应急车辆延误情况调查及应对措施研究

因交通拥堵而造成的应急车辆救援延误导致悲剧事件频发。为了解应急车辆救援延误的情况并研究应对措施,以普通机动车驾驶者为对象进行问卷调查,针对驾驶者对应急车辆的认识和对应急车道的占用情况,驾驶者在驾驶过程中对应急车辆是否避让,以及避让方法进行调查。然后利用SPSS数据统计软件筛选出对驾驶者驾驶行为影响权重较大的特征变量,并基于Logistic模型建立了驾驶者特征与占用应急车道和避让应急车辆行为的模型。在此基础上提出相应的应对方案,利用Vissim仿真软件对解决方案进行仿真。结果显示:对有一定驾驶年龄并有本科以上学历的青壮年的驾驶行为对应急车辆延误有较大影响,且正确的避让方法能明显地减少应急车辆的行程时间。 

Investigation of Emergency Vehicle Delay and Response Measures

In recent years ,delays to emergency vehicles caused by congestion have led to frequent tragedies .In or-der to understand the reason of emergency vehicle rescue delays and to study the countermeasures ,this paper took ques-tionnaires on ordinary vehicle drivers about their understanding of the emergency vehicles ,the emergency lane occupancy , and the need to yield to the emergency vehicles .Next ,the paper screened out characteristic variables which affect the driving behavior greatly by using software SPSS ,and established the characteristics model of drivers and their behavior model in emergency lane occupancy and emergency vehicle avoidance based on Logistic regression .Then ,the appropriate response plans based on the results were proposed and the effect of the solution was simulated by simulation software Vis-sim .The results show that the driving behaviors of certain people have greater impact on emergency vehicle delays ,and that the correct avoidance method can significantly reduce travel time .
