Reporting dwell statistics in Second Life as a measure of engagement Traffic is a number allocated to each parcel which is based on the amount of residents who visited, and the time spent on that parcel out of their total time in world that day.

Every user gets a set number of traffic points to give out during the 24 hours between midnight and midnight. The user's points are then evenly divided between those parcels. So, if I was online for 1 hour and spent 20 minutes on resident A's parcel and 40 minutes on resident B's parcel, resident A would get 33% of my points and resident B would get 66%. Alternately, if I only spent 5 minutes online and spent all of it on resident A's land, they would receive all of my points.
