摘要
基于HDM4道路分析预测模型,模拟不同道路养护标准下的汽车尾气排放情况,并结合实际应用,分析公路养护如何影响汽车尾气的排放量。测试结果表明:更大的粗糙度伴随着更多的汽车尾气排放量,此外,行驶速度和汽车尾气排放量正相关,这两个因素都受到养护工程的影响;粗糙度同样影响汽车行驶速度;综合考虑速度和粗糙度的影响,正常养护(相较于不良养护和良好养护)对于控制汽车尾气排放量是最佳的;可以认为理想的养护标准是将粗糙度维持在"平衡点"附近。
Emission model of Highway Development and Management Tool(HDM-4) is used to set up a sample project to simulate different level of maintenance standard and demonstrate how maintenance effects on vehicle emissions. The results suggested that higher road roughness are associated with higher vehicle emission;traveling speed is positively related to vehicle emission;considering the effects of speed and roughness, fair maintenance(compare with good and poor maintenance) is the best for controlling vehicle emission;the ideal maintenance is to remain the roughness around the "balance point".
