近年来,内地高速公路已有长足的发展,但还存在着不少问题有待完善。据内地业内人士说,全国高速公路发展的最大问题是不联网,难以发挥规模效应。 目前,内地公路网络技术等级还不高。高速公路、一级、二级公路总里程只占全国公路总里程的12％,国外一般在21％以上。 目前,内地已经建成的高速公路主要解决部分省份特别需要路段的高速陆路交通问题。沪宁、沈大、京津,这些经济最发达地区的高速公路交通问题得到了解决。从高速公路占公路的比重来看,高速公路起码要达到2％左右,才能形成规模。目前全国高速公路只到1％左右,因此还远远达不到路网发展的需要。也就是说,中国公路发展速度很快,但质量不高。 世界第一条高速公路诞生于30年代的德国,到目前为止,全世界已
In recent years, there has been considerable development of the expressway in the Mainland, but many problems still need to be perfected. According to insiders in the Mainland, the biggest problem in the development of the national expressways is that they are not connected to the Internet and it is difficult to exert the economies of scale. At present, the technical level of the mainland road network is not high. The total mileage of highways, first-class and second-class highways accounts for only 12% of the total national highway mileage and generally exceeds 21% in foreign countries. At present, the expressways already built in the Mainland mainly solve the high-speed land transport problems that are particularly needed in some provinces. Shanghai-Nanjing, Shenyang, Beijing and Tianjin, the most economically developed areas of highway traffic problems have been resolved. From the highway accounted for the proportion of highways, the highway at least 2% or so, in order to form a scale. At present, the expressway in the country is only 1% or so, so it still falls far short of the need of road network development. In other words, China’s road development is fast, but the quality is not high. The world’s first highway was born in Germany in the 1930s, so far the rest of the world has been
