项目摘要
The current discrete transportation network models, which determine traffic flow on every link of a transportation network, are rather inapplicable to dense and large urban road network because of the huge amount of computational work involved. In this study we adopt a continuous approach to approximate a highly dense network and consider the traffic assignment model based on the assumption of continuous traffic flow distribution over the urban area. Two types of models are presented containing both theoretical and applied analysis of the continuous approach.First, a theoretical model, complete with an efficient computational algorithm, is constructed by using constrained variational theory and FEM technology. Distinguished from the previous approaches, this model deals with the user-equilibrium assignment with a single trip origin and continuously distributed trip destinations.With the intention of complementing the theoretical approach, a continuum approximation model is also proposed for computing the generalized traffic flow distribution over the urban area. This model is demonstrated to be efficient for the large-scale traffic assignment.The continuum models presented in this study are numerically tested with hypothetical data. The computational results coincide with the expected behavior of the proposed models.
目前的离散交通网络模型主要是确定交通网络中各个环节的交通流量,由于计算量大,不适用于密集的大型城市道路网络。在这项研究中,我们采用连续的方法来近似一个高密度的网络,并考虑交通分配模型的基础上,假设连续的交通流分布在城市地区。本文提出了两类模型,包括连续法的理论分析和应用分析:第一,利用约束变分理论和有限元技术建立了一个理论模型,并给出了一个有效的计算算法;与以往的方法不同,该模型处理的是单一出行起点和连续分布出行终点的用户均衡配流问题,作为对理论方法的补充,本文还提出了一个计算城市区域广义交通流分布的连续近似模型。该模型对大规模交通分配问题具有较好的适用性。计算结果与所提出的模型的预期行为相吻合。
