The value and effects of introducing high standard train and bus concepts in Blekinge, Sweden

A set of improvements were introduced on a railway line in the south of Sweden in January 1992, including a new train concept, improved timetable and lower fares. The new train replaced a combination of old rail cars and standard coaches (bus). Furthermore, 18 months later, a new high comfort coach (bus) service was introduced as a complement to the train timetable to increase the number of departures. Forecasts from a national four-step model system, based on Revealed Preference data, which did not cover explanatory factors like mode concept, comfort, mode image, was made and compared with a forecast based on stated preference data choice model. Both type of forecasts were compared to travel statistics. Stated Preference data have been collected from car drivers, coach and train passengers. The set of improvements have been included in the SP alternatives presented to the subjects. A structured logit model, a regression model and a linear programming model are compared. Unstructured and structured logit models are compared. Logit models have been estimated and used to form a mode choice model which predicts the changes in market shares between the train and car. The choice model forecast coincide, accidentally, with actual demand 8–9 months after the introduction of the set of improvements (a 40% increase in journeys). The set of improvements, including the new train service, has proven to be a success with more than 100% increase in travel after only two years of operation. Differences in estimated logit models for 1991 and 1992 are explained as partly due to asymmetry effects and partly to shortcomings in the SP data collection technique. Logit model estimates for train and coach are compared. The value of high standard coach service, running in parallel to the train, is estimated. The new coach gained few new passengers and also a much lower monetary value than the train by both train and bus passengers.     

A logistical perspective on the potential for modal shift of freight from road to rail in Great Britain

Freight modal shift from road to rail is a potential means by which the negative environmental and social impacts of transport can be reduced. This paper explores recent supply chain changes and assesses their impacts on the mode choice decision-making process, specifically addressing the implications for the use of rail. Despite many of the identified changes effectively making the use of rail more difficult, considerable evidence has been found of the potential for rail to attract new traffic. Much of the identified potential is unlikely to materialise, however, without improvements in rail network capability and capacity and a greater customer focus from rail freight operators.     

What future for light rail in the UK after Ten Year Transport Plan targets are scrapped?

Light Rail schemes were key components of plans to improve accessibility and personal mobility in conurbations as part of the UK Government's Integrated Transport Policy and its 2000 Ten Year Transport Plan. However by 2004 light rail's future in Britain looked bleak as sharp increases in capital costs, following the demise of Railtrack and the loss of private sector confidence, led Government to withdraw its part funding of light rail schemes in Leeds, Liverpool, Manchester and Portsmouth.This paper examines recent changes in Government urban transport policy; why the Ten Year Transport Plan 2000 target of doubling light rail journeys and supporting the opening of 25 new light rail lines was scrapped after just 2 years; the role played by the 2004 National Audit Office Report in enabling the Government to marginalise light rail outside London; ways of reducing light rail's capital costs, securing new funding sources and lessening dependence on Government finance; and why part funding of extensions to Greater Manchester's successful Metrolink light rail system has been re-instated.     

Demand-responsive transit circulator service network design

Commuter rail systems are being introduced into many urban areas as an alternative mode to automobiles for commuting trips. It is anticipated that the shift from the auto mode to rail mode can greatly help alleviate traffic congestion in urban road networks. However, the right-of-way of many existing commuter rail systems is usually not ideally located. Since the locations of rail systems were typically chosen long ago to serve the needs of freight customers, the majority of current commuter rail passengers have to take a non-walkable connecting trip to reach their final destinations after departing the most conveniently located rail stations. To make rail a more viable commuting option and thus more competitive to the auto mode, a bus feeder or circulator system is proposed for transporting passengers from their departing rail stations to final work destinations in a seamless transfer manner. The key research question with operating such a bus circulator system is how to optimally determine a bus route and stopping sequence for each circulating tour by using the real-time demand information. In this paper, we name this joint routing and stopping optimization problem the circulator service network design problem, the objective of which is to minimize the total tour cost incurred to bus passengers and operators with respect to minimizing the walk time of each individual bus passenger. A bi-level nonlinear mixed integer programming model is constructed and a tabu search method with different local search strategies and neighborhood evaluation methods is then developed for tackling the circulator service network design problem.     

