Data driven map updating system for autonomous driving vehicles

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

• performing an analysis on driving statistics of a plurality of vehicles, wherein the driving statistics were collected from the plurality of vehicles driving on a lane of a road section;
• determining a first drivable area of the lane of the road section based on the analysis of the driving statistics, including calculating a boundary box surrounding each of a plurality of vehicles driving through the lane based on a physical dimension of the vehicle, and calculating an individual drivable area for the vehicle based on a moving curve of the boundary box;
• comparing the first drivable area with a second drivable area associated with the lane of the road section to determine whether the first drivable area is different than the second drivable area obtained from a map, wherein the second drivable area is determined based on map data of the map;
• and
• in response to determining that the first drivable area is different than the second drivable area, updating the map based on a difference between the first drivable area and the second drivable area, wherein the updated map is utilized subsequently to plan a path on within the lane of the road section to drive an autonomous driving vehicle (ADV).
