随着无线通信和移动计算的进步，未来无基础设施的自组织交通信息系统即将实现，车辆之间可以形成网络来交换交通信息。在无基础设施的交通信息系统中，车辆将充当移动传感器并在行驶时收集交通数据。智能手机是交通传感设备的绝佳选择，因为它们现在配备了各种传感器，例如全球定位系统 (GPS) 接收器、加速计、陀螺仪、摄像头和麦克风。这些传感器可用于收集交通数据。尽管有多种类型的传感器可用于交通传感，但过去的研究主要集中在 GPS 接收器上。然而，GPS 接收器会消耗大量电量，因此会显着缩短电池寿命。在本文中，我们探讨了在智能手机上使用其他类型的传感器进行交通传感的可能性。特别是，我们研究了是否可能以及根据加速度计感测的数据来估计车辆速度的准确性。将介绍我们提出的估计方法的准确性。
With the advances in wireless communication and mobile computing, a future infrastructureless self-organizing traffic information system, where vehicles can form a network for exchanging traffic information among themselves, will soon be realized. In an infrastructureless traffic information system, vehicles will act as mobile sensors and collect the traffic data as they travel. Smartphones are a great choice for traffic sensing devices as they are now equipped with a variety of sensors such as global positioning system (GPS) receiver, accelerometer, gyroscope, camera, and microphone. These sensors can be exploited to collect traffic data. Although there are many types of sensors available for traffic sensing, past studies have mainly focused on a GPS receiver. However, a GPS receiver consumes a lot of power and hence it can significantly shorten the battery life. In this paper, we explore the possibility of using other types of sensors on a smart phone for traffic sensing. Particularly, we investigate whether it is possible and how accurate it is to estimate vehicle speed from the data sensed by an accelerometer. The accuracy of our proposed estimation method will be presented.
