A Study on the Guide Signs Layout for Freeway Major Split Interchange
The lack of standards in guide sign layout for freeway major split interchanges in China is imperative to solve considering particular physical form and traffic operation. On the basis of domestic and international standards and specifications, this study designs two types of graphical guide sign in addition to the text-type guide sign in China’s national standard, and forms three placement configurations according to the guide rules. Behavior indicators are obtained through driving simulation experiments, the differences among the indicators of different configurations are studied, the analytic hierarchy of utility evaluation is established on the basis of the three-demarcation analytic hierarchy process, and the utility ranking is acquired through a comprehensive evaluation. Results show that the graphical signs are better than the text-type signs for freeway major split interchanges. This study offers suggestions on the optimal layout for guide signs, which may have certain reference value for improving relevant technical standards in China.
