ABSTRACT

The main objective of this study is to enhance highway safety among vulnerable users such as children and elderly people through the investigation of crash characteristics and travel behaviors affected by a rapid demographic change. Both the conventional linear regression model and a beta regression model were estimated with 11 independent variables. No variable was found significant by the conventional regression model at 95% significance level whereas seven variables turned out to be significant in the beta regression model, indicating that it is very important to consider the characteristics of a dependent variable in model estimation process. It is found that two independent variables were positively related with the ratio of crash occurrence while the other five variables were negatively associated.
