Abstract: Methods, systems, apparatuses, and computer program products are provided for enabling devices to determine the time zone in which they are located. A mobile device may receive location information from one or more sources. Based thereon, the current location of the mobile device may be determined in terms of latitude and longitude. The indication of the current location may be converted to an index value according to a Hilbert curve (or other space-filling curve), and the index value applied to a time zone index file to determine the local time zone. A time zone setting of the mobile device may be updated accordingly. Furthermore, “geofencing” may be used by the mobile device to detect movement towards and through a time zone boundary, leading to a new time zone determination being initiated.

Abstract: The controller of the present disclosure enables an autonomous vehicle to travel at increased speed in a high performance driving behavior region (HPDBR), such as when a likelihood of the autonomous vehicle driving off course or colliding with other vehicles and/or people at the work site is low. In some implementations, a controller of an autonomous vehicle may obtain autonomous vehicle position information. The controller may determine, based on the autonomous vehicle position information, that the autonomous vehicle is located within an HPDBR of an autonomous driving area. The controller may determine, based on determining that the autonomous vehicle is located within the HPDBR, whether an HPDBR-related risk exists. The controller may cause, based on determining whether an HPDBR-related risk exists, an autonomous vehicle speed control operation to be performed.
