Obstructions for smooth running of ambulances in emergency motion seem to increase as the traffic condition becomes worse and the frequency of action increases more. It needs to clarify what and how obstructs the running of ambulances and what countermeasures need to improve the running speed of ambulances in emergency dispatch.We analyze some regional statistical data in Nagoya City to make clear whether or not the running speed of ambulance is explainable by regional characteristics. As the result of multiple correlation analysis, there is high correlation between the regional characteristics and the speed of ambulance, and the shortage of traffic facilities is the main factor of obstruction. We moreover make clear the regional characteristics within the jurisdiction area of the ambulance by means of principal component analysis, and discuss the countermeasures how to improve the running speed of ambulances.
