How do you synchronize traffic lights?

Traffic signal coordination is the timing of traffic signals so traffic can travel along a street without stopping at every light. Several factors make trying to coordinate (synchronize) signals difficult. Each street's green indications are referred to as a phase. A simple intersection consists of two phases:

  • Phase one - green for the main street
  • Phase two - green for the cross street

This is called a cycle length. The amount of green each phase is given is based on the amount of traffic on the streets.
