Abstract

The 9th International Conference on City Logistics, Tenerife, Iles Canaries, ESPAGNE, 17-/06/2015 - 19/06/2015; The aim of this paper is to study the location of the parcel industry, and its place in the spatial organization of logistics activities in the Paris Region. In particular, we wish to compare the location of the parcel industry to the location of other logistics activities. In order to do this, we review in part one the existing factors that determines the location of logistics activities. We use this literature review to draw initial conclusions on the distinctive characteristics of the parcel industry. In part two, we use existing data on the location of establishments in the Paris Region to study the dispersion of the parcel industry compared to the dispersion of other logistics activities. Finally, in part three, we provide a partial explanation for this difference: a spatial hysteresis of the big stakeholders of the parcel industry, and the emergence of innovative logistics solutions.

Abstract

International audience; Modeling transportation systems is strategic to evaluate urban development projects by providing traffic estimates and social, economic or environmental impacts. This paper puts forward an analysis grid highlighting Travel Demand Models (TDMs) characteristics and specificities to spell out the modeled mobility aspects and their operational capacities. This grid is then applied on 5 operational models used in the Paris region.In order to build this analytical framework, the standard model structure based on the supply, the demand, the mobility uses and their impacts is assessed. The proposed grid is articulated around the spatio-temporal frame, the demand, the transportation modes and services supply, and the mobility uses representations. Travel demand representation is treated in-depth by focusing on mobility decisions modeling. A final analytic table comparing Paris region models highlights the different mobility aspects revealed by each and discusses their specificities and their link to the TDMs’ operational uses.

Abstract

International audience; In the last few years, the issue of the location of logistics activities emerged in the literature, in Europe and in the United States, especially from the perspective of logistics spatial dynamics as logistics sprawl. These issues of spatial dynamics question urban policies, because they underline the lack of interest in freight in the planning process. Indeed, one of the major issues in planning logistics facilities is the lack of a good understanding of the logistics sector: it is difficult to guide public action in the absence of detailed and precise data. The great heterogeneity of logistics facilities is often underestimated by public policies. The visibility of some sectors in public policies or academic literature, as parcel industry or e-commerce, hides other sides of logistics as an industry sector. With this paper we underline differences in the location of facilities, which translates into a difficult implementation of public policies to regulate logistics sprawl in the case of the Paris region. This paper studies precisely the location of the warehouses and terminals, and their place in the spatial organization of logistics facilities in the Paris Region. In particular, we compare the location of mass retail and wholesale trade facilities, logistics provider's facilities and parcel's industry facilities. Document type: Article
