导航是一项基本的人类活动，是一种与目标相关的运动，通过空间和时间到达目的地。地理学家、生理学家、人类学家和心理学家长期以来一直对航行速度的空间和时间方面感兴趣。徒步旅行者、搜索和救援队、消防队员、军队和其他人都是步行导航，他们的成功取决于理解步行导航的动力学如何影响个人能力。这项研究模拟了人类在不同地形的森林环境中导航的移动速度。运动模型的开发使用多个主题的轨迹的时空分析。通过卫星定位从200名参与步行导航的受试者中收集了速度估计值。轨迹数据与土地覆盖数据合并，以分析人类在不同坡度和地形上的导航。概括这些特征提供了沿着沿着未知路线从起点到目的地的移动的导航速度的模型。在轨迹数据的分析中使用了Tobler的远足函数和Naismith规则。从这项研究中创建的模型被证明优于那些经典的人类运动速度估计，预测路线完成时间在10%的准确度（M = 11.1分钟，95% CI [9.8，12.4]分钟）。这些模型有助于解释导航的人类动力学。
Navigation, the goal-related movement through space and time to reach a destination, is a fundamental human activity. Geographers, physiologists, anthropologists, and psychologists have long been interested in the spatial and temporal aspects of navigation speed. Hikers, search and rescue teams, firefighters, the military, and others navigate on foot, and their success depends on understanding how the dynamics of foot-based navigation affect individual capabilities. This research modeled the speed of movement of humans engaged in navigation in wooded environments with varied terrain. Movement models were developed using spatiotemporal analysis of multiple subjects' trajectories. Speed estimates were collected via satellite positioning from 200 subjects engaged in foot-based navigation. Trajectory data were merged with land-cover data to analyze human navigation over varying slopes and terrain. Generalizing these characteristics provided a model of navigational speed of movement from an origin to a destination along an unknown route. Tobler's hiking function and Naismith's rule were used in an analysis of the trajectory data. The model created from this study was shown to outperform those classic human movement speed estimators by predicting route completion time within 10% accuracy (M = 11.1min, 95% CI [9.8, 12.4] min). These models help explain the human dynamics of navigation.]
