通过O-D调查虽可以取得区域之间的客流量,但因需要投入大量的人力和资金,不可能进行经常性和全覆盖的调查,而且从抽样调查得出分析结果往往有一段时滞。因此,寻求区域之间客流联系的一般规律,利用有限的客流统计资料,借助数学模型来模拟和预测区域间的客流联系成为取得客流分布的一种重要手段。本文通过中国省区之间客流联系和辽宁省内客流联系的分析,对区域客流联系的模型和方法进行了研究。

In this paper, following issues are discussed: division of travel zones, representation of trip distribution, a method of searching shortest path models of travel demand, trip distrihu-tion and trip assignment on transport network. The parameters of zone-zone trip distribution model is calibrated by using observed trip distribution between 20 Railway Bureaus of China and between 13 cities of Liaoning Province, and trip assignment model is examined through analyzing interregional trip distribueion at province level ire China and at city and county level in Liaoning Province.
