Description
Today, the information (signal timings, detector extension, phase sequence, etc.)
to install traffic lights on the street are obtained from traffic software simulations
platforms, meaning that information from simulation is not tested on the field
(intersection where it will be installed) before the installation. Many installed controllers
on the street use time of day (TOD) patterns due to cheaper cost than adaptive traffic
control systems, but that is not the best solution for traffic volume changes that can occur
during the day or even a month. To improve traffic signal operation most of the traffic
signal controllers in the same corridor or zone operate in coordination mode.
Furthermore, phases need to be in coordination to achieve “green wave”. Green wave is
term used when in corridor traffic lights allow continues flow of traffic through
intersections that are coordinated.
