Abstract


Mixed traffic intersection has been a major difficulty for China 's urban traffic management , makes our city due to the existence of the phenomenon of mixed traffic intersection running disorder , reduced capacity , delays increased . Non- mixed traffic intersection traffic in order to improve the machine running order , the paper relies on the United States National Science Foundation (NSF) and the Chinese Ministry of Science and Technology , Chinese Academy of Sciences , the National Natural Science Foundation jointly organized the \mixed traffic with graduate students from the University of Tennessee Department of Civil and environmental Engineering Kunming urban signalized intersections do related research . First select the video capture traffic conditions Kunming ring signalized intersection , focusing on non-motor vehicle arrival rate , distance , speed and traffic flow characteristics front indicators were observed , and some indicators the statistical distribution of these through field observation data obtained will be used for modeling below . After an overview of the machine non- conflict and classification established at signalized intersection straight non-motor vehicles turn right on the same vehicle capacity model . Paper modeling first draws on non- signalized intersection gap acceptance theory , observations from the Crosswalk front deduce the non-motor vehicles crossing Crosswalk acceptable gap , combined with the traffic wave theory solving a time share of non- conflict area of non-motor vehicle on the machine , which derived the the Crosswalk capacity conversion coefficient . Then will build model applications the three intersection , articles selected from each of the three intersections an import Road solving the conversion coefficient . Finally, the use of traffic simulation software VISSIM simulation intersection , and the previously established model validation . In view of the results obtained from the modeling and simulation of two ways , between 2 % and 8 % , the gap between the two . Capacity conversion coefficient of Crosswalk solution, proposed a method of calculating the conversion coefficient . Thesis modeling based on actual survey data , mixed line traffic theory and method will have a certain role in promoting .
