Abstract
Abstract The system is adaptable to vehicles having radiant energy proximity detecting or automatic spacing apparatus. A series of fixed radiant energy reflectors is placed along the side of a one-way traffic lane to reflect signals back to a wrong way vehicle and warn or stop the vehicle. A simple addition to the basic proximity detecting apparatus locks the brakes until the vehicle is reversed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
Wrong way traffic control means for a vehicle having a gear shift, brake-actuating means, and radiant energy means for detecting the proximity of a reflective object ahead and controlling the progress of the vehicle in response thereto, including operation of the vehicle brakes, the traffic control means comprising; a plurality of radiant energy reflectors spaced along a one way traffic lane with reflective front surfaces oriented to reflect radiant energy to a wrong way vehicle.
Claim 2
Dependent Claim
75 words
Wrong way traffic control means for a vehicle having a gear shift, brake-actuating means, and radiant energy means for detecting the proximity of a reflective object ahead and controlling the progress of the vehicle in response thereto, including operation of the vehicle brakes, the traffic control means comprising; a plurality of radiant energy reflectors spaced along a one way traffic lane with reflective front surfaces oriented to reflect radiant energy to a wrong way vehicle.
Claim 3
Dependent Claim
13 words
Means according to claim 1, wherein said reflectors have substantially nonreflective rear surfaces.
Claim 4
Dependent Claim
12 words
Means according to claim 1, wherein said reflective front surfaces are nonplanar.
Claim 5
Dependent Claim
25 words
Means according to claim 1, wherein said reflectors are substantially wedge shaped in cross section, with a minimum surface area presented to right way traffic.
Claim 6
Dependent Claim
54 words
Means according to claim 1, wherein said reflectors are spaced to reflect the radiant energy in rapidly successive pulses as the vehicle advances; said traffic control means including pulse-counting means on said vehicle coupled to said radiant energy means to operate said brake actuating means after a predetermined number of pulses of reflected energy.
Claim 7
Dependent Claim
29 words
Means according to claim 5, and including resetting means coupled to said pulse-counting means and being operable by said gear shift to release the brakes upon reversing the vehicle.
