Abstract

Systems and methods herein describe accessing a set of feature flags, a first feature flag in the set of feature flag describing vehicle navigation behavior on a routing graph, the routing graph representing the roadway, associating the set of feature flags with a vehicle, applying the associated set of feature flags to a graph traversal algorithm to generate a modified graph traversal algorithm, generating the route using the modified graph traversal algorithm; and transmitting instructions to the vehicle to begin executing the route.

1. A method for generating a route for an autonomous vehicle traversing a roadway, the method comprising:

accessing, using one or more processors, a set of feature flags, a first feature flag in the set of feature flags describing autonomous vehicle navigation behavior on a routing graph describing the roadway, and wherein the set of feature flags comprises a vehicle operator feature flag representing whether the autonomous vehicle is operated autonomously, the vehicle operator feature flag having a Boolean flag value;

associating the set of feature flags with the autonomous vehicle;

applying the associated set of feature flags to a graph traversal algorithm to generate a modified graph traversal algorithm;

generating the route using the modified graph traversal algorithm, the route comprising a single route for the autonomous vehicle based on autonomous vehicle constraints and roadway constraints; and

causing the autonomous vehicle to execute the route.

classifying a roadway element that can be traversed by the autonomous vehicle as a permitted maneuver.

4. The method of claim 1 , wherein the vehicle operator feature flag has a false Boolean value, the method further comprising:

classifying a roadway element that cannot be traversed by the autonomous vehicle as a forbidden maneuver; and

generating the route using the modified graph traversal algorithm, the generated route excluding the roadway element.

5. The method of claim 1 , wherein the set of feature flags comprises a weighted feature flag representing an importance of an aspect of vehicle navigation behavior, the weighted feature flag having an integer value.

6. The method of claim 1 , wherein associating the set of feature flags with the autonomous vehicle further comprises:

receiving, via an application programming interface, an instruction to associate the set of feature flags with the autonomous vehicle.

7. The method of claim 1 , wherein the roadway comprises roadway elements on a geographical map.

8. A system comprising:
