Mathematical models for simulation of run-off into the road side area - a review (English)
Mathematical simulations of run-off vehicles into the road side area have the potential to further increase the traffic safety. Large number of scenarios that are costly and time demanding to perform by physical testing can be simulated using computer models. The aim of this review is to describe methods and simulation programs that currently exist and identify challenges within these. This review consists of two parts. The first part is a literature review. The second part is a compilation of the experiences of a consultant in the vehicle simulation area and interviews with persons with vast simulation experience. The conclusion is that currently there is not one optimal program that in detail and with high efficiency can handle all challenges that exist in a description of the scenario when a vehicle enters the road side area. Different programs have various strengths and limitations. One way to address this is to combine different types of programs thereby using the advantages of different programs. Another way is to use one of the crash simulation programs and make simplifications in order to reduce simulation running time. Simulations with these programs can otherwise last for weeks (for one simulation). This study has also resulted in identification of challenges that are present when simulating of run-off vehicles into the road side area. These are in particular related to components that are part of the interaction between the vehicle and the surface (such as tyres, asphalt, gravel, grass etc) and the influence of the driver and active safety systems.
