On the high-level road network, traffic peaks and traffic volume-related congestion occur throughout Europe especially in urban and metropolitan areas. This is associated with time loss for vehicle occupants and an additional burden on the environment due to increased pollutant emissions. Therefore, motorway operators want to establish an ecologically and efficient transport system and search for alternative measures to use the existing road surface, rather than construct additional lanes as part of their capacity availability strategy. With minor adaptations of the existing infrastructure, an improved public transport accessibility with more attractive public transport travel times and an increase of the traffic performance in the environmental alliance could be achieved. To make more efficient use of the existing road surface and capacity, this study wants to quantify the potential of allowing rapid public buses to use the hard shoulder to bypass congestion. The rail infrastructure and the motorway network have interchanges throughout, but just a few direct transfer and mobility hubs. Therefore, this study aims to foster the linkage of the rail infrastructure and the urban and regional public transport network by investigating efficient interchanges on the motorway, which allow stops without detours and support short travel times.
