What is this indicator?
This indicator measures the City’s progress of the 5-phase signal synchronization project. Signal synchronization involves upgrading traffic signals along a route to keep the signals synchronized. The project looks at the entire Downtown grid in order to: 1) optimize the flow of traffic for both east-west and north-south streets, 2) create timing plans for morning, mid-day and afternoon traffic peaks, 3) update the signal timing to current pedestrian and bicycle standards, and 4) create timing plans for weekends and special events.
How are we doing?
The City commissioned a five-phase signal synchronization project beginning in 2004. The first and second phases covered the Downtown area and were completed by 2008. Phase 3 covered three major arterials, Wilshire Boulevard, Santa Monica Boulevard and Pico Boulevard. Phase 4 covered most of the remainder of the City except for a few outlying areas that will be implemented in a final Phase 5.
Why is it important?
Improving signal synchronization reduces traffic congestion in addition to reducing carbon emissions caused by idling traffic. Updating the timing to pedestrian and bicycle standards will create a safer and more enjoyable environment for pedestrians and cyclists.
