摘　　要：针对实用有效的公交线网优化模型很少的现状,提出了以直达客流密度最大为目标的公交线网优化模型.该模型以换乘次数最少、单位长度运送的客流量最大为优化目标,有效地避免了传统模型仅局限在最短路径上布设线路以及布设的线路偏长等缺点,提高了公交线网的优化质量,使线路与客流走向更加一致.通过实例证明了理论分析和试验结果的有效性.Against the limitation of traditional methods for transit network optimization, a mathematical model is presented aiming to maximize the direct passenger flow density. This model attempts to maximize passenger flow within unit length of transit network and to optimize route directness while maximizing the service cover- age. The problems of traditional methods for transit network optimization are analyzed, such as route design along the shortest path and over - long path. The presented model of direct passenger flow density can avoid these problems. With a numerical test, the effectiveness of the model is verified.
