Abstract

Various methods are proposed for the practical use of ITS. We achieve the detection of emergency vehicles such as ambulances and fire engines by measurement which uses a spread-spectrum method. We propose a method in which another vehicle and the signal can detect the position of emergency vehicles. This method transmits different code spread-spectrum signals from the four corners of emergency vehicles. As a result, because the direction from which an emergency vehicle approaches is understood, evasive driving becomes easy for securing the traffic road, and signal control also becomes easy. As a result of experiment an excellent detection result was obtained.

基于码分多址的ITS应急车辆方向探测系统

针对ITS的实际应用，提出了多种方法。我们采用扩频测量的方法实现了对救护车、消防车等紧急车辆的检测。我们提出了一种由另一辆车和信号一起检测紧急车辆位置的方法。该方法从应急车辆的四个角落发射不同的码扩频谱信号。这样一来，由于了解了紧急车辆驶近的方向，使得避让驾驶更容易确保交通道路的安全，信号控制也变得容易。实验结果表明，检测效果良好。
