The urban expressway in Japan has severe road alignment due to constraints in construction. It is assumed that the driver's gaze behavior also changes greatly depending on traffic conditions and roadside environment. It's difficult to measure the gaze behavior of the driver during driving on a daily. There is not enough knowledge about analysis of gaze behavior. This research focused on the roadside and traffic conditions on the Hanshin Expressway, then analyzed changes in driver's gaze behavior through actual expressway and driving simulator experiments. As the results, this research obtained results suggesting that gaze behavior influences the viewability of the side walls, traffic conditions, and the presence of dynamic advertisement information in buildings outside the expressway. These obtained results are expected to contribute as one guideline for considering traffic safety measures by sharing them to road managers for reducing accidents in urban expressway operators. This paper also analyzed the relationship between the gaze behavior and driving behavior of the driver in an urban expressway. Experiment on the expressway and experiment using driving simulator clarified how the road structure such as the side wall and the accompanying gaze of the landscape and the surroundings affect the driving behavior.
