Blocks used to simulate passengers flow in AnyLogic.

No.	Symbol	Name	Introduction
1		PedSource	Generates pedestrians. It is usually used as a starting point of the pedestrian flow.
2		PedSink	Disposes pedestrians. It is usually used as an end point of the pedestrian flow.
3		PedGoTo	Causes pedestrians to go to the specified target.
4		PedService	Simulates how pedestrians are serviced in services.
5		PedWait	Causes pedestrians to wait for a specified time in a specified location.
6		PedSelectOutput	Routes the incoming pedestrians to one of the five output ports depending on specified ratios or conditions.
7		PedEnter	Places pedestrians into the simulated environment.
8		PedExit	Removes pedestrians from the simulated environment.
