DESIRABLE PRACTICES

STREET LIGHTING IS SHOWN TO BE AN IMPORTANT SUPPLEMENT TO VEHICLE LIGHTING. REFLECTORIZATION OF HAZARDS AT NIGHT SERVES TO INCREASE THEIR VISIBILITY BY MAKING MORE EFFICIENT USE OF AVAILABLE LIGHT. REFLECTORIZATION IS DESIRABLE FOR PAVEMENT PAINT, LICENSE PLATES, HIGHWAY SAFETY SIGNS, STREET SIGNS, PEDESTRIANS, BICYCLES, SLOW-MOVING VEHICLES, TRUCKS, TRAINS, BUSES, AND AUTOMOBILES. FLUORESCENT MATERIALS ARE EXCELLENT HAZARD MARKERS WHEN VISIBILITY OTHERWISE IS EXTREMELY ADVERSE, NAMELY ON DREARY DAYS AND IN LATE AFTERNOON, EARLY NMORNING, AND DURING TWILIGHT ON CLEAR DAYS. THE AMERICAN SYSTEM OF SIGNS HAS BEEN UNDER STUDY FOR A CONSIDERABLE TIME AND IMPROVEMENTS HAVE BEEN MADE BUT FURTHER IMPROVEMENTS ARE NEEDED. IT IS APPARENT THAT FOR DISTINCTIVENESS THE OCTAGONAL AND CIRCULAR SIGNS ARE THE POOREST, WHILE THE TRIANGULAR AND LONG RECTANGULAR SHAPES ARE THE BEST. THE EUROPEAN PICTORIAL SIGN SYSTEM IS BRIEFLY DESCRIBED. /HSL/
