摘要
为建立高速公路作业区限速标志下的车速选择模型,文中利用VISSIM仿真数据、实测数据分别对模型进行标定和验证,模型的相对误差小于5.0%。结果显示,驾驶人经过限速标志后车速降低,但限速效果与限速值的大小有关,限速值差别较小时限速效果好。因此,可以在作业区内每隔一段距离依次设置数值递减的限速标志,以提升限速效果。
In order to establish the speed selection model under speed limit signs of highway work zone,VISSIM simulation data and measured data are used to calibrate and verify the model,and the relative error is less than 5.0%.The results show that the speed will cut down when drivers pass through the speed limit sign.But the speed limit effect is related to the value.When the value difference is small,the effect is better.Therefore,the speed limit signs with decreasing values can be set at intervals in the work zone to improve the speed limit effect.
