Parameter Type Range Description
on_track boolean True|False
The vehicle is off track (False) if the front of the vehicle is outside of
the white lines, otherwise, it's on track (True).
x float [0,inf] Location of the vehicle along the x-axis, starting from 0.
y float [0,inf] Location of the vehicle along the y-axis, starting from 0.
distance_from_center float [0,track_width/2]
Displacement from the center line of the track as defined
by waypoints.
car_orientation float [-π, π]
Orientation of the vehicle around its z-axis as measured against the x-
axis in radians. If the vehicle starts in the direction of the x-axis of the
track, the car_orientation is 0 at the starting point.
progress float [0,1] Percentage of track completed.
steps int [0,n] Number of steps completed.
throttle float [0,1]
Vehicle's speed. 0 indicates stopped and 1 means at the maximum

track_width float [0,inf] Track width.
waypoint (float,float) (x,y) A coorindate of (x, y) defining a point on the track.
waypoints list [(x,y), …] An ordered list of waypoints.
closest_waypoint int
[0, number of
waypoints -1]
The zero-based index of the closest waypoint given the
vehicle's x and y positions as measured by the Euclidean distance. It
can be in front of the vehicle or behind it.
