Aspects of the disclosure relate to safely navigating crosswalks by responding to potentially occluded objects in such crosswalks. For example, a vehicle approaches a crosswalk and the vehicle's one more computing devices may generate a set of samples corresponding to locations in the crosswalk. Sensor data is periodically received by the one or more computing devices. For each given sample of the set of samples a probability value indicative of a probability of sample being occluded is set to an initial value by the one or more computing devices. As the vehicle approaches the crosswalk, probability values for the given sample are periodically adjusted by the one or more computing devices based on the periodically received sensor data. The speed of the vehicle then changed by the one or more computing devices based upon a determination that a sample of the set of samples has met the threshold value.
