利用实地观测数据采用正交试验方法对施工区微观仿真模型进行了标定,接着对不同交通量与车辆组成条件下速度标准差随限速值的大小变化进行了仿真,并建立了两者之间的模型,研究表明施工区段相对上游非施工区段速度减小30 km/h能使速度标准差达到最小并能兼顾通行能力的要求。
The orthogonal experimental method was used to calibrate the microscopic simulation model in the construction area by using the field observation data. Then the velocity standard deviation under the different traffic volume and vehicle composition was simulated with the change of the speed limit value, and the relationship between the two was established The results show that the reduction of 30 km / h in the construction section relative to the upstream non-construction section can minimize the standard deviation of speed and balance the requirements of traffic capacity.
