Car
(x, y, xdim=80, ydim=40, angle=0.0, vel=0.0, max_vel=5, mass=100.0, dynamics_model='kinematic', destination=None, trajectory=None)[source]¶ Represents a point-model car.
Parameters: - x (float) – Starting x coordinate of car’s center
- y (float) – Starting y coordinate of car’s center
- angle (float) – Starting angle of car in world space
- vel (float) – Starting velocity of car
-
vel
¶ float – Forwards velocity of car
-
max_vel
¶ float – Maximum allowable velocity of this carst
-
xdim
¶ float – Length of car
-
ydim
¶ float – Width of car

Pedestrian
(x, y, radius=12, angle=0.0, vel=0.0, acc=0.0, max_vel=2.0, mass=100.0, dynamics_model='point')[source]¶ Represents a pedestrian as a circle
Parameters: - x (float) – Center x coordinate
- y (float) – Center y coordinate
- radius (float) – Size of the pedestrian
- angle (float) – Initial orientation, in degrees
- vel (float) – Initial velocity
- max_vel (float) – Maximum velocity
- mass (float) – Mass of pedestrian
Terrain¶
Lanes¶

Lane
(x=0, y=0, xdim=0, ydim=0, angle=0.0, angle_deg=0, points=[], curvature=0, inner_r=0, outer_r=0)[source]¶ Represents a lane of road. Lanes have directionality, so cars should drive in the right direction. Default construction creates a rectangular block.
Parameters: - x (float) – Upper left x coordinate of the lane block
- y (float) – Upper left y coordinate of the lane block
- xdim (float) – Width of the lane block
- ydim (float) – Height of the lane block
- ; float (angle) – In degrees, the rotation of the lane block. The correct direction of travel along this lane.
- points (list) – List of XY coordinates specifying edge points of a polygon. If specified, lane will be constructed as a polygon.
- curvature (list) – If specified, generates a curved road segment with this arc angle, centered at x, y, and with inner and outer radii
- outer_r (inner_r,) – Use with curvature argument to generated curved road segment.
Sidewalks¶
-
class

Sidewalk
(x, y, xdim, ydim, angle=0.0, angle_deg=0, points=[])[source]¶ Represents a block of sidewalk. Passable for pedestrians, not for cars
Parameters: - x (float) – Upper left x coordinate of the sidewalk block
- y (float) – Upper left y coordinate of the sidewalk block
- xdim (float) – Width of the sidewalk block
- ydim (float) – Height of the sidewalk block
- points (list) – If specified, constructs sidewalk as polygon
-
generate_man
(man_type=<class 'gym_urbandriving.assets.pedestrian.Pedestrian'>)[source]¶ Generates a man on the sidewalk
Returns: Generated Pedestrian object Return type: Pedestrian
Streets¶
-
class
gym_urbandriving.assets.
Street
(x, y, xdim, ydim, angle=0, points=[])[source]¶ Represents a block of street. Passable for cars and pedestrians. Does not have directionality associated with it, so use this for the middle of an intersection
Parameters: - x (float) – Upper left x coordinate of the street block
- y (float) – Upper left y coordinate of the street block
- xdim (float) – Width of the street block
- ydim (float) – Height of the street block
- points – If specified, constructs this shape as a polygon
