Systems and methods are disclosed that use available information about the state of mobile devices in a heuristic-based approach to improve motion state detection. In one or more embodiments, information about WiFi connectivity of mobile devices may be used to improve detection of a transport condition. WiFi connectivity information may be used with sensor signals, such as accelerometer signals, in a motion classifier to reduce false positives in transit. In one or more embodiments, the information that the mobile device is connected to a WiFi access point (AP) may determine the probability of misclassifying the mobile device as in transit if the mobile device is actually in the hands of a relatively stationary user. It may be used as heuristics to reduce. Information about the state of charge of the battery or the wireless connectivity of the mobile device may also be used to improve detection of the state of transport.
