On 27 – 28 June 2023, the i4Driving team met in the city of Naples for their second in-person meeting. The two-day event started with a crash course organised by TU Delft on OTS, to let participants to use/test the basics of the OTS with scenario creation and simulation experiments and scripting. Thereafter, the team launched into the second part of the meeting, which was a workshop on Milestone 3 (use-cases, scenarios and experiments setup) to discuss what scenarios need to be tested (DSEs, test tracks) and modelled in the i4Driving project. The first day had presentations from UNINA on how to capture the relevant behavioural mechanisms for safety assessments and then from VTI and the Technical University of Munich on the approach followed thus far for the development of the research questions, hypotheses and scenarios. An interactive discussion was held thereafter on the various hypotheses that had been selected, to decide which ones should be prioritised within the project.
The second day began with sessions on modelling as part of WP2. These focused on the importance of sensitivity analysis, showed how the first results of sensitivity analysis could be applied to ‘Task Demand’ and car-following modelling and provided updates on the technical progress regarding the software to be used within the project. Thereafter, the team split into two groups; the first group discussed the modelling approach and framework in more detail, while the other group discussed the hypotheses and scenarios to be tested, following from the discussion held on the first day. We ended off with a presentation from SwissRe on approach to risk modelling and a presentation by the University of Warwick on the relevant scenarios and the simulators they have, as well as the Safety PoolTM Scenario Database.
Fruitful discussions were held and the team decided on several hypotheses which are essential for testing within the project and also set follow up meetings to reach consensus on the remaining hypotheses, scenarios and use cases to be tested.
