turning flow

Improved DIAL s traffic assignment algorithm for directly computation on turning flows;

可直接计算转向流量的改进型DIAL交通分配算法

Two methods for directly calculating turning flows as well as link flows in traffic assignment are proposed,of which the former is based on the turn-path relation and can apply to those traffic assignment algorithms that produce concrete path-structures,while the latter is based on the turn-link relation and is suitable to Dial s algorithm.

提出交通分配中在得到路段流量的同时可直接计算转向流量的两种方法,前者基于转向-路径关系适用于给出具体路径构成的交通分配算法,后者基于转向-路段关系适用于Dial算法。
