Abstract
Using the police command center hotline ―110. as a channel, this study performed a call back interview to ask the accident reporting motorists about their perceptions on the quality of police service. A concept of fuzzy logic was introduced to measure the qualitative questions characterized with fuzziness. A total of 254 accident reporting motorists in Taipei City were interviewed. The results revealed that no less than 80% of the respondents would be satisfied and no more than 20% of them would be dissatisfied if the police response time could stay within 5 to 10 minutes and service time within 20 to 35 minutes. Both satisfaction and dissatisfaction to the police service time for A2-type accident (injury) were significantly longer than that for A3-type accident (property damage). According to our findings, the current practices of police deployment and accident investigation in Taipei City should be reexamined.
