Question4
The top 3 suspicious patterns, as far as I am concerned, are:
1. No.of Stops vs Overall time spent
Those 3 Car-IDs that stayed in the park for extremely long are very suspicious. For other cars, their car-ID is generated whenever then enter the park at entrance gate. Yet these 3 Car-IDs have more than 2 records of entrance gates, which means their car-IDs are not per-trip generated. This is not reasonable.
2. "Gate" Visitors at night
Gate is gate type for rangers only. Any non-ranger car that accessed this gate type is considered suspicious. Especially when these records happen at late night, it is even worse.
3. "ranger-stop" Visitors at night
Ranger-stop is also for rangers only. Same reason as why Gate visitors at night are suspicious.
