近年来，轨道交通规划和设计在美国获得了发展势头，因为它们在促进城市通勤方面具有减少道路交通的潜力。由于轨道交通规划、设计和建设各个阶段的决策过程非常复杂，项目重新规划和成本超支的变化可能会在后期阶段发生，例如项目进入建设阶段。由于目前可用的分析和优化工具无法自动化轨道交通规划和设计过程的每一步，因此需要遵守环境法规进一步加剧了这一问题。本文从项目重新规划、延误和成本超支的角度讨论了与铁路规划和设计相关的实际问题。作者研究了路线和车站位置优化以及规划和可行性研究的可用分析模型，并评估了其在实际项目中的实用性，受到各种设计和运营限制。作者提供了一些分析建模技术的假设的例子进行了讨论。本文最后讨论了一些计划中的项目和未来的研究方向。
Rail transit planning and design have been gaining momentum in the United States in the recent years due to their potential to reduce road traffic in facilitating urban commuting. Due to the complexity in the decision-making process at various stages of rail transit planning, design, and construction, changes in project re-scoping and cost overruns are likely at later stages, such as when a project proceeds to construction. The need for compliance with environmental regulations further exacerbates the problem since currently available analytical and optimization tools are not capable of automating every step of the rail transit planning and design processes. This paper offers a discussion of the practical issues related to rail planning and design in view of project re-scoping, delays, and cost overruns. The authors examine available analytical models for route and station location optimization as well as planning and feasibility studies, and assess their practical applicability in real-world projects, subject to various design and operational constraints. The authors offer a discussion of some analytical modeling techniques on hypothetical examples. The paper concludes with the discussion of some planned projects and directions for future research.
