Research On The Interrelated Problems Of Transportation For Zhengzhou-Wuhan Passenger Dedicated Line

With the development of economy and the improvement of people's standard of living, passenger transport is required more in efficiency. But the speed of passenger and freight cars paces back and forth at a low level in our country. The low speed of train running is still a vital factor that limits the development of the railway. Passenger transport special line are being built on a large scale, in order to easy the contradiction of rapidly increasing transportation demand and seriously shortage of railway transport capacity. Driving the speeding-up of trains is the one of emphatic strategies that achieves modernization and development of railway by strides. Therefore, constructing passenger dedicated line is a significant strategy and direction which our country railroad develops.The one of the important parts of "Beijing-Guangzhou passenger dedicated line",Zhengzhou-Wuhan passenger dedicated line is a background for research in the thesis.Firstly, this thesis collects main social economic characteristic communications and transportation situation of Zhengzhou-Wuhan passenger dedicated line, analyze position and function that it is in the road network, study its current situation and future development trend, and make a prediction the flows and the volume of guest's and goods to the near, long-term of the railway with the science and rational method.Secondly, after thorough analyzed deducting coefficient of the passenger transportation special line train and determined deducting coefficient in the different speed train combination, this article calculates carrying capacity of Zhengzhou-Wuhan passenger dedicated line by using the way of deducting coefficient calculated existing high speed the carrying capacity; On basis of the way of deducting coefficient calculated existing high speed the carrying capacity, it also calculates carrying capacity by using the way of average minimum time interval between trains ,and analyzes the adaptability of carrying capacity, and separately calculates carrying capacity in the prime time and the non- prime time. And it analyzes the adaptability of carrying capacity.Finally, in order to make scientific and reasonable passenger train plan for dedicated passenger traffic lines, sum up current the domestic and foreign research results, each factor influencing the plan is analyzed systematically, on basis of this, integrated and optimal model is built up. This paper establishes optimization model of passenger train plan, solving thinking is resulted on the model of analysis for thinking, according to solving thinking Zhengzhou-Wuhan special line for passenger train and the cross-line trains are summed up.
