1. Q1 Answer - Usual Daily Patterns
1.1. Different Types of Cars Are Grouped Into 3 Categories
- Category 1: 4 or more axle truck, 3 axle truck and 2 axle bus are possibly transportation vehicles. The chart in the left shows that the number of them remains relatively flat and constant respectively throughout the day. Also, the chart in the left does not show these 3 types of cars on the row of sensor – camping, meaning these types of cars never go to camping areas. Therefore, these 3 types of cars are possibly transportation vehicles.
- Category 2: 2 axle car, 2 axle truck and 3 axle truck are visitors' vehicles and camp in the preserve. The chart in the left shows that the number of these 3 types of cars are generally active from 5AM to 7AM with peak hour from 8AM to 5PM. Also, the camping row of the chart in the right not only presents the number of these 3 types of cars over time, but also shows that 2 axle truck does overnight camping and 2 axle car and 3 axle truck does daytime camping.
- Category 3: 2P car is no doubt the ranger vehicle which is active from 6AM to 11PM and there is totally no 2P cars during 3AM to 6AM.
2. Q2 Answer - Usual Longer Period Patterns
3. Q3 Answer - Unusual Patterns
3.1. Weekend Late Night Camper Repeating The Same Route for 15 Times
- By filtering out the number of route count from 10-16, routes with route count 15 and 16 appears on the chat in the left. By viewing the data, these 2 routes are traveled by a 2 axle truck, car id: 20154519024544-322. Except the first time, in the rest of 15 times when it comes to the preserve, it follows exactly the same route and leaves the preserve either at Sunday midnight or in early Monday morning.

3.3. Unauthorized Access to Ranger-stops by 2 axle truck
- Ranger-stop 1 is only accessible for rangers, however, after filtering 2 axle car, the route shows that there is a path between entrance 1 and ranger-stop 1.By viewing the original data, there are 6 (cad id are as shown in the chart in the right) 2 axle cars which entered the preserve on the same day, 10 Jul 2015 follows the same path, and the path is actually round-trip path, meaning they went to ranger-stop 1 with clear purpose and intention.
