This project explores the promotion of green mobility and sustainable transportation in urban environments, with a specific focus on cycling as a viable alternative. The aim is to address the challenges associated with car-centric societies and shift towards human-centric cities that prioritise eco-friendly modes of transportation. The project begins by analysing the existing infrastructure and poli-cies surrounding cycling and green mobility. It identifies some of the barriers and limitations that hinder the widespread adoption of sustainable transportation practices. The outcomes of workshops and collaborative efforts are highlighting the iterative nature of the pro-ject and the importance of continuous learning and refinement. Building upon these insights, the project proposes a range of interventions and strategies to encourage cycling and promote green mobility. Through prototyping and testing, the project demonstrates the effectiveness of these interventions and uncovers the “dark matter” - hidden challenges and potential opportunities - that influence the success of sustainable transportation initiatives. The project highlights the importance of creating better environments, implementing traffic education in schools, and developing clear feedback loops between the city and its citizens. It emphasises the need for a shift in policies, laws, and institutions to enable sustainable transportation practices and create a positive im-pact on urban environments. Ultimately, the project serves as a call to action for policymakers, urban planners, and citizens to work together towards the common goal of transforming cities into sustainable, people-centred spaces that prioritise eco-friendly transportation options.
