Background The COVID-19 pandemic has rapidly led to some of the most revolutionary changes in private and professional life around the world. While the extent and duration of these changes are not certain, they have already had a great impact on travel patterns. This is also the case in Sweden, despite its relatively liberal approach to restrictions, which relies on voluntary measures such as social distancing and self-monitoring for symptoms. Methodology Due to the pandemic, a shift to telework and virtual meetings is being tested in what can be seen as a large-scale experiment, and the knowledge and experience from that experiment may have lasting effects on everyday life. This study seeks to analyse the effects of government and public agencies’ recommendations on meeting and travel behaviour on employees at five public agencies in Sweden. Results The results indicate that the public authorities surveyed were well prepared and had a ‘backup collaboration solution’, at least technically, to make a rapid behavioural shift when travel was not an option. Though the Swedish government’s and Public Health Authority’s strong recommendations have led to the most dramatic reductions in work-related travel in modern times, the operations in Swedish agencies continue to function, along with the employees’ communications and collaborations. These results indicate that there is great potential for digital tools to influence if and how we commute and make business trips. The COVID-19 pandemic has shown that such tools can make the impossible possible.

As sales of e-bikes increase, so does the need for reliable evaluations of which means of transport the e-bike replaces, what we call the substitution effect. A randomised controlled trial with GPS data from 98 frequent drivers in Sweden was conducted to investigate the effect of the e-bike on modal choice, the number of trips, distance, as well as perceptions of the e-bike as a substitute for the car. The results demonstrate that the treatment group increased cycling on average with 1 trip and 6.5 km per day and person, which led to a 25% increase in total cycling. The whole increase was at the expense of car use, which on average decreased by 1 trip and 14 km per person and day, a decrease in car mileage of 37%. Implications for policy and further research are discussed.

Research into the bicycle level-of-service (BLOS) has been extensively conducted over the last three decades. This research has mostly focused on user perceptions of comfort to provide guidance for decision-makers and planners. Segments and nodes were studied first, followed by a network evaluation. Besides these investigations, several variables have also been utilized to depict the users’ perspectives within the BLOS field, along with other cycling research domains that simultaneously scrutinized the users’ preferences. This review investigates the variables and indices employed in the BLOS area in relation to the field of bicycle flow and comfort research. Despite general agreement among existing BLOS variables and the adopted indices, several important research gaps remain to be filled. First, BLOS indices are often categorized based on transport components, while scarce attention has been paid to BLOS studies in trip-end facilities such as bicycle parking facilities. The importance of these facilities has been highlighted instead within research related to comfort. Second, the advantages of separated bike facilities have been proven in many studies; however, scarce research has addressed the challenges associated with them (e.g., the heterogeneity within those facilities due to the presence of electric bikes and electric scooters). This issue is clearly noticeable within the research regarding flow studies. Furthermore, network evaluation (in comparison to segment and node indices) has been studied to a lesser extent, whereas issues such as connectivity can be evaluated mainly through a holistic approach to the system. This study takes one step toward demonstrating the importance of the integration of similar research domains in the BLOS field to eliminate the aforementioned shortcomings.

This study investigates the influence of pedestrian crowdedness on e-bike navigation behaviour in a controlled field experiment. The dataset includes a total of 1520 trajectories, including 18 pedestrians and one e-bike at a time. Based on the e-bike navigation through the pedestrians, the so-called “hindrance” concept was used to classify the data into two phases: passing (same-direction encounters), meeting (opposite-direction encounters). E-bike speed and its lateral position within the pedestrian crowds have been quantified to compare the passing and meeting phases. The results show that, the e-bike generally maintains an average speed during the meeting phase regardless of pedestrian crowdedness; however, the e-bike slows down in a linear trend when pedestrian crowdedness increases during the passing phase. Furthermore, the e-bike during the meeting phase has less lateral displacement compared to in the passing phase, which could be the consequence of the aforementioned speed and crowdedness relationship. The findings have applications for the e-bike level-of-service studies and also the design of bike tracks and sidewalks when there is mixed traffic of e-bikes and pedestrians.

