Transit Oriented Development (TOD) is a planning model that was introduced by Calthorpe (1993) in the United States. However, it has been applied in different international contexts: in high density urban environments (Asia) but also in medium density urban environments like in Australian cities (Perth, Brisbane) and in Canadian cities (Vancouver). The TOD concept is understudied in Europe. In this paper we analyse TOD-like projects using TOD criteria measurement – like the density of the built environment, the quality of public spaces, accessibility to public transport, the mix of land-uses – to determine the kind of TODs they are. Those criteria have been selected according to the literature on the topic. For this analysis of TOD projects, we use geospatial data for the Paris metropolitan region. After the identification of typical Transit Oriented projects, the objective is to analyse recent TOD case studies (e.g., ZAC Pleyel project in St-Denis). The aim is to understand why some criteria are more challenging than others to implement in practice. The qualitative data has been collected through semi-structured interviews with urban stakeholders. The overall aim of the paper is to provide planning recommendations for best practices of TODs in a high density environment such as the Paris metropolitan region.
