Tourism flows to large cities have increased drastically in the past few years. The Alfama neighbourhood in Lisbon (Portugal) is facing major changes with respect to land uses, demographic features and social appropriation patterns in public spaces, caused by the intensification of tourism. The consequences of new emerging economic and symbolic values have rapidly given rise to a scenario of touristification and gentrification in the neighbourhood. In order to address such complexities, sustainable urban planning can benefit from real-time data sources that can represent the tourism flows in spatial and temporal perspectives. The research question allows Twitter to be used as an emerging data source and for analysing spatial patterns and content, based on two sample groups: residents and tourists, and their interpretations about the use of space for leisure activities. The research method is based on an analysis of two years of geotagged tweets in the city of Lisbon, differentiating between tourist and resident users, and, in a subsequent step, in the Alfama neighbourhood. The spatial distribution analysis and the content analysis have revealed not only spatio-temporal activity patterns but also emotional responses to new trends in urban tourism uses, consumption and perception of an increasing tourism pressure in Alfama. The results are relevant in the field of tourism and sustainable urban planning.

The Olympic Games have a huge impact on the cities where they are held, both during the actual celebration of the event, and before and after it. This study presents a new approach based on spatial analysis, GIS, and data coming from Location-Based Social Networks to model the spatiotemporal dimension of impacts associated with the Rio 2016 Olympic Games. Geolocalized data from Twitter are used to analyze the activity pattern of users from two different viewpoints. The first monitors the activity of Twitter users during the event—The arrival of visitors, where they came from, and the use which residents and tourists made of different areas of the city. The second assesses the spatiotemporal use of the city by Twitter users before the event, compared to the use during and after the event. The results not only reveal which spaces were the most used while the Games were being held but also changes in the urban dynamics after the Games. Both approaches can be used to assess the impacts of mega-events and to improve the management and allocation of urban resources such as transport and public services infrastructure.

In their national contexts border areas are peripheral and generally located in sparsely populated territories, far from large urban agglomerations. Higher transport costs are therefore incurred by residents and businesses in these areas when connecting with central markets, and this reduces their accessibility to economic activities and more specialized services. Investment in transport infrastructure is a policy instrument used to lessen the remoteness of border regions and increase their accessibility. This study analyses the accessibility of the border regions of Portugal, Spain and France between 1960 and 2010. Accessibility of border regions is compared to national averages and between national and international connections. The market potential and daily accessibility indicators have been selected for this analysis using a joint approach that offers a complementary view of the changes, which occurred over this period. Given their peripheral condition, border regions are generally less accessible than the national average. However, results show that transport investments over this 50-year period helped to improve the accessibility conditions of border regions. Most interesting is the fact that many border regions have increased their accessibility levels at a higher pace than the national average, thereby reducing the accessibility gap with the rest of the country. Border regions suffer from lower accessibility to international destinations partly due to poorer network conditions. However, results show that during this period the greater changes largely benefited international accessibility. Differences between the two selected indicators offer a more complex and richer picture of the evolution of the accessibility of these border regions.

Social network data offer interesting opportunities in urban studies. In this study, we used Twitter data to analyse city dynamics over the course of the day. Users of this social network were grouped according to city zone and time slot in order to analyse the daily dynamics of the city and the relationship between this and land use. First, daytime activity in each zone was compared with activity at night in order to determine which zones showed increased activity in each of the time slots. Then, typical Twitter activity profiles were obtained based on the predominant land use in each zone, indicating how land uses linked to activities were activated during the day, but at different rates depending on the type of land use. Lastly, a multiple regression analysis was performed to determine the influence of the different land uses on each of the major time slots (morning, afternoon, evening and night) through their changing coefficients. Activity tended to decrease throughout the day for most land uses (e.g. offices, education, health and transport), but remained constant in parks and increased in retail and residential zones. Our results show that social network data can be used to improve our understanding of the link between land use and urban dynamics.

The accessibility of a certain place can evolve either as the direct result of transport changes or as a consequence of the spatial redistribution of economic activities. These two factors are often indistinguishable—especially at regional level—since improved infrastructure stimulates relocation of activities. Moreover, infrastructure investment choices tend to follow population and economic activity patterns, distorting the cause and effect relationship between infrastructure and accessibility even further. The methodology and results presented here decompose the impact of both factors in terms of accessibility using Spanish data between 1960 and 2010. During this period, Spain experienced profound changes in transport infrastructure and economic activity. We use the potential accessibility indicator and resort to index number theory to disentangle the contribution of transport infrastructure from that of land-use changes. Detailed historical data on road infrastructure and population is used to represent the transport and land-use components of accessibility. Our results show that changes in transport infrastructure had a relevant impact on accessibility, as expected, but changes in the spatial distribution of population had an even greater effect. This outcome may be used as an argument for sustainable accessibility, a concept that advocates integration of transport and land use planning.

This article reviews innovation of the European transport industries. It combines a quantitative analysis of the R&D investment of manufacturers of transport equipment, transport service providers and the constructors of transport infrastructure for the years 2008 and 2011 with a qualitative assessment of their incentives to innovate. The latter takes into account sector-specific innovation systems, their distinct market environments and the products and services produced. The findings show that, although the transport sector as a whole is the largest industrial R&D investor in the EU, there are important differences in the level of innovation activities carried out by the highly heterogeneous sub-sectors. These differences seem to be of systemic nature: they are found consistently in the quantitative analysis and the theoretical considerations. The result is highly policy-relevant as it indicates that policies targeting innovation in transport need to take into account the specific innovation capacities of the various sub-sectors

This guide provides regions with information and guidelines useful for the development of smart specialisation strategies (RIS3) in transport. The guide follows the six steps for Smart Specialization with a special focus in transport. The six steps include the analysis of the regional context and potential for innovation, the discussion of governance structure, the development of a shared vision about the future of the region, approaches for the selection of transport related priorities for regional development, policy mixes and options for the integration of monitoring and evaluation mechanisms. The recommended process consists of a bottom-up analysis of regional capabilities of the industry and scientific community that needs to be aligned with national and European objectives. At the European level, the Strategic Transport Technological Plan (STTP) identifies ten innovation areas that will be extremely important for the future competitiveness of the transport sector. The guide also analyses different innovation area in the context of RIS3 methodology, showing specific examples and roadmaps on how these could be implemented in the regional innovation strategies. Finally tools are offered to analyse the innovation potential, performance and priorities in the transport sector, such as data and indicators regarding regional transport innovation, as well as methodologies to analyse innovation capabilities of European regions.
