Data Discription

Entry gates are positioned at the Preserve entrances. Each vehicle receives an entry ticket at the gate and is assigned a vehicle class; the entry is recorded. The entry ticket contains an RF-tag that enables the Preserve sensors to pick up the passage of a vehicle through the Preserve. Each vehicle surrenders their entry ticket when exiting the Preserve and the exit is recorded.When vehicles enter the Preserve, they must proceed through a gate and obtain a pass.

Details Discription

1. Entrances: All vehicles pass through an Entrance when entering or leaving the Preserve.

2. General-gates: All vehicles may pass through these gates. These sensors provide valuable information for the Preserve Rangers trying to understand the flow of traffic through the Preserve.

3. Gates: These are gates that prevent general traffic from passing. Preserve Ranger vehicles have tags that allow them to pass through these gates to inspect or perform work on the roadway beyond.

4. Ranger-stops: These sensors represent working areas for the Rangers, so you will often see a Ranger-stop sensor at the end of a road managed by a Gate. Some Ranger-stops are in other locations, however, so these sensors record all traffic passing by.

5. Camping: These sensors record visitors to the Preserve camping areas. Visitors pass by these entering and exiting a campground.

Step by Step Discription

Extract the car sequences

The most essentail step for data preparation is to extract the car sequences which helps to summary the life patterns. This step is conducted in JMP with the function[Col Rank(Timestamp,car-id)]
