It s hardware consists of five parts,namely,a sensor master tester,display,print and an alarm unit,because the sensor which is masked by metal film uses modulating and inducing technology,its zero offset is reduced,its ability of an interference is raised,the design realized the high reliability,stabi.

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.
