The Michigan Department of Transportation, in cooperation with the city of Ann Arbor, will soon install a new High-intensity Activated crossWalK (HAWK) signal at the corner of I-94 Business Loop (Huron Street) and Third/Chapin Street in downtown Ann Arbor.  This will be the first HAWK-style traffic control device on a state trunkline in Michigan.  There are several such signals already in existence throughout the state on local streets, including in Detroit and Oakland County.

A HAWK signal provides a protected pedestrian crossing as a way to increase safety. It is used only for pedestrian crossings. It does not control traffic on side streets.

When you wish to cross the street, you push a button activating the HAWK signal. A flashing yellow light warns drivers approaching the crosswalk of a pedestrian wishing to cross. The flashing yellow light is followed by a solid yellow light telling drivers to prepare to stop.

The signal then changes to a solid red for drivers to stop at the intersection. At this point, you can cross safely. The solid red signal will then convert to a flashing red signal after a predetermined amount of time, telling drivers to proceed through the intersection when it is clear and safe to do so.

The HAWK signal will then go dark. Drivers can continue through the intersection without stopping until the button is again activated.
