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.

Methodology for establishing time of response to map discrepancy detection event

The disclosed technology provides solutions for enriching map data with event information. In some aspects, the disclosed technology includes a process that includes steps for receiving a map query associated with the map for a user, aggregating one or more events that are associated with a respective location on a map, and processing the one or more events to generate one or more event clusters based on the map query. In some aspects, the process can further include steps for providing at least one of the one or more event clusters to the user. Systems and machine-readable media are also provided.

Spatial aggregation of autonomous vehicle feedback

The subject disclosure relates to ways to improve route duration calculations e.g., estimated time of arrival (ETA) approximations, by taking consideration of reroute probabilities along a given vehicle path. In some aspects, the disclosed technology encompasses a process including steps for identifying a route between a first destination to a second destination, determining a reroute likelihood associated with at least one AV maneuver along the route, and calculating an estimated time of arrival (ETA) based on the reroute likelihood associated with at least one AV maneuver. Systems and machine-readable media are also provided.

Estimating trip duration based on vehicle reroute probabilities

The disclosed technology provides solutions for detecting and localizing road signage, such as speed limit signs. A process of the disclosed technology can include steps for receiving a first set of sensor data comprising a signage feature, wherein the first set of sensor data is associated with a first location, receiving a second set of sensor data comprising the signage feature, wherein the second set of sensor data is associated with a second location, and determining a location of the signage feature based on the first location and the second location. Systems and machine-readable media are also provided.
