Evaluation of Alternative Vehicle Detection Systems at Signalized Intersections
Level of Education of Students Involved
The Indiana Department of Transportation (INDOT) currently utilizes traditional inductive loops to detect vehicles at all signalized intersections throughout the state. While functional, inductive loops require specific installation measures, are difficult to maintain, and are not able to be adjusted once placed. This study, sponsored by INDOT, analyzed and evaluated the effectiveness of an alternative vehicle detection method utilizing a pole-mounted radar system. The intersection of LaPorte Avenue at Porters’ Vale Boulevard in Valparaiso Indiana was used for this study. Detection events from the existing, standard inductive loops were compared to the radar system data. Where discrepancies were noted, video footage for the same time interval was used to verify the accuracy of each system. Based on the number of false calls, missed calls, and actuation time lag, the radar system was not found to meet the current INDOT standards of signal detection technologies.
