Transit Study

Urban rail transit is one of the important transportation means. Passenger evacuation capacity of subway station is importance for rail operation safety. This article studied the time variation about different numbers of evacuated people under the different stairs width. And it forced on the variation of the evacuation time under different stair widths. By considering the mutual repulsion between pedestrian and wall, and among pedestrians, the article used the anylogic simulation software to simulate and got the evacuation time under different stair-width. When down-stair width is beyond by 3.5m, down-stair-width increasing is unobvious to shorten the evacuation time. Finally, the article explains differences between two results by comparing analysis of simulation results and calculation results.

There are many ticket gates at the subway station. The managers are quite careful about the load degree of the ticket gates. This paper studies two different methods to calculate the load degree of the ticket gates. One is based on the station ticket gates group as the research object, and the other one is based on the volume of passenger flow passing in and out of the station as the research object. Then we use the data investigated at Chaoyangmen station in Beijing to test and verify both of the methods. At last, we can get the conclusion that we can get the same result by the two methods, but the method of based on the volume of passenger flow passing in and out of the station is more reasonable.

Urban Rail

As one of the most important urban commuter transportation modes, urban rail transit (URT) has been acting as a key solution for supporting mobility needs in high-density urban areas. However, in recent years, high frequency of unexpected events has caused serious service disruptions in URT system, greatly harming passenger safety and resulting in severe traffic delays. Therefore, there is an urgent need to study emergency evacuation problem in URT. In this paper, a method of bus dynamic coscheduling is proposed and two models are built based on different evacuation destinations including URT stations and surrounding bus parking spots. A dynamic coscheduling scheme for buses can be obtained by the models. In the model solution process, a new concept—the equivalent parking spot—is proposed to transform the nonlinear model into an integer linear programming (ILP) problem. A case study is conducted to verify the feasibility of models. Also, sensitivity analysis of two vital factors is carried out to analyze their effects on the total evacuation time. The results reveal that the designed capacity of buses has a negative influence on the total evacuation time, while an increase in the number of passengers has a positive effect. Finally, some significant optimizing strategies are proposed.

Utilization Scheme

In order to restrict the boosting of the voltage of the DC bus in the urban rail transit during the regenerative braking and enhance the utilization rate of the regenerative braking energy, two kinds of inverter based regenerative braking energy feedback schemes are studied, the features and application occasions of which are analyzed in detail. The simulation results verify that this method could effectively restrain the boosting of the DC bus and achieves the goals of energy conservation and reactive compensation.

Guiding Effect

With the improvement of Beijing urban rail transit network, an increasing number of transfer stations come into being. The scale of the urban rail transit station becomes larger and the passenger flow volume increases dramatically which makes urban rail transit guidance information much more important. However, since the construction of urban rail transit system in China started relatively late, guiding sign system lacks of uniform standard and guidance information settings have many drawbacks so that it can hardly meet the demand of passengers. This paper, taking television as a carrier. And it gives the thought of removing guidance information to the carriage to serve arriving passengers in advance for best guiding effect. First, design a questionnaire and then issue questionnaires. Second, analyze the survey data and find out passengers’ demand for guidance information. Third, design a scheme on guidance information based on passengers’ demand. At last, use AnyLogic simulation software and select line 2 platform of Xizhimen station as a simulation environment to evaluate the effect of the scheme.

Urban Rail Transit (URT) is more and more popular with citizens. Evacuation capability of stations is concerned with their service levels. When emergencies occur, passengers' safety is threatened. 3-line Xizhimen Station is taken with M/G/c/c theory for an example. By analyzing evacuation capability of stairs and passageways, evacuation bottlenecks are found to improve the service level of Xizhimen subway station.

As an important urban rail transit, the metro has become one of the standards to measure whether the city belongs to modern internationalized destinations or not. Though the space of subway station is relatively small, the metro comprehensive pipeline is an important part of the subway station and includes a huge variety and quantity. During the design process of metro comprehensive pipelines, pipeline collision happens frequently. On Three-Dimensional design platform based on BIM technology, pipeline design has already been mature. This paper puts forward adjustment algorithms about metro comprehensive pipeline collision and they are both flexible and easy to realize and adapt to any Three-Dimensional platform based on BIM technology

The development of rail transit and the construction above subway station (CASS) will have profound influence on city. This paper tries to take Tianjin’s practical situation into consideration, and after analyzing the theories and CASS in and abroad, attempts to find objective law between rail transit and urban development in Tianjin from the interaction of M1 (Metro 1 of Tianjin subway system) construction and urban development. Base on the existing problems and experience, this paper puts forward the methods of exploitation above subway station and the qualitative indicators. Then take an under construction station’s exploitation as an example, raising qualitative principles and quantitative indicators to the site construction nearby. By doing this, aim at leading the future CASS and realizing the harmonious interaction between the development of urban rail transit and land use above it.
