摘要
分析了无线定位技术中的手机定位、传统车载GPS定位以及GPS与GSM双向定位的技术模式,在此基础上提出了一种基于多方式无线定位的交通事件检测系统,该系统主要由报警设备(手机、车载终端)、GSM公众网和后端交通管理中心3部分组成;给出了系统的检测模式、目标人群和系统组织体系;并从检测率、误警率和平均检测时间3个方面对检测性能进行分析,提出了几项提高系统检测性能的方案。
Such technologies as location-based service （LBS）, traditional in-car GPS positioning, and bidirectional positioning of GPS and GSM were analyzed. Based on it, a traffic event detection system based on multi-mode radio positioning was presented. The system was composed of alarming devices（mobile phone, in-car terminal）, GSM public network, and back-end traffic control center. The detection mode, target audience, and structure of the system were presented. The detection performance was analyzed from three aspects of DR, AFAR, and MTD. Some schemes to promote detection performance of the system were put forward.
