The first interactive INFRAMIX workshop will take place on 14 May as part of the Automobile Barcelona Fair. Hatun Atasayar, from the Automated Mobility Team at AustriaTech, explains in an interview more about the contents of the workshop and gives a short outlook.


Hatun, can you briefly summarize again what INFRAMIX is and what is the aim of the project?
INFRAMIX is an EU-funded research project dealing with the requirements of both digital and physical transport infrastructure. The focus lies on preparing motorways and expressways for mixed traffic of automated and non-automated vehicles. The project will run for 36 months, i.e. until May 2020. One of the major results so far are the Infrastructure Support Levels for Automated Driving (ISAD), which were jointly developed and will also be discussed at the upcoming workshop in Barcelona.

Can you briefly explain the ISAD Levels?
The ISAD Levels describe the degree of digitization of the infrastructure. For this purpose, a scheme is proposed analogous to the SAE Levels to show the extent to which vehicles can be supported by the Digital Transport Infrastructure (DTI). For example, vehicles will be communicated by the infrastructure "Use track 2, because on track 1 there is a construction site in 500 meters". The ISAD levels go from A to E: E means that there is no digital infrastructure at all and A is the highest level.



What will be covered at the upcoming INFRAMIX workshop?
An important topic are the ISAD levels mentioned above. In the course of a panel discussion with experts, these levels will be discussed and thus further elaborated and improved. The experts belong not only to the INFRAMIX project team, but also from other projects and platforms such as MAVEN, ARCADE or the ERTRAC Working Group on Automated & Connected Driving. It is particularly important for us to obtain the opinions of external experts who critically question our approaches, look at them from different perspectives and bring in new findings from their projects. Of course, all participants can also participate with questions and contributions. The discussions should also connect the ISAD levels with SAE and ODD levels. It is necessary to find a common way of thinking so that the different levels are in accord with each other. A further focus of the event is on user experience, i.e. the perception of road-users. Specifically, it will deal with the possibilities of visual marking for the "dedicated lane" on the physical infrastructure. This traffic sign will be necessary to inform drivers of non-automated vehicles that a certain lane is a dedicated lane. During the event, participants will have the opportunity to get to know the INFRAMIX scenarios in the form of videos and visualizations.


What kind of output do you expect?
We want to further develop the ISAD levels through the discussions at the workshop. These were presented at the ITS World Congress a year ago, since then we have been working on them and with the new inputs from the workshop we want to improve the ISAD levels even further.

Thank you very much for the interview.
