This milestone report focuses on the development of human comfort criteria for subway systems. The psychological and physiological aspects of thermal comfort are reviewed. The common indices of comfort are evaluated and the effective temperature and a modification to the relative strain index are selected as the most suitable for use in developing criteria in a subway rapid transit system. The concept of relative comfort is introduced as a means of computing the temperature required to achieve the desired comfort level. Criteria for rapid pressure changes, high air velocities and air quality are also given.
