the left diagram well demonstrates that there are peak and off-peak periods in terms of traffic flow in the nature reserve. It is clear that there are much more traffic during months of June, July and August and the traffic load dropped significantly after September.

Quarterly Pattern

Q1 Pattern: Q1 is the least popular season as the traffic only takes up 5.6% of the overall traffic. The routes in Q1 are quite short and a relative big portion of the traffic has routes of from one entrance to another entrance directly or only going through one gate, which can be assumed that these car ids are just using as the preserve as a convenient transportation option, in stead of actually visiting the preserve. There is almost no camping activities in Q1. In Q1, the traffic focuses on: Entrance4--Generalgate5--Generalgate2--Rangerstop0--Rangerstop2--Generalgate1 Entrance1--Generalgate7--Generalgate4 Entrance3--Generalgate1--Rangerstop2--Rangerstop0 Entrance2--Generalgate2--Rangerstop0--Rangerstop2 Entrance0--Generalgate1--Rangerstop2--Rangerstop0	Q2 Pattern: Q2 is a reasonably popular season and the traffic becomes much more compared to Q1 and the traffic routes are much longer and diverse.
