Detector-Free Method of Determining Profiles of Vehicle Arrivals at Signalized Intersections
Researchers at Purdue University have developed a technology that replaces the use of a vehicle detector with analysis of vehicle trajectories obtained by using GPS-enabled mobile devices. Analysis of the trajectories determines when the represented vehicle crosses a virtual detection line, which allows for the sampling of vehicle arrivals over time. This method works with very low levels of market penetration, such as 1 percent or less. This technology allows for the implementation of responsive and adaptive control methods in traffic signal systems that currently lack a detection system. It will work with future connected vehicles as they increase their market penetration.
