Abstract: A map database stores data describing a set of connected roadways, each having one or more lanes. A coverage system selects lanes from the map database along which AVs can stop, such as parking lanes. The coverage system generates buffer regions for each of the stopping lanes, where each buffer region includes an area within a given distance of the respective lane. The coverage system combines the buffer regions to generate a coverage area, and provides a display of the coverage area overlayed over a map of roads corresponding to the coverage area.

Abstract: A methodology is described for determining a time for responding to an initial encounter by a vehicle with a map error in a map segment, wherein the initial encounter is detected by a detector. A method includes identifying an error type associated with the map error, wherein the error type is one of a first error type and a second error type; determining at least one additional factor associated with the initial encounter; determining a response time for the map error based on the error type and the at least one additional factor; and initiating a mitigating action in response to the initial encounter within the response time, wherein the response time comprises an amount of time from the initial encounter with the map error to a time at which a mitigating action should be taken.

Abstract: A ride evaluation platform can evaluate ride services provided by AVs to users, e.g., to determine whether the users are satisfied with the rider services so that the users will request more ride services. The ride evaluation platform may identify and classify operational behaviors of an AV based on a record of the AV's operation for providing a ride service. The ride evaluation platforms can further detect defects in the ride service based on the classifications of operational behaviors of AVs, user expressions that indicate one or more user sentiments towards the ride service, one or more conditions of an environment in which the AV operated for providing the ride service, or some combination thereof. The ride evaluation platform may determine a score for the ride service based on the defects. The score may indicate a likelihood of the user would request another ride service provided by an AV.

Abstract: Service disruption prevention through chokepoint identification and monitoring is disclosed. The present disclosure seeks to prevent (or drastically reduce the probability) mass vehicle recovery events due to fragile portions of the map. Choke points are identified by iterating through the lane segments of a map and analyzing the effect of their removal on the service area. Once identified, tooling is used to actively monitor chokepoints using a hybrid polygon with high granularity. Down and upstream effects also can be determined. Based on the monitoring of lane segments and/or areas, location connectivity can be estimated and a map fragility calculated therefrom. If map fragility reaches a critical state, one or more areas can be cut off from the service area.

Abstract: Service disruption prevention through monitoring dynamic geofencing is disclosed. The present disclosure seeks to prevent (or drastically reduce the probability) mass vehicle recovery events due to fragile portions of the map. Tooling is used to actively monitor chokepoints and new avoidance areas. Comprised by the operational design domain (ODD), geofences are actively changed in response to the state of the chokepoints and avoidance areas. Varying states can be assigned to a plurality of geofences within the ODD, for example, if a geofence reaches a critical state, one or more areas can be cut off from the ODD.

Abstract: A map database stores data describing a set of connected roads each having one or more lanes, each having one or more lanes. The map database further stores data describing at an avoidance area comprising an area in the map database that an autonomous vehicle (AV) avoids traversing. A routability system determines at least one lane that can be accessed by the AV if the AV traverses the avoidance area, and generates a restored coverage area corresponding to the at least one lane. The restored coverage area corresponds to an area of restored coverage provided by the AV traversing the avoidance area. The routability system computes a score based on the restored coverage area, the score indicating an impact of restoring access by the AV to the avoidance area.

Abstract: A methodology for establishing a frequency for reviewing of a map segment, in which encounters by a vehicle with a map error in the map segment are detected using at least one detector, is described. A method includes determining a time to next encounter (TTNE) for the map segment, the TTNE comprising a time until a next encounter with the map segment is expected to occur for a targeted quartile; determining a recall rate for the at least one detector, wherein the recall rate comprises a percentage of total encounters with the map error that are accurately detected by the at least one detector; and establishing a review frequency for the map segment based on the TTNE and the recall rate. A review ticket requiring manual review of the map segment is scheduled to be issued in accordance with the established review frequency.
