1 TECHNOLOGIES FOR AUTOMATED PEDESTRIAN DETECTION AT SIGNALIZED INTERSECTIONS

The safe accommodation of vulnerable road users, as well as their equitable access to the transportation system, are fast becoming two of the most critical issues facing North American cities today. As the population ages, impairments to mobility, vision and physical strength are becoming prevalent. This can sometimes translate into accessibility limitations, resulting in hazardous situations for the users of the system. Traffic signals are a component of the transportation system which is used by all kinds of users. While drivers of motorized vehicles do not need to take any action to be detected by a signal, pedestrians must use pushbuttons for detection at these locations. This requirement has resulted in major concerns in Winnipeg and other North American cities, particularly in addressing the equitable treatment of different users of the transportation system, and its consequent impact on road safety. The purpose of this environmental scan is to obtain an understanding of current technologies used for the automated detection of pedestrians at signalized intersections. This is accomplished through a comprehensive literature review and jurisdictional survey regarding this issue
