【摘要】 首先引入几个描述交通流的基本函数,接着在交通流连续运动和时断的情况下,分别建立了连续和间断的交通流模型,在此基础上根据微分方程建立红绿下的交通流模型,分析在不同时刻公路上交通流的变化,据此画出在红绿灯模型下的车流密度变化过程,并给出了交通流的红绿灯模型在十字路口的应用.更多还原

【Abstract】 Several basic functions are first introduced to describe the traffic flow. Continuous and intermittent traffic flow models are then built up. Traffic flow models are also built up, based on the differential equation. Changes in traffic flow at different times are analyzed. The whole changing process of its density is obtained. Its application at the crossroads is also proposed.更多还原
