The Developing Tendency Of Container Categories And Its Impact On The Container Transport System

Along with the development of global economy and trade, the structure of merchandise has changed greatly, which is diverting from heavy to light, the container scale has been enlarged by the increasing demand of light cargo. At the same time, because of the modulus incompatibility between international standard container and pallet, some developed countries not only design and take advantage of overlength, overwidth, and overheight containers, but also advise ISO/TC104 to enlarge the container dimensions and gross weight. Due to the changes of container, dimensions and weight will lead to the inefficacy of transportation infrastructure, and it will also cost a lot, so forecasting the development trend of container can be directional to the future construction of infrastructure.Following the principle that cargo density should be close to container special volume capacity coefficient, the paper prescribed the containerable cargo of different categories of containers. Then the factors that influence the development of container categories are analyzed, and a multi-factor dynamic related analysis model is set up. On the basis of this model, the reefer container and dry cargo container 20ft and 40ft volume are forecasted. The ratio of container 20ft and 40ft volume presents container 40ft is more popular in the future. According to the forecast result, the conclusion that the construction of infrastructure shouled be carried out in terms of the primary container, meanwhile, the paper calculated the requirement of railway container wagon based on them.
