    Get PDF
    This paper reports on a desk study carried out by the Institute for Transport Studies as part of a wider study of opportunities for inter-regional working in the trans-Pennine corridor, considering economic, environmental and transport issues. It draws together available information on transport and movement flows in the trans-Pennine corridor. These patterns of movement are examined from a broad perspective which considers intra-regional, inter- regional and international movements within and across the study area. The report proposes a regional package approach to transport, based on demand management and modal transfer

    Are City Logistics Solutions Sustainable? The Cityporto case

    Get PDF
    Urban logistics is a field that studies the best solutions for urban freight distribution with high environmental objectives. However, most actions are started by public authorities without taking into account the impacts of the new organizational schemas in the existing distribution enterprises' organization. This paper sets out to show that urban logistics approaches are currently important with reference to the noise and pollution in city center. To this end, we present the success experience of Cityporto (Padoua) in Italy. Cityporto is a service which makes deliveries in city centre by using GPL and electric lorries. So, the service is considered as less polluting as a conventional approach. In this context, it allows a delivery at any time of the day, also in the Limited Traffic Zone which is closed at certain hours of the day. This is based on the findings from an exploratory qualitative approach. Documentary analysis several interviews have be made. These concern three internal stakeholders of Interporto di Padova (the company which manages the intermodal platform of Padova, in charge of Cityporto) and one member of Padova's Municipality (which promote the project). The results of this case study show that environmental aspect is one of the foundations of the project, but the economic continuity has to be first ensured. Indeed, the preservation of this service on the long term is subjected to its solvency. Moreover, its success is associated to the recognition by employees, and also customers. With regard to the collected information, it is possible to propose a balanced scorecard, where three axes emerged in connexion with economic, environmental and social dimensions. The paper makes a contribution to the evaluation and measurement of city urban logistics using a success story that has been developed from the practitioner perspective. This experience could provide a basis for further practices in Italy and other European countries. In conclusion, the proposed case study is presented for its academic, policy and managerial implications. This experience conceptualises city logistics in relation with the Sustainable Development, setting the main objectives and steps of urban planning for freight distribution and logistics issues. But above all, it provides an understanding of the key success factors in a green transport organisation which can become a pivotal position in the upstream supply chain. De facto, the study should facilitate the implementation of green urban logistics taking into account the importance of the project's economic continuity.City logistics, sustainability, case study, qualitative research, management

    Promoting Intermodal Connectivity at California’s High Speed Rail Stations

    High-speed rail (HSR) has emerged as one of the most revolutionary and transformative transportation technologies, having a profound impact on urban-regional accessibility and inter-city travel across Europe, Japan, and more recently China and other Asian countries. One of HSR’s biggest advantages over air travel is that it offers passengers a one-seat ride into the center of major cities, eliminating time-consuming airport transfers and wait times, and providing ample opportunities for intermodal transfers at these locales. Thus, HSR passengers are typically able to arrive at stations that are only a short walk away from central business districts and major tourist attractions, without experiencing any of the stress that car drivers often experience in negotiating such highly congested environments. Such an approach requires a high level of coordination and planning of the infrastructural and spatial aspects of the HSR service, and a high degree of intermodal connectivity. But what key elements can help the US high-speed rail system blend successfully with other existing rail and transit services? That question is critically important now that high-speed rail is under construction in California. The study seeks to understand the requirements for high levels of connectivity and spatial and operational integration of HSR stations and offer recommendations for seamless, and convenient integrated service in California intercity rail/HSR stations. The study draws data from a review of the literature on the connectivity, intermodality, and spatial and operational integration of transit systems; a survey of 26 high-speed rail experts from six different European countries; and an in-depth look of the German and Spanish HSR systems and some of their stations, which are deemed as exemplary models of station connectivity. The study offers recommendations on how to enhance both the spatial and the operational connectivity of high-speed rail systems giving emphasis on four spatial zones: the station, the station neighborhood, the municipality at large, and the region

    Local sustainable mobility management. Are Portuguese municipalities aware?

