  "abstract": "Travel data may be gathered and published on a global map for use by various entities. The travel data may be captured by one or more vehicle computing devices, such as those associated with the operation and/or control of a vehicle. The vehicle computing devices may receive input from one or more sensors, and may identify and/or classify an event and/or areas of interest based on the input. The vehicle computing devices may then send travel data to the global map server for publication. Additionally or alternatively, the travel data may be captured by one or more user devices. The user devices may be configured to receive travel data, such as via a user interface, and to send the travel data to the global map server for publication. The global map server may consolidate and publish the travel data on a global map.",

    "8. The method of claim 6, further comprising: identifying a subscriber to a global map service; and determining a subscription level of the subscriber, wherein publishing the derived information is based at least in part on the subscription level.",
    "9. The method of claim 6, further comprising assigning a confidence level to the travel data, wherein the incorporating the event, the location, and the classification into the global map is based at least in part on the confidence level being at or above a threshold confidence level.",
    "10. The method of claim 6, wherein the vehicle comprises a first vehicle, and the method further comprises: assigning a confidence level to the classification; receiving, at the global map server, second travel data from a second vehicle, wherein the second travel data corresponds to the event; associating the second travel data with the event; and increasing the confidence level based at least in part on the second travel data.",
    "11. The method of claim 6, wherein the travel data further comprises text describing the event, and the method further comprises: performing text recognition on the text; removing sensitive data from the text; associating the text with the global map; and publishing the text.",
    "12. The method of claim 6, wherein the travel data further comprises an image of the event and the method further comprises removing sensitive data from the image prior to publication of the global map, wherein the sensitive data comprises at least one of: a license plate number, a license plate issuing authority, a face of a person in the image, or a human form.",
    "13. The method of claim 6, wherein the vehicle comprises a first vehicle, and the method further comprises: receiving, at the global map server and from a second vehicle, an image corresponding to the event; and incorporating the image into the global map, wherein determining the derived information comprises selecting the image.",
    "14. The method of claim 6, wherein the travel data comprises first travel data received from a first vehicle, and the method further comprises: receiving, at the global map server, second travel data from a second vehicle, wherein the second travel data corresponds to the event; and associating the second travel data with the event, wherein determining the derived information comprises selecting at least a portion of the second travel data.",

  "description_excerpt": "Vehicular and other transportation methods can be impaired due to various events, such as accidents and traffic. Vehicle operators are often caught unaware of, and thus are affected by, these events. Sometimes, the vehicles controlled by the vehicle operators may further compound the effects of an event. For example, a driver or system operating a vehicle may not be aware of an accident on a roadway. The driver or system may operate the vehicle on the roadway, and may be slowed down or stopped, thereby adding to the congestion caused by the accident.\n\nThe detailed description is described with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The same reference numbers in different figures indicate similar or identical items.\n\nFIG. 1 is an example travel data collection and publication system.\n\nFIG. 2 is an example environment in which a vehicle may collect travel data in a travel data collection and publication system.\n\nFIG. 3 is a block diagram that illustrates select components of an example global map server device used for travel data collection and publication.\n\nFIG. 4 is an example global map generated in a travel data collection and publication system.\n\nFIG. 5 is a flow diagram of an illustrative process for gathering and publishing travel data.\n\nFIG. 6 is a flow diagram of another illustrative process for gathering and publishing travel data.\n\nFIG. 7 is a flow diagram of yet another illustrative process for gathering and publishing travel data.",
