A transport facilitation system is disclosed that can facilitate pick-ups in connection with a transportation arrangement service. The transport facilitation system can initially receive a pick-up request from a user device of a requesting user and select a driver to service the pick-up request. The transport facilitation system can transmit an invitation to service the pick-up request to a driver device of the driver and receive a confirmation to service the pick-up request from the driver device. Thereafter the transport facilitation system can, detect, from the user device, a sensor pattern corresponding to a hailing action performed by the requesting user using the user device. In response to detecting the sensor pattern, the transport facilitation system can initiate a selected display pattern on a graphical user interface (GUI) of the user device to enable the driver to identify the requesting user.
