激活交通的信号采用相对复杂的控制逻辑调整交通流动。进激活交通的系统的控制变量的介绍贡献系统运作的灵活性和复杂性，并且也与无常复杂化系统。纸建议二试验优化激活的信号参数的方法：控制器参数和分析模型的基本要求，和宏观的计算机模拟。当激活的信号在 0.4 ～ 0.6 的卷 / 能力范围以内操作时，它将创造最重要的好处，这被结束；研究建议在主要的街的最小的绿时间将被使足够长遇见要求的需求，最好在 60% 主要的街能力点。为了少些保证，在激活半的交叉控制延期，车辆扩展的相对小的值(例如， 2.5 s ) 并且最大的绿时间被建议被分到不太重要的街。

英文摘要：

Traffic-actuated signal employs relatively complex control logic to regulate traffic flow. Introduction of control variables into the traffic-actuated system contributes to system operational flexibility and complexity, and also complicates the system with uncertainties. The paper proposes two tentative methods to optimize the actuated signal parameters： basic requirements of controller parameters and analytical model, and macroscopic computer simulation. It is concluded that when the actuated signal operates within the volume/capacity range of 0.4 to 0.6, it will create the most significant benefits; the research suggests that minimum green time in the main street shall be set long enough to meet the required demand, preferably at the 60% of the main street capacity. In order to ensure less control delay in a semi-actuated intersection, relatively small values of vehicle extension （e.g., 2.5 s） and maximum green time are recommended to be assigned to the less important street.
