This paper focuses on the use of vague discourse in planning. Early contributions identified vagueness as a ‘problem’ to be solved so as to avoid potential misunderstandings and conflicts. This paper adopts the complementary point of view whereby vagueness can also be a ‘resource’, that is, a strategy used by actors in adverse circumstances. A systematic analysis of the texts and illustrations of 36 urban transport plans shows that vagueness is an essential ingredient. It is used mainly as a way to hedge against unwanted public commitments in the context of major uncertainties and tension between actors.

当模糊性是计划参与者的战略资源时

本文着重于在规划中使用模糊的话语。早期的贡献将模糊性视为要解决的“问题”，以避免潜在的误解和冲突。本文采用了补充的观点，即模糊性也可以是一种“资源”，即行为者在不利情况下使用的策略。对36个城市交通规划的文字和插图进行的系统分析表明，模糊性是必不可少的要素。它主要用作在重大不确定性和参与者之间紧张关系下对付不必要的公共承诺的一种方式。
