In this study, the location and equipment items of existing roadside stations in Tokyo and the six prefectures in Kanto were taken into account to evaluate whether they can function as advancement base, rescue activity base, or wide-area material transportation base. For disaster risks, the author considers floods, landslides, liquefaction, and tsunami.
 First, the conditions, locations, and equipment items required for each of the advancement base, rescue activity base, and wide area material transportation base were clarified from the materials of the prefecture's wide area support plan and the Cabinet Office. 
Next, the author conducted a standard survey required for the location and equipment items required for the three types of bases. Location and equipment items are divided into qualitative items and quantitative items, and the criteria for quantitative items were created based on hearing surveys and data collected from existing wide-area disaster prevention bases. 
Next, using the criteria, the author evaluated whether roadside stations in Tokyo and the six prefectures in Kanto could play the roles of three types of bases. The evaluation was made in three items: I )evaluation of the roadside station alone, II)performance comparison evaluation with the existing wide area disaster prevention base, and III) maintenance cost evaluation to supplement the lacking equipment. 
As a result, it was found that there are roadside stations that can be utilized by supplementing the facilities for the "advancement bases" and "wide area material transportation bases". As for the "rescue activity bases", the standard required for the outdoor space area is high, and it is difficult to play a role at the current roadside station.
 Therefore, the challenges for utilizing the roadside station as three types of bases are the complementation of equipment and the expansion of the outdoor space area.
