摘　　要：在分析了基于城市交通信息港的出行前最优路径选择问题的多目标属性的基础上,建立了出行前最优路径选择的多目标规划模型.模型所求得的解是综合最优路径,反映了城市交通出行者信息以及目标需求多样性的特点.设计了基于线性加权法的模型求解算法.通过算例初步验证了模型的合理性和有效性.Based on the analysis of the multiobjective attribute of the optimization route choice problem in urban traffic information center, a multiobjective programming model of route choice before travel is established. The solution of the model is a comprehensive optimization route, which can reflect the diversity feature of information demand and objective demand for urban traveler. The solution algorithm based on linear weighting method is proposed in this paper. The rationality and validity of the model is examined by an example.
