Frequently Asked Questions:

My neighborhood would like speed humps installed. What are the next steps?

WCRC developed the Neighborhood Traffic Management Program (NTMP) to consistently and effectively evaluate concerns about speeding and cut-through traffic in neighborhoods. The NTMP creates a partnership between residents, WCRC and law enforcement with the primary goal of providing traffic control solutions that are appropriate and acceptable to both WCRC and the community. Please contact the WCRC at (734) 761-1500 to determine if your community qualifies for this program.

The pavement markings on a road need to be redone. What are the next steps?

WCRC reviews all the roadways within our jurisdiction annually and prioritizes the locations based on the budgeted amount.  Please note: standard pavement markings have very little reflectivity when water is on the road and can only be applied during favorable temperatures. To report a pavement marking concern, please visit

A “No Passing Zone” is needed on my road. What are the next steps?

When it comes to changing the passing zones on county roads, WCRC follows the guidelines provided by the Michigan Manual of Uniform Traffic Control Devices (MMUTCD).  The manual provides guidelines for installing passing zones. To learn more about the MMUTCD, click here. The WCRC does not eliminate passing zones for driveways, subdivision streets, or private roads.

I think my road needs a guardrail. How does WCRC determine if one is necessary?

WCRC follows the warrants as described in the American Association of State Highway and Transportation Officials (AASHTO) Roadside Design Guide.

Roadside barrier warrants are a function of the guardrail and the likelihood that the guardrail will be hit.  Protecting a hazard with a guardrail is typically warranted only when the hazard is within the “clear zone” which is described in Roadside Design Guide, and when it has been determined that the result of a vehicle striking the barrier will be less severe than a crash resulting from hitting the unshielded condition.