The feasibility of introducing light rail systems in medium-sized towns in Central Europe

The article makes a case for introducing light rail systems in medium-sized towns and cities in Central Europe and analyses the feasibility of such a project. This is particularly important in the context of the paradigm of mobilities and the idea of sustainable development. Contemporary urban planning has yet to find a satisfactory answer to the question of how to diminish the negative consequences of individual transport without placing inordinate limitations on the natural human desire for mobility. It would seem that the increasingly negative effects of car use – for which bus transport provides no attractive alternative – are fast creating a need for a means of public transport that is not only separated from street traffic, but that is also effective and environmentally friendly. These requirements are met to the fullest extent by light rail systems such as trams, tram-trains and various hybrid solutions.     

How rural is too rural for transit? Optimal transit subsidies and supply in rural areas

The optimal supply of rail and bus in low density areas is studied by calibrating a demand and supply model with three modes (car, bus and rail) to an existing low density corridor. Varying the length of the network, the frequencies and the size of the populations, allows to study the trade-off between the consumer surplus losses of the public transport users and the transit operation and maintenance costs savings. We find that for an existing rail network, the optimization of frequency is the prime source of welfare gains. The rail network is marginally beneficial in the sense that keeping the network is welfare improving as long as there is no major repair or replacement investment needed. When population in the smaller towns decreases strongly, it becomes welfare improving to close the existing rail network but a bus service remains beneficial for at least part of the network.     

Identifying resident preferences for bus-based and rail-based investments as a complementary buy in perspective to inform project planning prioritisation

Much of the debate associated with the development of new public transport infrastructure appears to have an emotional bias with communities in favour of one mode, especially rail. This, in turn, carries much sway at the political level as if there is no budget constraint or consideration of value for money and coverage. This paper presents a stated choice experiment to investigate this context as two unlabelled options described by 20 potential drivers of community preferences for improved public transport. Each choice scenario is conditioned on a given route length but with different costs, reflecting different modal investment options for the same route length. To establish whether a modal bias exists within and between geographical jurisdictions, the choice scenario is followed by a labelling of each investment option to reveal whether the option is bus rapid transit (BRT) or light rail transit (LRT). Data from all eight capital cities of Australia, collected in mid-2014, form the empirical setting. Mixed logit random regret models provide new evidence on the nature and extent of community modal bias in this choice setting. The paper also proposes a complementary tool to benefit-cost analysis that uses the residence preferences model to show, through scenario analysis, the potential gains in public support for BRT over LRT. The results suggest that BRT should be in the mix of candidate projects if more than one mode is considered and not ignored, as is so often the case in developed economies.     

Deregulation and reform of rail in Australia: Some emerging constraints

The Australian Government over the last two decades has embarked on an intensive microeconomic reform program. Associated with this has been the deregulation of the rail sector. The mechanism of deregulation has been by vertically separating the below and above rail infrastructure and the creation of a number of rail access regimes. Evidence is emerging which indicates that the mechanism of deregulation is an impediment to the development of an integrated national network, the objective of deregulation and rail reform. This paper will discuss the mechanism of deregulation in Australia within the context of developments overseas. In particular it will discuss the development of a number of state specific rail access regimes and raise some problems and constraints being encountered in the reform process. The paper adds to a growing body of knowledge relating to infrastructure reform and deregulation and highlights some major constraints embedded in the model. The concluding section will discuss the relevance of past and current reform of Australian policies to rail policy makers outside Australia.     

Public bicycle as a feeder mode to rail transit in China: The role of gender,age, income,trip purpose,and bicycle theft experience

A marriage between public bicycle and rail transit presents new opportunities for sustainable transportation in Chinese cities. To examine determinants of public bicycle usage for rail transit access, an intercept survey of feeder mode choice among rail transit users was conducted near rail stations in Nanjing, China. Mode choice models were estimated with five feeder mode alternatives, including car, bus, walk, private bike, and public bike. By differentiating between public and private bicycle modes in the mode choice models, the study reveals the effects of personal demographics, trip characteristics, and station environments on public bicycle usage for rail transit access. Results show that female, older, and low-income rail commuters are less likely to use public bicycle to access rail transit. Rail commuters with bicycle theft experience and making school- or work-related trips are more likely to use public bicycle to access rail transit. Land use variables are largely insignificant in this study except that density shows a positive relationship with walking to rail transit. The results on demographic differences raise equity concerns when it comes to investing in public bicycle systems. Policy implications are discussed for Chinese cities to equitably boost public bicycle integration with rail transit.     

