Women,travel and the idea of 'sustainable transport'

Women form an increasingly large proportion of both the populations of the US and of European countries. This, together with the changing role of women in modern society, has important potential implications for transport policy. Looked at from the micro level, women have different travel patterns from men, reflecting factors such as lower labour force participation, lower income levels, their traditional role in the family, the decision-making structure within households, the current age distribution and physical vulnerability. The situation is changing and this will have implications on transport demands. The female population is also, on average, getting older. Traditional travel modelling spends much time on modal attributes, such as speed and cost, but for many women this may not be the central issue. Security is often important. Standard traffic models only implicitly allow for gender (e.g. travel time is valued different from work and non-work trips). With the increased complexity of life styles and the growth in multi-purpose trips by women, the conventional approach to travel time valuation may need to be rethought. This paper looks at some of the emerging issues regarding women and travel and puts them in the context of the emerging ideas concerning sustainable transport.     

Public–private partnerships: a review of economic considerations with particular reference to transportation projects

The paper sets in context some of the more recent work that has been conducted on public–private partnerships (PPPs) in the provision and operation of infrastructure. PPPs essentially involve a government or its agent signing an agreement with a private company or consortium to supply it with services with the private sector actor involved in major elements of designing, building, temporarily ‘owning’, and running the physical assets; basically they are long-term development and service contracts between government and a private partner. The paper outlines the development of economic thinking regarding the rationale behind PPPs, the extent to which unbundling is optimal and the forms that it may take, the nature of the contracts that are enacted and their renegotiation, the awarding of contracts, and matters of possible corruption. By way of focus, it also provides some indication of what empirical studies in the transportation have thrown up regarding the outcomes of PPPs.     

Shipping economics: where we are and looking ahead from an institutional economics perspective [1]

There have been significant changes in the nature of shipping services in recent years. These have been most notably in the liner segment, but other parts of the market have not remained static. Technology shifts have been responsible for some of the change, but there have also been developments in institutional structures and managerial approaches. The economic drivers behind the sector, however, remain relatively poorly understood, despite a copious literature on shipping. Managerial economics has tended to put emphasis on the emergence of more sophisticated logistics structures and the role of information to tighten the overall supply chain. Industrial economists have been concerned with technical change and in particular with its interaction with more liberal markets structures. Often tied with this has been interest in the underlying nature of shipping markets (e.g. competitive, monopolistic or contestable) and, depending on the outcome, whether there is price leadership, collusion, predatory behaviour or whatever. Much of this work has been aspatial, treating shipping as any other industry with distance between demand and supply ignored or incorporated in a very simplistic manner. Environmental economists have focused on matters of fuel efficiency and pollution. This paper takes a broad overview of shipping economics in the context of the larger institutional framework within which it operates. It seeks broader analysis within an institutional economics framework, but also highlights some of the problems of achieving this.     

Benefit transfers: are they a satisfactory input to benefit cost analysis? An airport noise nuisance case study

Benefit cost analysis in a variety of guises has established itself as a useful tool in public policy-making. It is an approach widely adopted in appraising a wide range of infrastructure investments and has been regularly used in legal proceedings. In the context of this study, it forms a common procedure for assisting in the assessment of the social benefits and costs of airport investment. It is not, however, a technique without its limitations. Beside a range of technical concerns, conducting a comprehensive benefit cost analysis can be resource-intensive and time-consuming. Recently, there have been efforts to make its application more efficient by adopting benefit transfer procedures. This involves making use of findings from one study as inputs into other policy-making activities. While applying secondary data to a new policy issue has a long pedigree, new areas of application involve taking non-market valuations of externalities from one study and transferring them to a different policy site. This paper looks at some of the limitations of employing benefit transfers and uses noise nuisance aspect of airport investment policy appraisal as an illustrative case. Based upon a meta-regression assessment of hedonic price models, the findings suggest that caution should be exercised in conduction benefit transfers.     

A transit ridership‐revenue model

The paper outlines the theoretical underpinnings of an urban mass transit revenue and ridership model designed to provide medium term forecasts of future trends in situations of data sparsity. The specific example laid out in the paper relates to the Greater Vancouver Regional District but the framework is of general applicability. Much of the informational input at the initial stage is of a general kind and details of the specific transit system and local area are of the sort which should be readily available to most urban authorities. The model developed is designed for use on a desk‐top micro‐computer and offers an inter‐active method of forecasting. The operator has the facility to both consider fare policy sensitivity and review alternative scenarios about future trends in exogenous factors. A selection of forecasts developed for the GVRD is provided to reveal the main features of the approach.     

Transport deregulation and cross‐border trucking in North America

Internationally, recent years have seen a spread of deregulatory policies with respect to transport. Equally, transport movements across national boundaries have expanded as trade has grown. Despite these two quite noticeable trends comparatively little has been written on the problems that are created for cross‐border traffic as the result of differential changes in national regulatory policies. This paper is concerned with looking specifically at what has happened in the context of road freight transport movements across the U.S.‐Canadian border and the wider (especially for the formulation of a Common Transport Policy for the EEC) lessons which can be learned from it.
