续进式绿波协调和同步式绿波协调，均为经典干线协调控制策略。我国传统使用的续进式绿波协调策略，已无法满足高饱和度交通流的需求，甚至会对复杂多变的交通状况产生负面影响。续进式绿波控制在过饱和状态的失效机理，是由于续进式协调控制中上游交叉口先放行，当下游交叉口排队未完全消散时，导致上游绿灯初期放行车辆的二次停车，造成延误增大甚至排队溢出。过饱和状态时，同步式绿波协调更有利于车辆连续不间断地通过交叉口群，车速越高则绿波带越宽，控制效果越显著。以此为基础，基于 Vissim 仿真的建模分析，对比分析了不同交通饱和度，尤其是过饱和状态下，2种干线协调控制策略效果，并对结论进行了实例验证。

Simultaneous system and progressive system are two classic control systems in transportation .The tradi-tional progressive systems currently used in China are not sufficient to deal with high-saturation traffic flows .Further-more ,it even worsens the complex traffic conditions by inappropriate control strategies .For traffic states in high satura-tion ,the reason why progressive system doesn't work is analyzed ,and the simultaneous system as the signal control strat-egy is proposed .Based on the theory analysis ,effects of these two signal control strategies are compared in different satu-rations with Vissim simulation .The conclusion is drawn and proved with certain cases .
