改革开放以来，我国公路交通有了很大发展。到1997年底，公路通车里程达到122．6万公里，其中，高速公路达到4700多公里。但总体上看，我国公路运输仍处于比较落后的状态，路网规模小，技术水平落后。按国土面积计算，我国每百平方公里拥有公路仅12．8公里，即使是东部沿海地区 Since the reform and opening up, China’s road traffic has made great progress. By the end of 1997, the number of highways opened to traffic reached 1.226 million kilometers, of which over 4,700 kilometers were highways. However, on the whole, the road transport in our country is still in a relatively backward state. The road network is small in scale and the technical level is lagging behind. In terms of land area, there are only 12.8 kilometers of highways per 100 square kilometers in our country, even in the eastern coastal areas
