Systems and methods for automatically generating map validation tests
Systems and methods are provided for validating a map via automatic test generation for multiple test route subsections. Autonomous vehicles required accurate maps. As such, new maps may be added and/or maps map be updated frequently. Verifying these maps requires testing. Maps may be validated via automatic test generation by obtaining route information identifying a route in the map for an autonomous vehicle. The route may be segmented into multiple test route subsections. Features corresponding to one or more of the test route subsections may be identified. One or more validation tests corresponding to the test route subsections may be generated based on a simulated autonomous vehicle traversing the one or more road features. For example, multiple validation tests for corresponding test route subsections may be generated and executed in parallel.
1. A system for validating a map, the system comprising:

segment the route into multiple test route subsections according to the road feature;
automatically generate one or more validation tests corresponding to at least one of the multiple test route subsections based on a simulated autonomous vehicle traversing the road feature;
execute the one or more validation tests of the autonomous vehicle traversing the road feature to analyze traversability of the road feature by the autonomous vehicle; and
upon detecting a road feature is not traversable, modify software of the autonomous vehicle to achieve traversability of the road feature.