The UK public transport industry and provision of multi-modal traveller information

In recent years significant developments in transport policy have taken place in the UK. Public transport is considered key to the policy objectives of achieving an integrated and sustainable transport system. Improvements to public transport operations alone will not necessarily persuade people to forego the use of their cars and make use of public transport modes. Intending travellers need to be informed of what is available. Substantial activity, promoted by Government, is now taking place in the UK concerning traveller information systems developments. However, such improvements and developments are taking place in a difficult environment. The UK has gone further than any other European country in transferring its public transport services into private management operating under market forces. This paper provides an outline of the current form of the public transport industry (with a focus on bus and rail services) looking at the complex responsibilities and relationships which this entails. It then addresses the main national initiatives for integrated traveller information provision before setting out the issues facing decision makers and service providers in the light of public needs and consumer understanding.     

Improving bus bridging responses via satellite bus reserve locations

This paper presents a new method for assessing satellite bus reserve location to best service unplanned rail service disruptions by optimising location in relation to travel time to rail replacement, the volume of rail replacement incidents and the scale and spatial distribution of passengers affected.When rail disruptions unexpectedly occur, re-establishing network connectivity is paramount and the provision of bus bridging (or bus replacement service) is common. Minimising response times are critical in reducing impacts to affected commuters. Currently, reserve buses for such purposes are usually sourced from existing bus depot locations, which are generally situated to suit regular day to day operations. Strategically locating satellite bus reserves according to criteria such as disruption likelihood provides the opportunity to better cater for disrupted demand.The method is presented and analysis highlights how ideal depot locations within the network changes as consideration is given to travel time to locations where bus bridging commences, likelihood of a disruption warranting bus bridging and commuter volumes affected. The paper discusses the implications of findings for future research and practice.     

The use of mixtures of market and experimental choice data in establishing guideline weights for evaluating competitive bids in a transport organisation

The government sector is increasingly using competitive bidding for service deliveries such as the provision of bus and rail services as well as the purchasing of professional engineering services such as project planning, design, and project supervision. As part of a program to simplify and introduce consistency in the tender evaluation process, one government transport agency in New Zealand financed a study to investigate the potential of combined revealed and stated preference methods as a way of establishing weights to attach to the criteria used to evaluate offers of engineering services. These techniques have mainly been used in the study of travel choices; yet they have a much broader appeal in studying the decision making process of organisations. In this paper we use a data-mixing model to capture the decision expertise of a transport organisation through the revelation of preference weights for each evaluation criterion. Using choice information based on both market-driven and experimentally derived choice sets, we should be able to increase the robustness of the evaluation weights in comparison to the weights obtained from single data-sourced models. The resulting parameterised tool can be used in subsequent tender evaluations to provide an additional source of advice to supplement or replace that provided by current members of a bid evaluation team.     

Coordinated capacity and demand management in a redesigned Air Traffic Management value-chain

We present a re-designed European Air Traffic Management value-chain, with a new role for the Network Manager, which coordinates capacity and demand management decisions, using economic instruments for both areas. A conceptual and mathematical model supports decision-making in that process, focusing on capacity management decisions taken at the strategic level. Total costs are minimized by jointly managing sector-opening schemes and trajectory assignments. A large-scale case study demonstrates clear trade-offs between the volume of capacity ordered and the scope of necessary demand management actions. In addition, the comparison against a baseline, which resembles the current system, shows that with the proposed concept less capacity is needed to serve the same demand, resulting in lower total cost for Aircraft Operators.

