EFFECT OF BARRIER-LINE LOCATION AT NO-PASSING ZONES

A COMPARATIVE STUDY OF TWO TYPES OF NO-PASSING-ZONE MARKINGS WAS CONDUCTED DURING 1949. A 16.5-MI. SECTION OF 20-FT. BITUMINOUS PAVEMENT ON US 66 IN SOUTHCENTRAL MISSOURI WAS SELECTED. FOR APPROXIMATELY HALF THIS LENGTH, THE STANDARD PAVEMENT MARKING WAS APPLIED, I. E., A BROKEN WHITE REFLECTORIZED CENTERLINE AND, AT THE NO-PASSING ZONES, A SOLID YELLOW REFLECTORIZED BARRIER LINE ADJACENT TO THE CENTER LINE. ON THE REMAINING HALF (MISSOURI SYSTEM) THE YELLOW- REFLECTORIZED BARRIER LINE WAS PAINTED IN THE MIDDLE OF THE DRIVING LANE. THREE GENERAL CLASSES OF INFORMATON WERE OBTAINED. THE FIRST WAS A RECORD OF SPEED AND TRANSVERSE PLACEMENT FOR VEHICLES APPROACHING AND TRAVELING THROUGH A SELECTED SINGLE- DIRECTION ZONE ON EACH TYPE OF MARKING AND THROUGH A TWO-DIRECTION ZONE OF THE MISSOURI DESIGN. SPEED- PLACEMENT DATA WERE RECORDED FOR APPROXIMATELY 11,500 VEHICLES. A RECORD WAS KEPT OF THE START AND COMPLETION POINTS FOR ALL PASSINGS ATTEMPTED OR COMPLETED IN THE DIRECTION CONTROLLED BY THE RESPECTIVE TEST ZONES. THE THIRD CLASS OF DATA RESULTED FROM INTERVIEWING 1,005 DRIVERS AS THEY LEFT THE TEST SECTION TO DETERMINE THEIR REACTIONS TO THE TWO MARKING PLANS. EXCEPT FOR THE DRIVER-INTERVIEW PHASE OF THE STUDY, BOTH DAY AND NIGHT OBSERVATIONS WERE MADE. /AUTHOR/
