当灾难发生时，许多人会给受灾地区的亲人打电话。其结果是，电话网络变得拥堵，人们很难相互联系。在一场大规模灾难之后，这种拥堵仍在继续。拥堵越早缓解，人们就越快、越容易联系到彼此。我们通过减少通信需求来实现这一点，而不直接限制呼叫持续时间。我们提出了一种拥堵控制方法，称为道路空间配给(RSR)方法(RSR最初是为交通设计的，根据车辆牌照或车牌号码的最后一位数字限制进入拥堵区域)。我们的RSR方法仅限制根据呼叫方电话号码的最后一位数进行呼叫的时间段(例如，只有电话号码以1结尾的人才能在XX：06和XX：12之间进行呼叫)。它不仅避免了对主叫方总数的限制，而且还提示人们在不受限制的情况下有意识地缩短通话时长。因此，它具有一种机制，可以在不直接限制通话时长的情况下改变人类的通信行为。这种有意识的意愿减少对灾难拥堵是有效的，因为没有对相同被叫方的重拨。这种呼叫持续时间的缩短反过来又减少了拥塞。实验结果表明，RSR方法使通话时长减少了30%。
When a disaster strikes, many people make calls to their loved ones in the affected area. As a result, telephone networks become congested, making it difficult for people to contact each other. This congestion continues in the aftermath of a large-scale disaster. The sooner the congestion is eased, the sooner and easier people can contact each other. We accomplish this by reducing communication demand without directly restricting call duration. We propose a congestion control method, called the road space rationing (RSR) method (RSR was originally designed for transportation and restricts access to congested areas on the basis of the last digit of a vehicle’s license plate or license number). Our RSR method only restricts the period in which to make a call on the basis of the last digits of calling parties’ phone numbers (e.g., only people with phone numbers ending in 1 can make calls between XX:06 and XX:12). It not only avoids restricting the overall number of calling parties but also prompts people to reduce their call duration consciously despite it being unrestricted. It thus has a mechanism to change human communication behavior without directly restricting call duration. This consciously willed reduction is effective against disaster congestion because there are no redials to the same called parties. This reduction in call duration in turn decreases congestion. Experimental results revealed that the RSR method reduced call duration by 30%.
