Knowledge for policy-making in times of uncertainty: the case of autonomous vehicle model results

Carey Curtis, Sam McLeod, John Hultén, Fredrik Pettersson-Löfstedt, Alexander Paulsson and Claus Hedegaard Sørensen, Transport Reviews, December 2020

There has been a rapid rise in papers modelling the impacts of autonomous vehicles. Drawing on a review of this literature, we analyse and discuss the messages conveyed by these studies from a policy-making perspective. An overview of the studies is provided to highlight the different policy frames. We consider the roles that modelling knowledge should have in policy-making in the context of unstable and uncertain futures where novel transport modes bring into question the use of past knowledge and assumptions. We conclude that both limitations of, and assumptions in, models need to be made more explicit and accessible when used in policy-making.

Replacing regional bus services with rail: Changes in rural public transport patronage in and around villages

Joel Hansson, Fredrik Pettersson-Löfstedt, Helena Svensson and Anders Wretstrand, Transport Policy February 2021

Removing bus stops is often a prerequisite for introducing faster, more reliable, and more frequent rail or coach services in rural areas. Despite the potentially higher quality of service through trains or coaches, however, the bus-stop removals often become stumbling blocks. It is sometimes feared that the alterations to the public transport network will pose a threat to the possibilities of living in rural areas outside villages. In this study, we investigate how travel by public transport is affected in areas where bus services are substantially reduced in connection with the introduction of rail services with fewer stops. Through an analysis of access trips from rural areas surrounding the train stations, we are able to study the development of public transport patronage in these areas in comparison with a control group with retained rural bus services. A total of 28 villages with surrounding rural areas in southern Sweden are included in the study. Our results reveal a significantly larger patronage increase around new train stations compared to areas where regional bus services are kept, and importantly, the patronage increase does not only occur in the immediate surroundings of the stations. Outside the villages, in the rural areas where public transport services have been cut, the increase is of equal magnitude. Hence, our results oppose the idea of distortion between the villages and their surrounding rural areas, at least in terms of net effect on public transport usage.

Governance reaction to the emerging megacity shrinkage in Tokyo: The case of the Tsukuba express transit-suburban region

Eigo Tateishi, Kyoko Takahashi and Taku Nakano, Cities, November 2020

This article provides insight into how the governance system of megacities, as an assemblage of many different factors, can preemptively react to emerging shrinkage. This is a topic that is rarely addressed in the current literature. The article examines the suburban region of the Tokyo Megacity served by the Tsukuba Express. The region is studied both quantitatively and qualitatively using a mixed-methods approach, and the results are related to the governance system model as originally developed. The results suggest that shrinkage-preemptive governance involves a mix of pro-growth and shrinkage-adapting strategies, but that implementing such strategies through interpolicy and intermunicipal coordination is problematic in growing metropolitan suburbs. We suggest (1) the national government plays a role in interpolicy coordination and regional governance of shrinkage, (2) the formation of political consciousness around regional transit infrastructure to foster regional coordination, and (3) a regional effort to restructure regional socio-economic identities to mitigate dependence on Tokyo and enhance economic resilience. This study shows that governance system models can assist planners and policymakers in engaging with the complexity of post-growth urban challenges.

Is it expensive to be poor? Public transport in Sweden

Anders Bondemark, Henrik Andersson, Anders Wretstrand and Karin Brundell-Freij, Transportation October 2020

One of the reasons to subsidise public transport is to improve the mobility of low-income groups by providing affordable public transport; however, the literature describes a situation whereby those with a low income are unable to afford the cheapest tickets per trip, i.e. travelcards, as they usually require a considerable up-front cost. In this study, we use a large dataset from the Swedish National Travel Survey to investigate whether, and if so how, income explains monthly travelcard possession among individuals for whom this would have been the least expensive option. We find a robust positive relationship between income and travelcard possession among low-income earners, indicating that those with a low income pay more to use public transport than more affluent individuals. As the accessibility of low-income groups is an important motivation for public transport subsidies, the findings from this study have important policy implications.

