1. A vehicular radar sensing system, the vehicular radar sensing system comprising:
a radar sensor disposed at a vehicle equipped with the vehicular radar sensing system, the radar sensor having a field of sensing exterior of the vehicle;
wherein the radar sensor comprises a plurality of transmitters that transmit radio signals and a plurality of receivers that receive radio signals, and wherein the received radio signals are transmitted radio signals that are reflected from a radar reflective sign that is present along a road being traveled by the vehicle and in the field of sensing of the radar sensor;
a control having a processor for processing outputs of the receivers;
wherein the radar reflective sign comprises radar reflective information, and wherein the radar reflective information comprises information not visually present on the radar reflective sign, and wherein the information not visually present on the radar reflective sign comprises at least one selected from the group consisting of (i) a distance, (ii) an indication of a pedestrian crossing and (iii) an indication of an emergency shoulder;
wherein the control, responsive to processing of the outputs of the receivers by the processor, determines the radar reflective information;
a display, wherein the display, responsive to the determined radar reflective information, displays the determined radar reflective information for viewing by a driver of the vehicle as the vehicle travels along the road; and
wherein the control, responsive to the determined radar reflective information, transmits the radar reflective information to another vehicle.
