A method that utilizes high-definition street level images provided by a network of stationary traffic cameras to identify potential hazards or concerns located beyond the range of vehicle mounted devices, and to provide an advanced warning or to take some other remedial action in response thereto. In one embodiment, the method uses multiple items taken from the street level images to corroborate a potential concern before saving that concern to a concern profile where the concern is linked or otherwise associated with a particular geographic zone. By taking remedial actions well in advance of a potential concern, the method provides more opportunity to adjust or otherwise address the potential concern, which can be particularly advantageous when the host vehicle is being operated in an automated driving mode.
