VIIS (Vehicle Infrastructure Interaction Simulation), an actual research project which was started
in January 2008 has the aim to build up on the MARVin (Model for Assessing Risks of Road
Infrastructure) outcomes. The idea is to develop a combined simulation system, including all
kinds of RoadSTAR data (Road Surface Tester of arsenal research; road condition and trace
geometry) to verify crash causal combinations.
The MARVin software tool has been upgraded with traffic density data to get some more
comparable and significant results. The crash causations regarding to poor surface characteristics
or in-harmonic road geometry can be identified with a higher probability.
The main work is to integrate all relevant RoadSTAR parameters in a simulation software tool.
In a beginning procedure a potential integration in the software PC Crash shows some positive
results. The challenge will be to bring the skid resistance values in a high density on the virtual
route - the data format DXF allows colour layers for each skid resistance value.
Road sections in a virtual reality can be designed with real measured data. Crash reconstructions
and crash causal combinations (MARVin) are feasible. All kinds of vehicle dynamic data, which
can be also logged in the Bus system, can be simulated and recalculated. The vehicle
infrastructure interaction (road/tyre, suspension/tyre) in a crash situation leads to possible
compensation chances. New in-vehicle sensors, active safety systems, real time accident risk
assessment, interactive road condition maps, etc.
The key point for the future of traffic safety issues are to verify MARVin results with vehicleinfrastructure
simulations and to derive preventative measures either on the construction side or
in the in-vehicle safety applications. Visions are to combine theoretical accidentology with
practical preventative solutions. Policy, vehicle manufacturer, road operators and map providers
can have a benefit resulting from this research.
