Under certain conditions, traffic signals are installed to delineate right-of-way, improve overall safety, and reduce travel delay at an intersection. The City uses a series of criteria (warrants) from the California Manual for Uniform Traffic control Devices to determine if a traffic signal needs to be installed at an intersection. The installation of a traffic signal is expensive (approximately $250,000 to $300,000) and a significant investment for the City. As a result, the City maintains a priority list of locations and funding is allocated every two years by the City Council in which to build a traffic signal from the list. For a more detailed explanation of the process, please see the New Traffic Signals document.
