路线的行车效益是与路线的行车性能直接相关的。路线设计要用工程费用——效益分析来评价,这就要求我们先对路线的行车性能作出全面的评价。本文从行驶力学的角度,用行程步长法,通过计算机模拟路线的行车车速分布,分析道路沿线的车速服务水平、油耗分布和行程时间。从而为路线设计提供了设计依据和工作途径。本文还编制了一个计算机评析软件DPR87,使上述工作得以迅速完成。并在计算机辅助设计下,就可获得路线设计最佳服务水平。
The driving benefits of the route are directly related to the driving performance of the route. Route design to use engineering costs - benefit analysis to evaluate, which requires us to make a comprehensive evaluation of the route driving performance. In this paper, from the point of view of traveling mechanics, by using the travel step method, the vehicle speed distribution of the route is simulated by computer, and the service speed, fuel consumption distribution and travel time along the road are analyzed. Thus providing the design basis and working route for route design. This article also prepared a computer analysis software DPR87, so that the above work can be completed quickly. And in computer-aided design, you can get the best service level route design.
