How the location of urban consolidation and logistics facility has an impact on the delivery costs? An accessibility analysis

Urban consolidation is a popular subject in city logistics. Moreover, public authorities need adapted decision support methods to analyse the interaction between their land-use choices and the transformations in trip behaviour, for both personal and commercial trips. This paper proposes a simulation method to carry out a land-use and transport interaction analysis based on the notion of accessibility, and applies it to the real urban network of Lyon. First, a literature review on accessibility and simulation of goods flows is made. Second, the proposed method is presented on the form of a sequential procedure. First, a demand generation model estimated the weekly number of demands to deliver to each customer, to what we convert the generated number of deliveries into a daily number of freight transport demands including a quantity of goods to deliver and a customer, via an empirical procedure. Then, a spatial analysis to choose the most suitable sets of potential logistics facilities is proposed. Finally, each platform is associated to a distance-based accessibility indicator. Computational results are presented and discussed. Finally, recommendations to public authorities for their land-use policy assessment in terms of impacts on freight transport are proposed.
