In China, with the accelerated urbanization and the rapid growth of urban population, potential urban emergency risk factors gradually increased. Therefore, how to forecast the urban emergency events seems to be important. This study elaborated the mechanism of catastrophe theory and grey forecast method, established the grey cusp catastrophe model according to further research. An empirical analysis on Chinese urban traffic accident forecast was made by this model through four indicators: the number of occurrences, the number of deaths, the number of people injured and direct economic losses. By operating the model with data from 2002 to 2006, the accuracy is verified. Based on data from 2002 to 2011, the model result shows that the next traffic accident occurrence catastrophe will occur in 2015-2016, the next death number catastrophe will occur in 2012-2013, the next injured number catastrophe will occur in 2018-2019, the next direct economic loss catastrophe will occur in 2014-2015.
