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 基于減少高速流和低速流在二維空間上的交匯時(shí)間,實(shí)現(xiàn)高速公路路面養(yǎng)護(hù)與交通流關(guān)聯(lián)最佳控制的要求,應(yīng)用管道流變特性參數(shù)解釋高速公路養(yǎng)護(hù)作業(yè)產(chǎn)生的交通沖突特征,建立了控制施工作業(yè)設(shè)備與高速交通流的數(shù)學(xué)模型。
