基于用地生成率和路段流量的OD矩阵估计

针对现有OD矩阵估计方法对用地形态和强度与交通生成的关系考虑不足问题,提出了一种基于用地生成率调查和路段流量调查的现状OD矩阵估计方法.由现状路段流量的调查可以进行OD矩阵的反推;直接调查各类用地生成率,可以得到各小区出发、到达量,通过Frator平衡法对反推所得的OD矩阵进行校正,进而得到现状OD矩阵.

OD Matrix Estimation Based on Trip Generation and Link Flows

In view of the insufficient consideration about the relationship between the shape and intensity of land use and tip generation in the available OD matrix estimation method,an OD matrix estimation method based on the incidence of tip generation investigation and the link flows survey was put forward.An initial OD matrix can be derived from the link flows surveyed.The volume of the trip origin and trip destination of each area can be derived from the incidence of tip generation investigation.The initial OD m...
