From traces to trajectories: How well can we guess activity locations from mobile phone traces?
We develop a procedure to generate a simulated mobile phone dataset containing ground truth information on locations visited. We develop improved models to identify locations visited. The distribution of the locations visited matches the ground truth well. 70% and 97% of identified homes are within 100 and 1000m from the truth. 65% and 86% of identified workplaces are within 100 and 1000m from the truth.
