Coordination is essential to providing the highest possible quality of service on signalized arterials through movements, and travel time is its most accurate yet most expensive measure. In this seminar, Darcy Bullock will present a methodology for evaluating signal coordination that combines high-resolution signal data with travel time measurement using Bluetooth device MAC-address matching. The Purdue Coordination Diagram is used as a tool for visualizing and quantitatively evaluating signal performance and identifying opportunities for improvements. Bullock will discuss a study in which arterial travel times were measured using MAC-address matching. In the study, intersection and mid-block detecting stations were used to identify, calculate, and implement timing improvements. The presentation will also include a discussion of Bluetooth tracking applications in airport security lines and work-zone origin-destination research.
