【摘要】：目前存在較大交通需求的區(qū)域之間通常存在多條平行高速公路構(gòu)成了通道,然而交通量卻往往集中于部分線路,造成通道交通設(shè)施未充分利用。利用各線路現(xiàn)狀交通流量通過"隨機(jī)用戶平衡法"獲取OD反推矩陣并以"系統(tǒng)最優(yōu)分配"得出結(jié)果,與現(xiàn)狀交通量分布情況進(jìn)行對比發(fā)現(xiàn)差距并不明顯。而從交通需求與交通供給角度進(jìn)一步分析發(fā)現(xiàn)流量不均衡現(xiàn)象主要與城市間交通需求、廣義費用、高速公路接入口、貨運物流布局等因素有關(guān)。為此,本文提出了相應(yīng)的改善措施,以減少未來可能出現(xiàn)的不平衡加劇產(chǎn)生的損失。
[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.
