摘要： Systems and methods for controlling traffic signaling includes a wireless sensor operable to detect and receive wireless signals emitted from a vehicle, an image sensor operable to capture a stream of images of a field of view. A traffic control system is operable to extract geographic positioning information for the vehicle from the wireless signals, track the vehicle's movement using the extracted geographic positioning information, detect and track an object in the stream of images corresponding to the vehicle. The vehicle's geographic movement is further tracked using a pixel location of the object in steam of images and a traffic control action is executed based on the geographic movement to facilitate passage of the at least one vehicle through a monitored traffic control location.

摘要： A method includes positioning one or more roadway sensors and a plurality of a networked array of light emitting diode (LED) raised pavement markers on a road. Sensors proximate the road are associated with a network of road marking controllers that cooperate to control the LEDs as vehicles drive on the road. The LEDs operate as a networked array of roadway lane marking lights. The road marking controller(s) determine a distance between a vehicle on the road and the roadway sensor, determine a dynamic condition associated with the vehicle that changes with respect to time, and lights the plurality of LEDs based at least in part on the distance between the vehicle and the roadway sensor and the dynamic condition associated with the vehicle. Dynamic conditions for operating the LED lighting scheme can include vehicle velocity, a date, a time, a weather condition proximate the vehicle, and other factors.

摘要： Controlling traffic signal preemption includes inputting to a conditional preemption circuit, values of a plurality of incident parameters that include at least a vehicle unit identifier of a vehicle unit and an incident priority that describes an incident. The conditional preemption circuit determines a preemption mode for a vehicle associated with the vehicle unit identifier based on one or more of the plurality of incident parameters. The preemption mode is one of a first mode or a second mode. Traffic signal preemption is enabled for the vehicle unit in response to the conditional preemption circuit determining the first mode. Traffic signal preemption is disabled for the vehicle unit in response to the conditional preemption circuit determining the second mode.

摘要： The present disclosure provides a rapid passing method and device for a target vehicle. The rapid passing method for the target vehicle includes: determining a passing route of the target vehicle according to a place where the target vehicle is located and a destination; acquiring position information of the target vehicle in real time; and controlling lane indicating devices in the passing route to indicate a special-purpose lane used by the target vehicle in the passing route according to the real-time position information and the passing route of the target vehicle, and controlling traffic lights to indicate vehicles disturbing passing of the target vehicle to stop driving when the target vehicle passes through an intersection.

摘要： 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.
