由于最近的社会趋势，加强汽车安全是非常必要的。作为环境交通信息的一部分，通过对声源的分析，可以估计出驶近车辆的方向。当能见度较差时，该系统可向十字路口的司机提供接近车辆的信息。为了防止交通事故的发生，有必要更准确、更快速地检测驶近车辆的方向。本文介绍了一种利用均匀线性传声器阵列（4个传声器）估计接近车辆方向的方法。我们采用相关方法来实现声源定位，并在Carter， G. C.和Abraham， P. B.（1980）中提出了三次样条插值的方向估计方法。实验表明，该方案具有良好的性能。
Due to recent trends in society, enhanced car safety is strongly required. As one piece of environmental traffic information, the direction of approaching vehicles can be estimated from an analysis of sound sources. This gives information of approaching vehicles to drivers at intersections when visibility is poor. To prevent traffic accidents, it is necessary to detect the direction of approaching vehicles more accurately and rapidly. This paper describes a scheme that uses a uniform linear microphone array with four microphones to estimate the direction of approaching vehicles. We employ a correlation method to realize sound source localization and we propose a direction estimation method with cubic spline interpolation in Carter, G. C. and Abraham, P. B. (1980). Trials show that the proposed scheme offers good performance.
