1. A method of analyzing drainage of a transportation pathway, the method comprising:
obtaining, using an imaging device of an inspection system, image data reproducible as a plurality of images of the transportation pathway, each of the plurality of images being reproducible as an image of a portion of the transportation pathway, each portion having an associated location along a length of the transportation pathway;
analyzing, using one or more processors of the inspection system, the image data to identify a presence of standing water in each of the plurality of images of the transportation pathway;
determining, based on the analyzing the image data, a plurality of metrics being indicative of a drainage conditions of the transportation pathway; and
generating a graph using at least a portion of the determined plurality of metrics for visually illustrating the drainage condition at each of the associated locations.
