The taxi's role in urban America: Today and tomorrow

Changes in the economic and demographic characteristics of US cities over the past two decades have modified but have not diminished the need for extensive public transportation service in these areas. The vast bulk of trips to work, to shop, and for most other purposes within large American cities are still made by residents of those cities, a significant portion of whom do not own or have access to an automobile. Expensive and far-ranging programs to enhance surburban commutation to the central city by means of rail rapid transit do little to meet the needs of those who still must rely upon local, extensive service within the city.One form of public transport — the taxicab — offers the quality and flexibility of service which even those of limited means find well worth the price. As a consequence, fleet taxicabs serve almost 40 percent more passengers than all US rapid transit systems and about 60 percent as many passengers as all bus transit systems. Removal of archaic and restrictive regulations governing the number and use of taxicabs in major US cities would promote more effective and widespread use of this, the only form of public transit that still operates — at a profit — without public subsidy.     

Benefit-cost analysis for labor intensive transportation systems

Labor-intensive systems such as bikeways and pedestrian ways suffer in transportation planning in part because traditional benefit-cost analysis focuses on narrow, private transportation savings (e.g., reducing vehicle and time costs).Planners need benefit-cost frameworks which capture the community-wide effects of such innovative transportation systems — reduction in air pollution, less congestion, and increases in exercise and outdoor recreation. This study discusses practical methods for planners to include such categories in their analyses and applies these methods to two case studies. The analysis yields benefit-cost ratios which are much higher than those found in most public projects — suggesting negative returns to marginal automobiles in congested areas such as university campuses. The paper concludes with some suggested bikeway planning guidelines that emerge from expanded benefit-cost analysis.     

Parking policies in large cities in Germany

This article deals with highly motorized large West German cities of about 200,000 inhabitants and more, which usually provide reasonable public transport systems. Illegal parking with shares of about 40 to 50% of the total parking is widespread in the parking problem areas of those cities, especially in the inner-city residential and mixed-use areas. Parking spaces are demanded by residents, employees, customers and visitors, and by delivery and service traffic. The different characteristics of parking demands by different user groups are discussed. The total parking supply consists of public and private spaces. The share of private spaces is about 40 to 50% of the total parking spaces in German cities. The amount of car traffic generated by a parking space depends on parking duration and parking turnover, as well as on search traffic. So the change of a space from long-duration use of an employee to short-duration of customers — as often discussed in parking concepts — generates at least five-fold car traffic. The measurements and effects of parking control of public spaces as well as the parking regulations in zoning ordinances, restrictions on the construction of new private parking spaces and park-and-ride are discussed. Finally, a parking concept methodology — using the example of Frankfurt am Main — is discussed.     

Transport in Tokyo

This paper gives a review of the historical and geographical preconditions as well as of the population and economic development which led to the unique and complex transport systems of Tokyo. Tokyo Metropolis, one of the most populous cities in the world, is located in the National Capital Region of Japan where 32 million people are living today. The special transport problems deriving from this high population density are described in context with the development of employment, transport infrastructure and motorization. Due consideration is given to the influence exerted by the structure of the whole region on the overall traffic behaviour.

Several transport phenomena and problem solutions which are typical of the traffic systems in Tokyo are described, such as the change of rush hour congestion rates depending on subway extension, modal split for different trip purposes in the inner urban area, or information via local radio broadcasts with very short range of transmission.

The main current transport issues are discussed. Though the transport networks in Tokyo are some of the most developed in the world, there is still heavy congestion in rush hours. The basic policy therefore is the further strengthening and improvement of the public transport network.     

