Human mobility data collected from five different sites.

We collected human mobilicty traces from five different sites - two university campuses (NCSU and KAIST), New York City, Disney World (Orlando), and North Carolina state fair.

date/time of measurement start: 2006-08-26

date/time of measurement end: 2008-04-18

collection environment: Five sites are chosen for collecting human mobility traces. These are two university campuses (NCSU and KAIST), New York City, Disney World (Orland), and North Carolina state fair. 

network configuration: Garmin GPS 60CSx handheld receivers are used for data collection which are WAAS (Wide Area Augmentation System) capable with a position accuracy of better than three meters 95 percent of the time, in North America.

data collection methodology: The GPS receivers take reading of their current positions at every 10 seconds and record them into a daily track log.  

limitation: Occasionally, track information has discontinuity mainly when bearers move indoor where GPS signals cannot be received.

note: The Campus I traces are taken by 20 students. The participants in Campus I were randomly selected students who took a course in the computer science department. Every week, 2 or 3 randomly chosen students carried the GPS receivers for their daily regular activities. The Campus II traces are taken by 32 students who live in a campus dormitory. The New York City traces were obtained from 12 volunteers living in Manhattan or its vicinity. Most of the participants have offices in Manhattan. Their track logs contain relatively long distance travels because of their long commuting paths. Their means of travel include subway trains, buses and mostly walking. The State fair track logs were collected from 8 volunteers who visited a local state fair that includes many street arcades, small street food stands and showcases. The event was very popular and attended by more than one thousand people daily for two weeks. The site is completely outdoor and is smallest among all the sites. Each participant in the State fair scenario spent less than three hours in the site. The Disney World traces were obtained from nineteen volunteers who spent their thanksgiving or Christmas holidays in Disney World, Florida, USA. For our study, we use only the track logs from the inside of the theme parks. The participants mainly walked in the parks and occasionally rode trolleys.

• description: We collected daily GPS track logs from five different sites - two university campuses (NCSU and KAIST), New York City, Disney World (Orlando), and North Carolina state fair.
• measurement purpose: User Mobility Characterization, Routing Protocol for DTNs (Disruption Tolerant Networks), Positioning Systems, Human Behavior Modeling
• methodology: The GPS receivers take reading of their current positions at every 10 seconds and record them into a daily track log. All participants in the five scenarios are different individuals. The radius of each trace is a half of the maximum distance that a participant travels during a day.

• NCSU: Daily GPS track log collected from a university campus (NCSU), North Carolina, USA.

• configuration: The GPS receivers take reading of their current positions at every 10 seconds and record them into a daily track log. The participants in NCSU Campus were randomly selected students who took a course in the computer science department. Every week, 2 or 3 randomly chosen students carried the GPS receivers for their daily regular activities. Each file represents a daily trace from one participants. One participant can make one or more daily trace files. But we cannot tell which files come from the same person.
