A computing system can receive input data specifying a destination location for a requesting user and determine a guaranteed upfront cost for transporting the requesting user to the specified destination location. The system can cause the computing device of the requesting user to display a ride service selection interface comprising a graphic feature indicating the guaranteed upfront cost for the specified transport option. Based on a user selection of the graphic feature, the computing system can select a driver from the one or more available drivers based, at least in part, on a proximity of the selected driver to the current location of the requesting user, and determine a rendezvous point at which the requesting user can rendezvous with the selected driver.
