Walls are objects that pedestrians cannot cross. They define walls and obstacles that exist in the simulated space. Use these three markup shapes to draw walls on top of your drawing:

•  Wall — Use this to draw walls of complex shapes (for example, an exterior wall).
•  Rectangular Wall — Use this to draw rectangular areas that are not acceptable to pedestrians (for example, a workspace).
•  Circular Wall — Use circular wall to draw circular obstacles inside the simulated area (for example, columns, pools, fountains, and so on).

The  Target Line is used in all pedestrian models because it defines the place where pedestrians appear in the simulated space. You can also use the target line to draw the destination of the pedestrian’s movement and the pedestrian’s waiting location (but these can also be defined with nodes and points). Target line is also used when you simulate how people move from one level to another.

•  Service with Lines — Use this to define services with queues where pedestrians wait until the service becomes available. This element consists of individual queue line and service elements. Queues can be realized as either straight lines or serpentine queues (typically used in airport check-in areas).
•  Service with Area — Use this to define services with an electronic queue, where pedestrians wait in the office area adjacent to the service until the service becomes available. This element consists of individual polygon node and service elements.

With pedestrian Nodes, you can draw stairs and revolving doors. Nodes can also be used to graphically define the place where pedestrians appear in the simulated space, where pedestrians move to, and where pedestrians wait.

There are two markup shapes you can use to draw nodes in pedestrian models:

•  Rectangular node
•  Polygonal node

Use Polygonal node when your node has a complex shape. If your node is rectangular, use Rectangular node instead.

You can add  Attractors within a node. An Attractor allows you to control the location of pedestrians within a node. If the node defines the destination of the pedestrian movement (is referenced by PedGoTo), attractors define exact destination points inside the node. If the node defines the pedestrians waiting location (is referenced by PedWait), attractors define exact points where pedestrians will wait inside the node.

 Escalator Group. An animation shape for a group of parallel escalators implemented as individual elements. It consists of one or more Escalator elements. The Escalator element enables you to set the movement direction for a particular escalator in the group and to perform other tasks dynamically at runtime using the functions of the element (turn the escalator on or off, change its speed, and so on). To simulate how pedestrians are transported by escalators, insert the PedEscalator Pedestrian Library block into the flowchart.

 Elevator. An animation shape for an elevator used by pedestrians in pedestrian simulation models. To simulate how pedestrians are transported by an elevator, insert the PedElevator block into the flowchart.

 Pathway. A pathway is used to restrict pedestrian movement with a walking corridor. When moving along the pathway, pedestrians try to stay within the boundaries of the pathway. However, if the pathway is crowded, pedestrians can easily cross the pathway boundaries and walk nearby. Pathway boundaries do not act as walls. The pathway simply defines the path of travel. One of the most common uses of the pathway is to separate opposing pedestrian flows, such as in an underground passage.

 Density Map. Shows the density map with its Type property automatically set to Pedestrian. You will see that as pedestrians move in the simulated space, the layout is gradually colored. The color of each point in the space corresponds to the current density in that particular area. The density map is continuously repainted according to the actual values: if the density changes at any point, the color changes dynamically to reflect that change. In areas with zero density, the space remains unpainted.

 Ped Flow Statistics. This element collects statistics about pedestrians crossing the drawn section.
