一、关于道路功能问题 工业企业内部的道路有不同于城市道路的功能特点,它们是企业道路造型设计的基础,设计中必须考虑这些特点。 (一)工业企业内部道路的宽度一般远小于城市街道,道路设计中必须尽量选用较小的路面宽度,使同一道路能够适应多种功能要求,严格注意节约厂内用地。 (二)厂内行车速度一般均小于城市交通,这和厂内交叉口较多、行车视距有限等因素有关。常见货运汽车速度一般为15～20公里/小时,最高速度应不超过25～30公里/小时。从最佳通行能量和保证交通安全两方面考虑,这一速度是经济合理的。
I. About the function of roads The roads within industrial enterprises are different from the functional features of urban roads. They are the basis of the design of roads for enterprises and must be taken into consideration in design. (1) The width of the internal roads of industrial enterprises is generally much smaller than that of city streets. In the design of roads, it is necessary to use smaller road widths as much as possible, so that the same road can be adapted to various functional requirements and strict attention should be paid to saving land in the factory. (2) The speed of the vehicles in the factory is generally less than that of the urban traffic. This is related to the fact that there are many intersections within the factory and there is a limited viewing distance. The speed of common freight cars is generally 15 to 20 km/h, and the maximum speed should not exceed 25 to 30 km/h. Considering both the best traffic energy and the guarantee of traffic safety, this speed is economically reasonable.
