Pedestrian

To incorporate pedestrians using the Simulated Pedestrian model into simulation, we introduce additional attribute tags. Simulated Pedestrians (SP) navigate using behaviour trees based on a .btree file specified by the btree tag. The agent type tag gs=pedestrian is still used for Simulated Pedestrians, but the sub-type tag btype=SP must also be included. The only path information required for SP agents is a destination node referenced by the destination tag. For example, if the destination node has the tag name=sp_dest then an SP agent can use it as a destination point by including destination=sp_dest in its attribute tags.

Simulated Pedestrian Node

<node id='-2' lat='43.4777' lon='-80.5197'>
    <tag k='gs' v='pedestrian' />
    <tag k='name' v='pedestrian_1' />
    <tag k='btype' v='SP' />
    <tag k='btree' v='walk.btree' />
    <tag k='destination' v='ped_1_dest' />
</node>

Destination Node

<node id='-3' lat='43.4782' lon='-80.5201'>
    <tag k='gs' v='location' />
    <tag k='name' v='ped_1_dest' />
</node>

Pedestrian attributes:

k	v	description
gs*	'pedestrian'	GS role key
name*	string	A name for the Agent
btype**	string	SP for Simulated Pedestrians, TP for speed profile based pedestrians
btree**	string	Relative reference to the SP agent's behaviour tree file
destination**	string	Name attribute of the SP agent's destination node
speed	float (km/h)	Pedestrian standard target speed
yaw	int (deg)	Pedestrian standard orientation
usespeedprofile	bool (yes/no)	If yes, when assigned to a path a pedestrian will follow the speed profile from the path. Otherwise, the pedestrian will follow the path with its standard target speed.
model	string	A reference to a pedestrian model to be used in simulation

** Required tags for SP agents in addition to the general required tags for all pedestrian agents

Trajectory and path pedestrians

Trajectory pedestrians (TP) behave the same way as Trajectory vehicles (TV). Path pedestrians (PP) behave the same way as path vehicles (TV).
