ABSTRACT Class I railroads in North America collectively invested USUS$11.2 billion to comply with a U.S. federal mandate to deploy positive train control as a form of train protection system. This amount dwarfs the potential savings from accidents the technology could prevent. Therefore, railroads must seek additional benefits. This research contributes simple closed-form models to inform strategies that can leverage the technology deployment by estimating the annual additional net benefits, internal rate of return, and benefit-cost ratio needed for a desired payback period.

用于评估铁路技术投资的封闭式模型

摘要 北美的 I 类铁路总共投资了 112 亿美元,以遵守美国联邦的规定,将积极的列车控制作为列车保护系统的一种形式。这一数额使该技术可以预防的事故所带来的潜在节省相形见绌。因此,铁路必须寻求额外的利益。这项研究提供了简单的封闭形式模型,通过估计预期投资回收期所需的年度额外净收益、内部收益率和收益成本比,为可以利用技术部署的策略提供信息。
