FINAL REPORT-STATISTICAL STUDIES IN TRAFFIC FLOW PROBLEMS, VOLUMES I AND II

THE 14 REPORTS RELATE TO SIX AREAS: URBAN INTERACTION ANALYSIS, ESTIMATION OF PARAMETERS OF VELOCITY DISTRIBUTION, TRAFFIC FLOW MODELS, HIGHWAY AUTOMATION SYSTEMS, PLATOON AND CARAVAN MODELS AND TRAFFIC CONGESTION MODELS. IN URBAN INTERSECTION ANALYSIS, TECHNICAL REPORTS NO. 7, 8, 12 AND 14 ON THE VARIABLE CYCLE TRAFFIC SIGNAL AND OPTIMUM INTERSECTION CONTROL CONSIDER INPUT PROCESSES THAT ARE OF A DEPENDENT TYPE INCLUDING MARKOV CHAINS AND MARTINGALES. SPECIAL CASES ARE CONSIDERED INVOLVING IPTIMIZATION OF PARAMETERS USING THE CRITERION OF MINIMUM TOTAL DELAY PER CYCLE. TECHNICAL REPORTS 9, 13, AND 15 CONSIDER THE GAMMA (OR ERLAND) FAMILY OF DISTRIBUTIONS USING BAYES, MAXIMUM-LIKELIHOOD AND SERIES EXPANSION METHODS OF ESTIMATION AS WELL AS MAKING COMPARISONS TO THEIR UTILITY. TECHNICAL REPORTS 10 AND 17 REPRESENT RESEARCH IN THE TRAFFIC FLOW AREA CONSIDERING RELATIONSHIPS BETWEEN THE CONTINUUM AND CAR-FOLLOWING MODELS AS WELL AS APPLYING BIRTH-DEATH AND DIFFUSION PROCESSES. TECHNICAL REPORT 11, PREPARED FOR HIGHWAY AUTOMATION SYSTEMS, DEVELOPS A DECISION RULE AND TABLES FOR SELECTING ALTERNATIVE HIGHWAY AUTOMATION SCHEMES. IN PLATOON AND CARAVAN MODELS, TECHNICAL REPORTS 18 AND 20 CONSIDER A SINGLE LAND ROAD WITH A NO PASSING SITUATION INVOLVING INTER-RECORD TIMES. THE TRAFFIC CONGESTION AREA CONTAINS TECHNICAL REPORTS 16 AND 19, THE FIRST OF WHICH DISCUSSES POINT PROCESSES AND TANDEM QUEUES WHILE INTRODUCING A MODEL THAT TREATS TRAFFIC AS A STATIONARY SPATIAL POINT PROCESS CONSISTING OF THE SUPERPOSITION OF TWO INDEPENDANT PROCESSES. REPORT 19 INVESTIGATES BOTTLENECKS ON A SINGLE LANE OF ROAD TAKING INTO ACCOUNT DISCRETE EFFECTIVE LENGTHS OF CARS AND CAR-FOLLOWING BEHAVIOR. /FHWA/