Funding for local authority transport and land-use schemes in the UK

This paper focuses on the research activities, findings and planned products of one of the UK EPSRC-funded DISTILLATE (Design and Implementation Support Tools for Integrated Local Land use, Transport and the Environment) projects on the funding of transport and land-use schemes. Research activities have included a literature review, dialogue with local authority case studies and a funding workshop. The research identified and explored a range of barriers to funding, including lack of revenue funding, difficulties in obtaining funding for ‘soft’ schemes, the formation of partnerships and timing-related issues. The research also revealed that the funding system is failing to meet the needs of the current transport policy focus on managing travel demand, rather than being a supply-led process. The key project outputs are described, which include a ‘funding toolkit’ for local authorities, and guidance for funding bodies regarding the barriers faced.     

Port choice and freight forwarders

In light of the growing supply chain power of 3PLs and very limited empirical studies on port choice from the freight forwarders’ perspective, this paper tries to evaluate the major factors influencing port choice from the Southeast Asian freight forwarders’ perspective, their decision-making style and port selection process and draw out some policy implications for port operators and authorities. Efficiency is found to be the most important factor followed by shipping frequency, adequate infrastructure and location. Their selection process is complex and a two-stage process and supports the new approach that models ports within the framework of a supply chain.     

Dealing with demand forecasting games in transport privatization

Privatization has increased the number of players in the decision-making process for major transport investment decisions. The main argument of this paper is that this fragmentation is creating opportunities for strategic decision-making by each actor and that this is particularly obvious in the context of demand forecasting. This paper explores some of the specific causes and consequences of this new situation, including the perverse incentives, linked to the diversity of the objectives across the actors and to the risk allocation induced by the regulatory regime. It illustrates the issues and possible solutions from a wide range of modal and country experiences. In particular, it discusses the role of the newly independent sector regulators in reconciling these diverse goals and their limitations in view of the major information asymmetries problems they face.     

Evaluation of wider economic impacts of light rail investment on cities

Transport plays a critical role in facilitating competitiveness in post-industrial economies. High quality transport services and infrastructure enhance internal and external connectivity. This research examines published and unpublished evidence of economic impacts of modern light rail (tram and light metro) systems in the United Kingdom and globally. Evidence is considered relating outcomes of investment in light rail systems to: unlocking previously hard to reach sites for development; triggering fresh growth through elimination of significant transport constraints; stimulation of inward investment; extension of labour market catchment areas; reorganisation or rationalisation of production, distribution and land use; and land and property value increase and capture. Urban light rail investment can help regenerate Central Business Districts and boost employment and property prices. Similar rail investments in different locations may not however have the same economic impacts — geography matters. Other conditions in addition to transport investment are required for positive externalities.     

Autos,transit and bicycles: Comparing the costs in large Chinese cities

This study compares the full costs of seven passenger modes in the large Chinese cities facing the difficult yet crucial choice among alternative passenger transportation systems. The seven modes are evaluated at varied traffic volumes in hypothetical radial and circumferential commuting corridors. Using detailed estimates of private and social costs, the full cost of each mode is minimized by optimizing infrastructure investment and operation plans. On all corridors and across different scenarios, commuting by one or more forms of bus transit or bicycle costs less than automobile or rail. Nonetheless, in circumferential corridors, rail can be almost as cost-effective as bus under certain conditions, and bicycle can be less cost-effective than bus in some cases. Unlike results from similar studies conducted in the US, automobile commuting does not cost less than bus transportation at low traffic volumes.     

R-Tresis: developing a transport model system for regional New South Wales

This paper sets out a demand modelling framework for the development of a regional transport and land use model system (R-Tresis), to be implemented for New South Wales (Australia). Traditionally, the focus of such a model system has been major metropolitan areas such as Sydney, where we have developed Tresis (Hensher, 2002). Given the growing concern about regional accessibility to many service classes, there is a need for a modelling capability that can be used to prioritize and guide policy decisions in regions that are often described as remote, rural, low density and small town. In developing a framework that is capable of integrating both demand and supply elements of transportation and land use activity, we recognized the challenges in developing primary data sources, and the high likelihood of a reliance on secondary data sources. This suggested an alternative approach to demand modelling that was not dependent on choice models; namely a suite of continuous choice models in which we capture the actual activities undertaken by each mode on both the demand and supply side at high spatial resolution.
