    摘要： An autonomous vehicle configured for active sensing may also be configured to weigh expected information gains from active-sensing actions against risk costs associated with the active-sensing actions. An example method involves: (a) receiving information from one or more sensors of an autonomous vehicle, (b) determining a risk-cost framework that indicates risk costs across a range of degrees to which an active-sensing action can be performed, wherein the active-sensing action comprises an action that is performable by the autonomous vehicle to potentially improve the information upon which at least one of the control processes for the autonomous vehicle is based, (c) determining an information-improvement expectation framework across the range of degrees to which the active-sensing action can be performed, and (d) applying the risk-cost framework and the information-improvement expectation framework to determine a degree to which the active-sensing action should be performed.

    摘要： Methods and apparatus are disclosed for providing information about road features. A server can receive reports from information sources associated with a road feature that can include a road intersection. Each report can include source data obtained at a respective time. The source data from the reports can be stored at the server. The server can construct a phase map, where the phase map is configured to represent a status of the road feature at one or more times. The server can receive an information request related to the road feature at a specified time. In response to the information request, the server can generate an information response including a prediction of a status related to the road feature at the specified time. The prediction can be provided by the phase map and is based on information request. The information response can be sent from the server.
