摘要
SCOOT系统是一种交通诱导系统,它通过采集交通数据实时地调整绿信比、周期长、相位.大多SCOOT系统采用传统的车辆检测技术,该技术的缺点是实时准确性较差、建造维修成本高、使用寿命短、容易受天气环境干扰等.分析了SCOOT系统的原理与结构.着重分析了蓝牙车辆检测技术的模型、流程、原理及在SCOOT系统中的应用,得出蓝牙车辆检测器可以弥补SCOOT系统在数据采集方面不足的结论.
The SCOOT system is a route guidance system, which can adjust green ratio, length of period and phase on real time by collecting traffic data. Most of SCOOT system adopts traditional vehicle detection technology, whose disadvantages lie in bad real-time accuracg, high production and maintenance cost, short service life, and easy disturbance from weather environment. The principle and structure of SCOOT system are analysed. The model, flow, principle and its application in SCOOT system of Bluetooth vehicle detection system are emphatically discussed. Finally, the conclusion is obtained that this system can compensate the defect of SCOOT in data collection.
