Abstract
Urban freight transportation constitutes both an extremely important and a rather disturbing activity. Increasingly, one observes efforts to measure and control freight movements within city centers. We introduce a possible organizational and technological framework for the integrated management of urban freight transportation and identify important associated planning and operation issues and models. We then describe a formulation for one of these problems, the design of the proposed logistical structure, and discuss algorithmic and implementation issues. Our model city and challenge is Rome. 2004 Elsevier Ltd. All rights reserved.

6. Conclusions and perspectives
The transportation of goods constitutes both an extremely important and an increasingly disturbing activity taking place in urban areas. Freight movements support most city-based activities, while negatively impacting on the quality of life in cities through significant contributions to the levels of congestion, noise, and pollution. There is therefore a need for new methods and tools to study, plan, and control freight-related traffic. Integration and city-wide views are key factors of success if one desires to simultaneously reduce congestion and increase mobility, while not unduly penalizing the city center commercial activities so as not to empty them.
We have introduced a possible organizational and technological framework for the integrated management of urban freight transportation and have identified a number of important associated planning and operation issues and the corresponding Operations Research models. We have also described a formulation for one of these problems, the design of the proposed logistical structure. The proof-of-concept experimentation, based on data from the city of Rome, is very encouraging. It indicates that such a system may indeed contribute towards reaching the goals of a better city environment at a reasonable cost.
Many stages have to be accomplished, however, before such a system is fully deployed. There are methodological challenges, of course, in developing the appropriate models and tools for the analysis, planning, and operation of the system. More formidable still are, probably, the social and political challenges. We have initiated work on the former. We hope the current dialog between all stake-holders will develop and become more general. We cannot presume what form integrated freight city logistics will take. But it will include some form of consolidation and control. These are issues the models and methods we develop will help address.
