Abstract: Devices, systems, and methods are disclosed for connecting traffic signal control infrastructure, in-service transit vehicles, and back-end computing and service systems, and providing an adaptable user interface, remotely effecting a change on a Portable Electronic Device (PED), verifying location of transit vehicles and tailoring information to the behavior of a transit operator. System determines an “optimal window” for a transit vehicle to travel through a maximum number of consecutive traffic signals during the green vehicular phase. The system determines and sends a recommended speed to traverse the optimal window. In a case where an optimal window is not possible under current circumstances, the system determines and then advises the driver to remain at the current station for a specified dwell time.

Abstract: Traffic signal timing plans are derived from vehicle trajectory or probe data. The probe data is collected and archived in a datastore over a sample time on the order of weeks or longer. Probe data is corrected for clock drift, geo-fence filtered to a selected intersection, and then stop line crossings in the intersection are identified and analyzed along with related data to determine the timing plans and schedule for the intersection. In this way, access to government agency timing plans is obviated so as to save time and expense.
