In last years, driving simulators have had an increasing use in researching highway
geometric design. However, research simulators have high costs. A possible solution to
avoid these costs is using videogame simulators. Videogame racing simulators have
achieved high quality with a moderate cost. Some of these games include very detailed
models that describe very accurately the performance of the simulated vehicles. In addition,
they provide very realistic images of the car, the highway and their surroundings.
With the aim of using them as research tools, several of the most popular games have been
analysed. Two of them have been selected: rFactor2 and Assetto Corsa. Also, a 3D model
of a section of an actual highway has been made and adapted to be used by the
aforementioned games. Some tests have been conducted using a custom computer system,
and the modelled highway section, with both game simulators. From these tests results, both
sim racing software can be used to build a low cost driving simulator useful for road
geometric design research.
