公交车辆班次供应智能监管技术浅析

上海市城市交通运输管理处已建成一套基于GPS定位技术的公交车辆营运监管系统,可以对线路车辆班次供应情况进行智能化监管,该系统的数据主要由车载GPS终端分发获取,由于GPS技术本身的局限性,使得车辆在首末站数据包丢失,无法做到准确统计.本文提出远距离射频识别技术与GPS技术相结合的办法,可以使公交车辆经过首末站的识别率达...

The Use of Intelligent Control Technology on Bus Shifts Shanghai City Transportation Management Office

Shanghai City Transportation Management Office has built a public transport vehicle operation supervision system based on GPS technique which provides the intelligent management of the supply situation of bus shifts in lines. The data of the system mainly comes from on-board GPS terminals. Due to the limitation of GPS technology itself, it＇s impossible to obtain accurate statistics because of the loss of data packets at ends of lines. This paper puts forward a method of combining RFID technology and GPS technology, improving the recognition rate up to 99.5% for buses passing through the stations at ends of lines, and ensuring the accuracy and authority of statistics on bus shift supply.
