Abstract

The City of Edinburgh in Scotland in the UK had advanced plans for a congestion charging scheme until 25 February 2005. However, these plans were abandoned at that time after a referendum that resulted in a ‘no vote’. This paper explains the origins of the scheme, outlines its nature, extent, charging technology and predicted effect; it also analyses the difficulties that exist when attempting to plan and implement such a scheme in a particular governance context, and when there is little unanimity of public opinion about the need for a scheme.

As well as the primary documentation from the proposals (e.g. public inquiry submissions, papers to government), the paper also draws upon a series of face-to-face interviews that were undertaken with key stakeholders. It also provides an analysis of press coverage in the local (Edinburgh) and national (Scottish) newspapers in the run-up to the referendum. These sources explain both the systemic and more local barriers to the scheme's implementation.

The paper draws key lessons which are important for authorities considering the implementation of a road user charging scheme, by suggesting how legislative and governance barriers to implementation can be reduced. The lessons are of relevance world wide.  相似文献

In Britain, capacity charges are levied on train operators to cover the costs imposed by increased reactionary delays – i.e. the delay that an already late train causes to a following train. These charges are based on the link between capacity utilisation and the level of reactionary delay. An established method for measuring capacity utilisation was adopted called The Capacity Utilisation Index (CUI). In this paper, we propose an alternative methodology based on the theory that the level of reactionary delay will be determined by the minimum gaps that exist between trains. We test this measure with a new data-set for the East Coast Main Line and show that it performs better than CUI. Finally, we comment on the implications of this finding for charging and for the construction of timetables.  相似文献

There has long been conflict over the degree to which railways should follow commercial or social investment criteria. This paper outlines the components of a comprehensive social cost‐benefit analysis of railway investment, and then describes the current approach in Britain. British Rail investment proposals are subject to a purely financial appraisal, although in the subsidized sectors of the railway this is subject to the proviso that a ‘broadly comparable’ level of service should be maintained. Local authorities and private operators are able to apply for a central government grant towards the cost of schemes they sponsor. But grant is only payable in respect of external benefits—that is, benefits other than to public transport users. Sponsors are also expected to seek contributions from private developers wherever possible. The difficulties to which this approach leads are discussed, and illustrated with two case studies of actual schemes. In one, it appears that failing to consider disbenefits to bus operators (and in turn to users of bus services) could lead to investments being undertaken which are not justified. In the other, a scheme which yields a high Net Present Value could not go ahead, in the form that we evaluated, because there is no way of recouping enough of the user benefits as revenue. Both are examples of the sort of distorting effect on decision‐making the current regime may have.  相似文献

In the pursuit of sustainable mobility policy makers are giving more attention to cycling. The potential of cycling is shown in countries like the Netherlands, where cycling covers 25 % of all person trips. However, the effect of policy interventions on cycling demand is difficult to measure, not least caused by difficulties to control for changing context variables like weather conditions. According to several authors weather has a strong influence on cycling demand, but quantitative studies about the relationship are scarce. We therefore further explored this relationship, with the aim of contributing to the development of a generic demand model with which trend and coincidence in bicycle flows might be unraveled. The study is based on time-series between 1987 and 2003 of daily bicycle flows, collected on 16 cycle paths near two cities in the Netherlands. The regression analyses show that, not surprisingly, recreational demand is much more sensitive to weather than utilitarian demand. Most daily fluctuations (80 %) are described by weather conditions, and no less than 70 % of the remaining variation is locally constrained. The regression can therefore mainly be improved by incorporating path specific, as yet unknown, variables. We used the regression results to calculate weather-inclusive bicycle flow predictions and found indications of a downward trend in recreational demand. This trend has been off-set in the observed flows by more favorable weather conditions over the years considered.  相似文献

One of the biggest unresolved problems regarding the completion of the free internal transport market within the European community is the problem of harmonization of taxation on the road haulage industry. As the highest tax country, Britain might be expected to have to reduce its level of taxes as part of any harmonization.

This paper considers the current methodology of the British Department of Transport regarding the allocation of the track and external costs of road transport, in the light of developments in methodology and experience elsewhere in Western Europe and North America. We find a number of reasons for believing that, far from overstating the marginal social cost of use of roads by the road haulage industry, the current British approach actually understates it. Thus any move towards harmonizing tax levels may reduce taxes in Britain at a time when they should be increasing.  相似文献

In our critique for the Buses White Paper, we argued that ‘competition for licences’ could achieve most of the benefits of competition without the major disadvantages of ‘competition on the road’. In response to the comments of Beesley and Glaister, we explain how comprehensive franchising of good and bad routes alike would encourage effective competition, whilst providing conditions for the transparent continuation of cross‐subsidy where that was the choice of the local authority in question. We correct their misrepresentation of our arguments on the desirability of cross‐subsidy and on the case for minibuses, and explain why we believe that such cost savings as are achieved will be mainly at the expense of staff or customer service. Finally, we restate the case for believing that a unified planned timetable will provide a better service for a given level of resources than will uncoordinated competitive services.  相似文献

This paper compares the major role played by suburban rail (S‐Bahn) systems in West German cities with the much more limited role of rail in the British conurbations. Clearly, the difference owes much to the institutional and financial arrangements in the two countries. In West Germany, large amounts of earmarked funds have been available for rail investment, whilst the Federal government has been willing to shoulder much of the burden of operating subsidies. The Verkehrsverbund has emerged as a highly effective way of coordinating fares and services without direct ownership of any mode of transport. By contrast in Britain funds for rail investment have been much more limited. Progress with integration has been far slower, and is threatened by current government policies regarding both bus deregulation and the abolition of the Metropolitan county councils. Whilst rail is firmly established in German cities, its future in Britain looks bleak.  相似文献

Whilst the emphasis of European Union rail legislation to date has been on freight, measures such as separation of infrastructure from operations, infrastructure charging regimes and regulation have major implications for the passenger sector. But implementation of these measures in many countries has been inadequate. Crucial to overcoming these problems is the establishment of strong independent regulators in all member states. There is currently no requirement for competition in the passenger sector except for international services, but there is experience both of open access for commercial services and of competitive franchising. However, even where permitted open access competition has been very limited and there is evidence that undesirable cream skimming may be a problem. Experience of franchising has generally been positive, but in some cases it has failed to drive down costs. It is concluded that a combination of more sensible risk sharing, a determination not to renegotiate, longer franchises and limited open access competition where justified by benefits is likely to be the best way forward.  相似文献
