The rise of concepts such as the 15-minute-city represents the growing importance of accessibility by active mobility. In order to promote accessibility, accessibility instruments are developed that have substantial potential to assist practitioners in decision making processes. Therefore, this research starts with an up-to-date overview on the suitability of accessibility instruments when planning for active mobility. It was found that accessibility instruments were significantly further developed in the last few years and there is a rising number of tools that contain novel features. However, it was identified that there is a clear lack of tools specifically designed for modeling active mobility that are open source, include interactive scenario building, and can easily be transferred to new study areas.

Therefore, an interactive accessibility instrument named GOAT (Geo Open Accessibility Tool) was developed, which is open source, transferable, and has an easy-to-use web interface. This instrument has been developed following an iterative software development process in close cooperation with practitioners from three municipalities in the region of Munich, Germany. The practitioners tested the tool independently in numerous workshops in order to provide feedback, which was integrated into the development. Furthermore, the tool was tested and transferred to more than 20 German municipalities, the City of Bogotá (Colombia) and Matosinhos (Portugal). First results show that the collaborative and open development process produced a user-centric solution, which bears the high potential to make planning for active mobility more effective and efficient.

诸如15分钟的城市之类的概念的兴起代表着主动出行带来的无障碍获取的日益重要的意义。为了促进无障碍获取，人们开发了具有巨大潜力的无障碍获取工具，可协助从业人员进行决策。因此，本研究从规划主动出行时对无障碍工具适用性的最新概述开始。发现无障碍工具在过去几年中得到了极大的发展，并且包含新颖功能的工具数量也在不断增加。但是，已经确定明显缺乏专门为主动移动性建模而设计的工具，这些工具是开源的，包括交互式场景构建，并且可以轻松地转移到新的研究领域。

因此，开发了一种名为GOAT（Geo开放可访问性工具）的交互式可访问性工具，该工具是开源的，可转让的，并且具有易于使用的Web界面。在与德国慕尼黑地区的三个城市的从业者密切合作下，经过反复的软件开发过程，开发了该仪器。从业人员在众多研讨会上独立测试了该工具，以便提供反馈，这些反馈已集成到开发中。此外，该工具已经过测试，并已转移到德国的波哥大市（哥伦比亚）和马托西纽什（葡萄牙）的20多个城市。最初的结果表明，协作和开放的开发过程产生了以用户为中心的解决方案，具有使主动出行计划更加有效和高效的巨大潜力。
