Description

The aim of this research is to investigate pedestrian behavior at signalized intersections using state-of-the-art LIDAR sensing technologies and to use this data, along with vehicular data, to develop a more effective multimodal signal control system. In the presentation, the presenters will describe a novel method of collecting pedestrian crossing behaviors at signalized intersection, discuss the findings and implications of data analytics, and introduce a novel approach to dynamic flashing yellow arrow mechanisms to reduce the conflict between left turn vehicles and crossing pedestrians.

Biographical

Dr. Pengfei (Taylor) Li is an assistant professor of Transportation Engineering at the University of Texas at Arlington. He has over 20 years of experiences. Before he was appointed as a professor, he was a traffic engineer, ITS engineer and project manager at various companies and research institutes. His research and professional practices focus on intelligent transportation systems (ITS), smart sensor development, AI and big data analytics. He has built and delivered arterial management solutions and smart sensors for multiple agencies. Dr. Li is active in both research and engineering communities. He led the effort with many professional volunteers in delivering a practitioner-oriented “traffic signal simulation cookbook”, which has been downloaded over 8,500 times. His research has resulted in 70 peer-reviewed and referred papers and one patent. Dr. Li is a professional engineer registered in Alberta, Canada. Sirisha Kothuri, Ph.D. is a senior research associate in the Department of Civil and Environmental Engineering at Portland State University. Dr. Kothuri’s primary research interests are in the areas of multimodal traffic operations, bicycle and pedestrian counting, and safety. Dr. Kothuri is the research co-chair of the Transportation Research Board’s Pedestrians Committee (ANF10) and the Bicycle and Pedestrian Data Subcommittee (ABJ 35(3)) and a member of Traffic Signal Systems committee. Dr. Kothuri received her BCE from Osmania University, India, MSCE from Louisiana State University, Baton Rouge and Ph.D. from Portland State University.
