Abstract: A last-mile transportation system has previously been developed using semi-autonomous driving technologies. For traffic management of this system, travel requests are gathered at a central server and, on this basis, the operation schedule is periodically updated and distributed to each vehicle via intermediate servers. However, the entire traffic system may stop if the central server malfunctions owing to an unforeseen event. To address this problem, we propose a fault-tolerant mechanism for the traffic management system of a last-mile transportation service. We use a modified primary-backup (or so-called passive) replication technique. More precisely, one of the intermediate servers is chosen as the central server and the other intermediate servers periodically receive state-update messages from the central server, allowing them to update their state to match that of the central server. If the central server fails, one of the node servers is selected to take over as the new central server. The present paper also demonstrates the availability through failure patterns in experiments with a prototype implementation. (More)
