摘要
为解决高速公路交通异常事件检测的实时性和可靠性问题,提出了一种基于RFID技术和控制器局域网的预警系统模型和具体架构,分析了系统的工作原理及关键技术。在此基础上,研究了高速公路交通异常事件预警原型系统。实验结果表明,该系统具有反应速度快,可靠性高的特点,能及时向可控范围内的交通参与者发布预警信息,减少交通异常事件带来的人员伤亡与财产损失。
In order to get real-time and reliable traffic incident detection,we proposed the model of the early-warning system for expressway traffic incident based on RFID technology and CAN.Based on the analysis of its working principle and key technology,we developed the prototype of expressway traffic incident early-warning system.The experimental results show that this system has the merits of rapid response and high reliability,which can inform the drivers of the warning information in the controllable area immediately and thus reduce the life and possessions loss further.
