Making Bicyclists and Pedestrians COUNT in Texas

Making Bicyclists and Pedestrians COUNTThis panel discussion will highlight important uses of bicyclist and pedestrian count data, and will provide an overview of best practices for counting. TTI will also present on emerging technology that uses machine vision to automatically count pedestrians at intersections with traffic signals. TTI recently evaluated the counting accuracy of two traffic signal detection systems with this feature. These systems used cameras to monitor traffic flow at intersections and use algorithms to detect and classify vehicles, pedestrians, and cyclists by travel direction in real-time. This feature not only fills an important pedestrian and cyclist data gap at intersections but also has potential applications to help asses safety metrics such as ‘near misses’ in real-time. Participants will be involved in the 2nd half of session, with chance to ask questions and interact with panel members.

Phil LasleyPhil Lasley is an Assistant Research Scientist with TTI and has worked with bicycle and pedestrian data issues for over 8 years. He has extensive experience with traffic mobility and measurement, data quality assurance/quality control, and mobility policy for the State Legislature. Phil strives to find ways to make data more usable and meaningful in planning and policy.

Bonnie ShermanBonnie Sherman is TxDOT’s Bicycle and Pedestrian Program Manager, working to promote collaborative development of safer, more connected bikeways throughout Texas. In this role, she has assisted in development of a number of statewide efforts, including a bicycle tourism study, bicycle and pedestrian count initiative, and an economic evaluation of bicycling. She has 14 years of experience in active transportation, multimodal, and environmental planning for TxDOT at the local, regional, and state levels. She earned her Masters’ in Community Regional Planning and in Public Affairs as well as a B.S. in Biology from the University of Texas at Austin.

Ana Ramirez Huerta, TxDOT Houston District Bicycle/Pedestrian Coordinator, and Minh Le, TTI Dallas Program Manager/Associate Research Engineer, will also present during this session.
