In order to reduce the communication time between the high - speed and low - speed flows in 2d space , and to get the optimum interconnecting control of traffic flow to the highway pavement maintenance , the fluid characteristic parameters are utilized to appraise traffic conflict trend 基于减少高速流和低速流在二维空间上的交汇时间,实现高速公路路面养护与交通流关联最佳控制的要求,应用管道流变特性参数解释高速公路养护作业产生的交通冲突特征,建立了控制施工作业设备与高速交通流的数学模型。
