This paper introduces a new measure of Roman roads that has been constructed for the Italian territory. The measure computes the length in kilometers of Roman roads at different administrative and territorial levels (NUTS, Local Labor Systems, grid cells), and contributes to the literature on historical infrastructures, providing a new precise measure to use for empirical purposes and easy to extend in all those territories where Roman roads have been constructed. From a mere econometric point of view, the index allows to capture the intensity of the treatment, providing an alternative empirical strategy for all those cases where the simple binary treatment cannot be performed.

本文介绍了一种针对意大利领土建造的罗马道路的新措施。该度量计算了不同行政和领地级别（NUTS，本地劳工系统，网格单元）的罗马道路长度（以公里为单位），并为有关历史基础设施的文献做出了贡献，提供了一种用于经验目的且易于扩展的新的精确度量。在所有修建了罗马道路的地区。从单纯的计量经济学角度来看，该指数可以捕获治疗的强度，从而为无法执行简单的二元治疗的所有情况提供替代的经验策略。
