Adaptive Computerized Signalization System – Phase I UPDATE

The Town of Lexington has begun installation of the new Adaptive Computerized Signalization System. Phase I includes 19 traffic signals within the community.

Currently, cameras are being installed on mast arms in downtown Lexington and on traffic signals near Sunset Blvd. /I-20. Additional mast arms and cameras will be installed this winter, with all 19 signals being fully operational by spring 2016.

*Overhead cameras are solely for detecting the presence of vehicles, providing the best distribution of green time based on traffic demand. As the vehicle enters defined areas or “zones” within the camera’s field of view, the camera’s processor detects a change in the “zone”. An output is sent to the traffic signal’s controller (the computerized “brain”) that says a vehicle is requesting green time for its direction. There is no constant surveillance or archiving of these images and are not used for traffic enforcement. The camera view is a fixed focus, fixed location image (there is no zooming or moving the cameras once they are installed). The image is analyzed by the camera processor ONLY for the simple presence of vehicles within defined areas or “zones”.*

  1. This is never go to truly fix the traffic issue in Lexington. More has to be done, including investing in roads!!! The planning of Lexington roads was horrific and unfortunately no one is truly stepping up to address the problem.
