VTI's simulator environment is unique. It currently comprises three large, advanced driving simulators, two train simulators, a bicycle simulator, a pedestrian simulator and some small scale simulators for dedicated applications. 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 human behavior 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, vehicle characteristics, traffic environment, road design, drugs and alcohol and tiredness.
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 vehicle 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. During 2008-2017 VTI was the coordinator of the Vinnova funded competence centre ViP, Virtual prototyping and assessment by simulation. It had a focus on virtual methods within the automotive industry.
In the last few years the use of simulators in training of professional drivers has gained much attention among train operators and emergency operators. VTI is coordinating a forum for train operators and schools, TUFFA, where it is agreed on what type of development should be prioritized.
