Abstract
This invention relates to traffic control means for emergency-type vehicles including an on-board plotter screen having a diagram of streets, roads, highways and the like displayed thereon. A light pen is used to draw the preferred route which is then either accepted or rejected in part or as a whole by a computer based on a current street condition program. Once the route has been accepted a traffic signal map program can be activated that will automatically control traffic along the route to the destination of the emergency vehicle.
Claims12
A traffic control for emergency-type vehicle comprising:
- means for selectively plotting a route from the location of the vehicle to a pre-determined destination;
- a street condition program operatively connected to said means for plotting said route whereby the route plotted will automatically be either accepted or rejected by said street condition program;
- once a selected route is accepted by said street condition program, means for automatically signalling emergency warning means at intersections along said accepted route whereby said emergency-type vehicle can reach its said predetermined destination without undue delay.

- a street condition program operatively connected to said means for plotting said route whereby the route plotted will automatically be either accepted or rejected by said street condition program;
- once a route is accepted by said street condition program, a traffic signal control program operatively connected to said means for selectively plotting said route for determining the manner of controlling emergency warning means at intersections along said accepted routes;
- and means for signalling information from said traffic signal control program to said warming means at said intersections whereby said emergency-type vehicle can reach its predetermined destination without undue delay.
