| dc.description.abstract | Because of the convenience and mobility of motorcycle, it has become the popular traffic tool in low and middle-income households in Taiwan. According the report of statistics of Ministry of Transportation, Executive Yuan, the number of registered motorcycles increased annually, with economic and environmental development the masses continue growth in motorcycle demand. Taiwan is a densely populated country, there are shortage of supply of parking spaces in urban area, so that each household in average has at least one motorcycle. Since the motorcycle accidents occupy high proportion of total traffic accidents, we should pay more attention to the impact of motorcycle accidents.
For the data set of motorcyclist injured or not in the accident, we calculate the association between response and explanatory variables, and apply CHAID to find the important variables. Further, we establish the logistic regresstion model for those important variables selected in CHAID. For the data set of motorcyclist in accident who die within 30 days, we build up an appropriate loglinear model to find out the characteristic of a fatal accident. Finally, we propose some sugguestions to improve what we observe in this study.
