Abstract

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.

Biographical Information about Author(s)

Leah Haman is a sophomore civil engineering student from Bismarck, North Dakota. Leah's interest in transportation and safety inspired her to look into opportunities in research and develop her interpersonal connections through the university. In addition, Leah is the president of the Council for Engineering Inclusion and Equity, on the executive board for WAVES, a member of the Society of Women Engineers, and is involved in her sorority.

Carly Schiene is a junior civil engineering major who took an interest in transportation on campus and has been involved in multiple undergraduate research projects for the past year. She also holds various roles for several engineering organizations, including SWE, WAVES, ASCE, and the College of Engineering.

Evan Stock is a senior civil engineering student from Green Bay, Wisconsin who has an interest in transportation. Since his youth, Evan has taken an interest in construction and large-scale infrastructure projects. He currently spends his free time - when not acting as student president of ASCE - browsing maps and staying up-to-date with the latest transportation developments. In addition to engineering, Evan enjoys theology, writing, and people - a combination that inspires him to pursue various career paths.
