Signal Synchronization

LADOT has synchronizing 100% of the traffic signals in the City of Los Angeles to improve traffic flow and minimize congestion.

The final phase (FY 2005 – FY 2013) was made possible through funding provided by state Proposition 1B and secured by Mayor Antonio Villaraigosa.

Our advanced system enables traffic engineers to monitor traffic conditions and make real-time signal timing adjustments to handle emergencies and special events.

Special Events

Special events are activities (e.g. parades, sporting events, concerts, community events, etc.) that create unusual traffic impacts different from the typical day.

There about 2,500 special events held in the City of Los Angeles every year.

LADOT assesses potential traffic impacts for each special event, develops plans to minimize traffic congestion, and posts temporary parking restrictions as well as deploys traffic officers and engineers to manage traffic before, during, and after a special event.

There are three types of special event permits:

Film Permits

Commercial filming in the City of Los Angeles requires a permit issued by Film L.A.

Once permitted, LADOT assists film production by posting temporary parking restrictions, making traffic signal timing modifications, approving temporary lane closures, and providing technical assistance on traffic management plans.

Traffic Signals

Traffic signals are used to improve safety and facilitate the efficient movement of vehicles, cyclists, and pedestrians on city streets when appropriate.

If you believe there is a safety or traffic congestion issue in your neighborhood, you can request an investigation through the myLADOT Service Request system. 

The installation of new or modified traffic signals (e.g. adding a left turn arrow) is determined by LADOT after conducting a traffic engineering assessment. 

Neighborhood Signs

LADOT posts special signs that help residents and visitors identify the geographic boundaries of different neighborhoods and significant places.

The standard neighborhood sign is rectangular and features white letters on a blue background.
