Abstract: Systems, methods and computer program products for using location data from mobile devices to estimate the length of queues for a resource are described herein. An embodiment includes identifying a queue location for a resource, receiving a plurality of periodic updates from a plurality of mobile devices in the queue location, each periodic update including an identification and a position of the mobile device and a time of measurement, and storing the identification, location and time of measurement for each device in a queue data structure. The embodiment further includes determining when a device exits the queue location and moving the stored information for that device from the queue data structure to an exit data structure. Methods are provided for using the information in the data structures to estimate the length of the queue, waiting time and the speed of the line.
