A computer-implemented method for determining a change in a mode of transportation, the method comprising: determining with a mobile computing device (304, 504, 804) a change in a mode of transportation of the mobile computing device (304, 504, 804) by determining that a speed of the mobile computing device (304, 504, 804) has changed; determining a particular geographical location at which the change in mode of transportation occurred; and storing the particular geographical location at which the change in mode of transportation occurred; characterized by: determining the change in the mode of transportation of the mobile computing device (304, 504, 804) is performed, at least in part, based on the particular geographical location being in one of one or more geographical locations at which a change in a mode of transportation of other mobile computing devices has previously been determined; the method further comprising: displaying a graphical indication of the particular geographical location at which the change in mode of transportation occurred that is different than graphical indications for one or more other geographical locations of the mobile computing device (304, 504, 804) at one or more other times that were not determined to correspond to a change in mode of transportation. determining with a mobile computing device (304, 504, 804) a change in a mode of transportation of the mobile computing device (304, 504, 804) by determining that a speed of the mobile computing device (304, 504, 804) has changed; determining a particular geographical location at which the change in mode of transportation occurred; and storing the particular geographical location at which the change in mode of transportation occurred; characterized by: determining the change in the mode of transportation of the mobile computing device (304, 504, 804) is performed, at least in part, based on the particular geographical location being in one of one or more geographical locations at which a change in a mode of transportation of other mobile computing devices has previously been determined; the method further comprising: displaying a graphical indication of the particular geographical location at which the change in mode of transportation occurred that is different than graphical indications for one or more other geographical locations of the mobile computing device (304, 504, 804) at one or more other times that were not determined to correspond to a change in mode of transportation. determining the change in the mode of transportation of the mobile computing device (304, 504, 804) is performed, at least in part, based on the particular geographical location being in one of one or more geographical locations at which a change in a mode of transportation of other mobile computing devices has previously been determined; the method further comprising: displaying a graphical indication of the particular geographical location at which the change in mode of transportation occurred that is different than graphical indications for one or more other geographical locations of the mobile computing device (304, 504, 804) at one or more other times that were not determined to correspond to a change in mode of transportation.
