A highway traffic accident normally appears to be a random event, but also have its inevitability. Some potential factors hidden behind the appearance make such random events occur. There must be some relationship between the appearance and the factors of the accident. This paper will use expert investigation method to establish a check table to clarify the factors behind the appearances, find out the degree of contribution that such appearance made on reflecting the internal factors. Finally, combined with traffic accident statistics analysis on black-spots, calculate the scores of various causes. The higher score causes makes more effect for this black-spot.
