Abstract: Disclosed are performance metrics for evaluating the accuracy of a dynamic model in predicting the trajectory of ADV when simulating the behavior of the ADV under the control commands. The performance metrics may indicate the degree of similarity between the predicted trajectory of the dynamic model and the actual trajectory of the vehicle when applied with identical control commands. The performance metrics measure deviations of the predicted trajectory of the dynamic model from the actual trajectory based on the ground truths. The performance metrics may include cumulative or mean absolute trajectory error, end-pose difference (ED), two-sigma defect rate (?2?), the Hausdirff Distance (HAU), the longest common sub-sequence error (LCSS), or dynamic time warping (DTW). The two-sigma defect rate represents the ratio of the number of points with true location error falling out of the 2? range of the predicted location error over the total number of points in the trajectory.

Abstract: Systems, methods, and media for factoring localization uncertainty of an ADV into its planning and control process to increase the safety of the ADV. The uncertainty of the localization can be caused by sensor inaccuracy, map matching algorithm inaccuracy, and/or speed uncertainty. The localization uncertainty can have negative impact on trajectory planning and vehicle control.

Abstract: Example methods and systems for validation-based service request handling are described. In one example, a computer system may obtain, from a management entity, configuration information specifying a unicast service address associated with a service node capable of providing a network service. In response to detecting a service request from the virtualized computing instance, the computer system may generate a modified service request that (a) is destined for the unicast service address and (b) includes a validation identifier (ID) associated with the virtualized computing instance. The modified service request may be forwarded towards the service node to cause the service node to perform validation based on the validation ID to determine whether to provide the network service. In response to detecting a service response from the service node, the service response, or a modified service response, may be forwarded towards the virtualized computing instance.
