Research On The Issues Related To The Freight Overloading Railway Of Full Loaded Shuttle Traffic

With the continuous development of economy, the contradiction between the railwaytransport capacity and the demand is becoming more and more prominent.Overloadingtransportation as an important way to accelerate the circulation of commodities and enhancethe capacity and gradually mature, the21st century, our country have built new moon god,reach, the new moon yellow, such as overloaded freight line, and the existing freightoverloading line technical renovation.Overloading transportation development reduces thecost of railway transportation, to enhance the railway transportation in transportation marketcompetition ability. Rail as the main transportation of inland transportation, for theconstruction of a harmonious society in our country, to keep the sustainable development laida strong foundation.At present, the full loaded shuttle traffic on busy railway has achieved initial results,Butheavy to overloaded freight line to is still in its infancy.Under the principle of "take care"empty railway overloading capacity on the freight line has reached the bottleneck, if you wantto continue to improve the capacity you have to break the principle "to empty take care", aheavy to heavy traffic organization mode.Overloaded freight line to heavy traffic pattern,organization weight on the TDD will give full play of the shuttle has on a line capacity, remitthe contradiction between the demand and supply.Applying the theory of economics and transport organization to explore on the overloadedfreight line organization of our country weight to weight to relevant problems, in order tooverloaded freight line operation on heavy to to provide theoretical basis for the flow patternand methods.In this paper, the main research work and conclusions are as follows:(1) Based on consulting a large number of literature data, in-depth analysis the overloadedfreight line empty and heavy traffic and the status quo of the echo.And organization on thefreight line weight to weight to the feasibility and necessity of traffic flow patterns wereanalyzed, and the listed bank heavy to heavy to advantage.(2) the operation weight to weight to train will have a great influence of freight turnover,this paper adopts the method of comparison, the truck in the process of turnover, changes inthe rate of stopping time, walk limits to explore, to calculate the time change, finally through freight turnover time.(3) to supply demand on da qin freight line USES the grey model GM (1,1) is analyzed,the forecasting results show strong demand for goods, goods attract area growing year byyear.(4) the multi-objective programming model was adopted to da qin freight line to return tothe train operation plan on planning, by using Lingo software solution, the results show thatthe recent cargo demand can be through the operation of5000t train to meet, the forwardcargo demand can be through the operation of5000t and20000t train train combination planto meet.
