旧金山湾区快速交通系统（BART）的票价套利研究
Transit Fare Arbitrage: Case Study of San Francisco Bay Area Rapid Transit (BART) System
摘要：
过境票价套利是指两个或两个以上的通勤者同意在旅行期间以总成本低于其他方式的方式交换车票的情况。这种套利行为使得定价效率低下的现象得以探索和利用，从而改进定价模型。在本文中，我们讨论了票价套利的基础知识，通过一个直观的定价框架，涉及人口密度。然后，我们分析旧金山湾区快速交通（BART）系统，以了解潜在的低效率。我们还在github.com/asifhaque/transit-arbitrage提供源代码和具有显著套利收益的成对行程的全面列表。最后，我们指出了一个统一的支付界面，为不同类型的交通系统。
英文摘要：
Transit fare arbitrage is the scenario when two or more commuters agree to swap tickets during travel in such a way that total cost is lower than otherwise. Such arbitrage allows pricing inefficiencies to be explored and exploited, leading to improved pricing models. In this paper we discuss the basics of fare arbitrage through an intuitive pricing framework involving population density. We then analyze the San Francisco Bay Area Rapid Transit (BART) system to understand underlying inefficiencies. We also provide source code and comprehensive list of pairs of trips with significant arbitrage gain at github.com/asifhaque/transit-arbitrage. Finally, we point towards a uniform payment interface for different kinds of transit systems.
