Switzerland has joined a growing number of places around the world exploring the potential of electric autonomous buses, with a pair of driverless shuttles now ferrying passengers around the city of Sion as part of a two-year trial. Other autonomous buses being tested out across the globe include the EZ10 in California and Singapore, the Navia also in Singapore, and the IBM-powered Olli in Washington DC that can even talk to its passengers en route. Much like these projects, Switzerland's buses will take to public roads with local regulators eying a wider deployment of low-carbon, autonomous mass transport. The vehicles will be operated by Switzerland's leading public bus operator, PostBus, and will navigate Sion's city streets using software developed by startup BestMile, which spin out of the Swiss Federal Institute of Technology in Lausanne (EPFL).
