IMPROVEMENT OF METHODS USED IN THE HIGHWAY PLANNING SURVEYS

IMPROVEMENT OF OBSERVATIONAL TECHNIQUE HAS RESULTED IN (1) THE DEVELOPMENT OF SPECIAL MACHINES FOR RECORDING TRAFFIC COUNTS AND OTHER DATA, PARTICULARLY DATA ON TRAFFIC BEHAVIOR, AND (2) THE APPLICATION OF SCIENTIFIC SAMPLING METHODS TO TRAFFIC COUNTING AND INTERVIEW SURVEYS. INTERVIEWS FROM ONLY ONE PERCENT OF THE VEHICLE OWNERS HAVE PROVIDED SURPRISINGLY RELIABLE INFORMATION ABOUT ROAD USE. ECONOMY HAS LED TO THE USE OF TRAFFIC COUNTS AS SHORT AS FIVE MINUTES ON CITY STREETS. A NEWLY DESIGNED METHOD OF MOVING TRAFFIC ENUMERATION REDUCES THE LENGTH OF THE COUNT AT EACH POINT TO ZERO; IT MAY BE USEFUL IN ARMED RECONNAISSANCE OF HOSTILE TERRITORY FROM AIRPLANES. AN IMPROVED TYPE OF ORIGIN-DESTINATION SURVEY HAS BEEN DESIGNED FOR DETECTING TRAFFIC POTENTIALS THAT DEMAND NEW HIGHWAY FACILITIES AND PREDICTING THE VOLUME OF TRAFFIC THAT WOULD USE A PROPOSED NEW FACILITY. /AUTHOR/
