Digibus®: Public Demo Operation in Koppl
For the first time, the automated Digibus® will operate on a scheduled timetable in a public demo operation during August, September, and October 2020. This demo operation in the Salzburg municipality of Koppl will test both the integration of a self-driving shuttle into a regional mobility system and new interaction concepts under real-world conditions. All rides on the Digibus® are free of charge.
Since 2017, occasional test drives with self-driving shuttles from various manufacturers have been conducted in the Salzburg municipality of Koppl. The focus of this Salzburg scenario is on bridging the first and last mile, thereby enhancing the existing public transport system with automated supplementary services. Now, for the first time, the Digibus® will be tested on a scheduled timetable as part of regular operations and integrated into the public mobility system. No ticket is required for rides on the Digibus®.
"Testing under real-world conditions – on a regular road with various traffic situations inside and outside the town, including inclines, left-turn scenarios, and interactions with other road users – revealed challenging details in the areas of driving safety and autonomy. The solutions developed for these challenges will now be tested during the 2020 demo operation," says project leader Karl Rehrl, head of research lines at Salzburg Research.
New Interaction Concepts on the Bus
Particularly with the prospect that no operator may be required on board in the future, significant work has been done on the vehicle's communication with other road users. "In a fully automated context without an on-site contact person, the bus must communicate very clearly. Over the past few months, solutions for incident management, capacity management, and interaction concepts with passengers and other road users have been developed," Rehrl adds.
During the demo operation, further developed solutions previously tested in the lab will be used, including passenger information and capacity management systems from the Center for Human-Computer Interaction at the University of Salzburg. These systems are implemented on outdoor-compatible touchscreen communication terminals from Commend. Displays on the bus and at bus stops provide trip and connection-related information to better integrate the Digibus® into public transport and enhance the passenger experience.
In recent months, the project consortium has also worked intensively on areas such as customized layouts, user interface design, user experience, and audio signal processing for better speech intelligibility on the road. A highlight is the intelligent interaction with the chatbot voice assistant developed by Commend.
Framework for the Demo Operation
- Timetable: The demo operation runs from August 10 to August 28 and from September 21 to October 16, 2020. During this time, the Digibus® will operate on weekdays in five trips between 9:00 AM and 1:30 PM as a supplement to Line 152. This will temporarily increase the current hourly service of Line 152 to a half-hourly service.
- Route: The Digibus® operates between Koppl town center and Koppl Sperrbrücke (connection to Line 150 Salzburg – Bad Ischl).
- Operator on Board: As before, a trained operator is required on public roads to monitor operations and intervene if necessary. During the demo operation, a staff member from Postbus AG will always be on board.
- COVID-19 Measures: Wearing a face mask is mandatory. In addition to the operator, either three individuals from different households or four individuals from the same household may board. The shuttle will be regularly disinfected by the operator between trips.
3rd Generation of the Digibus®
The 2020 demo operation will use the third and latest generation of the EasyMile EZ10 shuttle. This version features improved sensor technology: the LIDAR sensors now have 32 layers instead of 16 and are positioned differently. Additionally, the shuttle is now only capable of monodirectional driving, which complies with the regulations of some countries for automated shuttles to be approved for road traffic.
The new shuttle was delivered to Koppl in May 2020. Since then, preparations for the demo operation, operator training, and technical tests have been underway.
As before, the Digibus® operates with a test license plate (registered to Salzburg Research) and a special permit from the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation, and Technology (BMK), as regular road approval for automated vehicles is not yet available in Austria.
Flagship Project "Digibus® Austria"
In the Austrian flagship project "Digibus® Austria", a high-profile consortium led by Salzburg Research is researching and testing the reliable and safe operation of automated minibuses in public transport. The autonomy and driving safety of autonomous vehicles are to be further improved.
The flagship project "Digibus® Austria" runs until March 2021 and is funded under the research program "Mobility of the Future" by the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation, and Technology (BMK). Leading companies and research institutes along the entire value chain of public transport, from vehicle providers to mobility service providers, contribute to the results:
- Research Partners: Salzburg Research (project lead), Virtual Vehicle Research GmbH, AIT Austrian Institute of Technology GmbH, University of Salzburg – Center for Human-Computer Interaction, University of Natural Resources and Life Sciences (BOKU) – Institute for Transport Studies, FACTUM, apptec ventures GmbH.
- Corporate Partners: Kapsch TrafficCom AG, PRISMA solutions EDV-Dienstleistungen GmbH, Commend International GmbH, Fluidtime Data Services GmbH, HERRY Consult GmbH, ÖBB-Holding AG, EasyMile SAS.
- Associated Partners: Land Salzburg, Land Lower Austria, ÖAMTC Fahrtechnik GmbH, A1 Telekom Austria AG.
