an Urban Rail Transit Network Analysis Luo Ye (Chang'

an University) Abstract: Xi'

an urban rail transit is rapidly developing. According to the recent plan, urban rail transit will increase from

4 lines at the end of

2018 to

14 lines in 2023, gradually forming a network scale. Base on the theory of complex network, calculating the reliability and scalability of urban rail transit network scale is of great practical significance to improve the reachability of the network and to improve the operational efficiency and anti-destruction ability of the network. In L space, the topological structure of Xi'

an urban rail transit network is established, and the reliability of the whole network is analyzed by means of the indexes such as degree of calculation, average degree, average path length, compactness, clustering coefficient and so on. It is considered that Xi'

an urban rail Traffic network is scale-free network. By studying the anti-destructive ability of the network, the reliability of the network is further studied, and the random network failures are simulated and the performance of the network under deliberate attacks is simulated. The network'

s anti-destruction capability is measured by the change of network efficiency. The results show that the urban rail transit network in Xi'

an is in the process of expansion and expansion. The distribution of node degree is not balanced. It shows robustness to random attacks and obvious vulnerability to intentional attacks. keywords: Xi'

6 总线型拓扑高速铁路通过能力计算 陈然 (江苏警官学院) 摘要: 基于开行方案, 针对列车在总线型拓扑结构高速铁路线上跨线、 混速运行, 利用 图 解法 精确计算线路通过能力.构建以开行列车数最大为目标,运行线间隔时间、动车运用 所存车能力、停站时间、股道数为约束的最大化运行线开行模型.算法原理为先确定瓶颈区 段;

再按瓶颈区段顺序铺画运行线,将运行线耦合度作为启发式信息,利用改进蚁群算法确 定时间窗占用最小的运行线铺画;

每次铺画完后再添加一条满足开行方案的运行线直到无法 铺画;

统计运行图上开行的运行线数即为总线型拓扑线路在该开行方案下的通过能力. 以京 沪高铁为干线、 九条城际 (客专) 为支线, 计算在给定开行方案下的京沪高铁线路通过能力. 关键词:高速铁路;

通过能力计算 The Calculation of Bus Topological Structure High Speed Railway Lines'

Capacity Ran Chen (江苏警官学院) Abstract: Based on the line plan, aimed at operating trains on high speed railway lines of bus topological structure with different speeds, we utilize Graph-Solution Method to calculate the capacity of the main line of the high-speed railway. The objective function of the Capacity Calculation Model is to maximize the number of trains. Constraints concludes the headway, the capacity of the station of restoring EMU, the stopping time, and the number of station tracks. Then the Graph-Solve Method is proposed to solve the model. Firstly, difficult sections should be determined. Secondly, we arrange trains'

operation by difficult sections'

order. The degree of coherence can be used as heuristic information for ant algorithm to complete the timetable with minimum time window. Thirdly, we will insert another train line until we can'
