Countywide countywide - various locations in macomb county

This $3,171,545.97 formula grant award from the Federal Highway Administration (CFDA 20.205 - Highway Planning and Construction) will fund the installation of Automated Traffic Signal Performance Measures (ATSPM) detection upgrades and Roadside Units (RSUs) at various locations in Macomb County, Michigan. The RSUs will broadcast signal phase and timing information to approaching vehicles, enabling applications such as red light violation warning and priority for special vehicles like transit buses. This project will help advance connected and automated vehicle technology in the region. The grant recipient is the Michigan Department of Transportation, which has demonstrated expertise in executing a wide range of transportation infrastructure projects across the state using federal formula grant funding.

Project description

Automated traffic signal performance measures (ATSPM) detection upgrades. Roadside units (RSU) are supported by fhwa and eligible for federal funding, including cmaq. RSU deployments have been encouraged because they are the critical infrastructure element which helps advance connected and automated vehicle technology. At a signalized intersection, the RSU broadcasts signal phase and timing information to approaching vehicles 10 times a second, enabling existing and future applications in the vehicles on board unit (OBU) such as red light violation warning and priority for special vehicles like transit buses. The RSU and OBU must use the same technology (e.g. dedicated short range communications, dsrc, or cellular vehicle-to-everything, CV2X) for this interface.
