Disigning The Freight Transport Products Under The Separation Of Railway Passenger And Freight Line

For a long time, railway carrying capacity is limited on the most railway lines in China. The railway's traffic capacity has not been meet ever-increasing passenger and cargo transport demands. The competitive phenomenon of traffic capacity is universal between passenger and cargo transportation on some busy lines. The demands of passenger transport around the Chinese lunar new year is big, so the railway department have to drop some cargo traffic demands to meet increasing passenger demands in this time. The situation of cargo transport capacity shortage will more aggravated. In recent years, the railway department drew a wonderful blueprint of great-leap-forward development to relieve the situation which the velocity of railway construction and national economy development is out of step, and carried out some improved steps, such as increasing the railway operation mileage, optimizing the railway network structure, improving the condition of railway facility instrument, planning and constructing the "four'vertical'and four'horizontal'passenger special line network". Above steps make the separation of passenger and freight traffic a reality.This paper is set in separation of passenger and freight traffic, and study on railway freight transport product development and layout. In the past, the railway operation mode is mixed freight and passenger traffic, so the structure of railway freight transport product is single relatively. The speed of freight transport product is lower, usually, is under 80km/h. the type of freight transport product is through train, transit train, section train, goods collecting train and exchange train. The freight transportation will improve by a large margin after separation of passenger and freight traffic, so the freight transport product will be various in forms on speed, load and haul distance to'enrich the system of freight transport product.The paper study on the some aspect as follows:first of all, the paper study the freight transport demands under the characteristics of China railway, and divide freight transport demands into basal layer, intermediate layer and high-end layer, then divide freight transport demands of every layer into different kinds demand. Secondly, the paper indicated four kinds strategy when develop railway freight product as follows:function innovation, formal innovation, structure innovation and layout innovation, and analyses the ten product function combined. Thirdly, the paper analyses the situation of product combined on two and three speed level, and the date-base of the relation between demand layer and product category. At last, build the model of mixed integer programming to deal with the problem of product layout.The paper considers the freight transport demands layer decide to the public strength, the structure and layout of freight transport product. Diversification of freight transport product is inexorable trend, so the study on layout of freight transport product has important meaning.
