DEVELOPMENT OF NEW INTERSECTION STUDY TECHNIQUES - FINAL REPORT

IN ORDER TO STUDY INTERSECTION OPERATION UNDER VARYING CONDITIONS A TECHNIQUE WHICH COMBINES EFFICENT PHOTOGRAPHIC DATA COLLCTION WITH COMPUTER SIMULATION OF INTERSECTION OPERATIONS WAS DEVELOPED. A REVIEW WAS CONDUCTED OF PAST INTERSECTION DATA COLLECTION SYSTEMS TO PROVIDE THE BASIS FOR AN EFFICIENT AND COMPACT MEANS OF EMPLOYING A COMMERCIALLY MADE 35 MM CAMERA. FOLLOWING THIS, DATA WERE COLLECTED ON EACH OF FOUR TYPES OF INTERSECTIONS UNDER STUDY. A MODEL WAS DEVELOPED TO SIMULATE THE TYPES OF INTERSECTIONS. A STUDY WAS PERFORMED, USING THESE TECHNIQUES, TO DETERMINE THE EFFECT OF VARIOUS TRAFFIC CHARACTERISTICS AND THE ADDITION OF A LEFT-TURN CHANNEL UPON VEHICULAR DELAY. THE EXPERIMENTAL DESIGN TECHNIQUE, THE FRACTIONAL FACTORIAL, PROVIDED THE STRATEGY FOR SYSTEMATIC VARIATION OF THE INDEPENDENT VARIABLES, AS WELL AS INFORMATION REGARDING THE EFFECT OF THESE VARIABLES UPON THE DEPENDENT VARIABLE, DELAY PER VEHICLE. A REGRESSION ANALYSIS OF THE EXPERIMENT RESULTS PROVIDES A BASIS FOR PREDICTING DELAY UNDER CERTAIN SPECIFIED CONDITIONS SUCH AS INTERSECTIONS OF TWO AND FOUR LANE ROADWAYS, WITH AND WITHOUT LEFT-TURN CHANNELS.
