Road Commission for Oakland County Company

RCOC maintains 2,700 miles of county roads, over 230 miles of state highways and more than 1,500 county, city and state traffic signals in Oakland County. We're also leading the way in developing "smart" traffic signals -- our FAST-TRAC system -- that employ state-of-the-art computer and communications technologies to improve traffic flow, decrease travel time, enhance safety and reduce the vehicle tailpipe emissions that are characteristic of stop-and-go driving.
