Optimal design of the long tunnels with large cross sections essential for the effective development of the limited land in Korea becomes more and more difficult owing to the constantly changing social, economic, environmental and technological factors. Deficiency of the domestic research works till now on the elementary topics on tunnel ventilation retards progress on developing the key technologies urgently required for designing and managing the long and large tunnels. This paper aims at identifying the subjects on which research must be carried out for the construction and management of vehicle tunnels in Korea by means of scrutinizing the contents of the publications since 1991 at the International Symposium on Aerodynamic and Ventilation of Vehicle Tunnels, the only international conference on the tunnel ventilation.
