DEMONSTRATION OF A TEST-DRIVER TECHNIQUE TO ASSESS THE EFFECTS OF ROADWAY GEOMETRICS AND DEVELOPMENT ON SPEED SELECTION

THE THREE PRIMARY GOALS ARE: (1) TO DEVELOP A DRIVER- BASED SPEED SELECTION TECHNIQUE, (2) TO APPLY THE TECHNIQUE IN THE ASSESSMENT OF THE EFFECTS OF ROADWAY DEVELOPMENT AND GEOMETRICS ON DRIVER-BASED SPEEDS, AND (3) TO COMPARE THE DRIVER-BASED MODELS WITH NORMAL HIGHWAY USER SPEEDS. THIS WAS ACCOMPLISHED IN FOUR PHASES: METHODOLOGY AND HARDWARE DEVELOPMENT, ESTIMATION OF ROADWAY EFFECTS ON SPEED SELECTION, REPETITION OF PHASE 2 USING DIFFERENT DRIVERS AND A DIFFERENT SECTION OF ROAD, AND RELATING TEST DRIVERS' RESULTS TO SPEED DISTRIBUTIONS OF THE HIGHWAY. THESE EMPIRICAL MODELS, FOR CERTAIN SETS OF ROADWAY CHARACTERISTICS, ARE CAPABLE OF PREDICTING:(1) THE SPEED SELECTION OF THE AVERAGE DRIVER, (2) THE INTERACTION OF THE INDIVIDUAL DRIVER'S SPEED SELECTION AND ROADWAY FACTORS, AND (3) THE VARIATION IN THE DRIVERS' SPEED SELECTION DUE TO INTER-DRIVER AND INTRO- DRIVER VARIABILITY. /FHWA/
