Abstract:
High number of traffic accidents in Iran and its rate which is well above the world's average is a major issue of concern. The results of recent researches show a direct relation between survival rate of traffic accidents' injuries and the Emergency Response Time (ERT). The main objective of this research is to analyze different aspects of ERT in Tehran, Iran and to compare these results with the International standards. This study intends to compare the selected routes by ambulance drivers with the shortest paths recommended by EMME/2. Results of analysis show that when the travel time between accident scene and the emergency dispatch center is less than 8 minutes, the possibility of choosing the shortest path by the ambulance drivers will increase substantially. The results of this study also demonstrate there is a critical difference in the transport time with respect to the world’s standards, which maybe as a result of not utilizing all of the available hospitals. Furthermore a model was used to find the optimized locations of emergency medical service stations based on the minimum and current number of available ambulances
