VEHICULAR TRAFFIC FLOW THEORY AND TUNNEL TRAFFIC FLOW MEASUREMENTS

VEHICULAR TRAFFIC FLOW HAS BEEN INVESTIGATED THEORETICALLY AND EXPERIMENTALLY IN ORDER THAT PEAK HOUR COLLECTIVE TRAFFIC FLOW DYNAMICS CAN BE UNDERSTOOD AND THAT THE PEAK HOUR FLOW THROUGH THE CALLAHAN TUNNEL CAN BE IMPROVED BY MEANS OF TRAFFIC FLOW CONTROL AND MODIFICATION. TWO THEORETICAL MODELS ARE SUGGESTED, THE FINITE REACTION TIME MODEL AND THE ASYMMETRICAL RESPONSE MODEL, AS PREDICTIVE OF OBSERVED TRAFFIC DENSITY DYNAMICS, WAVE GROWTH, AND ASYMMETRY. EXPERIMENTALLY, A TRAFFIC FLOW PROFILE OF CAPACITIES, VEHICLE SPEEDS, AND TRAFFIC DENSITIES IN THE CALLAHAN TUNNEL HAS BEEN OBTAINED, AND RELATIONSHIPS BETWEEN SLOWDOWN WAVE PHENOMENA AND TRAFFIC FLOW, DETERMINED. BASED ON THESE, IT IS SUGGESTED THAT TRAFFIC FLOW MAY BE IMPROVED WITH TRAFFIC FLOW MODIFICATION PROCEDURES. /NTIS/
