　　Taiwan Railway is one of the important domestic intercity transportation systems. “Safety” is the first priority for transporting operations. However, over emphasize “Safety First” may reduce reasonable and objective investigation opportunity for “Safety Risk” To admit the nature of transporting activities with safety risk and to manage scientifically has been popularly facilitated in advanced countries. Others worthwhile to be noted are the balances between safety and invested amounts for safety equipment. In another word, besides to keep the risk low, the invested dollar amounts for safety equipment should not exceed either.

　　The purpose of this research is to analyze the safety risk concept applied in Taiwan Railway operating safety management. To define “risk” as “ Taiwan Railway’s accidents rate times accidents’ results (the severe degree)” according to the characteristics of Taiwan Railway operating safety. Further research subjects are to summarize Taiwan Railway’s accident information during 1996 to 2000, then categorize “death and injured accident” and “malfunction accident”.

　　This research analyzes safety risk’s value and risk contribution rate of “death and injured accident” and “malfunction accident”, and to evaluate “individual safety risk index” of “death and injured accident” according to the “equal to death” concept. After studied and analyzed the data, results are per million traveling times carried by Taiwan Railways, caused average 1.075 person death. The number is shared by “passanger”12.91%,“employees” 0.62%, and “the third party” 86.47%. Besides, there are also evaluations for “social safety risk index” of “major accident, which is numbered death accidents”, according to accident F-N curve.
