The San Diego Transportation Management Center
(TMC) is the nerve center for our urban freeway and highway systems. Real time
information is gathered from many sources such as electronic sensors in the pavement,
freeway call boxes, video cameras, 911 calls, officers on patrol, Caltrans highway
crews,ramp meter sensors, earthquake monitors, motorist cellular calls, and
commercial traffic reporters,which is sent to the TMC 24-hours a day, seven days
a week.
Information is received...decisions are made...actions are taken. Dispatch a traffic management team?
Route a Freeway Service Patrol tow truck? Dispatch a hazardous materials clean-up crew? Detour traffic?
Alert motorists via changeable message signs and traffic reports to the media? Close highways for fire,
floods or earthquake damage? Whatever the situation, the TMC provides fast, intelligent and coordinated
responses.
