Widening the technology
Roads & Bridges

Noah Wilson Contributing Author
The TMC has at its disposal 31 fiber-optic and dial-up dynamic message signs (DMS), 45 high-technology CCTV cameras, 11 Road Ranger patrols, a severe incident response vehicle and 13 static motorist assistance signs. It also controls 1,325 traffic signals (with emergency vehicle preemption at 298 signalized intersections), as well as 900 school flashers. Those assets enable the TMC to monitor traffic on the major freeways and arterials throughout the county, including I-95, I-595 and I-75. Motorists, though, don’t want to know the specifics; they just want to know that it works.
