Between the Lines

This article describes the use of radar detection systems as a component in adaptive signal control as opposed to traditional variable traffic control timing and that of inductive loop-based timing schemes. Adaptive traffic control analyzes the entire grid of a municipality's roadways and intersections and continuously optimizes timing in real-time. Radar has an advantage in these types of systems as it can be pervasively and not invasively deployed. Radar also allows for the detection of vehicle speeds within the controlled area automatically. A case example of the use of adaptive signal control in Tyler, Texas is described. The Tyler system uses side-fire radars that are mounted 300-500 feet from intersections where they count, measure, and classify vehicles passing in multiple, bidirectional lanes. No data have been collected concerning the efficacy of this particular deployment.
