COMPARISON OF PRESENCE AND PULSE LOOP DETECTORS FOR ACTUATED TRAFFIC SIGNALS

This research effort attempts to compare the effectiveness of various combinations of presence and pulse-type induction loop detectors in reducing intersection delay at a fully-actuated signalized intersection. Various combinations and lengths of detectors were utilized on both the major and minor approaches during a peak and off-peak period. Amounts of intersection delay were recorded by multiple time-lapse cameras operating simultaneously above the intersection area.
