How are signals synchronized?
Factors to consider when synchronizing signals are the spacing between signals, the volume and speed of traffic and the cycle length. Signals along main arterials are generally synchronized during heavy traffic times. It is not always possible to synchronize cross traffic. When two-way progression is not possible, the City often uses computerized traffic modeling to find coordinated timing plans that maximize traffic flow. Specific questions about signal progression should be referred to the City's Engineering Department at 214.509.4576.
