Designers improve urban mobility solutions by investigating archetypal usage problems in existing mobility systems. User-centered design methods help accomplish this task, but lack effectiveness when not supported by appropriate tools. Here we posit that the use of a traveller-centred stimulus improves the effectiveness of travel problem generation. To test this hypothesis, an experiment is conducted with two control groups as a baseline for non-stimulated problem generation and two experimental groups that are provided with a traveller-centred stimulus. The two sets of groups are composed of one group of urban mobility experts and one group of non-experts. Results show that stimulated groups generate novel ideas with a greater variety covering most of the traveller experience dimensions than non-stimulated groups.

设计师通过调查现有出行系统中的原型使用问题来改善城市出行解决方案。以用户为中心的设计方法有助于完成此任务，但是如果没有适当的工具支持，则效率会降低。在这里，我们假设使用以旅行者为中心的刺激可以提高旅行问题产生的效率。为了检验该假设，进行了一个实验，其中两个对照组作为非刺激性问题产生的基准，而两个实验组则提供了以旅行者为中心的刺激。两组分别由一组城市交通专家和一组非专家组成。结果表明，与未刺激的群体相比，受刺激的群体所产生的新颖想法种类繁多，涵盖了大多数旅行者体验维度。
