This paper focuses on sustainable mobility city planning as a process that innovates and develops cities.The indications laid down by the European Union (UE) urge us to review urban spaces in order to transform degraded areas into smart areas and, therefore, restart a process of rebalancing and sustainability, with the goal of transforming cities into smart cities. The planning activity supports the social, economic, and technological change processes. The regeneration of disused areas creates opportunities for sustainable growth. This paper presents the issue of urban regeneration. A project of an urban distribution center, in a city logistics system, is designed for a disused railway area, located near the harbour in Reggio Calabria. The case study has tested the application of a model of urban regeneration, through the design of innovation zones, according to European Union strategies to encourage the development of a smart city.
The paper deals with methodologies to support an ex-ante assessment of the impacts generated by the introduction of city logistics measures on last-mile freight distribution services. Some models and algorithms are applied and compared to solve the vehicle routing problem for freight deliveries in the town of Reggio Calabria with the introduction of an urban distribution centre and of green freight vehicles. Heuristic routing algorithms are compared in terms of sequence of clients (retailers) visited subject to some constraints given by the presence of UDC and the limited autonomy and capacity of freight vehicles.
As is well known, city terminals in densely populated areas affect traffic, infrastructures, health and the environment. In more detail, a new terminal has the potential for influencing urban transport strategies, environmental aspects, infrastructure development, city logistics, freight transport, port and city interaction, and life cycle management. In light of the above facts, the objectives of this study were confined into the preliminary analysis of the life cycle cost (LCCA) associated to several hypotheses in terms of geometric design and pavement design of a new city terminal. Hypotheses included: a) the choice of the location of the freight terminal (close to railway track, motorway and port of a town having a population of about two hundred thousand people); b) layout and main heavy vehicle paths from/to the terminal; c) equipment; d) main operations; e) dynamic and static loads of equipment; f) pavement design alternatives, construction and quality assurance. Under the above hypotheses, a life cycle cost analysis has been carried out, including rehabilitation alternatives, resurfacing alternatives, analysis period, salvage value, interest and inflation assumptions, present value derivation. Based on the results obtained, rehabilitation options emerged as a key factor in the minimization of the overall life cycle cost in terms of present values. Results can benefit both researchers and practitioners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
