an empirical study on the design of china high speed rail express train Operation Plan from a sustainable transport perspective
Sustainability, 2018Co-Authors: Maoxiang Lang, Yang Gao, Kai Wang, Sangbing Tsai, Mingkun HuoAbstract:The sustained and steady development of China’s economy has led to the rapid improvement of the logistics. At the same time, the rise of the e-commerce mode has given rise to a huge demand for express delivery and the express industry has entered a period of boom. Fortunately, China’s high-speed rail network has been networked, and the development of a high-speed rail express train has entered the test stage. After the high-speed rail express train is put into use, it could effectively relieve the pressure of highway transportation and significantly reduce transport pollution. To make better use of high-speed rail transport resources and give full play to its green and efficient advantages, this study established a two-stage model of a high-speed rail express train Operation Plan. In the first stage, a train candidate set generation model aiming for the minimum total cost of train Operation was established that considered the high-speed line carrying capacity, section flow capacity, and OD requirement satisfaction constraints, which reduces the scale of train spare parts and improves the efficiency of solution. In addition, a column generation algorithm was designed to solve the model. In the second stage, an accurate flow distribution model aiming for the optimal economic efficiency was established, and then the high-speed express train Operation Plan was designed completely. The computational results are encouraging and demonstrate the effectiveness of the model and solution method.

optimal Operation Plan of the online electric vehicle system through establishment of a dc distribution system
IEEE Transactions on Power Electronics, 2013Co-Authors: Seungmin Jung, Hansang Lee, Chong Suk Song, Jonghoon Han, Woonki Han, Gilsoo JangAbstract:Owing to the consistent increase in energy efficiency issues, studies for improving the charging efficiency and energy density of batteries have been receiving attention in the electric vehicle transportation sector. This paper deals with an online electric vehicle (OLEV) system which utilizes the dc power system for reducing loss as well as reducing the size of the required battery capacity. Intensive research on grid integration with OLEV has not been performed until recently and it is necessary to calculate the power flow analysis considering the unique characteristics of OLEV for the commercialization of this new transport system (for the application of this new system in the transport sector). In this paper, the dc OLEV power system is being investigated for reducing line losses and peak power thereby reducing the electric cost levied on the substation. Verification processes are performed through simulation for various scenarios to examine the effectiveness of the proposed system in terms of power consumption, battery state of charge, peak power, and loss reduction.

the optimization of urban rail transit s train Operation Plan in non peak period based on coordinated transfer
Third International Conference on Transportation Engineering (ICTE)American Society of Civil EngineersChina Communications and Transportation Associat, 2011Co-Authors: Peng Sun, Hu XiaoAbstract:In recent years, with the accelerating process of urbanization, urban rail transit have been rapidly developing in China's megacities. From the experience of construction and Operation of rail transit in our country at this stage, the transfer behavior between lines accounts for a great proportion in the total trip amount undertaken by rail transit due to the limitations of rail network coverage. Meanwhile, the consideration of coordinated transfer is comparatively insufficient. In this paper , In response to the characteristics of urban rail transit's transfer, and taken the convenience of the transfer between lines into consideration, the train Operation Plan of rail transit in non-peak period is optimized targeting on minimum cost of system transfer. And the optimization model of rail transit's train Operation Plan in non-peak period is obtained by proposing the computing method of total transfer cost. After checking the validity of the model , the new optimized train Operation Plan shows significant reduce of passenger's transfer time in non-peak period. The study can be used as reference to the optimization of train Operation Plan.
