Study On The Setting Conditions And Technical Indexes Of The Composite Interchange Collector-distributor Lane

The rapid development of China’s economy,driven by the expressway and other infrastructure construction investment,the rapid expansion of network scale,the intersection conflict becomes more and more serious,affecting the traffic safety and traffic capacity of the expressway network.As an important hub for connecting roads and road traffic,the problem of intersection is solved.Based on the smaller and smaller space between adjacent interchange,this paper takes the combination of the collector-distributor lane as the research object,researching setting condition and setting up the technical indexes.The composite interchange collector-distributor lanes are used more and more widely,in order to regulate the composite interchange distribution car set,proposed overpass lane definition and composition of the composite,including collector-distributor lane exit section,weaving area,entrance section of the three part.Considering the lane length of weaving area factors,traffic factors,traffic sign information setting rationality and other factors,the evaluation method of service level interleaving area inverse composite interchange collector-distributor lane for maximum traffic volume,as the composite interchange collector-distributor lane Setting conditions.According to the design of vehicle design,service level and capacity and other factors,determine the technical indexes of the composite interchange collector-distributor lane cross section.Combined with the composite interchange shunt affected zone and composite collector-distributor lane overpass lane traffic characteristics,put forward the two reduction composite interchange lane theory calculation model to calculate the collector-distributor lane,the composite interchange single lane and two-lane collector-distributor lane direct deceleration lane length recommended value.Combined with the composite interchange confluence affected zone and composite collector-distributor lane overpass lane traffic operation characteristics of acceleration lane length calculation model,accelerate the use of the composite interchange collector-distributor lane can be inserted into the gap theory,calculate the composite interchange Single collector-distributor lane parallel lane and two-lane collector-distributor direct acceleration lane length recommended value.The research of this paper provides a research method and train of ideas for the later researchers,at the same time provides a sufficient theoretical basis for designers...
