Abstract
Traffic signal data is broadcast, for receipt by vehicles traversing the roadways controlled by the traffic signals. If desired, traffic lights are provided with the capability to broadcast their location, status, changing cycles and timing data continuously. A receiving system in a vehicle is configured to receive the traffic signal data and display, to a user of the vehicle, visual display information and/or audible information informing the user of a speed range which, if followed, optimizes the use of the highway and minimizes the number of starts and stops that must be made.
