摘　　要：为了对兰州市现有公交线网进行优化,有效利用现有资源,解决城市交通问题,分析兰州市公共交通存在的问题,依据兰州市公交发展的特点,通过对城市公交线网的优化原则、优化目标的分析,提出公交线网优化的直达乘客密度模型,给出模型的函数表达式及相应约束条件的数学表达式,构造出适合兰州市公交线网优化的模型。In order to optimize the public transportation network in existence, effectively use the traffic source and solve the city traffic problems to Lanzhou, it was analysed the problems which was existed in public traffic of Lanzhou.Tbrough the analysis of principle and objective of optimizing of public transportation network, it was brought forward direct traveler density model and provided the function formula and restriction condition＇s formula by the characteristic of development of Lanzhou public transportation, and constructed opimal model that was suited the public transportation network of Lanzhou.
