👉 Who invented traffic signals?


👉 How adaptive traffic signals work?

  • What are adaptive traffic signals? In the simplest sense, adaptive traffic signals adjust the timing of their green light cycles to match current traffic conditions on the ground. They are constantly collecting data about approaching vehicles and creating new timing sequences to match them.

A simultaneous offset is when the signals on an arterial street turn green at the same time. An alternate offset is when a signal turns green at one intersection and the adjacent intersection turns red at that time. A forward offset means the signals turn green in the sequence that follows the direction of travel.
