摘要

在设计一个国家的公共交通网络时,人们可能希望将所有居民的旅行时间总和最小化。这相当于纯粹的功利主义观点,不涉及任何公平考虑,因为设计出的网络通常会有利于首都和/或大型中心城市,而将一些边缘城市甩在身后。另一方面,一种更公平的观点则允许一些人在外围城市之间旅行,而无需经过中心城市。我们定义了一个模型,提出了计算解决方案网络的算法,并报告了基于真实数据的实验结果。

Fair Railway Network Design
When designing a public transportation network in a country, one may want to minimise the sum of travel duration of all inhabitants. This corresponds to a purely utilitarian view and does not involve any fairness consideration, as the resulting network will typically benefit the capital city and/or large central cities while leaving some peripheral cities behind. On the other hand, a more egalitarian view will allow some people to travel between peripheral cities without having to go through a central city. We define a model, propose algorithms for computing solution networks, and report on experiments based on real data.
