传感器技术、无线通信和手持计算设备的最新进展使位置感知服务和代理能够根据用户的位置提供适当的信息和服务。为了提供更优质的服务，需要根据从传感器获取的数据准确地了解和预测用户的行为。我们提出了一种利用GPS获取的步行日志并存储在数据库中来估计行人到达时间的方法。它可以应用于行人导航和实时信息检索，具有较高的精度。该方法从数据库中检索与用户相似的行走轨迹，并估计到达目的地的时间。在评价实验中，我们收集了走同一条路线的行人的行走轨迹，并将我们的方法与基于平均到达时间和外推法的传统方法进行了比较。结果表明，该方法的估计误差小于传统方法的估计误差。特别是，我们的方法显示了一个更好的估计路线，包括一个斜坡，行人的步行模式急剧变化。
Recent advances in sensor technology, wireless communication, and hand held computing devices enable location-aware services and agents that provide appropriate information and services depending on the location of the user. To provide better quality services, it is required to know and predict accurately the behavior of the user based on the data acquired from the sensors. We propose a method to estimate the arrival time of pedestrian using walking logs obtained by the GPS and stored in a database. It can be applied for pedestrian navigation and just-in-time information retrieval with high accuracy. The method retrieves walking trajectories similar to the user’s one from the database and estimates the arrival time to her destination. In the evaluation experiment, we collected walking trajectories of pedestrians who walked the same route, and compared our method with conventional ones based on the average arrival time and the extrapolation method. As a result, the estimation error of our method was smaller than that of the conventional ones. In particular, our method shows a better estimation for a route that includes a slope where the walking pattern of pedestrians drastically change.
