It presents the main planning issues and challenges, and reviews the proposed methodologies. The chapter concludes with a discussion on perspectives for City Logistics and decision-support methodological developments.

Moreover, public authorities ’ actions in urban freight transportation policy and planning were limited to specific measures to deal with emergencies. With urban traffic increasing, and the raise of congestion not only in big but also in medium cities, some public administrations were confronted with the problem of urban freight distribution, that was managed traditionally only by the transportation carriers. In the 90’s and the beginning of the 21 th century, with the contribution of public administrations and other support funds, several studies and pilot tests have been made to learn how to organise urban freight distribution in order to decrease traffic and pollution derived from this sector. Most of these studies are oriented to support public authorities in decisions related to ...

Inspired by an application in a medium-sized city in Latin America, this paper develops a bi-objective mixed linear integer programming (MILP) model to locate different types of urban logistics spaces (ULS) for the configuration of a two-echelon urban distribution system. The objective functions seek to minimize the costs associated with distance traveled and relocation, in addition to the costs of violation of time windows. This model considers heterogeneous transport, speed assignment, and time windows. For experimental evaluation, two operational scenarios are considered, and Pareto frontiers are obtained to identify the efficient non-dominated solutions to select the most feasible ones from such a set. A case study of a distribution company of goods for supermarkets in the city of Barranquilla, Colombia, is also ...

This purpose of this article is to define, on the basis of a detailed analysis of the literature, a grid for interpreting and a dashboard for evaluating the sustainable performance of pooled delivery systems. Firstly, an analysis of the main works on the subject is proposed, regarding three complementary aspects: organisational efficiency, logistic performance and the evaluation of urban logistics projects. Then, the method for defining the dashboard derived from a collaborative decision-aid approach is proposed. Lastly, the dashboard is described and commented followed by conclusions and the outlook for further developments in view to a practical application of the approach.

It is applied to a real urban corridor: The Lafayette Avenue in Lyon (France). The framework combines traffic states with stochastic and microscopic freight demand generation model, i.e. the delivery movements and the delivery duration. Cooperative and competitive scenarios are considered. Impacts of goods delivery have been captured in a traffic evaluation model. The results of these configurations' assessment are discussed. Finally, practical implications for transport planners are highlighted.

First, the paper overviews the background, sets the context and motivates the research. Second, it presents the proposed methodology, which combines an FTG model, two accessibility indicators and a linear regression analysis to assess the relationships between freight trip demand and a set of socio-demographic variables including accessibility. The FTG modelling framework, adapted from previous works, allows estimating the number of freight trips with a small amount of standard data, even when no surveyed data is available. The two gravity accessibility indexes, one potential and one exponential, are defined in the continuity of recent freight accessibility works. To those indicators, a set of socio-demographic variables, including population, area or a zone (or density), are introduced. The relationships between FTG and all those variables are assessed via standard linear r...

Design/methodology/approach – First, a synthesis of the main works on the subject is proposed to provide a common grid of economic, environmental and social/societal indicators for sustainable supply chain management (SSCM), after which the method for defining the dashboard is presented. This method is derived from a collaborative decision-support approach and applied to a panel of operational logistics managers. Using a co-constructive method, a group of experts is consulted first separately, then by small groups and then a group restitution and consensus search process is made to find an agreed-upon set of indicators. Findings – The results show a difference between the in...

The authors identify information sharing as the critical factor in reasoning that occurs as stakeholders along the supply chain collaboratively make decisions. However, a shared conceptual model is required for determining what information must be shared. Their model identifies five elementsin information system management related to shared logistics projects: the enterprise‘s solutions (for each stakeholder and for the entire reasoning community), their deals, sharing management, organizational features and information and communication technologies related to the management of shared information. Moreover, the main accelerating and limitating factors are overviewed.The chapter illustrates the applicability of the model with a case study on the distribution of newspapers in France.
