摘要我国在道路交通事故中的死亡人数位居世界第一，道路交通安全的形势很严峻。目前，道路车流量日益增加，加上人们在道路事故方面处置没有经验、交通事故检测基础设施缺乏等原因，“二次事故"时有发生。

Title Road Traffic Accident Graded Alarming & Warning System
Abstract
At present, the traffic deaths in China remain the first around the world. As a result, the road traffic safety situation is still serious. With the increasing number of vehicles, the lack of experience on disposal of accidents, and the lack of information collection equipments and/or other factors, traffic accidents together with the “secondary- accident” often occurs.
In this paper, considering some important index, the classification method of traffic accident is proposed, providing the basis for the classification of emergency response. As while, the equipment of automatic alarming on traffic accidents and early warning on secondary accident is designed, which involves acceleration sensor, S3C6410 processor, GPS module, GPRS module and sound-light alarm module. When accidents occur, the device respond and judge accident alert level automatically, at the same time, according to the level of alert, information about the accident such as location, casualties and car damage is sent to relatives, police or paramedics, etc. Meanwhile, warning of secondary accidents is activated by sound-light module, which has a meaningful prospect, as it effectively reduce the casualties and economic losses caused by untimely alarm.
Keywords: traffic accidents; graded traffic accident alarming; early warning of secondary accident
