Abstract:

The primary research objective of this project is to demonstrate the potential capability of emerging LiDAR sensing technologies in identifying and mitigating traffic conflicts (i.e., near-misses) at signalized intersections. The latest LiDAR sensing technologies allow for tracking vehicles and pedestrians (assigning each a unique temporary ID for identification). This capability can be used to mitigate traffic crashes. In this research, the collaborating team between the University of Utah, the University of Texas at Arlington, and the University of Maryland installed the application software developed by UTA and conducted extensive tests in the field, such as the sensors’ latency to identify instantaneous traffic conflicts, the algorithm’s reliability and accuracy, and a demonstration of safety-centric traffic control algorithms The outcome of this research is expected to provide decision support for UDOT to determine its large-scale deployment plan.
