When traffic accident occurs on urban expressway network, lifesaving activity with emergency car is important that promptly executes arrival at the scene of the accident and transportation to a hospital. The execution of the lifesaving activity requires a lot of time by the cause such as traffic jam after accident occurs. Therefore, the fire fighting organization and the urban expressway organization should examine method of executing prompt the lifesaving activity even when traffic jam occurred by frequently executing the lifesaving training that assumes situation when the accident occurs. However, it is difficult on both sides of time and the cost to actually execute lifesaving activity in urban expressway. Then, in this study, we examined prompt lifesaving activity in urban expressway by using the traffic simulation system developed by authors. Specifically, by reproducing situation that the traffic accident occurs on urban expressway and the lifesaving activity executes with the system, we measured the arrival time that emergency car arrives at the scene of the accident. And, we examined the expected lifesaving effects by using the concept of Golden Hour Principle that shows relation between passage time since the injury and mortality rate, we made the problem of the present lifesaving activity clear. In addition, we proved that a lifesaving possibility improved by shortening time that the emergency car enters in the expressway.
