Traffic signals assign the right-of-way to various traffic movements for different time intervals depending on traffic flow levels. Pre-timed signals have preset time intervals for different times of the day, including the morning, noon, and evening peak travel periods.
Traffic actuated signals use detectors located in the pavement on the approaches to traffic signals to monitor and assign the right-of-way on the basis of changing traffic demand. These signals attempt to assign most of the available green time to the heaviest traffic movements. The majority of the signals in Temple Terrace are actuated signals, using detectors.