    Get PDF
    Urban mobility has become an international problem and several countries have joined together in different consortia, signing international agreements and developing projects with a view to establishing new standards for current mobility levels and the development of the transport systems of the future. Although such worldwide increasing effort regarding sustainable mobility issue, namely by the most proactive European cities, it is not yet clear why measures towards sustainable mobility are not implemented by the generality of local authorities. The main goal of this paper is to identify the different sustainable mobility strategies and the corresponding perceptions by local public authorities. Such local governance aspects have yet to be dealt with appropriately and in a credible way. This shortcoming is particularly acute in Portugal where sustainable urban mobility management is still highly underdeveloped and very few studies have been dedicated to the matter. We provide new evidence on the perceptions and strategies of the Portuguese local public authorities regarding sustainable urban mobility management. Through a survey to all Portuguese municipalities we provide brand new evidence on their perceptions and strategies regarding sustainable urban mobility management. Estimates based on econometric regressions indicate that the most mobility-conscious municipalities are, on average, those that are richer, more cultural and educated, possess alternative transport parks and routes, have larger and more human capital intensive mobility departments. Results show that more than simply participating in urban regeneration programs it is necessary a more committed attitude, namely that municipalities’ urban plans explicitly mention mobility issues and indicators. All the models estimated clearly evidence a higher awareness of North municipalities towards sustainable mobility issues.Zona Euro; Sustainability; mobility management; regions; human capital

Copyright @ 2009 Elsevier B.V.This study discusses a decision support framework that guides policy makers in their strategic transportation related decisions by using multi-methodology. For this purpose, a methodology for analyzing the effects of transportation policies on environment, society, economy, and energy is proposed. In the proposed methodology, a three-stage problem structuring model is developed. Initially, experts’ opinions are structured by using a cognitive map to determine the relationships between transportation and environmental concepts. Then a structural equation model (SEM) is constructed, based on the cognitive map, to quantify the relations among external transportation and environmental factors. Finally the results of the SEM model are used to evaluate the consequences of possible policies via scenario analysis. In this paper a pilot study that covers only one module of the whole framework, namely transportation–environment interaction module, is conducted to present the applicability and usefulness of the methodology. This pilot study also reveals the impacts of transportation policies on the environment. To achieve a sustainable transportation system, the extent of the relationships between transportation and the environment must be considered. The World Development Indicators developed by the World Bank are used for this purpose

    Urban Goods Movement and Local Climate Action Plans: Assessing Strategies to Reduce Greenhouse Gas Emissions from Urban Freight Transportation

    Get PDF
    This report examines how freight transport/goods movement has been addressed in U.S. city climate action planning. Transportation generally is a major contributor of greenhouse gas (GHG) emissions, and freight transport represents a growing component of transportation’s share. Almost all climate action plans (CAPs) address transportation generally, but we wished to focus on efforts to reduce GHG emissions from freight transport specifically. We analyzed 27 advanced local CAPs to determine the degree to which freight transport was targeted in goals and strategies to reduce GHG emissions. We found only six CAPs that included direct measures or programs to reduce freight emissions. Many of the CAPs mentioned general transportation objectives such as lowering vehicle miles traveled or reducing emissions from city-owned vehicle fleets, but most did not include strategies or actions that explicitly targeted freight transport. We identified the specific strategies and actions that cities are taking to address GHG emissions from freight transport, such as working with the freight community to promote anti-idling and encourage transitions to electric and alternative fuel delivery vehicles. We also analyzed freight transport plans relevant for the same cities, and found that most do not explicitly mention reducing GHG emissions. Most of the freight plans are focused on improving reliability and efficiency of freight movement, which would likely have the ancillary benefit of reducing GHG emissions, but that goal was not explicitly targeted in most of these plans. Based on our findings, we recommend that cities specifically target freight transport goals and strategies in their CAPs and better coordinate with planners developing freight transport plans to identify GHG emission reduction approaches

    Sustainable supply chain management in city logistics solutions: an experience's comeback from Cityporto Padua (Italy)

    Get PDF
    The sustainable logistics and transportation studies constitute a primordial research axis in the enterprises' governance. In the last years, many reflections and developments in logistics research have studied the economic and the environmental questions related to supply chain management, but only few of them consider sustainability in its totality. Moreover, in practice, city logistics systems conception and planning is currently following a sustainable approach. The aim of this paper is to start a reflection about the three dimensions of sustainable supply chain management (economic, environmental and social), and illustrate these concepts by the results of an experience's comeback from a city logistics system, Cityporto (Padua, Italy).Sustainable Supply Chain Management; experience's comeback; urban freight distribution