Policies for Reducing Car Traffic and Their Problematisation. Lessons from the Mobility Strategies of British, Dutch, German and Swedish Cities

Tom Rye and Robert Hrelja, Sustainability, October 2020

The objective of the paper is to explore whether particular problematisations of cars and car use lead to sets of solutions that may not deal with all problems associated with car use, and whether this leads to any internal conflicts within the chosen policies. The paper is based on a review of local transport policy documents from 13 cities in four countries using the lens of policy problematisation as an analytical framework. Some critiques of policy problematisation are discussed in the paper but it is nonetheless shown to be helpful for this analysis. The paper finds that the problems most typically highlighted in the strategies reviewed are poor accessibility (as a “bad” in itself, but also because it is seen to compromise economic growth); the negative impacts of traffic on liveability of the central part of the city and therefore its ability to attract inhabitants, especially those needed to support a knowledge economy; local air and noise pollution; and road safety. The resulting visions are for urban areas less dominated by private cars, with more green and public space, in order to maximise accessibility and liveability to attract economic development; and most cities also seek to reduce car travel as a proportion of trips. However, in many cities this vision covers mainly the central city, with car use set to remain dominant in outer cities and for regional trips. In almost all cities, only one measure, parking management, is proposed as a means of cutting car use. The differing sets of measures envisaged for outer areas of cities threatens to undermine those envisaged for more central cities.

Shaping sustainable travel behaviour: Attitude, skills, and access all matter

Zahra Hamidi and Chunli Zhao, Transportation Research Part D: Transport and Environment, November 2020

Drawing on the conceptualisation of motility as the capacity to be mobile, this paper employs statistical and GIS-based analyses to explore the associations between travel mode choice and mobility-related attitudes, skills and opportunities to access transport modes. The study builds on survey data and spatial data from three urban contexts of Beijing, Gothenburg and Malmo to analyse both individual-level and contextual factors influencing sustainable travel behaviour. The results indicate that despite varying contexts, the three dimensions of attitude, skills and access significantly explain individuals’ travel behaviour and their choice to travel by public transport, bicycle or car. Among the studied travel modes, cycling appears to be a competitive mode when the travel distances are within 5 km. In all three urban contexts, individuals who have greater environmental awareness are more likely to travel by public transport or cycling if the physical conditions facilitate using these modes. Good access to public transport is likely to increase the usage of both cycling and public transport and reduce car use. Favourable conditions for cycling within 2 km and 5 km radius can positively encourage people to use a bicycle as a feeder mode for public transport. Overall, our findings demonstrate that for mobility policies to increase individuals’ motility in relation to sustainable travel modes and encourage a travel behaviour shift towards using alternatives to cars, planners need to take more holistic approaches and design policies that deal with the three motility dimensions in an integrated manner and avoid focusing on a single dimension in isolation.

The knowledge problem of public transport policy

Erik Johansson, doctoral thesis, September 2020

The overall aim of the thesis is to investigate the knowledge problem in regional public transport planning. The knowledge problem is twofold. How do transport policy arrive at the desirable actions they take and how do they assess the alternatives, and what can we say about the contributions of already implemented transport schemes. Paper 1 explores how policy objectives in regional public transport are translated into action and to investigate how public transport measures are evaluated. Paper 2 presents a case study of Spårväg syd, a light rail project in Stockholm, with the ambition to understand the use of appraisal tools and discuss how these can be improved. Paper 3 investigates the links between accessibility, as well as the composition of accessibility and real estate values. Paper 4 analyses the causal effect of a train station on local labour income among current residents as well as the labour income of the residents that the place attracts. Finally, paper 5 explores the association between the accessibility that train stations provide and local labour income more broadly across Sweden. For paper 1, the results indicate that decision-makers ask for knowledge on ongoing trends such as patronage and market share in relation to all motorized transport, an increased interest in understanding the impacts of transport on society, the strategies of PT are connected to long term regional ambitions. Paper 2 highlights that particular projects are tightly connected to long term ambitions. Spårväg syd was on the agenda long before a formal cost-benefit analysis was conducted. The project is also tightly connected to political goals of land-use development. The findings from paper 3 reinforce the evidence that real estate values are positively associated with accessibility. Also, the paper finds that the composition of accessibility, namely the degree to which the accessibility is built up by one or several modes of transport, is positively associated to real estate values as well. The policy implication of this finding is that transport appraisal could add assessments not only of marginal accessibility changes, but also the marginal change in the composition of accessibility. The results from paper 4 indicate an absence of a causal link between train stations on local labour income. Both in terms of the longitudinal analysis and the spatial sorting analysis. For paper 5, accessibility through the national railway network was found to be associated with local labour incomes. The thesis increases the evidence of effects of transport on income and real estate prices. Moreover, the thesis concludes that regional public transport planning seems to be subject to different motivations and trade-offs depending on project and context, which complicates the seeking for a universal appraisal procedure.

