Specification of origin of the destination mistake on expressways

Abstract

In order to take measures effective against a reverse run on an expressway that poses a social problem, we need to grasp a process of driving leading to the reverse run. In this research, we first presented a hypothesis about this process and then verified it. As a result, we found the possibility that a trigger of the reverse run would be a destination mistake such as passing through a target interchange. Next, on the basis of this result, we examined the factors of occurrence of destination mistakes. Specifically, in consideration of the use situation of car navigation and guide signs, we identified the situation in which the destination mistake easily occurred. In addition, we investigated the tendency of attribute and information collection of individuals with reference to target people for analysis belonging to each situation. As a result, it was understood that the factors of occurrence of destination mistakes were that there was a tendency in which the target people did not refer to the guide signs while thinking highly of the guide of car navigation, and that they were not able to fully utilize the guide sign information on urban expressways.
