Real Trajectory Data
The trajectory data provided below is obtained from the GPS reading systems carried by two of our lab members during their daily commute for 6 months. Each trajectory represents a continuous trip of a member in the Cook county and/or the Dupage county of Illinois. The trajectory was sampled every second. Each sample record in a trajectory file follows the following format:
Latitude | Longitude | Time | x_projection | y_projection
Time is the USA central time. After 7pm, the hour part of the time is a negative value h. The actual hour is h+24. x_projection and y_projection represent the coordinate projected from <Latitude, Longitude> using the projection of NAD 1983 HARN StatePlane Illinois East included in ESRI ArcView 3.1.
