Traffic hazard simulator
Abstract
Abstract A SYSTEM FOR TESTING THE DRIVING ABILITY OF AN AUTOMOBILE DRIVER INCLUDES THE PROVISION OF A PLURALITY OF TRAFFIC LANES WITH ASSOCIATED TRAFFIC SIGNAL ROD, ORANGE, AND GREEN LIGHTS. PRESELECTED LIGHTS MAY BE PROGRAMMED TO OPERATE IN RESPONSE TO CLOSING OF AN ACTUATING SWITCH SO THAT THERE IS PROVIDED AN INDICATION AS TO WHICH LANES ARE OPEN OR CLOSED TO TRAFFIC. THE ACTUATING SWITCH IS DISPOSED AT A GIVEN DISTANCE FROM THE ENTRANCE AREAS OF THE LANES AND MAY TAKE THE FORM OF A HOSE TYPE SWITCH SO THAT AN APPROACHING CAR ENERGIZES THE SIGNAL LIGHTS WHEN AT A GIVEN DISTANCE FROM THE LANES. THE DRIVER OF THE CAR MUST THEN MAKE A DECISION AS TO WHICH LANE IS OPEN, IF ANY, WITHIN THE TIME PERIOD DETERMINED BY HIS SPEED AND THE SAID GIVEN DISTANCE.
