Abstract: 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 .
