Initial study indicates public acceptance for self-driving buses

PostBus is presenting its first acceptance study on automated driving in Switzerland. It shows that those who have already travelled in a self-driving Postbus have more confidence in the technology, and many even wish there were more of these types of bus on the road. Alongside the SmartShuttles project on public roads, PostBus is to gather further experience on a test area in Berne. Swiss Post is promoting the mobility solutions of tomorrow with targeted innovation projects.

SmartShuttle in Sion
SmartShuttle in Sion

PostBus is one of the world’s first providers to operate automated buses for passenger transport on public roads. Two SmartShuttles have transported more than 25,000 people around the center of Sion since 23 June 2016. Another 25,000 passengers have travelled with the two demonstration SmartShuttles that PostBus has used up to now at around 20 events in Switzerland and elsewhere in Europe.

An important goal of the SmartShuttle project is to find out whether the public is positive about self-driving buses. Daily operations in Sion and external events have shown that most passengers are curious before their journey, very alert during it and relaxed afterwards. Some of them have even started travelling regularly on the vehicles. External experts commissioned by PostBus then appraised these observations, gathered from several thousand journeys. On Tuesday 12 September 2017, PostBus presented the results of two qualitative and quantitative studies on acceptance and impact; one conducted by the market research company GIM Suisse AG and the other by the University of Applied Sciences of Western Switzerland (HES-SO Valais-Wallis). These are the first studies on the topic of acceptance on self-driving buses to be conducted in Switzerland.

Acceptance rates higher in Switzerland than the USA and China

In the survey conducted between April and June 2017, around 400 people were asked what they think about automated vehicles in general and self-driving buses in particular. Face-to-face interviews were conducted locally in Sion with shuttle passengers, cyclists and car drivers, pedestrians, shop owners and residents. In addition, telephone surveys were conducted with people who have never experienced automated driving themselves. These surveys were held in the cities of Lucerne, Schaffhausen and St. Gallen.

Here the most important average figures: 51 percent of those surveyed have no or very minor concerns about the use of self-driving buses. In Sion, where automated buses are part of everyday life on public roads, this group constituted 62 percent. 49 percent (38 percent in Sion) of people have moderate to major concerns about boarding a self-driving bus. The GIM study also cited findings from an international study (Schoettle, B. & Sivak M. (2014) - Public opinion about self-driving vehicles in China, India, Japan, the US, the UK and Australia). In China, 87 percent of people have major concerns about self-driving public transport; in the USA, 78 percent; India, 77 percent; and Japan, 75 percent.

Pilot projects increase acceptance

The results generally underscore the observations made: people who have already travelled with SmartShuttles are significantly more positive about self-driving buses. They even express concrete ideas for improvement and suggest new ways of deploying the technology to expand what is on offer. For example, higher speeds, longer routes or the use as shuttles on hospital or company premises. People who have never travelled on a self-driving bus are more reserved. In general, the Swiss population tends to be positive towards self-driving buses by international standards.

The survey conducted by the University of Applied Sciences of Western Switzerland (HES-SO Valais- Wallis) in parallel to the GIM study underline the latter’s results. Those who have already travelled in an automated bus have hardly any or no concerns when it comes to safety. HES-SO Valais-Wallis conducted an observational study in Sion on how other road users responded to a SmartShuttle in their direct vicinity. The results show that self-driving buses merge seamlessly into the city’s transport network and provoke hardly any negative reactions. One of the greatest challenges remaining is the communication between the shuttles and other road users to ensure traffic flows are optimized and yet organized in a balanced way.

PostBus now also holding tests at a closed area in Berne

The project managers will soon decide whether the test phase in Sion will come to an end on 31 October 2017 or be extended and expanded to include further locations. Alongside the operations conducted on public roads, PostBus and Swiss Post have also brought a closed test area into service in Berne’s Stöckacker district. The area is being used to operate new functions as part of automated driving within public transport. The on-demand function, for instance, had its Swiss première today at the area with guests including Erwin Wieland, Deputy Director of the Swiss Federal Roads Office, media representatives and partners. PostBus CEO Daniel Landolf and Swiss Post CEO Susanne Ruoff demonstrated that they could summon an unmanned PostBus with just a click on a smartphone. The function should be available on public roads in the medium term. However, unlike in closed areas, an attendant will be on board each bus operating in public spaces in accordance with the regulations.

Swiss Post and the future of personal mobility

The need for mobility among the population continues to increase and combined mobility is growing in importance. Together with its partners Swiss Post aims to smartly and digitally combine and interlink the various forms of mobility across all modes of transport in Switzerland. To build upon its 100-year history, PostBus will offer more than simple bus services – i.e. increasingly integrated and flexible mobility solutions – from door to door. Swiss Post will work closely with various partners to achieve this goal. Initial pilot projects such as the “NordWestMobil” mobility platform and the SmartShuttles trial indicate the direction things will be heading. The expansion in bike-sharing schemes in major cities such as Zurich, Berne, Lausanne, Lugano and others, is also highly significant for PostBus as a fully integrated mobility provider. Swiss Post launched the Sion/Valais mobility lab in 2014 in conjunction with the Canton of Valais, the city of Sion, ETH Lausanne and HES-SO Valais-Wallis to help combine innovative developments and collaboration with partners and systematically drive initiatives forwards.
