摘 要
本论文首先对中国道路运输及运输中所存在的一些主要问题进行陈述分析，针对里面涉及的相关问题进行客观的分析论证并提出解决办法。最近这几年我国的道路运输行业保持着快速的发展，稳步的增长着的势头，透过近年国内的经济发展的大数据数据和国内变化的日新月异，可以很有底气的断言，伴随着国内经济的发展，国家对国内的对运输行业也会越来越重视，随着对物流的需求尤其是运输行业的拉动，国内的货运市场总体规模在近几年里面会继续扩大，我国运输业在整个国民经济建设中和国家的发展步伐的跟进中变得更加重要。但是，随着近些年国内道路运输的急速发展，货物运输的基础设施却没有及时跟得上运输整体的运输能力，导致道路运输行业的及时性和快速反应性受到极大的限制，本论文就是针对目前中国道路运输的基础设施—货车，提出一些解决和优化的方法。

Abstract
This paper first of China's road transport and transport in the presence of some of the main problems of the analysis, in view of the relevant issues involved in the objective analysis of the demonstration and put forward solutions. In the recent years, China's road transport industry maintained rapid development, the momentum of steady growth, through in recent years, the domestic economic development of big data data and domestic changes with each passing day, can be very confident assertions, along with the development of the domestic economy, the state of domestic for the transport industry will pay more and more attention to, especially with the pull of the transport industry to the logistics demand. Domestic freight the overall size of the market in recent years will continue to expand, the transportation industry in the development of the national economy artery will be more and more obvious. But with the rapid development in recent years, the domestic road transport, cargo transportation infrastructure did not timely and on the overall transport transport capacity, resulting in the timeliness of the road transport industry and rapid response is extremely limited, this paper is in view of the current China road transport infrastructure - truck proposed some solutions and optimization method
