A STUDY OF STOP WARNING SYSTEMS

A STUDY OF STOP-WARNING SYSTEMS WAS CONDUCTED INCLUDING' ACCIDENT DATA, FIELD STUIES, AND A SIMULATOR STUDY OF THE VISUAL CONSPECUITY OF THE FLASHER ELEMENTS. THE SIMULATOR STUDY PRODUCED THE MOST VALUABLE INFORMATION, WITH THE ACCIDENT AND FIELD DATA INDICATING SUFFICIENT VALIDITY TO WARRANT THE FOLLOWING CONCLUSION' /1/ THE MOST EFFECTIVE STOP-WARNING SYSTEM OF THOSE INVESTIGATED INVOLVED AN 8-INCH FLASHER MOUNTED ON TOP OF A STOP SIGN ALONG EACH SIDE OF THE ROADWAY, WITH THE TWO FLASHERS SYNCHRONIZED, /2/ THE MOST EFFECTIVE OVERHEAD MOUNTED FLASHER SYSTEM STUDIED INVOLVED FOUR FLASHER WITH PAIRS AT THE SAME HEIGHT OVER THE CENTER OF EACH LANE FLASHER IN SYNCHRONY AND WITH VERTICAL ALTERNATION, AND /3/ USE OF 12- INSTEAD OF 8-INCH FLASHERS INCREASED EFFECTIVENESS BY A FACTOR OF 1.275. ADDITIONAL RESEARCH IS NEEDED TO ESTABLISH THE GENERALITY OF THE PRESENT CONCLUSIONS. /BPR/
