If you go to the newly revised <a href="http://www.wtransport.org/">www.wtransport.org</a> website, you will be able to have a look at and download this number of the Journal.  Just below you have the Contents and short Abstracts of the articles.   In the months ahead we shall be working to make WTPP more interactive and to support other initiatives that are in tune with our own ideas and principles. This will only work if our readers join in and we hope that this will happen.   Note: Might you kindly do this for us?

Given rising concerns over fossil fuel consumption and CO2 production by passenger cars, the automotive industry and governments are evaluating strategies for sustainable mobility. The European Communities (2001) believes that there is great promise in the development of a new generation of hybrid electric cars (electric motor coupled with an internal combustion engine), cars fuelled by compressed natural gas and, in the longer term, cars powered by hydrogen fuel cells. The paper’s objective is to describe the specific competitive conditions that will determine the successful market diffusion of natural gas vehicles in Switzerland. Natural gas vehicles may smooth the impact of transport as they are less polluting and may be run on biogas, a renewable fuel.   Keywords: Emissions, natural gas vehicles, fuel cells, Switzerland, competition analysis   Are highways best run by concessions? The Italian experience Giorgio Ragazzi   Highways in Italy were built on a “cost of service” principle, but in 1999 the regulatory system was changed into a “price cap”. The new system has failed in its purpose to relate tariffs to productivity or quality improvements, while it has allowed a dramatic increase in concessionaires’ profits. The State obtained a large profit from the privatization of Autostrade, by extending its concession for 20 more years.  Financing highways through project backing has numerous drawbacks, mainly fragmentation and irrational pricing. Regulation is difficult and inevitably discretional, with a high risk of “capture” of the regulator. Benefits from competition could be better obtained through unbundling.   Keywords: Project Financing; Motorways; Regulatory Policies   The effectiveness of policies to address urban environmental problems: some perceptions and realities Dominic Stead   The growth in transport volume is adding to urban environmental problems and is one of the main reasons for serious concerns about urban environmental quality. A wide variety of policies is available to tackle urban environmental problems associated with transport. This paper examines the effectiveness of various types of policies that are available, looking at public perceptions of effectiveness, empirical measures of effectiveness and the actual implementation of measures. The paper also examines concerns about the urban environment and the relationship between these concerns and perceptions about the effectiveness of measures to tackle environmental problems associated with transport. The paper synthesises information and data from a number of sources and re-analyses data from large-scale European public opinion surveys. Keywords: Perceptions, policy effectiveness, transport, urban environment, public opinion, Eurobarometer, Europe.       </div> </body> </html>
