(2014) 차량 시뮬레이터를 이용한 철도건널목 운전행태에 관한 연구

This study aims to evaluate driver reactions to the introduction of new ITS interventions at railway crossings (RLX) in driving simulator. Systems which complement standard controls at RLXs are not expected to have the same level of integrity (SLI), but could be used by drivers as a primary control; however, these would have negative outcomes in terms of safety at the crossing.

Therefore, studying the effects of such devices must first be performed in a controlled environment, which can be provided by a driving simulator. A little research has been conducted on safety at RLXs [1,2] compared to road intersections since the number of collisions at RLXs is significantly less than road intersections. Even though a few research considered on general safety at RLXs, taking ITS devices into account safety is hardly seen. It implements the interfaces with the highest potential to increase safety at RLXs. A mock-up of the most suitable technology is simulated and tested in an advanced driving simulator. Using an advanced driving simulator has the following advantages: ∙It provides a safer and more economical means of experimenting and testing traffic injury prevention strategies. ∙It facilitates state-of-the-art research that could not otherwise be undertaken on open road settings due to ethical, safety reasons and cost limitations. ∙It provides an environment to test the effect of ITS interventions on driver behaviour (safety) before a costly deployment. Scenarios can be analysed with experimental repeatability, easy configuration ability and excellent data collection capability. This facilitates case control, before and after studies. Finally, it allows quick and inexpensive ways to test many non-existent road safety interventions for railway crossings before trialling the most promising at a real RLX.

However, some of the drawbacks are simulator [3,4], whereby a participant experiences symptoms of motion sickness even after only brief exposure to the driving simulator, due to the lack, or incomplete replication of physical sensations [3]; no possibility to use multiple drivers interacting while driving; and validity of the measures provided by the simulator. This study is a simulated driving task experiment. It aims to assess the effects of various in-vehicle and on-road ITS interventions on driver behaviour at both active and passive railway level crossings. Three different ITS interventions are trialled, as well as a baseline of standard active and passive crossings. This study investigates the following three ITS interventions: ∙Visual warning display of train approaching and/or congestion at active crossing (in-vehicle) ∙Audio warning of train approaching and/or congestion at active crossing (in-vehicle) ∙Valet system: warning lights on the road surface activated as a train approaches (on road-based).

The objective of this study is to evaluate the safety impacts of these different assistive systems on human errors, intentional actions, and objective and subjective risk assessments. This study evaluates the resulting objective and subjective behavioural changes in different traffic situations which are modelled to be representative of the different types of crossings (active and passive). This study used questionnaires for assessing subjective feedback from participants primarily assesses the effects of such interventions on driver decisions and behaviour at railway crossings through: ∙driver awareness at the crossing ∙driver workload when processing the information at the crossing. ∙driver perception of increased safety at the crossing with such systems, as well as driver accept-ance of the system