Critical success conditions of collaborative methods: a comparative evaluation of transport planning projects

This paper explores critical success conditions of collaborative planning projects in the area of urban transport, evaluating the impact of new collaborative methods, instruments and processes on project performance. Hypothesis building is based on a comparative, empirical research design, rather than on deductive theory construction. Potential critical success conditions are derived from literature. Based on five urban transport planning projects in Gothenburg (Sweden), London (United Kingdom), Milwaukee (United States), Tokyo (Japan) and Mexico City (Mexico), a rough set analysis of the five cases reveals validated success conditions, which can be used for formulating hypotheses for further research or for policy and process improvement. The results suggest that a dedicated management of the multi-actor network, a high diversity of actors, as well as an extensive use of knowledge integration methods in combination with a high network density are critical success conditions of these planning processes. Surprisingly, the extensive use of unilateral methods also showed to be an important success condition. The traditional role of the planner will have to be complemented with the expertise of network and methodology management. The authors conclude that rough set analysis can be a valuable addition to narrative, single-case analysis of collaborative urban transport planning processes.     

Urban transport policy development: two case studies in the Middle East

Abstract

The recent completion of two major transport studies of predominantly urban areas in the Middle East (Amman‐Jordan and Bahrain) has provided the opportunity to compare and contrast the transport characteristics of, and medium term transport policies for, the two areas.

While in structure the two transport systems have many similarities, their base year usage differs significantly. In view of the much lower income levels in Amman, and the resulting lower levels of car ownership, greater reliance is placed on public transport in Amman than in the more car‐oriented society in Bahrain. Against this background, and in the context of broadly similar overall levels of growth in travel demand, their development in the medium term future should follow different paths. Amman will need to depend on public transport very heavily, with only limited road building. Bahrain should be able to develop a satisfactory road system, with public transport playing its current role except for the provision of services for some relatively modest number of restrained private vehicle users. In both cases, however, substantial investment in off‐street parking spaces is needed.

The paper briefly describes the social and economic backgrounds of the two areas, and reviews the transport systems and the organisations responsible for them. Travel demand forecasts are summarized, leading to the transport plan and policy development. The prospects for implementation are discussed, and the paper lastly focuses on some aspects which are key to the development of the transport systems in the two countries.     

‘Unconventional modes’ of transport in the United Kingdom—A review of types and the policy context

‘Unconventional modes’ (UCMs) of public transport have been emerging steadily and unobtrusively in the United Kingdom over the last two decades, largely originating in rural areas. Since 1977, there has been a quickening expansion of numbers and diversification of types in the light of governments' increasing concern with the cost of supporting ‘conventional’ public transport and the search for cheaper alternatives. An essential part of this review is to establish a definition of ‘unconventional’ as an aid to classifying the wide and increasing diversity of modes, and clarifying terminology. UCMs overlap with ‘community transport,’ which caters for the mobility needs of elderly and handicapped persons. In the context of bus service deregulation in 1985/6, the UCM sector is expected to expand although its precise future role is unclear.     

The formulation of marketing strategy in urban public transport

This paper prescribes the parameters of marketing strategy formulation in the context of urban public transport and emphasises in particular the usefulness of the marketing mix and segmentation concepts. A marketing mix comprising the two primary dimensions of service attributes and promotion is advocated, the service attributes to include price, in-vehicle time, mesh density, frequency, reliability and comfort. Three primary trip purpose segments are identified viz. journey-to-work, shopping, and leisure/social trip segments, but these may be expanded into a twenty-four cell matrix once origin-destination and car access factors are included. The sensitivity of demand in these segments is examined mostly by reference to demonstration and experimental project data drawn from the United States and the United Kingdom. For the three primary trip purpose segments demand elasticity is shown to be greater for non-price than for price features; for both price and non-price service features elasticity is shown to be a function of journey purpose being least elastic for journey-to-work trips and most elastic for social/leisure trips. The role of promotion is examined and its importance to the successful marketing of public transport clearly demonstrated.This paper is a condensation of material appearing in The Management of Urban Public Transport: a marketing approach, by P. J. Hovell, W. H. Jones, and A. J. Moran, to be published by Saxon House and Lexington Books in 1975.     

