WaySync-M, short for WaySync-Mobile, is a mobile tool designed for real-time diagnosis and performance evaluation of traffic signal timing plans. Users can create virtual signal controllers on their mobile devices, replicating field timing plans. With advanced features like geo-referencing and dynamic time-space diagrams, it simplifies identifying issues in coordinated signals such as phase early return, clock drifting, and incorrect offset inputs. This tool serves as a valuable supplement for optimizing coordinated traffic signals.

WaySync-M offers a dynamic time-space diagram with integrated vehicular trajectory for precise diagnosis and performance assessment of coordinated traffic signals. Key features include real-time display of Time-Space Diagram (TSD) and traffic signal timing on a map, bandwidth and attainability checks when editing timing, GPS track and video recording for traffic performance enhancement, and support for non-common cycles optimization.
