USER NEEDS FOR ROAD INFORMATIONDURING DISASTERS: LESSONS LEARNED FROMTHE TOKACHI-OKI EARTHQUAKE

摘要

We conducted questionnaire surveys on road users at "Michi-no-eki" roadside rest areas,rnmanagers of such areas, and visitors to our website, shortly after the Tokachi-oki Earthquakernof September 2003. The surveys aimed to clarify the needs for road information duringrndisasters, and challenges in providing such information. It was found that there is a need forrnimmediate road information (on road closure, traffic regulation, and the like), for broader andrnmore rapid provision of information by the media, and for improvement of informationrnprovision by Michi-no-ekis.
