OD交通量的估计方法

OD调查结果是城市交通规划和交通控制、管理的基础数据,进行OD调查需要投入较大的人力、财力、物力,工程量相当大。与此相比,路段交通量的调查相对容易,便于操作,并且有相当一部分路段设有常年观测站,可进行全年观测,能掌握路段交通量的动态变化情况。路段交通是由各个交通小区之间的交通分布在径路选择上累加而成的,二者存在着较大的联系。从介入机会模型和路段交通量推出两者之间的关系,并由此推算出OD调查表。

OD volume of traffic estimate method

The OD result of investigation is the basic data of the urban traffic planning,control and management and the project needs more manpower,financial resource and physical resource.Compared with this,the road section volume of traffic investigations is more easy,more advantageous to operate,and more road sections have been equipped with the observation station year by year.It may carry on the whole year to observe,and can grasp the dynamic change situation of the road section volume of traffic.The road section traffic from the various transportation plot in the distribution of traffic between the choice of approach from the cumulation that there are more links.It promotes the relationship between the two from the involvement opportunity model and the road section volume of traffic,thus calculating the OD examination table.
