SYSTEM AND METHOD FOR FASTER DETECTION OF TRAFFIC JAMS
First Claim
1. A mobile device, comprising:
- an interface to a wireless network;
a memory storing data defining segments of roads; and
a traffic probe module coupled with the memory and with the interface to the wireless network and fortracking traversal of the mobile device on a segment of road,responsive to completing traversal of the segment of road, sending a report of the average speed of the mobile device on the segment of road, andsending a report with data for an average speed and an indication of a portion, less than entirety, of the segment of road that has been traversed, responsive to determining existence of an unexpected condition on the segment of road.

Abstract
Devices located with moving objects (e.g., people or cars) can function as probes of traffic conditions. One way that such probes can operate is by making sporadic reports (e.g., for example, after a given road segment is traversed, a report can be made). However, in such a reporting scheme, a traffic incident that prevents or delays completion of that road segment would go unreported until the probe finished the segment. Thus, these aspects provide methods and systems to detect unexpected conditions that prevent/delay completion of such road segments, and responsively generate an out-of-cycle report that can be used in alerting others of such condition. Progress on that segment can continue to be monitored, with periodic updates, when the segment ultimately is finished, the probe can send a final report for that segment. The report can contain data indicative of an average speed on the road segment (or the portion of it completed, when detecting an unexpected condition).

11. A method of sending traffic information from a mobile device, comprising:
-
tracking traversal by the mobile device of a segment of a road that is defined by definition data store on the mobile device; responsive to completing the road segment, reporting data from which an average speed of the mobile device on the road segment can be determined; and responsive to determining that traversal progress of the mobile device on the road segment deviates from an expectation by more than a threshold, reporting an average speed for a completed portion of the road segment, prior to completing the road segment. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for providing traffic information to mobile devices, comprising:
-
receiving, from a first mobile device, a message identifying a pre-defined road segment, a portion of the road segment traversed by the first mobile device, which is less than an entirety of the road segment, and data from which an average speed of traversal for that portion of the road segment can be determined; determining existence of a traffic event for the road segment, based on the message; identifying a second mobile device traveling towards the road segment; and sending an alert to the second mobile device concerning the traffic event. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
