1. A system for sparse map autonomous navigation of a vehicle along a road segment, the system comprising:

  • at least one processor programmed to;

    receive a sparse map of the road segment, wherein the sparse map has a data density of no more than 1 megabyte per kilometer and the sparse map includes a three-dimensional polynomial representation of a target trajectory for the vehicle to traverse along the road segment;

    receive from a camera, at least one image representative of an environment of the vehicle;

    analyze the sparse map and the at least one image received from the camera; and

    determine an autonomous steering action for the vehicle based on the analysis of the sparse map and the at least one image received from the camera.
