Claim 0:
1. A method comprising: receiving, by one or more computing devices, sensor data identifying a plurality of potential sidewalk areas; filtering, by the one or more computing devices, the sensor data based on at least one of clearance width, slope or obstructions associated with each of the potential sidewalk areas to eliminate areas of the plurality of potential sidewalk areas that are unlikely to include a sidewalk; identifying, by the one or more computing devices, a plurality of pathways in the filtered potential sidewalk areas that are adjacent to a road in a vicinity of an autonomous vehicle; categorizing as a first sidewalk, by the one or more computing devices, a first pathway of the plurality of identified pathways adjacent to a first side of the road; categorizing as a second sidewalk, by the one or more computing devices, a second pathway of the plurality of identified pathways adjacent to a second side of the road; determining, by the one or more computing devices, results indicating whether a crosswalk exists between the first and second pathways of identified pathways; and operating, by the one or more computing devices, the autonomous vehicle based on the results.
