This paper describes fundamental issues of the traffic management systems and the actual traffic conditions following the Hanshin-Awaji Earthquake. Based on these issues, a new concept of traffic management system against an earthquake disaster is proposed, and the effectiveness of 2-stage area traffic regulation is examined through the case study for accommodation of personal passenger car demand immediately after the earthquake. Additionally an integrated traffic management system against a major earthquake and the related issues are discussed. It is expected that ITS technology will play an important role in the future development of traffic management system during an earthquake disaster.