Modeling access to public transport in urban areas

It is important to measure public transport accessibility to help improve the sustainability of transport systems in metropolitan areas. Although many studies have defined different approaches for measuring public transport accessibility, there have been limited methods developed for measuring accessibility levels that incorporate spatial aspects. Population density is an important distributional indicator that has also been ignored in previous methods developed for quantifying accessibility. This paper outlines the research context for measurement of public transport accessibility and then describes a methodology developed as well as an application the Public Transport Accessibility Index in Melbourne area, Australia. Using the Victorian Integrated Survey of Travel and Activity dataset, we applied separate‐ordered logit regression models to examine how the new index performs with a series of predictor variables compared with two existing approaches. Key findings indicate that there is a higher probability of public transport patronage in areas with higher levels of accessibility. Furthermore, it was found using statistical modelling that the new index produces better results compared with previous approaches. Copyright © 2016 John Wiley & Sons, Ltd.     

European freight transport and the environment: empirical applications and scenarios

Environmental issues have received a prominent place in transport policies of most European countries. The coordination of such policies however, is fraught with many difficulties. The increasing freight flows after the European integration are a source of concern, but have not yet led to straightforward and effective environmental strategies.The paper focuses on the Trans Alpine freight transport systems in the light of the future integration of single national transport systems into the European transport network. The environmental, social and institutional peculiarities of this ‘region’ have favoured—in the past—the development of strong nationally-oriented policies, partly in contrast with the goals promoted by the European Union. The present analysis aims to highlight opportunities, and limits inherent, in the implementation of various infrastructure projects oriented towards a drastic change of the Alpine transport systems structure. The Alpine countries, viz. Austria and Switzerland, play a central role in the promotion of environmental benign modes of transport of goods, with a clear focus on rail. The route choice and modal split of freight flows in Europe are taking place simultaneously. In this paper the results of European freight flow models (based on logit analysis and neural networks) will be presented. An important exercise is then to assess the consequences of various types of eco-taxes on road transport in Europe. In this context, several policy scenarios will be dealt with.     

Energy use in passenger transport in OECD countries: Changes since 1970

This paper analyzes some of the changes that took place in the structure of energy use for passenger travel in industrialized countries. Data is presented on energy use and travel activity for the four major modes of travel — automobile, bus, rail and air — for eight OECD countries: the United States, Japan, the United Kingdom, West Germany, France, Italy, Sweden, and Norway. We use the Laspeyres and Divisia indices to analyze the causes of the change in energy use between 1970 and 1987. The total change in energy use for travel is explained by changes in domestic passenger transport volumes, the mix of modes of travel, and the energy intensities of each mode. We have found two important effects that have a fundamental impact on energy use for travel since 1970. First, shifts among modes of transport towards more energy-intensive ones and large increases in volumes of travel (measured in passenger-kilometers) increased energy use for travel in many OECD countries, often more rapidly than the overall growth in GDP. Second, energy intensities, measured in mJ/passenger-kilometer, of passenger transport fell only in a few countries between 1970 and 1987. Even though individual automobiles have become more energy-efficient, greater size, power, and weight, worsening traffic conditions in Japan and Europe, and fewer people in cars restrained or even offset efficiency improvements. Particularly notable are the increases in intensities in Japan and Germany. The most important exception to this trend was the United States, but the intensities of land-based travel remain higher there than in most other countries. These findings lead to a pessimistic outlook for future energy use for travel. After all, if little or no energy was saved during the decades of high fuel prices, what can be expected in the 1990s?     

Traffic safety,usability and streetscape effects of new design principles for major urban roads

An important aspect of area-wide traffic calming concepts is the integration of major urban roads, because 70 to 80 percent of all urban accidents occur on major roads. Traffic calming which is primarily based on the locational shift to such main thoroughfares is socially injust, because — in spite of all disturbances on those streets — about one quarter of the urban population live there. Social justice can only be somewhat achieved if the expenditures for traffic calming and streetscaping are not used — as today is most common — for accumulating the advantages in the low traffic side streets, but aimed at a partial balance and compensation for the strains caused by car traffic on the major streets. Some compensatory measures and new design principles will be discussed. Backgrounds are the experience in six German model cities of area-wide traffic calming, several research projects and the discussion about new guidelines for major urban roads. Where traffic and environmental burdens focus, the concentration concept should be extended by compensatory measures. That is the state of discussion in Germany examplified by nine topics.This is an edited version of a speech presented by the author at the International Conference Living and Moving in Cities in Paris, January 1990.     

