运用交通流理论确定保证交通安全的最短绿灯时间

Using Theory of Traffic Flow to Induce Minimum Green Light Time

交叉道口信号灯的最短绿灯时间是保证安全的一个重要参数，运用跟驰理论和流体力学模拟理论，提出了车辆感应器道口的信号机最短绿灯时间的计算方法，通过实例分析表明该方法简便可行．

Minimum green light time of signal at crossing road is an important parameter to secure the traffic. This uses the follow car theory and fluid mechanics model to induce the equation of the minimum green light time at cross where there is vehicle inductor,then analyzes it with an example.
