Traffic congestion and air pollution continue to be serious concerns, especially in large cities, and going forward, this is not sustainable. Urban transport around the world is facing challenges, such as air pollution and inefficient use of resources, that often inhibit economic development. Simply building more roads cannot address such challenges. There is a need to integrate the urban infrastructure through smart connectivity. Smart mobility, as a vital cornerstone of a smart city, will potentially reduce traffic jams, commuting times, and road crashes and create an opportunity for passengers to customize their journeys. In fact, planning smart mobility solutions is among the top challenges for large cities around the world. It involves a set of deliberate actions backed by sophisticated technologies. The different elements and dimensions that characterize smart mobility are investigated to depict the overall picture surrounding the smart mobility domain. Additionally, the trends, opportunities, and threats inherent to smart mobility are addressed. There are four segments of smart mobility that are highlighted in this paper: intelligent transport systems, open data, big data analytics, and citizen engagement. These segments are all inter-related and play a crucial role in the successful implementation of smart mobility.

Strategic Environmental Assessment (SEA) is fairly well-established in Spain, informing decision-makers on the likely environmental consequences of their plans and policies. However, limited attention has been paid to the study of SEA effectiveness in Spain, particularly with regards to practitioner and stakeholder views. This paper aims to bridge this knowledge gap by gathering and examining views on SEA's participatory aspects, the performance of the procedural elements and the overall role of SEA in decision-making. The paper describes the legal implementation of SEA in Spain, and discusses current views on its effectiveness, grounded on the authors' own experiences.
