  • Device data 78 from N mobile devices 100 is obtained by the notification system 80 at 200, which data 78 is then stored in the traffic database 82.
  • device data 78 is obtained from mobile devices 100A, 100B, 100C, 100D, and 100E.
  • the device data 78 is then organized based on the zone from which it originates and the traffic database is updated. For example, the device data 78 from mobile devices 100B-100E would be grouped into one zone, whereas the device data 78 from mobile device 100A would be grouped into another zone.
  • the device data 78 may be stored according to the corresponding mobile device 100 or may instead be stored according to the current zone. In either case, the device data 78 should be time stamped such that a mobile device's movements can be tracked between snapshots of data and such that previous notifications and progress of that mobile device 100 is known. Also, movements of mobile devices 100 from one zone to another should be tracked. In this way, as the mobile device 100 moves progressively closer to a congested zone 2, the notifications may be modified to more intelligently redirect the mobile device 100. For example, a mobile device 100 that is 20 km away from the congested zone 2 may receive a different, less urgent warning, than a mobile device 100 that is 5 km away from the congested zone 2 or may be given a different suggestion for an alternative route. The combination of location and speed information, tracked over time can thus allow the notification system 80 to provide a cascade of notifications 84 according to the mobile device's location with respect to the congested zone 2.
  • the device data 78, thus grouped can then be used to perform a notification preparation routine at 204, for each zone at an applicable time.
  • the routine 204 determines the speed at which each mobile device 100 and, according to predetermined (or user defined) criteria, whether or not such speed is "normal” (as opposed to an anomaly representing traffic congestion) given the location, time of day, etc.
  • a criterion such as "Is speed ⁇ X km/h" can be used to determine the presence of traffic congestion whereby the device data 78 for vehicles 10 having a vehicle speed less than the threshold X are selected and can be used in determining traffic congestion.
  • vehicles 10B, 10C, and 10D are, in the snapshot shown, travelling at a relatively low rate of speed whereas vehicle 10E is travelling at a relatively higher or "normal" rate of speed.
  • the device data 78 for vehicles 10B, 10C, and 10D would be chosen in step 206 whereas the device data 78 for vehicle 10E would be ignored.
  • Other criteria such as empirically derived information can be used to determine what constitutes "normal" traffic. For example, rush hour traffic on certain routes may experience different traffic flow than the same route at other times during the day.
  • the notification system 80 may then determine if a predetermined number of mobile devices 100 have met the criteria applied during step 206 (e.g. according to threshold A shown in Figure 10 ). In other words, the notification system 80 can use a plurality of measurements to confirm that traffic congestion is present, to avoid false positives, e.g. where one vehicle is pulling over, exiting a highway or turning. By having access to vehicle data 78 for multiple mobile devices 100, the notification system 80 can better distinguish traffic congestion from anomalies and prepare dynamic notifications 84 accordingly.
  • the notification system 80 may determine a set of one or more upstream mobile devices 100 that are headed to or are within a predetermined vicinity of the congested zone 2 at 210.
  • the notification system 80 may then identify mobile device 100A as a candidate for receiving a notification 84.
  • the notification 84 may then be prepared at 212 and sent to the candidate mobile devices 100 at 214.
  • the preparation of the notification 84 at 212 may include substeps (not shown) of determining, based on information in the traffic database 82, forms of communication for the notification 84, and may similarly determine appropriate content for a particular type of alert. For example, mobile device 100A may have selected an available option to receive an auditory alert rather than a visual alert and thus the notification 84 would be prepared accordingly.
  • the routine 204 shown in Figure 10 may be executed continuously, semi-continuously, periodically or according to external events such as the receipt of a certain number of device data 78.
  • the traffic database 82 may be periodically referenced such that as new device data 78 is received, the notification system 80 can dynamically react to changing environments. For example, a first wireless-enabled mobile device 100 may enter a traffic jam, which would not trigger the detection of a congested zone but as additional mobile devices 100 enter that zone, the traffic jam would then trigger. By continually or periodically referencing the incoming device data 78 the traffic jam can be more quickly detected.
