高速公路通道线路流量均衡化研究
发布时间：2018-08-09 08:02
【摘要】：目前存在较大交通需求的区域之间通常存在多条平行高速公路构成了通道,然而交通量却往往集中于部分线路,造成通道交通设施未充分利用。利用各线路现状交通流量通过"随机用户平衡法"获取OD反推矩阵并以"系统最优分配"得出结果,与现状交通量分布情况进行对比发现差距并不明显。而从交通需求与交通供给角度进一步分析发现流量不均衡现象主要与城市间交通需求、广义费用、高速公路接入口、货运物流布局等因素有关。为此,本文提出了相应的改善措施,以减少未来可能出现的不平衡加剧产生的损失。
[Abstract]:At present, there are usually many parallel highways to form the passage between the regions with large traffic demand. However, the traffic volume is often concentrated on some lines, which results in the underutilization of the traffic facilities of the passage. By using the current traffic flow of each route, the OD backstepping matrix is obtained by "random user balance method" and the result is obtained by "optimal allocation of the system". It is found that the difference is not obvious compared with the distribution of current traffic volume. From the point of view of traffic demand and traffic supply, it is found that the imbalance of traffic flow is mainly related to inter-city traffic demand, generalized cost, expressway entrance, freight logistics layout and so on. Therefore, this paper puts forward the corresponding improvement measures in order to reduce the loss caused by the possible increase of imbalance in the future.
