Method and arrangement for controlling vehicular traffic via traffic control devices includes establishing communications between the traffic control devices and vehicles approaching the traffic control devices, and providing information about travel of the vehicle to the traffic control devices to enable the traffic control devices to operate based on the provided information and/or providing information about a status of the traffic control devices to the vehicles to enable the vehicles to operate based on the provided information. The traffic control devices can be constructed to determine whether an approaching vehicle is speeding and if so, direct a communication to the vehicle indicating that the vehicle is speeding. A warning may be provided to an occupant of the vehicle when the vehicle is provided with a communication from a traffic control device indicating that the vehicle is speeding.