Special issue: Importance of public transport

The transport demand in most major cities around the world can only be met with a high‐quality public transport system. The requirements on bus, rail, underground and tram systems are manifold with reliability and efficiency as the key factors. The service operating hours and the size of the network are often extended in order to serve the needs better. Further, most metropolitan areas are trying to provide more incentives for citizens to leave the car at home and use the local transit systems instead. The reasons are well known. Not only does a public transport system only make economical sense if it is well used, but most urban areas with a high car‐dependency face at least three major problems; safety, congestion, and pollution (noise and air pollution, land separation, etc.). It is generally recognised that to decrease car usage and to increase public transport usage a stick & carrot approach is needed. The London congestion‐charging scheme is an example since all revenues collected by the scheme are put into the improvement of bus and underground services.     

Behavioral monitoring of public transport users through a mobile communication system

There are various activities now taking place in ITS research and development in Japan. Advanced information and communication technologies have been applied to improve public transport systems, as well as automated highway systems. In the first part of this paper, we show three examples of public transport systems recently developed in ITS environment. These transport systems are operated in local cities and towns in Japan: the travel information system for tram users in Hiroshima, the demand responsive bus system in Nakamura and the co‐operative use of electric vehicle in Ebina. In the second part of the paper, we explain how we have monitored individual passenger on public transport using cellular phones for location positioning. Location positioning technology for mobile object is essential for the operation and management of ITS supported public transport systems. Furthermore, such accurate and detailed positioning data can be utilized for travel behaviour analysis in demand modeling. The mobile instrument and monitoring systems shown in this paper can be combined with any of the case studies of ITS application to public transport systems.     

Reflections on citizen involvement in urban transportation planning: Towards a positive approach

The purpose of this paper is to explore an important and unique role which community participation and involvement can play in a revised transportation planning process. A review of diverse views about community participation, as well as a critique of the current urban transportation planning process, reveals that the former has played, primarily, ad hoc opportunistic and diverse roles, and that the latter is in desperate need for dynamic, subjective, impact information — required to assess attractive transportation systems. The contributions of several disciplines — economics, operations research, management science, political science, public administration, and others — are reviewed to assist in the development of a conceptual framework for a new community participation role, as a provider of key information to the planning process. An eclectic, experimental approach is recommended to explore the possibilities further.     

Redistributive effects of subsidies to urban public transport in Spain

This paper analyses the redistributive effects generated by the subsidization of urban public transport services. We estimate a two-stage model that takes into account both car ownership decisions and expenditure in urban public transport. In this way, we are able to measure the long run effects of income changes. Under the assumption that the user is the final beneficiary of the subsidies, and computing the share of the fare that is subsidized, we measure the progressiveness of the subsidies for different income groups and city sizes. Urban public transport subsidies are shown to be progressive. In larger urban areas this effect is considerably more important than in small ones.     

