VTI's simulator environment is unique. It currently comprises three large, advanced driving simulators, a smaller training simulator and a rail simulator. The institute uses an in-house developed open source code. VTI can therefore offer experiments tailored to the needs that exist. The facilities are open resources that are can be used by anyone to conduct experiments.
A large part of VTI's research concerns understanding the individual's behaviour in the transport system. In order to continuously improve traffic safety it is important to know how the driver is affected by factors like new technology, driving dynamics, road design, drugs and alcohol, tiredness and driver support systems.
With VTI's driving simulators repeatable experiments can be carried out and realistic driving experiences created. This makes it possible, among other things, to study the effect of the driver's condition and driver support systems on driving performance.
VTI has more than 40 years of experience of using simulators and is a leading authority in conducting simulator experiments and developing simulator technology. In the last few years the use of advanced driving simulators for a more effective product development has gained much attention. VTI is leading the Vinnova financed competence centre VIP, Virtual prototyping and assessment by simulation, which focuses on this topic.
