The process of realizing actuated signal control and some interrelated techniques based on Paramics were put forward.

This paper introduces the mechanism of actuated signal control and the method to determine main parameters, analyses the queuing model and the delay model at urban road intersections, surveys the basic data of a typical four-leg signalized intersection in Beijing, simulates the present situation and the actuated signal controlled situation and compares the two results.

This paper briefly introduces the superiority,limitation,basic working principles and control parameters of actuated signal control.

Aiming at the quality problems of road traffic signal controller in China and based on deep investigation on signal controller industry,this paper firstly analyzes the developing situation,authentication system and compulsory test system of signal controller at home and abroad.

The application of embedded technology to the isolated signal control system can not only make possible the self-adaptive optimization of time plan in the signal controller,but also supervise the isolated signal status through the remote control center,which paves a solid ground for embedding isolated intersection adaptive control system into the whole urban traffic control system.

This paper studies Wuyi Road and adjacent areas by experiment based on Urbansim which is a an urban traffic street network simulation system developed from CORSIM and on inductive control principle which is relatively successful abroad.
