【摘要】 应用交通流宏观连续模型，模拟上下游信号灯作异步周期变化的协调信号灯路段的交通流动，经数值计算比较，选择改进Ｍｕｒｍａｎ格式求解．结果表明：改进Ｍｕｒｍａｎ格式能准确捕捉交通流中无振荡“激波”位置．更多还原

【Abstract】 Verified by computation that the modified Murman scheme is able to capture fairly sharp fronts without oscillation in the vicinity of the "shock" in traffic flow. It aims at numerically simulating the problem of coordinated traffic signals with asynchronous cyclical variation at upsteam and downsteam.更多还原
