this intersection should mean that any vehicle/pedestrian collision should be happening at the relatively slow speed, as the vehicle should be decelerating and almost stopped or accelerating from a complete stop. But anyone who has watched traffic at a 4 way stop intersection will recognize that many drivers don’t stop completely and instead roll through the intersection. There’s no indication in the report that a rolling stop contributed to this crash or to the severity of this crash. Nonetheless, the wide streets and generous curb radii at this intersection will likely encourage faster speeds. In this crash, the driver was leaving a 35MPH zone (Green north of Glazier) and entering a 30MPH zone. (The posted speed limit is even lower, 25MPH, south and west of this intersection.) Traffic calming like hardened centerlines and slow turn wedges would help to slow drivers going through this intersection and acclimate them for the slower speed limits of the three road segments they might continue on.
Quick Build
A key recommendation in Ann Arbor’s transportation plan is for the city to establish a quick-build program that allows projects to be implemented faster than is possible with conventional roadway construction projects. The plan also recommends establishing “a protocol for responding to fatal and serious injury crashes and evaluating locations for safety enhancements. Use quick-build safety program to make improvements.” There have been two crashes at this intersection in two years and installing some quick-build traffic calming seems like a good way to try and avert another.
