The location information may be collected based on an ascertained location of a mobile computing device carried by a participant. The location of each participant's mobile computing device may be obtained through the use of location based services. Each participant's device may push geographic location, speed, and/or movement type information (such as whether the participant is walking or driving) to a central system. The pushed data may then be pulled from the central system by the devices of other interested participants. Methods, computer readable media, and devices are provided. ## Claims ### Claim 1 A method for dynamically distributing location information between carpool participants comprising: ascertaining a location of different mobile computing devices of different carpool participants at a predetermined time with respect to a scheduled carpool time;

classifying the speed as walking when the calculated speed is between 1 km/hr and 10 km/hr; and classifying the speed as driving when the calculated speed is above 10 km/hr. ### Claim 5 (depends on 4) The method of claim 4, further comprising calculating a time required to travel a shortest route at the classified speed from an ascertained location to a scheduled carpool meeting location to calculate the expected arrival time of each respective carpool participant. ### Claim 6 (depends on 1) The method of claim 1, further comprising transmitting the scheduled arrival time update to a mobile computing device of a carpool participant requesting to receiving the scheduled arrival time update. ### Claim 7 (depends on 1) The method of claim 1, further comprising automatically transmitting the scheduled arrival time update to a mobile computing device of each carpool participant when the scheduled arrival time update is complete. ### Claim 8 (depends on 1) The method of claim 1, further comprising: comparing a plurality of ascertained locations of a plurality of mobile computing devices of the carpool participants to each other; recalculating a carpool route, a scheduled carpool meeting location of at least one carpool participant, and a scheduled arrival time of at least one participant based on the comparing to minimize a duration of the carpool; transmitting the recalculated carpool route, the recalculated scheduled carpool meeting location, and the recalculated scheduled arrival time to the mobile computing devices of those participants affected by the recalculating. ### Claim 9 (depends on 8) The method of claim 8, further comprising transmitting the recalculated carpool route, the recalculated scheduled carpool meeting location, and the recalculated scheduled arrival time as part of an update shown on a map of a mapping application on the respective mobile computing devices of those participants affected by the recalculating. ### Claim 10 (depends on 1) The method of claim 1, further comprising: comparing a plurality of ascertained locations of a plurality of mobile computing devices of the carpool participants to each other; recalculating a carpool route, a scheduled carpool meeting location of at least one carpool participant, and a scheduled arrival time of at least one participant based on the comparing to minimize a total distance traveled by each of the carpool participants from their ascertained locations to their recalculated scheduled carpool meeting location;
