RSE Traveler Information Communications Functional Area

Description

'RSE Traveler Information Communications' includes field elements that distribute information to vehicles for in–vehicle display. The information may be provided by a center (e.g., variable information on traffic and road conditions in the vicinity of the field equipment) or it may be determined and output locally (e.g., static sign information and signal phase and timing information). This includes the interface to the center or field equipment that controls the information distribution and the short range communications equipment that provides information to passing vehicles.
