一、公路建设 土耳其的公路分为由国家公路、地方公路和乡村公路构成的一般公路和收费高速公路两类。截至到1998年底的公路网总里程为382000km以上。其中,高速公路1750km,国家公路31300km,地方公路29500km,乡村公路320000km。1980年~1998年间,一般公路里程增加极少,而高速公路则从100km以上增长到1750km。 为与欧洲联网,土耳其的高速公路是按照欧洲国际高速公路网南北横断汽车公路的标准设计的,具体数据如下:平地设计车速为120km/h,山区设计车速为80 km/h;车道宽3.75m;中分宽度12m;平地最大坡度3%,山区5%;单侧3车道,市内则为4车道。 一般公路的路面率,国家公路增长最快,从1983年的
First, the road construction Turkey’s roads are divided into by the national highways, local highways and rural roads constitute a general highway and toll expressway two categories. As of the end of 1998 the total mileage of the road network is more than 382000km. Among them, the expressway 1750km, national highway 31300km, local highway 29500km, rural highway 320000km. Between 1980 and 1998, the average mileage of ordinary roads increased very little while that of highways increased from over 100km to 1750km. In order to connect with the European network, the Turkish highway is designed according to the standard of the European International Freeway Network. The detailed data are as follows: the design speed of flat ground is 120km / h, the designed speed of mountain is 80km / h; the lane width is 3.75m ; In the sub-width 12m; flat maximum gradient of 3%, 5% in the mountains; unilateral 3 lanes, the city is 4 lanes. The average highway pavement rate, the fastest growing national highway since 1983
