Abstract
This study evaluated the impact of an optimal in-vehicle advanced warning information service in a connected vehicle (CV) environment to prevent secondary crashes. Driving simulation experiments were designed and performed to analyze driving behavior. The forward crash situation was reproduced in a simulated highway environment, and the safety effects were assessed based on simulation data from a driving simulator (DS). To explore and analyze the effectiveness of crash notifications from the advanced warning information system (AWIS) for preventing secondary crashes, this study utilized repeated measures of multivariate analysis of variance (MANOVA), repeated measures of ANOVA, paired t-test, and Wilcoxon signed rank test. The results from this paper indicate that a warning information system was effective to prevent secondary crash risks, in general.
