【摘要】 分析某收费站广场的结构和交通流量,确定优化目标的影响因素。选择收费通道的数量、出入口的长度以及排队面积和出入口角为决策变量,建立了工程造价、事故率、吞吐量与决策变量之间的函数关系,确定了入口处和出口区的长度以及排队区的排队长度。建立数学规划模型,得到高速收费站广场设计及收费亭分布最优设计方案。更多还原

【Abstract】 By analyzing the structure and traffic flow of the toll plaza,the influencing factors of the optimization goal are determined. The number of toll channels,the length of entrance and exit,the queue area and the angle of entry and exit are taken as decision variables,and the functional relationships among project cost,accident rate,throughput and decision variables are established. The length of the entrance and exit area and the queue length of the queue area are determined. Then the mathematical programming model is established according to these functions,and the optimal design scheme of high-speed toll station square and toll booth distribution is obtained.更多还原
