A system can receive a request for a service from the computing device of a given user of the network service. Based on the request, the system can determine a vehicle stopping location for a driver of a vehicle that is to service the request, and transmit map data to the computing device of the driver to present map content indicating (i) the vehicle stopping location for a vehicular portion of the service, and (ii) a path for the driver from the vehicle stopping location to a target location, the path to be followed by the driver upon parking the vehicle at the vehicle stopping location. The system can further transmit a set of delivery instructions to the computing device of the driver to specify one or more actions for delivering an item to the given user at a location specified by the given user.
