Local Traffic Detectors
Status
Existing
Description
Traffic detectors describe the computerized field control systems located at signalized intersections that run the red–yellow–green lights on traffic signal systems. Most jurisdictions and ODOT use both video and vehicle detection to help with real–time signal timing once their entire signal systems have been upgraded.
This element also includes local traffic controllers.
