The purposes of the study were to identify hand-held mobile phone use trends for Michigan and to compare safety belt use between users and nonusers. Mobile phone and safety belt use was investigated by a direct observation survey of drivers at intersections in Michigan. Data were weighted to calculate mobile phone use and safety belt use rates statewide. The study showed 2.7% of Michigan drivers were using a mobile phone at any given daylight time. Safety belt use of current mobile phone users was significantly lower than those not using mobile phones.
该研究的目的是确定密歇根州手持移动电话的使用趋势,并比较使用者和非使用者的安全带使用情况。通过对密歇根州各十字路口的驾驶员进行直接观察调查,研究了移动电话和安全带的使用情况。对数据进行加权处理,以计算全州范围内的移动电话使用率和安全带使用率。研究表明,在任何给定的白天时间,密歇根州有2.7%的驾驶员在使用移动电话。当前移动电话使用者的安全带使用率显著低于未使用移动电话的人。
