1. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data
Abstract : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.

2. Path Inference of Sparse GPS Probes for Urban Networks : Methods and Applications
Abstract : The application of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place in urban areas with significant number of mobile sensors moving around covering expansive areas of the road network. Most travelers carry with them at least one device with a built-in GPS receiver. READ MORE

3. Discovering Contiguous Sequential Patterns in Network-Constrained Movement
Abstract : A large proportion of movement in urban area is constrained to a road network such as pedestrian, bicycle and vehicle. That movement information is commonly collected by Global Positioning System (GPS) sensor, which has generated large collections of trajectories. READ MORE

4. Urban Travel Time Estimation from Sparse GPS Data : An Efficient and Scalable Approach
Abstract : The use of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place, with significant number of mobile sensors moving around covering expansive areas of the road network. Many travelers carry with them at least one device with a built-in GPS receiver. READ MORE

5. Helping robots help us : Using prior information for localization, navigation, and human-robot interaction
Abstract : Maps are often used to provide information and guide people. Emergency maps or floor plans are often displayed on walls and sketch maps can easily be drawn to give directions. However, robots typically assume that no knowledge of the environment is available before exploration even though making use of prior maps could enhance robotic mapping. READ MORE
