Development of reliable transport network system for urban regeneration

该项目旨在探索可靠的交通网络系统的规划和管理，有助于增强城市的活力。为此，研究了1)有助于城市更新的交通系统，2)在实施前用网络可靠性的概念对道路规划进行评价的方法，3)实施后的道路规划评价方法，4)最优交通规划决策模型的数学表述。利用吸收马尔可夫过程的概念，讨论了交通系统规划对城市活动的影响。探讨了外环线建设、市中心改造对交通规划的影响，并比较了不同区位对交通规划的影响；对于第二个分析，提出了用…评价交通规划的方法更多的是旅行时间可靠性的概念。发展了基于确定性用户均衡的方法，因为它提供了唯一的解决方案。利用确定性用户均衡的灵敏度分析思想，构建了基于出行时间可靠性的交通规划评价方法；对于第三种分析，提出了利用交通检测器获得的数据对道路规划实施后的出行时间可靠性进行评价的方法。由于检测器并不能观测到所有的路段，因此我们需要估计未被观测到的路段上的交通量的波动。为此，我们提出了使用路径流估计器的方法。最后，我们旨在建立以最大化网络可靠性指标为目标函数的数学模型，同时考虑预算和环境约束。为此，我们探索了具有平衡约束的数学问题MPEC的求解算法。较少

This project aims at exploring planning and management of reliable transport network system which will contribute to enhance the urban activity. For this purposes researches on 1)transport systems contributing to urban regeneration, 2)evaluation method of road planning by the concept of network reliability before the implementation, 3)evaluation method of road planning after the implementation, and 4)mathematical formulation of optimal transport planning decision model are conducted.For the first analysis, we have explored the structure of transport network system contributing to urban regeneration. By using the concept of absorbing markov processes, the influence of transport system planning onto urban activity is discussed. We have explored the effect of transport planning of construction of outer ring road, redevelopment of city centre and compared the effect of redevelopment by the locations.For the second analysis, we have proposed the methodology to evaluate transport planning by … More the concept of travel time reliability. Methodology based on deterministic user equilibrium is developed since it provides a unique solution. Using the idea of sensitivity analysis for deterministic user equilibrium, methodology for evaluating transport planning from the viewpoint of travel time reliability has constructed.For the third analysis, we have proposed the method for evaluating travel time reliability after the implementation of road planning by using the data obtained by traffic detectors. Since not all links are observed by the detectors, we need to estimate the fluctuation of traffic volumes on the unobserved links. We have proposed the method of using path-flow estimator for this.For the last analysis, we aim at proposing the mathematical model whose objective function is to maximize network reliability measures with the budget and environmental constraints. For this purpose, we have explored the solution algorithms for MPEC(mathematical problem with equilibrium constraints). Less