Transport reviews prize

The transport problems that urban centres now face (as regard congestion, the environment and public deficits) have led to an examination of competition in the sector. Some countries have moved towards the deregulation or privatization of urban public transport, influenced by developments in the theory of contestable markets. These analyses could potentially provide a means of increasing the efficiency of public services and, hence, public transport. However, the authors do not feel that they can deal with the full extent of the problem. Particularly in urban areas, there is a need nowadays to examine the issue of competition between the passenger car and public transport, especially from the pricing angle. In France, decades of policy strongly influenced by a preference for the car have prevented this problem from being a central concern for researchers and decision-makers. The approach to the problem has mainly been centred on increasing urban supply to meet demand better. However, a failure to consider pricing, and the subsidization phenomena that can occur as a result, affects the shape of supply systems. Pricing, through its action on demand, acts on supply by increasing or reducing its potential profitability. 'Snowball' effects can, therefore, mean that slight underpricing results in the domination of one transport mode. These effects have been revealed in particular by work in the new field of network economics. The example of the Lyon conurbation shall be used to illustrate the case, which is that car travel is underpriced. The basis of the exposé will be a detailed analysis of the externalities associated with the car, i.e. the costs of car use and the revenue it raises for the community. The second part of the paper is a study of several urban travel policies in Europe (France, UK, Switzerland, Italy) to show the 'effects' of this underpricing. Where supply has followed the pressure of demand, the dominance of the car has been reinforced. However, in cities, particularly in Switzerland, where supply has been restricted, this dominance has been considerably moderated. On the other hand, it can be seen from the French example that taking strong action to improve public transport is not in itself sufficient to increase usage. Several lessons can be learnt from this work. First, it is shown, if it was still necessary to do so, that the problems of urban travel require a comprehensive and coherent approach. Modal policy must, therefore, be assessed with reference to the entire transport system. Next, in connection with the issue of regulation, it is important to consider the issue of competition in urban areas, and not only competition between public transport operators, but also (and even above all) competition within the entire system of personal and public transport. Finally, with regard to pricing, the ratchet effects that benefit the car as a result of its underpricing in urban areas need to be studied.     

Fuel price changes and their impacts on urban transport – a literature review using bibliometric and content analysis techniques, 1972–2017

ABSTRACT

While the period of heightened oil prices in 2005–2014 has attracted considerable academic and policy attention, there is scant cross-disciplinary research considering energy price, transport and land use together. In car dependent societies many socio-economically disadvantaged areas often lack public and active transport accessibility. Emerging research focus has been placed on issues of transport equity including effects of fuel prices. We reviewed 45 years (1972–2017) of publications about fuel price impacts, transport, and urban context, drawn from Web of Science listed publications. Bibliographic citation analysis reveals eight major research clusters with a set of inter-city comparative studies at their centre. The historical evolution, geographical trends, research approaches and the key themes are revealed by context analysis. The paper highlights the need for further studies looking at energy, transport and land use interaction, and suggests a greater focus on transport equity.     

Urban passenger transport in the United States and Europe: a comparative analysis of public policies

This is the second part of a two‐part series that examines recent developments in urban passenger transport in the United States and Europe, focusing on the roles and impacts of the public sector as these have varied by country and over time. The first part of the series described public policies for roadway systems and private car use, whereas this second part concentrates on public transport. After a review of demand and supply trends, the article evaluates government policies in terms of public vs private ownership and operation, public regulation, financing responsibility by government level, types and amounts of subsidy, and impacts of ownership, regulation, and financing arrangements on costs and productivity. This second part concludes with an overall comparison between Europe and the United States, and considers how Europeans and Americans might learn from each other's successes and mistakes in order to improve transport policies.     

Japan's urban transportation system in the major transport spheres

The urban areas in Japan have undergone rapid changes in the last two and one-half decades. At the same time, the urban transportation system has been faced with numerous problems which need to be solved urgently. This paper presents the development stage and problems in the three largest metropolitan areas, designated as transport spheres, in Japan. Japan's problems in urban transportation are similar to those of most Western nations with regard to such issues as rapid urbanization, growth in travel, increasing auto ownership, growing transit operating deficits, rising wages and air pollution. The differences are the large modal split of transit from automobile trips, major expansion of the rail transit network, and the large number of transit operators in each urban area in Japan. In addition, governmental policies to help solve the urban transport problems are briefly described. In order to make the policies effective, coordination among government agencies is required. The establishment of a unified government agency is regarded as the first priority in dealing with the urban transport problem. It is expected that the government will offer bold new countermeasures to cope with urban transportation problems.This report was accomplished with the kind assistance of Professor Jerry B. Schneider, Departments of Civil Engineering and Urban Planning, University of Washington, and Mr. Satoshi Inoue, an official of the Ministry of Transport in Japan, who is currently studying at the University of Washington.
