Assessing the Ecological Footprint of an Urban Transportation System
2003
The ecological footprint methodology is here applied to the urban transport system of the Italian town of Palermo (Sicily). By only using the current running fleet, a synthetic indicator represented by the "equivalent bio-productive" land, corresponding to the actual transport configuration, will be built up. This indicator can be usefully adopted for ranking various options in the urban context referring, for example, to different arrangements of the transportation demand between private and public means. This could allow local administrations to environmentally hierarchizing alternative plans concerning the urban transportation
Indicators for sustainable mobility in the cities
2011
The creation of a sustainable transport system is the main objective of European transport policy. This system should encourage facilities to connect all people and should be linked with economic, social and environmental aspects of society. Current trends and future challenges will meet a growing "accessibility" demand, highlighting concerns about the sustainability of transport. Therefore one of the priorities of transport policy is the improving of overall quality of transport, including aspects related to: personal safety, accidents and health hazards reduction, protection of passengers rights and of accessibility to remote areas. This paper is dedicated to sustainable development, with…
City logistics – A Strategic Element of Sustainable Urban Development
2016
Abstract The main purpose of this article is to present the basic development trends in the logistics area of the city, some concept of sustainable logistics and innovative technologies prerequisites to its implementation. The author shows such intelligent technologies as e.g. intelligent traffic control, modular containers, which help to improve utilization of vehicle capacity, and alternative means of transport. This will help to reduce the load on the road infrastructure, thus improving the quality of the environment and life in the city. The main trend in sustainable city logistics is cooperation between suppliers, customers and the public administration. Implementation of intelligent l…
Impact of COVID-19 pandemic on mobility in ten countries and associated perceived risk for all transport modes.
2021
The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for all transport modes (walk, bicycle, motorcycle, car driven alone, car driven in company, bus, subway, tram, train, airplane) before and during the restrictions adopted in ten countries on six continents: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. This cross-country study also aims at understanding the predictors of protective behaviors related to the transport sector and COVID-19. Findings hinge upon an online survey con…
URBAN TRANSPORTATION GOVERNANCE AND WICKED PROBLEMS: A SYSTEMIC AND PERFORMANCE ORIENTED APPROACH
At an urban level, among the services that the public sector is called upon to provide, transportation plays a central role (Meyer & Miller, 2000). Urban mobility systems are complex. This complexity – characterized by pluralism, institutional fragmentation and uncertainty – determines what literature defines as ‘wicked’ problems (Rittel & Webber, 1973); namely issues that are hard to define and manage, and often lead to counterintuitive behaviours when actions are taken to resolve them. In the last 40 years, Public Administrations around the world experienced various reform processes. These processes - that were aimed at overcoming the limitations of the institutional settings already in p…

Solving congestion in cities : policies and contradictions
2009
International audience; Most cities in the world are now facing traffic gridlock. Local governements and transportation authorities are trying to tame a phenomenon which takes in fact very different forms depending on the level of social and economic development. Is it really possible to compare freeway gridlock in Los Angeles with rickshaw gridlock in Dhaka, Bangladesh ? When French cities embrace the development of urban bicycling, Chinese cities limit the use of bicycles. Using cases of cities in different parts of world, this presentation willl try to find some common trends in urban mobility policies and examine some contradictory developments.

Les défis de la gouvernance urbaine à Manille
2014
La région capitale des Philippines est une des plus grandes aires urbaines du monde en termes de population. Le périmètre officiel du Grand Manille (17 municipalités) abrite environ 12 millions d’habitants et l’expansion périmétropolitaine porte le chiffre réel de Manille à 15 ou 16 millions d’habitants.La rapide croissance de l’aire urbaine depuis les années 1960 a conduit à de gros problèmes de gestion du logement, de la circulation, des déchets et des risques d’inondation, entre autres. Les phénomènes sont interdépendants.Créée sous Ferdinand Marcos, la National Capital Region fut gérée par son épouse Imelda Marcos, gouverneure du Grand Manille. Après la chute de la dictature, une volont…
