描述了一种交通传感技术，该技术利用麦克风阵列来检测道路车辆产生的声波。然后，检测到的声音被数字化，并由现场计算机使用基于相关性的算法进行处理，提取反映道路交通状况的关键数据，例如道路交通状况。现场自动监测道路上车辆的速度和密度。与现有的交通传感器相比，该系统的安装和维护成本较低，并且对周围环境的干扰较小。给出了理论分析、计算机模拟和一些初步实验的结果。
A traffic sensing technique is described which utilizes a microphone array to detect the sound waves generated by the road vehicles. The detected sounds are then digitized and processed by an on-site computer using a correlation based algorithm, which extracts key data reflecting the road traffic conditions, e.g. the speed and density of vehicles on the road, automatically on-site. In comparison with existing traffic sensors, the proposed system offers lower installation and maintenance costs and is less intrusive to the surrounding environment. The results of theoretical analysis, computer simulation and some preliminary experiments are presented.
