Semi-Supervised Deep Learning Approach for Transportation Mode Identification Using GPS Trajectory Data
… transportation modes purely based on their GPS trajectories. First, a segmentation process is developed to partition a user's trip into GPS segments with only one transportation mode. A majority of studies have proposed mode inference models based on hand-crafted features, which might be …

Space-time modeling of urban population daily travel-activity patterns using GPS trajectory data
… evolvement process of these hot spots over time. GPS trajectory data of 536 taxi cabs over twenty-two days in San Francisco were analyzed to demonstrate the effectiveness of the proposed method and reveal collective activity patterns across the city and over time. Taxi passengers' pick-up and …

Exploring Personalized Route Recommendation Based on Travel Behaviors of Historical GPS Trajectories
… from their historical Global Positioning System (GPS) trajectories. The Behavior-based Route Recommendation (BR²) method is proposed to compute personalized routes based exclusively on users’ travel preferences. The concepts of appearance and transition behaviors are defined to describe users’ …

Enriching Digital Maps with Aerial Imagery and GPS Data
… digital street maps from aerial imagery and GPS data. Digital street maps consist of a collection of geometry structures such as a road graph and the semantics associated with the structures, such as the lane count and the speed limit of a road segment. This thesis first proposes two …

GPS kinematic positioning for the airborne laser altimetry at Long Valley, California
… algorithm and software for em-level kinematic GPS (Global Positioning System) data analysis. To assess the accuracy of the software, we use it to determine the trajectory of the aircraft during the surveys at Long Valley, California, in 1993 and 1995. This thesis covers the algorithm …
