NIGHTTIME EFFECTIVENESS OF TWO TYPES OF REFLECTORIZED STOP SIGNS

THIS STUDY PERTAINED TO THE RELATIVE NIGHTTIME EFFECTIVENESS OF TWO TYPES OF STOP SIGNS. ONE OF THE SIGNS WAS CONSTRUCTED OF REFLECTORIZED SHEETING WHILE THE OTHER WAS AN ENAMELED SHEETING WITH 7/8 INCH REFLEX REFLECTOR BUTTONS FOR THE MESSAGE. THE STOPPING EFFECTIVENESS WAS MEASURED IN TERMS OF STOPPING TIME AND STOPPING DISTANCE AS THE DRIVER-VEHICHLE APPROACHED THE DESIGNATED INTERSECTION. THE RESULTS SHOW THAT WHEN THE DRIVER UNEXPECTEDLY CAME UPON THE DESIGNATED INTERSECTION, THERE WAS NO EVIDENCE FAVORING EITHER TYPE OF SIGN AS HAVING MORE STOPPING EFFECTIVENESS THAN THE OTHER. IT WAS ALSO FOUND THAT THE LATERAL DISPLACEMENT OF THE VEHICLE WAS NOT A FUNCTION OF THE TYPE OF SIGN PRESENT. /BPR/
