  • GPS Global Positioning System
  • the utility of the PND is manifested primarily in its ability to determine a route between a start or current location and a destination, which can be input by a user of the computing device, by any of a wide variety of different methods, for example by postcode, street name and number, and previously stored well known, favourite or recently visited destinations.
  • the PND is enabled by software for computing a “best” or “optimum” route between the start and destination address locations from the map data.
  • a “best” or “optimum” route is determined on the basis of predetermined criteria and need not necessarily be the fastest or shortest route.
  • the selection of the route along which to guide the driver can be very sophisticated, and the selected route may take into account existing, predicted and dynamically and/or wirelessly received traffic and road information, historical information about road speeds, and the driver's own preferences for the factors determining road choice.
  • the device may continually monitor road and traffic conditions, and offer to or choose to change the route over which the remainder of the journey is to be made due to changed conditions.
  • Real time traffic monitoring systems based on various technologies (e.g. mobile phone calls, fixed cameras, GPS fleet tracking) are being used to identify traffic delays and to feed the information into notification systems.
  • the navigation device may typically be mounted on the dashboard of a vehicle, but may also be formed as part of an on-board computer of the vehicle or car radio.
  • the navigation device may also be (part of) a hand-held system, such as a PDA (Personal Navigation Device) a media player, a mobile phone or the like, and in these cases, the normal functionality of the hand-held system is extended by means of the installation of software on the device to perform both route calculation and navigation along a calculated route.

  • the user interacts with the navigation device to select the desired calculated route, optionally from a list of proposed routes.
  • the user may intervene in, or guide the route selection process, for example by specifying that certain routes, roads, locations or criteria are to be avoided or are mandatory for a particular journey.
  • the route calculation aspect of the PND forms one primary function provided, and the navigation along such a route is another primary function.
  • the PND provides visual and/or audible instructions to guide the user along a chosen route to the end of that route, that is the desired destination. It is usual for PNDs to display map information on-screen during the navigation, such information regularly being updated on-screen so that the map information displayed is representative of the current location of the device, and thus of the user or user's vehicle if the device is being used for in-car navigation.
  • An icon displayed on-screen typically denotes the current device location, and is centred with the map information of current and surrounding roads and other map features being also displayed. Additionally, navigation information may be displayed, optionally in a status bar above, below or to one side of the displayed map information, examples of navigation information including the distance to the next deviation from the current road required to be taken by the user, the nature of that deviation possibly being represented by a further icon suggestive of the particular type of deviation, for example a left or right turn.
  • the navigation function also determines the content, duration and timing of audible instructions by means of which the user can be guided along the route. As can be appreciated a simple instruction such as “turn left in 100 m” requires significant processing and analysis.

  • the device software would then calculate various routes and weigh more favourably those that include along their route the highest number of points of interest (known as POIs) tagged as being for example of scenic beauty, or, using stored information indicative of prevailing traffic conditions on particular roads, order the calculated routes in terms of a level of likely congestion or delay on account thereof.
  • POIs points of interest
  • Other POI-based and traffic information-based route calculation and navigation criteria are also possible.
  • route calculation and navigation functions are fundamental to the overall utility of PNDs, it is possible to use the device purely for information display, or “free-driving”, in which only map information relevant to the current device location is displayed, and in which no route has been calculated and no navigation is currently being performed by the device. Such a mode of operation is often applicable when the user already knows the route along which it is desired to travel and does not require navigation assistance.
  • map data does not generally include transient road alterations, such as may be caused by road works, carriageway reductions or alterations, or pedestrianization of roads previously mapped as vehicular thoroughfares.
  • map data files installed in new PNDs and navigation systems already tend to be at least a year or so out of date by the time the device or system is delivered to the end user.
  • MapShareTM technology in software provided on the device which affords the user the facility to identify a variety of corrections for immediate or subsequent transmission to validation, collation and/or other back-end, server-based processing at a centralized location. Transmissions of such map-specific, corrective information may be delivered by means of establishing a short-range wireless communication with a mobile telephone, usually using a Bluetooth® protocol thus enabling the device to transmit such information ultimately over a mobile telecommunications network.
  • Examples of the corrective information which may be stored and subsequently transmitted from the device are:
  • Street unblocking/blocking i.e. making a previously un-enterable street enterable and vice versa
  • one-way direction reversal street name data and property number/name data

  • GPS trace log data from devices (usually submitted by means of downloads from devices to a connected PC and thence over the internet to a back end processing facility of device/map data manufacturers) will typically contain only GPS data and a time stamp, or differential values for these characteristics from initial GPS and time readings.
  • vast amounts of GPS trace log data may be recorded, and require lengthy and resource-hungry analysis using known map-matching techniques to determine map errors.
  • This process can be dramatically accelerated by only processing GPS trace log data which has been flagged in the device during recordation thereof (again using map-matching techniques). This being the case, the post-processing is restricted to only flagged data, map errors can be confirmed, verified or rejected in a much quicker time frame. Such flagging might also usefully occur when any unexpected automatic route-re-planning is conducted by the device.

  • the device may either issue an immediate warning to the user, prompt the user to correct the map data by confirming that the access direction for the current street is incorrectly identified in the map data, or additionally or alternately, the device may automatically create correction data including location information specifying the street and other data identifying the fact that the map data specifies an incorrect access direction. It also possible for the device to determine that the current speed of travel along a particular road or stretch of road is greater than the speed restriction identified in map data for that road or stretch of road, and take appropriate automatic or prompt/response dependent corrective action.
