Prototype Development for Obtaining Automated Turning Movement Counts for Shared Lanes

This follow-on continuation project will develop and implement a ready-to-commercialize prototype for obtaining automated turning movement counts for shared lanes at a traffic intersection. Stage 1 work is essentially alpha testing involving additional data collection, algorithm improvements, prototype building, and developing interfaces for data retrieval, display, etc. Additional sample trajectory data will be collected at multiple sites with the support of industrial partner, MsSedco, and city transportation agencies (City of Appleton and City of Madison, WI). The performance of the classification algorithm will be improved to overcome the limitations associated with the detection system. In view of the earlier finding that the vehicle detection system undercounts by producing partial trajectories when a significant number of heavy vehicles are present at the intersection, undercounting effects will be analyzed to improve the algorithm performance by relying on a partial trajectory reconstruction or management process. Prototypes will be designed to replace the current approach that relies on a laptop computer for data collection inside the signal cabinet.
