Autonomous shuttles will make history in Switzerland today when they begin carrying passengers in the historical district of Sion, the largest city in the Canton of Valais. Two vehicles will wend their way along the edge of town and through the pedestrian area, and stops will include the Place de la Planta and the Place du Midi. This pilot project, which is part of the Mobility Lab Sion Valais initiative, is an opportunity for EPFL researchers to test and improve their traffic and fleet-management algorithms.
