这项研究调查了一种基于泰国曼谷市区主要道路的常规GPS测量来估计道路交通拥堵程度的替代方法。根据测量的GPS速度的加权指数移动平均，我们将交通拥堵分为三个级别。利用人的感知来获取分类阈值，并对该方法的性能进行了评估。与现有技术相比，我们提出的方法的优点是它简单、易于理解，并且与曼谷现有的交通报告系统兼容
This study investigates an alternative way to estimate degrees of road traffic congestion based on routine GPS measurements from main roads in urban areas of Bangkok, Thailand. We classify three levels of traffic congestion according to the weighted exponential moving averages of measured GPS speed. Human perception is used to obtain classification thresholds and evaluated the performance of the proposed method. The benefits of our proposed method over existing techniques is that it is simple, easy to understand, and compatible with existing traffic report systems in Bangkok
