Title:

Gap-Acceptance Behavior at Priority Intersection: Field Observations Versus Experiments with Driving Simulator

Abstract:

In recent years, driving simulators have become an interesting tool to improve the analysis of driving behavior as a suitable alternative to field studies. The main reason for this is that field studies are very expensive and characterized by complexity in data collection and by difficulty in making measurements under controlled traffic conditions. On the other hand, driving simulators have several positive features such as efficiency, low expenses, time saving, safety, experimental control and data collection ease. The main problem in using a driving simulator is that the simulated situations are quite often far from the real ones. In particular, the lack of risk on a simulator is the main difference with real conditions. Therefore, a driving simulator must be validated in order to use it for driver behavior analysis. The main goal of this work is to validate a driving simulator with reference to gap-acceptance behavior at road intersections. In order to test the driving simulator ability to represent adequately a real situation, a comparison with real behavior has been carried out. The participants were asked to perform a right turn maneuver at a three-leg intersection. The positions and speeds of the subject vehicle and of the other simulated vehicles were recorded with a resolution of 0.1 seconds. The results obtained appear interesting and confirm that a driving simulator can be used for representing drivers behavior at intersections; moreover, the findings of the research suggest the usefulness of driving simulators for road traffic accident analysis and prediction.
