Automation-ready modelling – how does it work?

The following steps were undertaken to achieve this milestone:

• Co-simulations were run thanks to a connection between the control logic of VEDECOM, the software PreScan from TASS International and the microscopic simulation software Vissim.
• Field data were collected on the test track in Helmond, where TASS International organised a 3-day data collection session in a real-traffic environment.
• The data and the car-following behaviour of the automated vehicles were analysed. Based on these results, new features were released in Vissim 11 and the recommended values published. Furthermore, the results were used to develop scripts for macroscopic modelling.

The simulation of automated vehicles with the microscopic software PTV Vissim has been improved: thanks to the drivermodel dll interface or the API driving simulator interface, the users can now either use their own algorithms or the new features available in Vissim 11. The influence of automated vehicles can also be studied at the macroscopic level (i.e. with Visum) thanks to the scripts developed by the University of Stuttgart.

Now that the modelling software is AV-ready, the four roads authorities involved in CoEXist: Gothenburg, Helmond, Milton Keynes and Stuttgart will model their use cases using the microscopic simulation software, PTV Vissim and the macroscopic modelling software, PTV Visum.
