With the city subway and high speed rail opened, development of rail transit pays more and more people's attention. And the pantograph is the primary means of train running at high speed to get power. Using Simulink and dSPACE in combination, real-time captures the pantograph and catenary's motion. According to the state of the pantograph’s motion, analyses physical model, so as to achieve the purpose of independent manufacturing pantograph pantograph.

With urbanization process acceleration in China, traffic travel among cities becomes increasing, and traffic mode split is the key link of traffic passenger flow forecast among cities. In this paper, the concept of high-density town cluster was proposed to analyze the characteristics of development, population composition, and traffic facilities among high-density town cluster. Based on applicability analysis of aggregate model and disaggregate model, survey content of revealed preference (RP) and stared preference (SP), and traffic mode hierarchical division according to average speed, then NL disaggregate model among high-density town cluster was constructed. NL model which was parameter calibrated and validated with DongGuan citizen travel investigation data in 2009 was used to analyze the trend of traffic mode split. The result shows that high-density town cluster, such as DongGuan, are establishing a three-dimensional travel mode set, including high-speed rail, intercity rail, suburban rail, urban rail transit, intercity express bus, car, taxi, and common public transport. With the network of multi-mode rail transit further improving, ratio on choosing the traffic mode of multi-mode rail transit, such as high-speed rail, intercity rail, suburban rail, urban rail transit, increases dramatically.

This impacts of high-speed rail transit, such as the Japanese Shinkansen the first high-speed rail in the world, has been contributed on regional structure or regional systems. The previous study has been mainly centered on many aspects. Does construction of high-speed rail transit in less-developed or remote regions lead to economic activity or population dispersion from developed regions, and thus, lead to the reduced regional disparities? Traditionally, answers to such questions would be obtained through large-scale multi-regional econometric models, which are capable of predicting inter-regional trade. Detailed models are more general in the sense that they can provide richer information in response to various policy variables. The construction of high-speed rail (HSR) is very populous in China. It is no doubt that the HSR will have great impact on the regional development and bring great beneficial economic and social effects. In this paper, the HSR and impact on the regional development is summarized. The first high-speed intercity line from Beijing to Tianjin, which became operational since 2008, has being creating positive impacts on regional economic development and other aspects.
