在公路的设计和计划过程中。首先要确定公路技术等级。对一般公路来说,根据其远景设计年限的设计交通量和不同等级公路相适应的设计通行能力作比较来确定该公路的技术等级和车道数目。这样确定的公路技术等级可以提高公路工程和汽车运输的综合经济效益。既可避免凭主观确定公路技术等级产生等级过高或过低而造成的经济损失,又可使公路的修建与汽车运行
In the road design and planning process. First of all, to determine the technical level of the road. For a typical highway, the technical grade of the road and the number of lanes are determined based on a comparison of the designed traffic volume for its long-term design life with the designed capacity for different grades of road. The level of road technology identified in this way can increase the overall economic benefits of road engineering and motor transport. It can not only avoid the subjective determination of the technical level of highway caused by the level of over or under the economic losses, but also make the road construction and operation of the car
