International audienceIPSS are popular in different fields of transport, mainly for personal use (car-sharing, bike-sharing). Their usage in urban goods transport is not still generalized but those systems present a good potential. This paper proposed to assess and analyze four different scenarios for urban goods transport to compare IPSS configurations to a business as usual situation, in terms of environmental impacts. Those impacts will be estimated via a life cycle analysis (LCA) method. First, the four scenarios are presented. The first scenario is the reference one, i.e. the business as usual situation. The other three scenarios represent possible IPSS configuration, i.e. a vehicle leasing system, a vehicle sharing system and an urban consolidation system. Second, the methodology for scenario assessment using LCA is described, and the main proposed indicators defined. Third, the main results of the scenario assessment are presented, analyzed and discussed. Finally, future researches are proposed

We compare the spatial logics of three logistics locations in the Paris region: parcel service terminals, distribution centers and inland ports. Using census of these locations and mapping our results, we have documented the diversity of logistics facilities. On the one hand, parcel service terminals and distribution centers are facilities dependant on the road accessibility and built by the corporate real estate market. On the other hand, inland ports are the outcomes of infrastructure policies and industrial practices. The diversity of logistics sites reveal the complexity involved in drawing up and implementing a logistics planning project on a metropolitan scale

Résumé Dans cet article, nous proposons d’identifier les évolutions de localisation des agences de messagerie en Île-de-France et de discuter des impacts de ces évolutions sur les mouvements de marchandises et sur les politiques locales. Nous présentons le phénomène d’étalement logistique (déplacement des plates-formes logistiques vers les banlieues parisiennes de façon plus dispersée que polarisée) qui a caractérisé ces établissements, des années 1970 jusqu’à ce jour. Nous prenons l’exemple des agences de messagerie, qui sont les terminaux servant à organiser les tournées urbaines du ramassage et de la distribution des colis. Le phénomène centrifuge de la localisation des agences de messagerie est illustré par des cartes ; une analyse centrographique a été réalisée afin de quantifier le desserrement moyen de ces agences entre 1974 et 2010. Nous utilisons l’outil du bilan carbone (le calcul des émissions de CO 2 d’une activité) pour comparer les émissions de CO 2 dues au desserrement logistique et les économies d’émissions permises par la politique de la Ville de Paris en faveur d’espaces logistiques urbains. Nous examinons, enfin, l’échelle régionale pour évaluer la pertinence et la faisabilité d’une politique d’aménagement des équipements logistiques franciliens.

The business to consumer distribution services (B2C), mainly related to ecommerce, know nowadays a real boom that is sometimes accompanied by fractures. To better understand this fast-changing situation and support researchers and practitioners, this chapter proposes a scenario assessment analysis focused on the new B2C strategy trends and the joint coordination of e-commerce stakeholders to better optimize consumer's delivery flows. First, the two main logistics solutions adopted by online retailers are introduced. Second, the main customer's delivery services in France are presented. The proposed scenarios take into account the relations between urban development and B2C logistics schemes. Finally, the scenario assessment method is introduced then environmental impacts are estimated and analyzed each scenario.
