SimArch 2: Implementation and demonstration of the SimArch architecture

Complexity in modern vehicles consists of an increasingly large multitude of components that operate together. While functional verification of individual components is important, it is also important to test systems of interacting components within...

Evaluation of driving simulator based training for older drivers in Sweden: Deliverable...

Being able to assess your own performance can be vital to maintain safe mobility for older drivers. Overestimation can lead to increased risk of being involved in a crash and underestimation to unjustifiable restrictions in mobility. A pre/post...

Performance and presence with head-movement produced motion parallax in simulated driving

Driving simulator studies can reveal relevant and valid aspects of driving behavior, but underestimation of distance and speed can negatively affect the driver's performance, such as in performance of overtaking. One possible explanation for the...

A Driving Simulation Platform using Distributed Vehicle Simulators and HLA

Modern vehicles are complex systems consisting of an increasing large multitude of components that operate together. While functional verification on individual components is important, it is also important to test components within a driving...

Principle Other Vehicle Warning

The only possibility for a driver to avoid a collision may sometimes be to issue a warning to another driver. Connecting the horn and the headlight to an already existing sensor system could be a cost effective solution. This report covers the...

Tactical driving behaviour with different levels of automation

This paper investigated how different types of automation affect tactical driving behavior, depending on trust in the system. Previous research indicates that drivers wait for automation to act, delegating the monitoring of traffic situations. This...

Learning from experience: Familiarity with ACC and responding to a cut-in situation in...

Response times to risky events have been seen to increase with the use of adaptive cruise control (ACC). It has been unclear whether driver experience with ACC mediates this increase. We compare driving in a cut-in event in a simulator both with and...

Validating on-the-limit properties of a driving simulator

The paper describes a validation model for both subjective and objective comparison of on-the-limit properties of a driving simulator. VTI moving base driving simulator, SIM III, has been used with three different versions of VTI’s vehicle model,...

Driver reactions to horn and headlight warnings in critical situations: A simulator study

This paper presents a driving simulator study on driving behavior in a critical head-on collision scenario. The study aims at providing basic understanding of driver responses to headlight and horn warning coming from another vehicle a time critical...

Effects of motion parallax in driving simulators

Motion parallax due to the driver’s head movement have been implemented and tested in VTI Driving Simulator III. An advanced camera-based system was used to track the head movements of the driver. The output from the tracking system was fed to the...

Trafiksäkerhetspåverkan vid omkörning av 30-metersfordon

The Swedish Road Administration considers permitting longer and heavier trucks on Swedish roads, provided that they do not affect traffic safety. The purpose of the study was to investigate the effect of truck length, particularly accident risk...
