摘要
描述一种根据九五国家重点科技攻关"公路投资综合效益分析系统的研究"项目研究成果,开发的汽车运行速度和主要经济指标———发动机油耗的预测和模拟技术。本项技术主要是通过改变道路的几何条件、路面状况、交通量、交通组成、车辆特征、车辆载重和环境等因素,预测和模拟上述任一或组合因素的变化对车辆运行速度和油耗的影响。模拟结果将为进一步研究道路纵断面和平曲线的最佳组合、道路的改建条件和路面大、中修养护时机的确定提供决策和分析的数据基础。
This paper presented a methodology for simulating vehicle speed and fuel consumptions on the basis of models and parameters developed and calibrated from theoretical analysis and road site expreriments.The simulation is carried out through a computer program which enables vehicle speed and fuel consumption to be simulated according to the variation of road geometry and pavement conditions,vehicle type,loading,traffic volume and composition.The simulated results can be further applied to the study of road geometry design,reconstructuon and pavement maintenance.
