摘　　要：本文以道路上常见的梯形截面和椭圆形截面两种驼峰减速带作为研究对象,使用高精度的汽车测速设备及软件在道路上进行数据实测,多次测量后提取汽车通过这两种不同截面减速带时不同阶段的车速信号.通过数据统计及对比分析得到:汽车以中低速通过驼峰减速带时,椭圆形截面减速带比梯形截面减速带对汽车的减速效果更为明显.本文研究结果可为道路设计者和管理者提供一定的指导或参考.Two kinds of hump deceleration strips with trapezoid and elliptical cross section were used as the research objects.High precision vehicle speed measuring equipment and software were used to measure data on the road.After multiple measurements,the speed signals at different stages were extracted of the vehicle passing through two different cross section deceleration strips.Through data statistics and comparative analysis,it was concluded that the deceleration strip with elliptical cross section can make more obvious deceleration effect than that of trapezoidal deceleration strip when the car is running at medium and low speed.The conclusions of the study could be a supplementary reference for road designers and administrator.
