Devices, methods, and systems for navigating an indoor area such as an indoor transit system using a mobile device are described herein. The method may include navigating a network of indoor pathways and a plurality of access points for entering/exiting the indoor pathways. The indoor pathways may be mapped and may include a plurality of beacons distributed at designated locations throughout the indoor pathways. The beacons may be detected using a mobile computing device and an indoor location of the mobile computing device may be determined and depicted on the map of the indoor pathways. The location of the mobile computing device may be used to determine a route from the location of the mobile computing device to a destination in or adjacent the mapped indoor pathways.
