There is human error as a common factor of many traffic accidents. This study is aimed at evaluate from a nasal skin thermogram measured with an infrared thermography device about a change of physiology psychological condition of a driver. We measured a time change of difference of temperature of frontlet skin temperature and nasal skin temperature that can measure condition of sympathetic system / parasympathetic system indirectly with the infrared thermography device which can measure in non-contact, low restraint, easily. The experiment measured quantity of physiology from brain waves, a heartbeat, an nasal skin thermogram with the driving simulation problem which made a limit for a driver in time. By performing comparison with quantity of subjectivity, quantity of meandering and driving action quantity and steerage corners to acquire at the same time, we evaluate physiology psychological condition of a driver at the time of driving under the time pressure situation. As a result, by giving time pressure, difference of temperature of frontlet skin temperature and nasal skin temperature showed a change. Greatest temperature displacement became big when raised a degree of difficulty of time pressure.
