按公路线形确定行车速度和燃油消耗

本文根据大量野外调查与实测数据,辅以理论分析,建立了公路线形与行车速度之间的关系。根据沿线行车速度和道路阻抗,可以估算燃油消耗量。采用本文提供的曲线图或电算程序,易于绘出某一给定公路沿线行车速度和燃油消耗变化的曲线图。本文的研究成果在公路方案的合理评价和优化设计中有实用意义。

Determination of Vehicle Velocity and Oil Consumption According to Highway Alignment

By means of massive field observations and measurements, accompanied with theoretical analysis, the relationship between the vehicle velocity and highway alignment has been established. According to the vehicle velocity and road resistance along the line, the oil consumption could be estimated. By using provided diagrams or computer program one could easily draw out the evaluating chart of vehicle velocity variation together with oil consumption along a given highway line. The results of this paper are of great significance in rational evaluation and optimal design of a highway project.
