Intersection Monitoring Using Computer Vision Techniques for Capacity, Delay, and Safety Analysis
Brendan Morris, Mohammad Shokrolah Shirazi · 2017
In this chapter, intersection analysis including capacity, delay, and safety is presented using computer vision techniques. An intersection appropriate vision-based tracking system is presented, which aims to provide long-term tracks of road users provide classification (i.e., vehicle and pedestrian) and handle the partial occlusion problem. Road trajectories are further investigated and modeled to provide road user count, vehicle queue length, and safety analysis including accidents and conflicts. Since accidents are infrequent events, surrogate safety measurements were leveraged to provide conflict severity measures at intersection facilities. Finally, technology-enhanced safety for all participants, including vehicles, drivers, and pedestrians, through communication and sharing of dynamic profiles between infrastructure and cooperative vehicles is highlighted.
