摘要
The present invention overcomes the inadequacies of prior traffic controls by providing a system for a traffic junction between vehicle paths which includes a first detector for detecting the position of a first vehicle along a first vehicle path. The system includes a dynamic roadway sign for displaying the junction, the vehicle paths and the relative position of the first vehicle to the junction. The dynamic roadway sign is positioned along a second vehicle path, to be visible to any vehicles on the second vehicle path approaching the junction. The dynamic roadway sign is positioned sufficiently prior to the junction to allow sufficient time for vehicles travelling on the second vehicle path to react without abrupt manuevers to avoid collision with the first vehicle at the junction. The dynamic roadway sign would include a graphic display of the junction for the vehicle paths, and icons positioned in sequence in one of the vehicle paths. Each of the icons is illuminated to indicate the presence of a vehicle at a pre-determined position on the vehicle path and its relative position to the junction.
