EVALUATION OF TRAFFIC CONTROL AT HIGHWAY INTERSECTIONS

THE DESIGN AND DEVELOPMENT OF A DIGITAL DELAY DATA RECORDER (D3 RECORDER) AND ITS USE FOR COLLECTING TRAFFIC VOLUME AND DELAY DATA AT INTERSECTIONS ARE DETAILED IN THIS REPORT. EXTENSIVE FIELD MEASUREMENTS OF TRAFFIC CHARACTERISTICS OBSERVED AT 19 LOCATIONS RANGING IN COMPLEXITY FROM LOW-VOLUME INTERSECTIONS OPERATING UNDER STOP SIGN CONTROL TO HIGH-VOLUME SIGNALIZED DIAMOND INTERCHANGES WERE RECORDED FOR SUBSEQUENT ANALYSIS. COMPUTER PROGRAMS USED FOR DATA REDUCTION AND ANALYSIS ARE DESCRIBED AND DOCUMENTED. VOLUME-DELAY RELATIONSHIPS FOR VIRTUALLY ALL TYPES OF STOP SIGN AND SIGNAL CONTROL WERE FORMULATED. CURRENTLY USED WARRANTS FOR SELECTING VARIOUS TYPES OF TRAFFIC CONTROL DEVICES AND PROPOSED WARRANTS FOR USING TRAFFIC ACTUATED SIGNALS WERE EVALUATED. A NUMBER OF RECOMMENDATIONS REGARDING POTENTIAL APPLICATIONS OF THE RECORDING EQUIPMENT AND THE METHODOLOGY DEVELOPED FOR THIS STUDY ARE GIVEN. THE FEASIBILITY OF USING MULTICHANNEL RECORDING DEVICES FOR FIELD STUDIES OF TRAFFIC CHARACTERISTICS HAS BEEN DEMONSTRATED. /AUTHOR/
