公路发展和管理模型（HDM-4）是一个评估公路运输基础设施投资方案的软件系统。在世界范围内，HDM-4模型最常用作可行性研究的基础，在可行性研究中，道路项目从经济可行性方面进行评估。基于HDM-4的更全面的评估类型是网络评估，它评估整个道路网络，以帮助决策者进行道路投资的战略规划和/或合理的道路工程计划的定义，无论是否有预算限制。网络经济评估是该模型最具挑战性的用途，但考虑到通过比较各种项目备选方案并在预算约束下进行优化来实现运输成本的潜在节省，这一努力是合理的。本技术说明介绍了作者将HDM-4及其前身公路设计和养护标准模型（HDM-III）应用于发展中国家公路网战略规划评价的经验，目的是为参与战略规划活动的读者提供建议和工具。评价的目的、方法本身、投入要求、挑战和向决策者提交结果的方式都依次得到审查。
The Highway Development and Management Model (HDM-4) is a software system for evaluating options for investing in road transport infrastructure. Worldwide, the HDM-4 model is most commonly used as a basis for feasibility studies, in which a road project is evaluated in terms of its economic viability. A more comprehensive type of evaluation based on HDM-4 is a network evaluation, which assesses an entire road network to help decision makers in their strategic planning of road investments and/or the definition of a rational road works program, with or without budget constraints. A network economic evaluation is the most challenging use of the model, but the effort is well justified given the potential savings to be achieved on transport costs by comparing various project alternatives and performing an optimization under budget constraints. This technical note presents the author's experience applying HDM-4 and its predecessor, the Highway Design and Maintenance Standards Model (HDM-III), to road network strategic planning evaluations in developing countries, with the objective of providing recommendations and tools to the readers who are involved in strategic planning activities. The purpose of the evaluations, the methodology itself, the input requirements, the challenges, and the presentation of results to decision makers are each reviewed in turn.
