Abstract
Transportation system management requires balancing the needs of many users and multiple transportation modes. Historically, traffic engineers have relied on short-term engineering studies and intuition to manage traffic signal systems. The broad consensus in the traffic engineering community is that real-time performance measures would enable better operations. Motivation and means are presented to provide real-time pedestrian performance measures using existing controller and vehicle detection technology. Applicable pedestrian service models are identified, and procedures for collecting data for pedestrian performance measures are recommended. The resulting pedestrian performance measures can be presented in an easy-to-interpret visual format that provides a valuable tool for assessing and comparing pedestrian service. Pedestrian service may be compared at different crosswalks in the jurisdiction for prioritization purposes, or at the same crosswalk under different conditions. The proposed pedestrian performance measures may be used in conjunction with existing vehicle performance measures, resulting in an integrated approach to assessing the level of service for vehicles and pedestrians under different conditions and for different signal timing plans.
