This document describes techniques and systems for indirectly verifying speed limits based on contextual information for autonomous and semi-autonomous driving systems. In addition to a camera system, the described techniques and systems use other sensors and secondary factors to improve the accuracy and credibility of detecting published speed limits. For example, a camera system captures an image or other data directly indicative of a speed limit. Contextual information of the road or contextual information of nearby vehicles is also obtained and used to determine at least one indirect indication of the speed limit. Composite speed limits are identified by applying respective weights to direct and indirect indications of speed limits. Systems and techniques are described to enable control of a vehicle based on a composite speed limit. In this manner, the described systems and techniques may verify speed limits to make autonomous and semi-autonomous driving systems safer.

    本文档描述了用于基于自主和半自主驾驶系统的情境信息间接验证速度限制的技术和系统。除了相机系统之外,所描述的技术和系统还使用其他传感器和次级因素来提高检测发布的速度限制的准确度和可信度。例如,相机系统捕获直接指示速度限制的图像或其他数据。还获得道路的情境信息或附近交通工具的情境信息并将其用于确定对速度限制的至少一个间接指示。通过将相应的权重应用于对速度限制的直接指示和间接指示来标识复合速度限制。所描述的系统和技术从而能够基于复合速度限制来控制交通工具。以此方式,所描述的系统和技术可以验证速度限制,以使自主和半自主驾驶系统更安全。
