    This working paper offers an evaluation of the performance of the port of Marseille-Fos, an analysis of the impact of the port on its territory and an assessment of policies and governance in this field. It examines declining port performance over the last decades and identifies the principal factors that have contributed to it. The effect of the ports on economic and environmental questions is studied and quantified where possible. The value added of the port cluster of Marseille-Fos is calculated and its interlinkages with other economic sectors and other regions in France delineated. The paper outlines the impact of the ports? operations, and shows how their activities spill over into other regions than the one in which the port of Marseille-Fos is located. The major policies governing the ports are assessed, along with policies governing transport and economic development, the environment and spatial planning. These include measures instituted by the port authorities, as well as by local, regional and national governments. Governance mechanisms at these different levels are described and analysed. Based on the report?s findings, recommendations are proposed with a view to improving port performance and increasing the positive effects of the port of Marseille-Fos on its territory

    Clustering and Modeling of Network level Traffic States based on Locality Preservative Non-negative Matrix Factorization

    No full text
    International audienceIn this paper, we propose to cluster and model network-level traffic states based on a geometrical weighted similarity measure of network-level traffic states and locality preservative non-negative matrix factorization. The geometrical weighted similarity measure makes use of correlation between neighboring roads to describe spatial configurations of global traffic patterns. Based on it, we project original high-dimensional network-level traffic information into a feature space of much less dimensionality through the matrix factorization method. With the obtained low-dimensional representation of global traffic information, we can describe global traffic patterns and the evolution of global traffic states in a flexible way. The experiments prove validity of our method for the case of large-scale traffic network

    CHAPTER 4.2: APPLICATION OF URBANSIM IN PARIS (ILE-DE-FRANCE) CASE STUDY

    No full text
    This chapter presents the modeling and simulation works applying UrbanSimE in Paris case study. This is the most important application of UrbanSim worldwide with respect to the size of the region and of the project evaluated, data availability and complexity. The rich available data allowed us to make different econometric analyses and to implement several theoretical insights previously presented in this handbook. The model has been successfully used in an applied study concerning the Grand Paris project, which can be considered as the most important investment plan in the transportation system of the region since the construction of Paris subway network at the beginning of the 20th century

    Africapolis (English version): Urbanization study in West Africa (1950-2020)

    http://www.afd.fr/jahia/Jahia/lang/en/home/publications/NotesetEtudes/AfricapolisMore than 2,558 agglomerations have been identified on the ground, although only those with more than 10,000 inhabitants were classified as ”urban” to ensure that the definition was comparable across the region. On the other hand, using available statistical data, we identified 160,000 towns and villages. This morphological database was cross-referenced with the results of the population censuses, starting with the present day and going as far back as possible given the sources available. The results of work of this kind can be extrapolated to the global level, with users benefiting from the heuristic advantages of such scaling. Part 1 sets out the documentary sources, definitions, and methodology used in the study, and makes comparisons with a range of earlier studies. Part 2 presents an analysis of the results. In parallel to the presentation of statistical data, the focus is on the processes and structures of urbanization. While urbanization in Africa is clearly evolving very rapidly, it is nonetheless important to understand that certain structures, put in place at different times or the result of simple, and often misunderstood, urban system's characteristics (for example, hierarchical distribution or the Law of Metropolization), can cause considerable inertia. Understanding the nature of this inertia allows us to better predict what will change and where it will change

    Land-Use Transport Interaction: State of the Art

    Get PDF
    This paper investigates innovative approaches to the integration of land-use and transport planning in urban regions. Engineering, economic and social-science based theories and empirical studies are analyzed regarding their ability to explain the interaction between land use and transport - that land use determines traffic flows and that transport infrastructure changes land-use patterns. In addition, this paper provides an overview of the state of the art of computer models for the simulation of land use and transport. Based on these theories and models the effectiveness of policies to influence land use and transport in urban regions is assessed.Urban location theory, transportation research, land use- transport interaction, urban simulation modeling, location choice

    Material flows and local economic structure: port-region linkages in Europe, Japan, and the United States

    Get PDF
    The main goal of this paper is to identify mutual influences between the specialization of traffics passing through seaports and the socio-economic characteristics of their surrounding regions. While the contemporary era is marked by the fading spatial fix of value chains as notably seen in the dereliction of port's local linkages, a systematic and comparative empirical analysis remains lacking. One main reason is the absence of internationally harmonized data on the precise spatial distribution of port-related hinterland flows as well as inadequacies between the volume and the value of freight. This research proposes to overcome such difficulties based on a common set of 21 traffic and socio-economic indicators covering 189 port regions in Europe, Japan, and the United States. Main results underline invariants as well as local specificities in the functional and spatial affinity between certain traffics and certain types of regions. While large urban and financial centres tend to polarize most valued, diversified, and weighty traffics, rural regions generally concentrate agricultural goods and minerals, and industrial regions concentrate combustibles and metals. Beyond the simple reflection of local demand, such results confirm the path-dependency of the association between material flows and regional economic development. A typology of port regions is proposed in order to map the distribution of port regions and to zoom on specific local conditions
