METHODOLOGY FOR TRAFFIC FLOW EFFICIENCY

THIS REPORT CONSISTS OF THIRTEEN TECHNICAL PAPERS THAT ARE MAINLY CONCERNED WITH TRAFFIC PROBLEMS ON FREEWAYS, SIMULATION VALIDATION PROCEDURES AND EXTENSIONS OF QUEUEING THEORY FOR GENERAL INTERARRIVAL AND SERVICE TIME DISTRIBUTIONS. REPORTS 1, 2, 3, 4, 5, 12 DEVELOP GENERAL QUEUING THEORY FOR APPLICATION TO MERGING CONTROL PROBLEMS AND TO ANSWER QUESTIONS OF PRIORITY LANES. REPORT 6 TREATS THE PROBLEM OF ON-LINE PREDICTION OF TRAFFIC CONGESTION INVOLVING SELECTION OF APPROPRIATE DEPENDENT AND INDEPENDENT VARIABLES, SPECIFICATION OF THE MODEL AND PROPERTIES OF THE ESTIMATES FOR THE PARAMETERS. REPORTS 7, 8 AND 9 ARE CONCERNED WITH STOCHASTIC MODELS OF ENVIRONMENTAL IMPACTS OF HIGHWAY TRAFFIC IN WHICH A CLOSED FORM EXPRESSION IS OBTAINED FOR THE NOISE VARIABILITY AND THE FIRST TWO MOMENTS ARE GIVEN FOR A MIXTURE OF CARS AND TRUCKS ASSUMING EXPONENTIAL HEADWAYS. LATER, REPORT 9 DEVELOPS AN AIR POLLUTION MODEL FOR A SINGLE-LANE HIGHWAY AND A NUMERICAL EXAMPLE IS PROVIDED FOR A RUSH HOUR TRAFFIC SITUATION YIELDING POLLUTANT EMISSION-RATE MOMENTS. REPORT 10 STUDIES THE VEHICLE QUEUE LENGTH IN A NETWORK OF CLOSELY SPACED SIGNALS WHILE REPORT 13 IS A COMPARISON SURVEY OF STOCHASTIC MODELS FOR MUTLILANE FREEWAY TRAFFIC. REPORT 11 DEVELOPS USEFUL STATISTICAL TESTS IN VALIDATION PROCEDURES FOR NETWORK SIMULATION MODELS. /NTIS/
