模型的特点是每一步纳入多个交叉口，进入优化范围，并使用同一步长一次完成增加全系统带宽的优化。

The character of the model is to keep many intersections into the optimized scope per step and to use the same step length to finish the adding bandwidth optimization at one time.

给出进口道通行能力与信号周期之间关系的判断准则，并运用该准则进一步分析整个交叉口的通行能力与信号周期的关系。

The criterion to estimate the above relationship was presented, which was then used to analyse the relationship between Capacity and cYcle length for a signalized intersection as a whole.
