Question1

“Patterns of Life” analyses depend on recognizing repeating patterns of activities by individuals or groups. Describe up to six daily patterns of life by vehicles traveling through and within the park. Characterize the patterns by describing the kinds of vehicles participating, their spatial activities (where do they go?), their temporal activities (when does the pattern happen?), and provide a hypothesis of what the pattern represents (for example, if I drove to a coffee house every morning, but did not stay for long, you might hypothesize I’m getting coffee “to-go”). Please limit your answer to six images and 500 words.

1) Entrance Visitor Flow:

Cars of Type 1,2 and 3 usually enter the preserve park between 6AM to 5PM during day time, and they do not have strong preference for any specific entrance. Yet when they exit, there are obviously more cars taking exit 3, from 6AM all the way to 12PM.

2) Day Camper & Pass Only

“Day Campers” are those who enter and exit the park within one day with camping activities. These cars start entering the park from 5 AM and stop entering the park at 5PM. All of them leave the park at around 7 PM.

3) Day Visitor

“Day Visitors” are those who enter and exit park within one day without any camping activities, but have more checkpoints than just 2(enter and exit). “Pass Only” are those only have 2 checkpoints – enter and exit. Both of the two groups of cars enter and exit the park basically anytime. The Day Visitors might come for any reason: enter at 3 AM for sunrise, 3 PM for sunset or 9 PM to see the stars.

4) Overnight Camper

“Overnight” Campers are those stay in the park overnight with camping activities. They They usually enter the park from 6 AM to 5PM and leave the park the next day from 6AM to 0AM.

5) Overnight Visitor

“Overnight Visitors” are those who stay in the park overnight and have more checkpoints than only 2. The majority of them enter the park after 11 PM and leave the park within 2 hours, yet a few of them might come earlier and stay a bit longer, leave at about 8 AM next morning.

6) Ranger

Rangers are separated from visitors/campers. They are all “2P” cars and they usually start their journey in the park from “ranger-base” instead of any of the entrances. They start working anytime during the daytime which is 6AM to 5PM and end the work on the same day. But it sometimes happens that they need to work overnight and go back to ranger-base after 23:59PM.
