Information Display Company introduces traffic signal timing signs

Information Display Company – a developer and manufacturer of radar speed signs – has launched TrafficFlow Manager, a driver alert display that works with traffic signal timing to help alleviate traffic congestion. When mounted along a route with timed traffic signals, the display informs drivers that the lights are synchronized and lets them know the proper speed that they must maintain in order to avoid having to stop for a red light.

The system consists of a programmable electronic sign that can be connected directly to the signal controller or manually set to display a predetermined speed during specific times of the day or days of the week. An optional GPS timer receiver ensures synchronization between the display and the signal controls. The electronic sign can also be set and controlled remotely from a central office using either a cellular modem or Ethernet connection. It comes with a variety of optional display features and display mountings.

A growing number of cities across the USA are finding the use of timed traffic signals can dramatically improve traffic flow and reduce fuel consumption. The Institute of Traffic Engineers reports that a comprehensive signal timing program can reduce overall travel time by 7-13%, reduce delays by 15-37% and reduce fuel usage by 6-9%. “By synchronizing the lights, we’ve been able to increase safety and reduce driver frustration,” says John Bean, traffic engineer for the City of Longview, Washington. “The key is ensuring that drivers understand that the lights are timed and what speed to travel, in order to take advantage of the arrangement.”
