Embodiments provide techniques, including systems and methods, for improving the accuracy of location information for requestor and provider devices in an dynamic transportation matching system using local communications between computing devices. For example, embodiments allow a provider computing device to identify, pair, and/or communicate with a requestor computing device upon arrival near a request location for a ride matching request. The provider computing device may use signal strength measurements associated with signals received from the requestor computing device to identify a proximity to the requestor computing device and/or to triangulate an accurate location of the requestor computing device. Additionally, the provider computing device may use a combination of the location reported by the ride matching system and the signal strength of the paired connection to identify the location of the requestor computing device.
