摘要: | 在长途旅次使用高速公路比率逐年增加的情况下,缩短高速公路上事故排除时间系目前重要的课题。本研究收集101年11月至102年2月,大台中都会区国道1号与国道3号高速公路上,共1335件之交通事故资料:其中国道1号共933件,国道3号共422件。频率统计发现平均事故排除时间为19分钟,而事故排除时间的范围大多落在0分钟至35分钟之间,占全部事故的 94%。利用存活分析法中的Cox等比例危险模式,找出高速公路上事故排除时间的显着影响变数,并构建两者之关系。结果显示:在国道1号与国道3号上,事故后占用越多车道、涉及越多车辆以及受伤人数越多,皆与事故排除时间呈现正相关;晚上相较于白天事故排除时间也较长。是否需工务段出勤协助排除事故只在国道1号上呈现显着影响,且如需工务段协勤之事故排除时间较长。协助救护之管辖消防局与事故现场间之距离则在两条高速公路上皆显着与事故排除时间呈现正相关,亦即救护距离会影响事故排除时间。 The proportion of long-distance trips using freeways has been increasing over the years. Thus to shorten the clearance time of freeway incidents becomes an important issue. In this research, 1335 cases in total were collected of accidents from Sun Yat-Sen Freeway and Formosa Freeway from November, 2012 to February, 2013 around the Taichung Metropolitan Area, including 933 on Sun Yat-Sen Freeway and 422 on Formosa Freeway. The average accident clearance time is 19 minutes, with the majority ranging between 0 to 35 minutes, which accounted for 94% of the sample. The Cox proportional hazard model of survival analysis was used. On both Yat-Sen Freeway and Formosa Freeway, if an accident interferes more traffic lanes, involves more vehicles, or has more numbers of injuries, the longer the clearance time of freeway incidents occurs. Moreover, it needs longer clearance time if the accident happens at night than in daytime. It shows that the need of the Public Works Section attendance is significantly correlated with the clearance time positively on Sun Yat-Sen Freeway. It also shows that the distance from a closest Fire Department for ambulance assistance is significant and positively correlated with the clearance time of freeway incidents on both of the freeways. |