Flexibility in contract design: is that possible?

Carolina Camén, Panagiota Tsaxiri, Malin Aldenius and Helene Lidestam, ScienceDirect, July 2020

Public procurement is widely used in order to incorporate competition into public services. Competition in procurement often leads to efficiency but the process can also raise some problems. While providing the procurement documents you do not know who will be your upcoming partner. Another aspect is how flexibility can be managed in contract design while maintaining a high service quality. The aim of this study is twofold. Firstly, the aim is to investigate how flexibility has been expressed and historically described in bus tendering documents. Secondly, to explore how the actors define or describe flexibility and its importance in tendering. Data was collected from ten years of tendering documents in the bus sector in Sweden and from interviews and a workshop. The results showed that flexibility in tendering documents has been and still is low for the operators. However, the actors wish for more flexibility and new forms of contracts can make it easier to include higher degrees of flexibility in future contracts. The paper contributes to the ongoing discussion about how to design contracts and to manage flexibility. The study has potential to create knowledge and contribute to better decision making for future procurement of bus transport.

How much regulation should disruptive transport technologies be subject to?

Göran Smith and Walter Theseira, Research in Transportation Economics, August 2020

In recent years, the advent of disruptive transport technologies has started to transform the transport sector. Governments are therefore challenged to find the right balance in transport governance frameworks that allows new services, practices, and entrants to emerge, but also ensures adequate and equitable service delivery, a fair and competitive landscape, and fulfillment of policy objectives. Workshop five of the 16th International Conference on Competition and Ownership in Land Passenger Transport (Thredbo 16) focused on this challenge. Eight studies of governance approaches to ridesourcing, autonomous public transport, and Mobility-as-a-Service were reported. These examples catered for a discussion on the development status of disruptive transport technologies and on what roles governments have adopted, what types of regulations and policies they have been using, and what is known about the impacts of these approaches. Drawing on this discussion, the workshop advocates transport scholars to work on the theoretical grounding of key concepts and to elicit empirical evidence from trials and operations on disruptive transport technologies’ effects on e.g. equity, employment, and modal shares. To governments wishing to facilitate the development and diffusion of disruptive transport technologies, the workshop offers ten recommendations that in sum describe an explorative, collaborative, and reflexive governance approach.

Improving Coherence in a Cross-Border Public Transport System: Lessons from the Greater Copenhagen Region

Jean Ryan and Anders Wretstrand, Sustainability, August 2020

Greater Copenhagen is often cited as a good example of cross-border cooperation. Shared historical contexts and socio-political willingness have meant that considerable resources have been invested into the development of infrastructure in this region. The Öresund fixed link constitutes the most important element of this infrastructure, facilitating a cross-border public transport system which ties the region together. This public transport system in turn underpins the social, economic and environmental sustainability of the cross-border region. The aim of this study is to investigate the issues at play with respect to improving the coherence of this cross-border public transport system, in relation to ticketing and public transport information in particular. This study comprises the compilation and analysis of the perspectives of the actors involved in and affected by the development of the cross-border transport system. In total, twelve semi-structured interviews were conducted. Six predominant themes emerged from the analysis of the empirical material: “Focus on the customer”, “The Other Side”, “Tidying up at home first”, “Political challenges”, “Back to basics” and “The low-hanging fruits”. It became apparent that the prioritization of internal and organizational issues in the first instance could mean compromises, not only for cross-border cooperation but also for the customer’s (the passenger’s) experience. Results suggest that improvements to coherence in this transport system will most likely take the form of incremental changes and adopting common standards. This is opposed to the development of common systems, or of a significant departure from existing systems.
