  • Publication number: 20160356603
    Abstract: Some embodiments provide a map application that receives a starting location and a destination location. The application then identifies several different transit routes from the starting location to the destination location based on a set of transit preferences. Each transit route includes a set of transit legs each of which is serviced by a different transit line. In some embodiments, the application ranks the identified transit routes based on a set of criteria, and displays a representation of a highest ranked transit route over a portion of a map presentation along with a set of information about the displayed transit route.

  • Publication number: 20160356624
    Abstract: Some embodiments provide a mapping application that provides a first map browsing mode for displaying a map that emphasizes a first set of features in a map region. The mapping application also provides a second map browsing mode for displaying a map that de-emphasizes the first set of features while emphasizing a second set of transit-related features in the map region.

  • Publication number: 20160358471
    Abstract: Some embodiments provide a map application that displays a selectable user interface (UI) item for a transit station, a representation of which, is displayed over a presentation of a portion of a map of an area. Upon selection of the UI item, the map application of some embodiments provides a graphical user interface (GUI) that includes a first set of information about the transit station, and a second set of information about departure schedules of several different transit lines from the transit station.

  • Publication number: 20160356617
    Abstract: Some embodiments provide a map application that identifies several different transit routes from a starting location to a destination location. Each identified transit route includes one or more transit legs that are serviced by different transit vehicles of different transit lines. The map application also identifies a set of incidents that are associated with one or more transit legs of one or more of the identified transit routes. The map application of some embodiments then ranks the transit routes based on a set of criteria and the identified set of incidents. The map application displays, in a display area, a representation of a highest ranked transit route over a portion of a map presentation.

  • Publication number: 20160358469
    Abstract: Some embodiments provide a map application that identifies a transit route between a starting location and a destination. The transit route, in some embodiments, includes a set of transit legs that each is serviced by transit vehicles of a transit line. The map application of some embodiments, after identifying the transit route, categorizes each transit line of the transit route as one of a high frequency transit line and a low frequency transit line. The map application displays the departure schedules of high frequency transit lines in a first manner, while the map application displays the departure schedules of low frequency transit lines in a second different manner.

  • Publication number: 20160356613
    Abstract: Some embodiments provide a map application that identifies a transit route that includes one or more transit legs between a starting location and a destination location. In response to a request to start navigating the identified transit route, the map application of some embodiments provides a first display area for displaying a set of navigation instructions, each of which describes a transit maneuver that is associated with a transit leg of the transit route. The map application also provides a second display area for displaying a map region presentation associated with the navigation instruction that is displayed in the first display area.

  • Publication number: 20160294545
    Abstract: A method and system are provided for synchronizing local clocks more quickly in a telecommunication network using IEEE 1588. A network element that receives timing signals from one or more possible parent clocks considers a measure of the reliability of the timing signals contained in Announce messages from the parent clock or clocks. The clock uses this reliability information in selecting one of the possible parent clock or clocks to use as the actual parent clock. Once the selection is made, the clock adjusts the filtering characteristics applied to timing signals received from the selected parent clock. The adjustments reflect how confident the parent clock is as to how stable the timing information, it provides has become. If the indication of reliability contained in Announce messages received from the parent clock indicates that the timing information is not very reliable, then a high filter bandwidth is used in filtering the timing signals.

  • Publication number: 20160094335
    Abstract: An intermediate clock, either a boundary clock or a transparent clock, may have to adjust its local clock to match that of a grandmaster clock. If such adjustment is frequent or large, then the intermediate clock may not have much confidence in the reliability of the timing information it passes to a downstream clock in an IEEE 1588 Announce message even if the quality of its local clock is high. The intermediate clock determines a measure of the reliability of its timing information. The intermediate clock inserts an indication of the reliability of the timing information in a transmitted IEEE 1588 Announce message. The intermediate clock may consider an indication of reliability found in an Announce message it receives when inserting an indication of the reliability of timing information into an Announce message which it transmits.
