Abstract :
Summary form only given. GPS is one of the best sensors ever. Besides its traditional applications for consumers and business, engineers and researchers continue to find innovative ways to use it. We have been collecting GPS data from vehicles and people for the past six years, with over 155 million GPS points collected from about 700 different cars and individuals. In this talk, I describe our research at Microsoft in using GPS data to model and predict where people go, investigate location privacy, and create road maps. I also talk about some practical tools for research like this, some pitfalls, and ideas for new projects.
