1. A method for controlling an autonomous construction vehicle, comprising:
defining a boundary of a construction site;
identifying a longest edge of the boundary;
defining path orientation for the autonomous construction vehicle that is parallel to the longest edge of the boundary;
defining a start point for the autonomous construction vehicle;
defining a maneuver area for the autonomous construction vehicle based on the boundary and specifications of the autonomous construction vehicle;
defining a path for the autonomous construction vehicle to navigate the construction site, wherein the path is oriented according to the path orientation, including:
defining a first path portion starting at the start point and extending in a direction corresponding with the path orientation, and
defining a maneuver path in the maneuver area;
automatically creating a site plan indicating the boundary, path, start point, and maneuver area; and
controlling the operation of the autonomous construction vehicle based on the site plan.
