    Abstract: A system and method for identifying navigational hazards is disclosed. In some examples, the system can be included in, or the method can be performed by, a vehicle. One or more sensors included in the vehicle can gather perception data related to potentially dangerous driving conditions, such as blind corners, reckless drivers, accidents, and other hazards. The data can be associated with the location at which it was collected to predict future hazardous conditions at the same location. In some examples, a navigational system can use the data to determine the relative safety of one or more routes for driving to a destination. In some examples, a fully or partially autonomous vehicle can modify its driving behavior based on the relative safety of its location. Modifying driving behavior can include, for example, changing a top speed, a following distance, and conditions for changing lanes. In some examples, data from a plurality of vehicles can be uploaded to a remote server configured to model location-based danger. The model can be downloaded by one or more vehicles.

    Abstract: Systems and methods relating to determining a position or orientation of a vehicle are disclosed. A landmark is identified using sensor data presented by one or more sensors included with the vehicle. The landmark is identified using map data relating to an approximate location of the vehicle in a world coordinate system. A position or orientation of the vehicle relative to the landmark is determined. A position or orientation of the landmark relative to the world coordinate system is determined. Using the determined position or orientation of the vehicle relative to the landmark and the determined position or orientation of the landmark relative to the world coordinate system, a position or orientation of the vehicle relative to the world coordinate system is determined.
