This dataset consists of 1,000 processed taxi trajectories over a one year period. Each trajectory is a sequence of neighborhoods in Manhattan visited by a taxi identified by its medallion number. Transitions correspond to pickups and dropoffs and are derived from a sequence of (pickup neighborhood, dropoff neighborhood, timestamp) records. If the next pickup is in the same area as the last dropoff, we do not count it as a transition. There is an additional "outside Manhattan" state that captures locations outside of the borough. The dataset was derived from data collected by Chris Whong via a Freedom of Information Law request.
