Traffic Management Center

Overview

This traffic management center oversees a major metropolitan transportation infrastructure on a 24/7 basis. It has various sources of data that need to be monitored and analyzed, including closed-circuit television (CCTV) cameras, traffic and weather sensors, electronic variable message signs (VMS), traffic signals, and ramp meters to monitor and manage traffic flow on streets and freeways. This system allows traffic engineers to collect and monitor realtime traffic conditions from a central location, including visual verification of incidents, and to assist in providing an appropriate response in a timely manner to alleviate traffic congestion to minimize delays to motorists.
