Depending on the agent they varying in speed, energy levels and objective or goals. Landscape agents are basically solitude seeking, They traverse the canyon minimizing encounters with other agents. These agents will pass other agents along the way, stop at scenic lookouts only when there are less that four other recreators present. These behaviors coincide with the desired benefits extracted earlier in the survey. Seeking physical exercise, avoiding crowds and enjoying nature are strongly correlated benefits of this group of recreators.
All agents keep track of visual and physical encounters along the way.
A hiker s visual encounter for example is from along the hiking trail. Hikers in front of the evaluating agent are summarized for each cell that agent is currently in. At the same time each agent is evaluating biker and jeep agent using other trails in the database. All agents detect explicit locations of other agents and determine whether they are visible or not. Each agent then has a record of where and how many visual encounters it has with other agents as it is moving through the landscape over time.
