The purpose of this study is to reduce of computation time, and to propose of the efficient data acquisition technique because of improvement in the practicality of a city fire simulation. As a result,(1)the city fire simulation program was Improved of efficient radiant heat transfer calculation methods and the multi-core parallel processing,(2)the city fire model in consideration of imperfection of city information was developed,(3)an influence which the position of openings has on fire spread was verified,(4)an efficient city data acquisition technique by a stereo picture was proposed.
