| 摘 要： | 为探讨现有公共交通线网结构下BRT线路布设优化问题，对快速公交线路布设的内部条件和外部条件进行了分析；在此基础上依据快速公交的发展特点，以乘客总出行时耗最小和车公里成本投入最小为目标，建立了快速公交布局优化的模型，并且给出了优化目标和相应约束条件的函数表达式。通过事例分析对BRT线路布设优化算法进行说明，从而得知优化模型具有较高的应用价值。

| Abstract: | In order to discuss the optimization of BRT route planning under the existing public transportation network, the paper analyzes interior and exterior conditions of BRT route planning.Based on these conditions,a model is built aiming at the smallest sum of passenger trip time and cost per vehicle kilometer,and a function of optimization aim is given.The optimization model has been illuminated with a case study,which proves the model of practicability. |
