<p>DRIVING TEST RANGE This invention relates to an automobile driving range so laid out that the ability of a driver to carry on normal motor vehicle driving activities can be automatically tested and graded. The driving range contains two-way traffic lanes separated bysensing switches so that a vehicle's presence in the improper lane is readily detected. Each vehicle temporarily has attached to it a radio transmitter having a very limited range and transmitting an identifying signal for the particular vehicle. Buried through-out the range are sensing loops which receive the transmissions from the vehicles and combine the vehicle identification with vehicle operation information being generated at the moment. In those portions of the driving range where driving tracks cross, the intersections can be controlled by stop signs, traffic lights, or any other traffic control devices. Motion detectors at such intersections indicate whether or not a vehicle is in motion at any time. The loop adjacent such intersections receives transmitted information to identify the particular vehicles at the intersection. Similarly, portions of the track are arranged to provide areas in which vehicles may make U-turns, and other areas are provided for parking tests. The entire range has sensing devicesmounted within it which are connected to a data information center where all of the information concerning each individual vehicle is gathered together to produce a final test result for each driver.</p> |
