The study of expressway freight efficiency and fuel consumption

摘要

In recent years, vehicle industry has developed rapidly in China. Chinese expressway network becomes the artery in multimodal transportation system, and it improves the rapid improvement of social economy. However, such development is built on the consumption of large quantities limited and non-renewable energy. At the same time it also produced a large number of HC, CO, NO_x, CO_2 and other harmful gases which can cause global warming. How to upgrade the efficiency of expressway cargo transportation system and reduce fuel consumption, and harmful gas emissions is very important. In this paper, researching different types of trucks on the expressway's transport efficiency helps to provide a theoretical basis of how to optimize the structure of the transportation, and combined with vehicle operating characteristics, to discuss how to improve expressway transportation efficiency and reduce energy consumption.
