Distribution of location and movement information of meeting participants

A first mobile computing device comprising a non-transitory computer readable medium storing instructions that, when executed by a processing device, cause the processing device to:

• ascertain a location of a first mobile computing device of a first carpool participant at a predetermined time with respect to a scheduled carpool time;
• calculate a speed of the first mobile computing device based on a measured change in location of the first mobile computing device over a known time period;
• receive a location and a calculated speed of a second mobile computing device of a second carpool participant ascertained by the second mobile computing device at the predetermined time;
• classify the calculated speed of each respective mobile computing device relative to a stationary, a walking, or a driving speed;
• calculate an expected arrival time of each respective carpool participant at their scheduled carpool meeting location based on their classified speed and a distance between the ascertained location of their mobile computing device and their scheduled carpool meeting location;
• compare the expected arrival time of each respective carpool participant to their scheduled arrival time;
• and
• depict on a map displayed on the first mobile computing device the location of each mobile computing device and an indication as to whether the expected arrival time of at least one carpool participant and their mobile computing device is within a predetermined period of their scheduled arrival time.

A first mobile computing device comprising:

• a receiver receiving location data from an external source to the first mobile computing device;
• a processing device configured to:
• ascertain a location of the first mobile computing device using the location data received at the receiver at a first predetermined time before a scheduled event;
• calculate a speed of the first mobile computing device based on a measured change in location of the first mobile computing device over a known time period;
• receive a location and a calculated speed of a second mobile computing device ascertained by the second mobile computing device at the predetermined time;
• classify the calculated speed of each respective mobile computing device relative to a stationary, a walking, or a driving speed;
• calculate an expected arrival time of each user of the respective mobile computing devices at their scheduled meeting location based on the classified speed of their mobile computing device and a distance between the ascertained location of their mobile computing device and their scheduled meeting location;
• compare the expected arrival time of each user to their scheduled arrival time;
• and
• depict on a map displayed on the first mobile computing device the location of each mobile computing device and an indication as to whether the expected arrival time of at least one user is within a predetermined period of their scheduled arrival time.
