Traffic Signal Vehicle Detection, One Size Does Not Fit All

This study will identify and establish a methodology to determine the most effective and economical type of vehicle detection at a signalized intersection. Since certain types can be more or less efficient depending upon traffic needs, environment, and geometry of the intersection. For many years, Mississippi Department of Transportation's (MDOT’s) standard practice has been the use of inductive wire loops. The life of detection loops are closely tied to the pavement performance, such that as the pavement fails, inductive loops also begin to fail. MDOT has been seeking non-intrusive detection types to replace inductive wire loops. So far MDOT uses several non-intrusive types besides of wire loops traffic signal detectors; however, there is not a defined procedure on how to select the most efficient and cost effective type. The study will provide MDOT with a standardized method for vehicle detection selection, allowing its staff to become more proficient in their effort to improve traffic operations and highway safety.
