Abstract:The design of urban streets and sidewalks must balance the mobility and safety requirements of pedestrians, cyclists, transit users, freight vehicles, and auto drivers. Modern engineers and designers supplement traditional traffic engineering approaches that focus on metrics for automobiles and trucks with more formal consideration of people traveling by foot, bicycle, and bus. The advent of computer vision systems that record counts and pathways of all street and sidewalk users has created new opportunities for data collection, supporting insights that are not possible from the pneumatic tube counters or electromagnetic sensors that are commonly used to measure car and truck traffic. The resulting data can inform street designs that better accommodate all travelers and modes with greater safety. However, computer vision systems using emerging technology must demonstrate their ability to generate consistent, valid, and actionable data before their widespread adoption by urban designers and engineers.
