A STUDY OF THE FEASIBILITY OF USING ROADSIDE RADIO COMMUNICATIONS FOR TRAFFIC CONTROL AND DRIVER INFORMATION- ANNUAL REPORTS NOS. 2 AND 3

A METHOD OF DRIVER-ROADSIDE COMMUNICATION WAS TESTED ON THE ATLANTA FREEWAY SYSTEM DURING DAYTIME AND NIGHTTIME DRIVING ACTIVITIES IN 1964 AND 1965. THE RELATED STUDIES ATTEMPTED TO EVALUATE THE EFFECTIVENESS OF ROADSIDE RADIO COMMUNICATION ON BEHAVIOR OF THE DRIVER AS RELATED TO HIS EXECUTION OF A DIVERGING MANEUVER FROM A FREEWAY TRAFFIC SYSTEM. THEY HY-COM RADIO SYSTEM PROVIDES COMMUNICATIONS FROM THE ROADSIDE TO THE DRIVER AND CONSISTS OF A CAR MOUNTED RECEIVER AND A ROADSIDE TRANSMITTER. VOLUNTEER PARTICIPANTS WERE RANDOMLY ASSIGNED TO VARIOUS TEST CONDITIONS PROVIDING GUIDANCE INFORMATION OF ADVANCE AND EXIT INFORMATION BY HIGHWAY SIGNING, RADIO OR A COMBINATION OF BOTH. DATA ON TRAFFIC CHARACTERISTICS OF THE DRIVER WERE COLLECTED MEANWHILE. TIME-LAPSE MOTION PHOTOGRAPHY, THE BPR TRAFFIC ANALYZER, AND MANUAL RECORDING WERE USED. ANALYSIS OF VARIANCE AND MULTIPLE RANGE TEST TECHNIQUES WERE APPLIED TO DETERMINE DIFFERENCES BETWEEN DRIVER PERFORMANCES UNDER TEST CONDITIONS. RESULTS INDICATE THAT AUDIO MESSAGES WERE AS EFFECTIVE AS VISUAL MESSAGES AND THE PERFORMANCE OF TEST DRIVERS WAS BETTER WITH BOTH AUDIO AND VISUAL MESSAGES. IT IS CONCLUDED THAT A RADIO-SIGNING SYSTEM CAN BE EFFECTIVE.
