A DEVICE FOR ESTABLISHING A SAFE STOPPING DISTANCE AT NIGHT

A METHOD WAS DEVISED TO ESTABLISH A SAFE STOPPING DISTANCE AT NIGHT AND ITS CONVERSION INTO MILES PER HOUR CONSIDERING THE EXISTING LIGHT CONDITIONS AS DEVISED FOR PURPOSES OF ENFORCEMENT OF THE BASIC SPEED LIMITATION TYPE STATUTE. STOPPING DISTANCES ARE DETERMINED AS IN ACCORDANCE WITH TRAFFIC ENGINEERING. A VISUAL AID DEVICE WAS DEVELOPED TO EXPLAIN THE METHODS OF DEMONSTRATING PERCEPTUAL AND STOPPING DISTANCES AND HOW CHANGES IN ONE AFFECTED THE OTHER. THE APPARATUS CAN BE DESCRIBED AS ONE WHEREBY THE DATA FROM SCIENTIFIC EXPERIMENTS MAY BE REDUCED TO GRAPHIC REPRESENTATION IN SHOWING LAYMEN THE DANGERS OF EXCESSIVE NIGHT DRIVING SPEEDS.
