This paper proposes a novel fixed-primal-dual (FPD) framework combing the primal and dual approaches. In the FPD framework, the train timetabling process is divided into several stages from the time dimension and the sequences of trains within each stage are generated dynamically considering the primal and dual costs of trains. For each stage, a dynamic programming approach is developed to find feasible space-time shortest paths for the trains sequentially. The benefits of our approach are demonstrated by comparing with previously proposed approaches. 60 - Study on the Matching Method Between Tidal Flow of Passengers and Transport Capacity of Line Network in Urban Railway Chen Sixia, Southwest Jiaotong University, Chengdu, 610000, China, Ma Si, Kuniaki Sasaki With the rapid development of urban railway in China, operation plan is becoming complicated, and ridership is increasing simultaneously. A serious problem of urban railway network of Chengdu city is that the distribution of passengers is uneven. It will bring waste of transport capacity. Passenger flow will have a distinct phenomenon at peak hours because of commuting passengers. Finding the regular of passenger flow and then finding the sections where are free

and overloaded in network. Big-small Crossroad Method is useful to balance transport capacity and passenger flow . That method means that instead of running the whole line, some trains only runs a part of line. 61 - Feasibility Analysis of the Implementation of a High Speed Rail Line Reinaldo Crispiniano Garcia, University of Brasilia, 70237-180, Brazil, Rodrigo Vigo Groetaers Vianna, Aline Goulart This works presents a model for the financial analysis of a High Speed Rail Line. It includes economics and social topics besides the need to update the rail cars due to the increase in the demand. Moreover, a case study is presented showing the feasibility of the proposed model. 62 - Analysis on the Development Quality and Scale of Intercity Railway in Yunnan Province Siyu Tao, Southwest Jiaotong University, Chengdu, China, Anjun Li, Zishuai Pang, Tao Feng, Xinmei Chen, Qiyuan Peng Appropriate railway network means not only to meet the need of travel and development, but also to avoid duplication of investment and waste of resources. Initially, Comparative Analysis and Canonical Correlation Analysis are utilized to estimate the current situation of Yunnan province’s railway network. In order to determine a reasonable intercity railway scale, railway network adaptability indicators are integrated to establish a measure model. Meanwhile, referred to similar regional intercity railway projects, the scale of Yunnan provincial intercity railways could be predicted by Linear-regression Analysis. Finally, the development goal of Yunnan intercity railway is put forward. 63 - Research on the Development Patterns of the Urban Functions of The Passenger Transport Hub Siyu Tao, Southwest Jiaotong University, Chengdu, 610031, China, Xinmei Chen, Liwen Wang, Tao Feng, Anjun Li, Qiyuan Peng With the progress of urbanization, green, humane, intelligent and integrated passenger transport hubs are developing. Nowadays, the integrated passenger transport hub is not only planned for transferring, but also providing various urban services. Up to now, the development concept of the urban functions with the traffic station has developed from traditional layout to the mode integrating city and station. Summarize characteristics and adaptability of different modes through the typical cases. The suitable urban function development mode is chosen to guide the transformation and construction of Shapingba integrated hub. 64 - Addressing Orientation-symmetry in the Time Window Assignment Vehicle Routing Problem Kevin Dalmeijer, Erasmus University Rotterdam, Rotterdam, 3000 DR, Netherlands, Guy Desaulniers The Time Window Assignment Vehicle Routing Problem (TWAVRP) is the problem of assigning time windows for delivery before demand volume becomes known. For TWAVRP instances that are difficult to solve by current methods, we observe many similar solutions in which one or more routes have a different orientation, i.e., the clients are visited in the reverse order. We introduce a new branching method that eliminates this orientation-symmetry from the search tree, and we present enhancements to make this method efficient in practice. Through computational experiments, we show that our algorithm outperforms other solution methods, and we solve 29 previously unsolved benchmark instances to optimality. 65 - Real World VRP Needs a GIS Shubhada Devidas Kshirsagar, Product Engineer, ESRI, Redlands, CA, 92373, United States, Heather Moe The Vehicle Routing Problem (VRP) becomes much more complex when the solutions need to be deployed in the real world. To produce an operational result, the VRP model must include geographically precise inputs. The best way to integrate this massive amount of information is to use a Geographic Information System (GIS) in the problem-solving methodology. This presentation will discuss requirements from a wide range of commercial and public-sector clients over 30 years . With the described GIS inputs, the VRP model will produce a route plan that is both cost efficient and realistic. 66 - Research on Multi-objective Optimization of Multimodal Transportation Routing Choice: Take Chengdu-Lodz Express as an Example Yang Ge, Southwest Jiaotong University, Chengdu, China, Yinying Tang, Qinglin Li, Li Yu In order to improve the efficiency of CHINA RAILWAY Express, the four indicators of transportation cost, transportation time, transportation quality and international influence are selected as optimization objectives. Considering time window constraints, a multi-objective optimization model for multimodal transport routes is established for designated OD. An improved genetic algorithm is designed to solve the model, and the validity of the model is verified by real data between Chengdu and Lodz. The results show that: transport costs significantly affect the results of the path selection, and the transportation costs restrict the international influence mutually.
