Modeling Virtual Road Scenarios for Driving Simulators: a Comparison of 3D Models with Different Level of Details
Year: 2020
Type: book-chapter
Abstract: The paper presents a comparative study of a set of four 3D virtual scenarios with four different Levels of Details and the assessment of their performances for driving simulators.The goal of the experiment is to study the efficacy of the representation of each scenario since their realism affects driving behavior and, consequently, the reliability of the driving experience and thus the virtual driving tests themselves.Many elements influence the interaction between the driver, the vehicle, and the environment.The model was elaborated considering six main classes of variables, namely: 1) Road infrastructure; 2) Vehicle characteristics and its performance; 3) Buildings and all other artefacts visible from the vehicle; 4) Events (pedestrians, signalization, animals, lighting etc.); 5) Environmental conditions (rain, fog, night-time and visibility); 6) Traffic (with different levels of service).The experimental investigation was conducted on a sample of young people (19-25 years old) driving along the same road path.The different LODs of the scenarios were presented in random sequence to participants in order to reduce possible bias.A car-simulator equipped with a seat, pedals, gear, steering wheel, and 3 monitors for the panoramic view was used to run the tests.The evaluation of the drivers' reactions is based on psycho and physiological parameters collected during the simulated driving experience.The impact of the different road scenarios on the driving behavior is discussed in the paper.
