  • Automated Vehicles - Challenges and Opportunities for Road Operators and Road Authorities - Technical Report

    Vehicle Automation – at SAE levels 3, 4 and 5 – is still in a testing phase in most countries. Many tests at level 3 have been performed successfully on open roads without any changes to the road infrastructure and without any observed impacts on congestion. There are various situations which necessitate that a driver takes control of the vehicle – a fall-back solution that is still allowed at level 3, but not at level 4 or 5. It is likely that some support from the infrastructure will be [...]
