A smart traffic control device transmits information to approaching vehicles regarding its current and future state enabling vehicles to control their speed to avoid arriving at the traffic control device until it permits the passage of traffic, thus avoiding stopping, idling and reaccelerating when reaching the traffic control device. In other embodiments the traffic control device or systems receives information from vehicles, transmitting it to other vehicles.

A method may be implemented to prioritize and analyze data exchanged in a connected vehicle transit network. The method may include receiving, at a roadside unit, vehicle data from a connected vehicle. The method may further include prioritizing the vehicle data received from the connected vehicle based on of urgency, network latency or available computing resources.

An integrated pedestrian access system comprising of wireless push buttons adapted to transmit and receive wireless signals and receivers connected to pedestrian crosswalk signal systems, wherein said one or more receivers are configured to communicate with the wireless push buttons through wireless signals, communicate among the receivers, determine whether source device from which a request for registering a pedestrian signal is received through the said communication is the wireless push button or the receivers, determine status of pedestrian signal based on signals received from the pedestrian signal system, register request for pedestrian crosswalk signal if walk signal of the pedestrian signal is not on in the desired direction as per the status of pedestrian signal and provide acknowledgement corresponding to the status of pedestrian signal through the said source device.

An in-vehicle device for controlling a host vehicle to pass through one or more intersections. The in-vehicle device includes a controller configured to obtain information of an intersection through which one or more vehicles including the host vehicle will pass; identify any of the vehicles that will pass through a same intersection as the intersection through which the host vehicle will pass based on the obtained information; determine a priority level of the host vehicle based on an order of the distances between the intersection and the vehicles sharing the right-of-way of the intersection; judge whether the distance between the host vehicle and the intersection is shorter than or equal to a distance threshold; if that the judgment is positive, the priority level of the host vehicle is enabled; if the judgment is negative, the priority level of the host vehicle is disabled.

An inter-vehicle optical network a plurality of lights, a plurality of optical sensors arranged around the perimeter of the vehicle configured to gather light data regarding a light intensity and gradient of incoming light, a controller communicatively coupled with the plurality of lights and the plurality of optical sensors. The controller configured to receive the light data from the plurality of optical sensors, detect in the light data a second flashing light pattern emitted by an adjacent vehicle with a rhythm, a color, and/or a light intensity, adjust the light level of each light of the plurality of lights based on the light data, adjust the first flashing light pattern in response to the second flashing light pattern, and adjust the first flashing light pattern to synchronize the first flashing light pattern with the second flashing light pattern.
