Today, the need for innovative sustainable development models is becoming more and more central in the international debate. The integration between land-use and transport in policy-making and planning is crucial for achieving sustainability, and Transit-Oriented Development (TOD) is reported to be one of the possible models, performing this integration. This thesis wants to describe the current trends in applying Transit-Oriented Development strategies, in eight European nations, and it also aims to understand how the Spatial Governance and Planning System (SGPS) of each country could affect, positively and negatively, future implementations of the model. Starting with an overview of today’s sustainability issues and their links with urbanisation and transport, the attention shifts to the TOD’s background, definition, examples, and recognition as a sustainable development model by the international scene.
