Abstract
Systems and methods for navigating a host vehicle are disclosed. In one implementation, a system includes a processor configured to receive from a camera onboard the host vehicle an image representative of an environment of the host vehicle. The image is provided to a trained system, which is configured to infer a presence of a curved road segment in the image, wherein the curved road segment is associated with a road on which the host vehicle is traveling. The processor is configured to receive at least one speed value for the host vehicle based on a proximity of the host vehicle to the curved road segment and based on at least one characteristic of the curved road segment represented in the image. The processor is configured to cause the host vehicle to take at least one navigational action based on the determined at least one speed value.
