Using Probe Vehicle Data to Understand Bottlenecks and Congestion
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 project proposes the use of an instrumented probe vehicle, equipped with both positioning sensors and ranging sensors, to collect data along I-71 in Columbus, Ohio. Research findings will lead to more accurate traffic flow models, impacting safety and fuel efficiency in heavily traveled areas.
