Department of Public Works
County of Los Angeles Traffic Management Center (TMC)

Welcome to the Intelligent Transportation System Site

To help in the on-going effort to improve mobility on our congested local highways and streets, the Department of Public Works (DPW) began administering numerous multi-jurisdictional Intelligent Transportation Systems (ITS) projects.

The technologies deployed under these ITS projects will enable DPW staff to monitor and control traffic signal operations from a remote location on a real time basis. Staff will receive immediate notification of signal malfunctions resulting in more efficient maintenance responses. Using roadway sensors and closed circuit television cameras to monitor traffic conditions, staff will be able to better manage congestion caused by incidents and special events. These ITS technologies also include providing motorists with both pre-trip and en route information on roadway traffic conditions through devices such as cell phones, Changeable Message Signs, and the Internet. All of these functions are coordinated through the County of Los Angeles Traffic Management Center (TMC) at DPW's Headquarters in Alhambra, California.

Below are links to the key systems and projects installed and being deployed from the TMC.
