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.

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: Computer-implemented predictions of upcoming traffic control signal states or state changes can be used to improve driver convenience, safety, and fuel economy. Such information can be used advantageously by a human operator, or by an autonomous or semi-autonomous vehicle control system. Predictions can be computed with suitable machines installed in a vehicle, in cooperation with a remote back-end server system. The prediction computations in the vehicle may be supported by data communicated to the vehicle computing machinery over various wireless communications, including telecom systems, DSRC, etc.

Abstract: Computer-implemented predictions of upcoming traffic control signal states or state changes can be used to improve convenience, safety, and fuel economy. Such information can be used advantageously by a human operator, or by an autonomous or semi-autonomous vehicle control system. User (for example, driver) requests for a signal change may be implemented in traffic control systems, with all due care. User requests are validated and compared to traffic signal state change predictions. Only when appropriate conditions are met, the user request is used to generate a “synthetic call” to the applicable traffic signal controller (TSC). The new synthetic call substitutes for the usual call signal which arises from a fixed physical hardware detection system such as an inductive loop in the pavement.