  • FIG. 10 also illustrates that the notification system 80 can be adapted to cover multiple zones and can use any appropriate logic to determine which mobile devices 100 (if any) should receive a notification 84.
  • mobile device 100C which is currently in congested zone 2, provides device data 78 that enables an alert to be provided to the user of mobile device 100A but may also receive another notification 84 (not shown) that alerts the user of mobile device 100C of traffic congestion further down stream, which is determined using device data 78 from other mobile devices.
  • the device data 78 is effectively shared amongst all connected mobile devices 100 via the wireless network 200, wireless router 26, and notification system 80, the notification system 80 capable of first organizing and interpreting the device data 78 to provide dynamic and meaningful alerts for each mobile device user.
  • the mobile devices 100 can be used to both give and get information related to traffic congestion.
  • the notification system 80 may also execute different routines 204 for different zones, for example, to account for different circumstances. For example, certain roadways may be known to have significant slow-downs during rush hour and thus different thresholds may apply at different times of the day. In this example, detected speeds of, e.g. 40 kph, in a 100 kph zone may not be considered congestion but normal volume.
  • Figure 19 an example of a variation of the routine 204 is shown. In this variation, the notification system 80, for the particular zone, would first, at 205, determine the time at which the device data 78 was collected.
  • a first set of criteria is used at 206' to select mobile devices that are considered to not be "normal” (e.g. moving slower than expected).
  • a second set of criteria is used, which can be the usual criteria shown in Figure 10 or some other set of criteria. This allows the notification system 80 to lower the threshold during specific times during the day to take into account known or empirically derived information. For example: "Highway 6 is typically slow from 7 am to 9 am”.

  • a map 242 similar to the map shown in Figure 13 , is currently being displayed and, in this example, an intended route 244 is shown, which may have been specified by the user at some other time. It may be noted that in this example, the map program 60 is used for displaying directions but not necessarily providing current location information via the GPS application 54.
  • a menu 263 can be displayed that lists options 264 available within the maps program 60. Of the options 264 shown in Figure 15 , a Traffic Update option 266 can be selected.
  • the maps program 60 can instruct the GPS application 54 to turn on and begin sending device data 78 and receiving notifications 84. This would enable, upon entering a congested zone 2, the user to obtain a map alert 240 such as that shown in Figure 13 , which can identify the congested zone, identify a detour, etc.
  • This also provides additional device data 78 on which the notification system 80 can make its determinations regarding the need for a particular notification in that particular zone. Accordingly, Figure 15 illustrates that communications between the mobile devices 100 and the notification system 80 can be automatic or user-initiated in various embodiments.
  • Figure 16 illustrates an exemplary set of operations for executing the embodiment of Figure 15 .
  • the maps program 60 Upon detecting traffic congestion at 300, or at any other time that the user wishes to begin receiving notifications 84, the maps program 60 in this example provides the ability to initiate the menu 263 and select the Traffic Update option 266 at 302. The map program 60 would then detect selection of the Traffic Update option 266 at 304 and then turn on the GPS receiver 121 at 306 at which time it may acquire device data 78 for the mobile device 100.
  • the notification system 80 may be configured to detect the presence of the mobile device 100 via the wireless router 26, the mobile device 100 may be immediately available to receive a notification 84 at 324 and provide an alert to the user at 326, which is experienced by the user at 328.
  • device data 78 may be prepared at 308 for sending to the notification system 80 at 310.
  • the notification system 80 then receives the device data 78 at 312 and may compare this device data 78 to recent notifications and other information in the traffic database 82 at 314.
  • the traffic database 82 is also updated at 316 with the new device data 78 to contribute to the generation of notifications.
  • the notification system 80 determines at 318 if there is a relevant notification 84 pertaining to the zone in which the mobile device currently is and, if one is not found, the process ends at 320. If a relevant notification 84 can be found, it may then be sent to the mobile device 100 at 322, where it can be received at 324, an alert provided to the user at 326 and the alert experienced at 328.
  • data 78 pertaining to the location and speed of a plurality of mobiles devices can be used to generate dynamic notifications 84 for other mobile devices 100 that may be affected by traffic issues ascertained from the data 78 provided by the plurality of mobile devices 84.
