摘要
在用户均衡理论的基础上,首先研究超级网络条件下公交车与小汽车交通流量的相互影响,并以公交分担率最大为目标,建立在不同的枢纽选址方案下城市交通网络中公交车流量和小汽车流量分配最优化模型.进而,以公交车与小汽车的出行成本、枢纽建设的土地成本之和作为总成本,以总成本最小为优化目标,建立城市交通枢纽选址优化的双层规划模型.最后,运用案例验证模型,并提出枢纽选址优化的相关建议.
Based on user equilibrium theory,a study was made of the interaction between the traffic flow of cars and buses in super-network,the traffic flows of the two transportation modes were optimized to maximize the bus-sharing ratio.Then,based on the assumption that the total travel cost in urban transportation network consisting of the travel cost of cars and the buses,two-tier location model was established to optimize the total travel cost and land cost.Finally,a case study was made of the two-tier location model and then gives some useful suggestions on optimization location of transportation terminal.
