当城市快速路网发生交通事故时，紧急救护车迅速到达事故现场并将其送往医院是一项重要的救生活动。由于事故发生后的交通堵塞等原因，执行救生活动需要大量时间。因此，消防组织和城市高速公路组织应通过频繁执行事故发生时假设情况的救生训练，研究即使在发生交通堵塞时也执行提示救生活动的方法。然而，在城市快速路中实施救生活动在时间和成本上都存在困难。然后，在本研究中，我们使用作者开发的交通模拟系统，在城市快速道路上的即时救生活动进行了研究。具体来说，通过再现城市快速路发生交通事故和执行救生活动的情况，测量了应急车到达事故现场的时间。同时，我们利用黄金时间原则的概念来检验预期的救生效果，该原则显示了自受伤以来的通过时间与死亡率之间的关系，我们明确了目前救生活动的问题。此外，我们证明了一个救生的可能性，提高了缩短时间，紧急汽车进入高速公路。
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.
