Capacity Research in Urban Rail-bounded Transportation with Special Consideration of Mixed Traffic

在城市混合交通区，轨道交通受到个体交通的强烈影响，个体交通由个体车辆和行人组成。因此，城市混合交通也影响了轨道交通系统的通行能力研究结果。为了提高城市轨道交通系统容量研究的准确性，本文提出了一种考虑混合交通的城市轨道交通仿真模型，并对各种影响进行了系统的通用随机描述。由于城市轨道交通的随机性影响，通过容量研究的模拟方法得出的等待时间函数将适用于混合交通条件。对于现有的方法，该过程的时间和费用必须大大减少，并适应各种调查情况的模型的灵活性必须提高;此外，城市轨道交通和个人交通之间的相互作用的系统的方法论描述的相关模型必须表示。将开发两种方法。一种方法-建模方法-是开发一种系统的评估方法，该方法可独立于具体应用程序用于确定重要的基础设施部分。在这些基础设施路段上，个体交通被建模为模型中的铁路限界交通。该方法可以利用已有的知识，在仿真中直观、全面地描述轨道交通对城市轨道交通的影响。必须推导出个体交通和轨道交通的交通负荷变化率。另一种方法--分布方法--包括将个体运输造成的随机影响描述为数学分布的扰动。此外，通过系统的分析和归类，将一些本质性的影响转化为仿真方法中轨道边界模型的特性，简化了某些典型情况下随机影响的描述。为了进行分析和分类，将事先审查数据收集和影响的敏感性分析。将这两种方法与现有的方法进行比较，并将描述这两种方法的改进。此外，这两种方法的影响的比较将通过使用各种应用程序来暴露。

In urban mixed traffic zones, the rail-bounded transport is strongly influenced by the individual transport, which is comprised of individual vehicles and pedestrians. Accordingly, the urban mixed traffic also impacts on the results of capacity research of rail-bounded systems. In order to improve the accuracy of capacity research for urban rail-bounded systems, a simulation model for urban rail-bounded transport with consideration of mixed traffic integrated with the systematic universal stochastic description of the various influences will be derived in this proposed research project. As a result of the stochastic influences on urban rail-bounded transport, the waiting time function, which results from the simulation methodology of capacity research will be adapted to mixed traffic conditions. For the existing method, the time and expenses for the process have to be considerably reduced, and the flexibility of model adapted to various investigated situations has to be improved; in addition, the systematic methodological description of the interaction between the urban rail-bounded transport and individual transport in correlation to the model has to be represented. There are two approaches will be developed. One approach - the Modeling Approach - is by developing a systematic assessment method, which can be used independently of specific applications for the determination of the significant infrastructure sections. On these infrastructure sections, the individual transportation is modeled as rail-bounded transport in model. With this approach, the influences on urban rail-bounded transport can be universally described directly in simulation by usage of existing knowledge. The different changing rates of traffic loads between individual and rail-bounded transportation have to be derived. Another approach - the Distribution Approach - includes the description of the stochastic influences caused by individual transportation as perturbation by mathematical distributions. Moreover, through a systematic analysis and categorization, some of the essential influences can be transferred into the characteristics of the rail-bounded model in the simulation method, which simplifies the description of the stochastic influences in certain typical situations. For analysis and categorization, gathering of data and sensitivity analysis for influences will be examined in advance. The two approaches will be compared with the existing method and the improvement of the two approaches will be described. In addition, the comparison of the impacts of the two approaches will be exposed by using various applications.
