随着经济的快速增长和城市化进程的加快,我国城市数量也在快速增加,作为解决构筑现代综合交通体系、减轻市区交通压力、分流城市过境交通等方面都有十分重要作用的城市绕城高速公路亦在大量修建或规划。而目前国内绕城高速公路上设置的地点距离标志,由于未考虑绕城高速公路的特殊性,普遍存在预告不清楚的状况。本文分析了绕城高速公路与一般线性高速公路不一样的特点,并详细阐述了大城市在单圈绕城高速公路和2圈绕城高速公路2种不同的条件下,如何进行交通行车路径指引和地点距离预告,并提出了相应的确定方法。
With the rapid economic growth and the acceleration of the process of urbanization, the number of cities in our country is also rapidly increasing. As a city around the city that plays an important role in solving the problems of constructing a modern integrated transportation system, reducing traffic pressure in the urban area and diversion of urban transit traffic, Highways are also under construction or planning. At present, the distance sign of the location set on the Ring Expressway in China is not clear because of the particularity of the Ring Expressway is not considered. This paper analyzes the characteristics of the expressway ring around the city and the general linear highway is not the same, and elaborated on how to carry out the traffic route guidance under the two conditions of the single-ring expressway and the two-ring expressway in the big city And place distance notice, and put forward the corresponding determination method.
