基于超级交通网络的换乘枢纽空间布局优化

利用交通规划理论与超级交通网络,优化城市交通换乘枢纽的数量、空间位置以及规模.依据样本城市的超级交通网络和OD出行矩阵,建立换乘枢纽选址的双层规划模型.上层模型追求交通系统社会效益最大和换乘枢纽建设费用最小,下层模型是超级交通网络上全方式OD交通量的用户平衡分配模型.通过引入改进的禁忌搜索算法实现上下层模型之间的循环反馈.

Optimization of location of transportation terminal with super-network

This paper optimizes the number,location and scale of transportation terminals in a city with traffic planning theories and super traffic network.Based on the super-network and OD trip matrix,a bi-level planning model for locating transportation terminals is developed,where the upper model maximizes social benefit and minimizes the building cost of the terminals,while the lower model assigns the OD of all modes on the super-network with user equilibrium method.To solve the model,an improved Taboo Search algorithm is introduced to realize the iterations between the upper and lower models.
