摘要
交通网络配流问题是将实测或预测的交通分布量按照特定的出行规则分配加载至具体的道路网中,并根据相应算法求解得到各道路路段与交叉口节点的交通流量。首先介绍了有关交通配流的基本方法及性质,总结了常用的平衡及非平衡交通配流模型。考虑到平衡模型求解困难且算法运算时间长,将非平衡配流模型解法运用到平衡配流中去,以寻求复杂平衡问题的高效解法。
The traffic network distribution problem is that the OD traffic volume that has been predicted(measured) is allocated to each road in the road network according to a certain rule according to actual conditions,and the traffic flow on each road and node is obtained. This paper first introduces the basic methods and properties of traffic distribution,and summarizes the commonly used equilibrium and non-equilibrium traffic distribution models. Considering that the equilibrium model is difficult to solve and the algorithm operation time is long,this paper attempts to apply the non-equilibrium flow model solution to the balanced distribution flow and seek a solution to the equilibrium problem.
