This study proposes a tentative procedure for managing the intelligent transportation systems (ITS) information presented to drivers so as to minimize interference during driving and promote safety. The information can be classified into three categories according to its purpose: warnings, route-related information, and multimedia services. The presentation of warnings should take precedence, with route-related items requiring the driver's immediate attention being given secondary priority. Route information and multimedia services not requiring immediate attention can be presented if warnings or essential route information are not being presented. A driving simulator experiment demonstrated that the information management procedure, which was constructed on the basis of experimental results, could improve the acquisition of ITS information; this procedure is particularly important for ensuring the effectiveness of advanced warnings.
