Enhancing Pedestrian Accessibility Through Intelligent Traffic Signal Optimization

Description

16. Abstract
As cities and communities nationwide seek to develop Complete Streets that foster livability and accommodate all modes, signal timing control
strategies that include pedestrians in the operational decision process are gaining importance. This research tested several efficiency-focused
pedestrian treatments Ð coordination, actuated-coordination, free operation, short cycle lengths Ð and safety-focused treatment including leading
pedestrian intervals and Barnes Dance. Using a software-in-the-loop simulation, the operational impacts of these treatments on all users (vehicles,
heavy vehicles, bicyclists and pedestrians) at an intersection were evaluated. Results showed that among the efficiency-based treatments, free
operation was most beneficial for reducing minor-street pedestrian delays. Both safety treatments increased major-street vehicle delays.
