摘要： The technology relates to determining general weather conditions affecting the roadway around a vehicle, and how such conditions may impact driving and route planning for the vehicle when operating in an autonomous mode. For instance, the on-board sensor system may detect whether the road is generally icy as opposed to a small ice patch on a specific portion of the road surface (1702). The system may also evaluate specific driving actions taken by the vehicle and/or other nearby vehicles (1704, 1706, 1708, 1710). Based on such information, the vehicle's control system is able to use the resultant information to select an appropriate braking level or braking strategy (1714). As a result, the system can detect and respond to different levels of adverse weather conditions. The on-board computer system may share road condition information with nearby vehicles (1612, 1614) and with remote assistance (1604), so that it may be employed with broader fleet planning operations.
