Traffic Behavior at Freeway Bottlenecks
www.purdue.edu/discoverypark/nextrans/research/research_in_progress.php
Record Type: UTC
Freeway congestion results in lost time and resources for travelers. To date, the structure of traffic resulting from bottlenecks and congestion has only been studied with point detectors, which are limited in their scope. This research will use an instrumented probe vehicle to go beyond what is possible with point detectors and assess the events that occur between the point detector stations. The probe vehicle is equipped with positioning sensors (GPS, INS) to track its location and ranging sensors (LIDAR, Radar) to monitor nearby vehicles in the ambient traffic. The probe vehicle collects data throughout the bottleneck region and can observe important signals that may not propagate all the way to the point detectors.
