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).