This study explores marketing messages promoting sustainable transport and reported motivation to reduce private car use within different segments. A stated preference survey targeting a sample of 1300 residents in Sweden was conducted, and exploratory factor analysis was used to identify underlying dimensions of a set of 19 marketing messages. Self-efficacy and collective efficacy were defined as latent factors, and the latter was found to be a better motivator for all segments. For the most car-advocating segment, however, the factors (both self- and collective efficacy) was unsuccessful in inducing any reported motivation to reduce private car use. Assimilation bias seems to influence the respondent's interpretation of marketing messages.

Business travel contributes to significant greenhouse gas emissions, and there is a need for measures that reduce the demand for trips made with energy-intensive means of transport. In this study, a mobility service application (MSA) introduced in 13 Swedish organisations was tested and evaluated to facilitate booking and handling of business trips, in particular public transport. A before and after study consisting of surveys and interviews with employees at the organisations were conducted. The results show that the MSA was mostly used for regional and local public transport trips, and the users stated that the MSA made it easier to travel by public transport, although this particular result should be seen as tentative due to the small sample size. Three factors that influence the success of a new MSA as a means to increase sustainable business trips were identified: management control and proactiveness; perceived improvement of intervention; functions and technical sufficiency. The results also highlight the need to establish organisational conditions that facilitate sustainable business travel, such as coherent travel policy, accessibility to sustainable modes of transport, and a culture that encourages environmentally friendly behaviour. The study suggests improvements that can be made to similar interventions and strategies that can be introduced to promote sustainable business travel.

There are large discrepancies in the transport sector along gender lines in travel patterns and means of transportation used, but also in attitudes and norms among citizens, planners and decision-makers, with women generally more positive towards measures involving the lowering CO2 emissions. At the same time, the number of women involved in transport-related decisions is low. This is a problem for gender equality but possibly also for sustainability. A careful review of previous studies indicated a lack of analyses on the subject based on quantitative data at the local level. We investigated a possible link between women’s presence in local policymaking and more sustainable transport policies, and whether it is possible to capture such an effect. The main contribution of this paper is a methodological approach in which, besides generating unique data on representation in municipalities (confirming men’s dominance, specifically in transport policymaking), possibilities for quantitatively measuring gender and the level of sustainability in transport planning are discussed and tested. Challenges in collecting relevant data and analyzing possible covariances in the data set are discussed and presented as well as suggestions for further investigations into the possible link between gender and sustainable transport performance.

Globally, transport increases its share of emissions and the transport sector desperately needs an efficient climate policy including efficient strategies to reduce unsustainable levels of car use. By providing insights into the profile of passenger mileage by car in relation to levels estimated to be sustainable in 2050, this work gives insight into who will, and who needs to, be affected by policies and measures to achieve climate goals. The study, using Swedish national travel behaviour data, in line with international research, shows that a minority produces the majority of all passenger mileage by car. Adding an analysis of the national attitudinal study to the national travel behavioural data reveals that the high mileage producers further belong to groups with a low inclination to adopt sustainable behaviour, i.e. men, the middle aged and frequent car users. Policies and measures proposed to reduce unsustainable levels of car use need to be tailored to those groups in order to be efficient.

The negative effects of transport in terms of pollution, congestion and climate change has urged the need for higher shares of cleaner and more efficient modes of transport, especially in urban settings. While new technology can solve some of these issues, behaviour changes has also been identified as an important factor to achieve a modal shift from cars to walking, cycling or public transport. This study investigates how ICT has been used to influence behaviour change and synthesizes key aspects into a conceptual model for creating a behaviour change support system (BCSS) for smartphone applications. A literature review concerning behaviour change and ICT in the fields of transport, health, energy and climate was conducted to gather empirical evidence which forms the foundation of the conceptual model. The empirical findings were tested and verified against a theoretical framework consisted of The Transtheoretical Model, Theory of Planned Behaviour, Diffusion of Innovations and the concept of Gamification. The results suggest that customization to the user, relevant and contextualised information and feedback, commitment, and appealing design are important aspects when influencing users to behaviour change through smartphone applications. The conceptual model provides further knowledge of key aspects to consider when developing persuasive tools that aims to encourage more sustainable modes of transport.

There is a clear need for debate about targeted policies to address individual behaviour and car mileage. In this study, the point of departure is that we need more knowledge regarding travel behaviour focusing on the needed reduction in car mileages. The study illustrates a series of travel behaviour analyses that can be applied in any other country striving for more detailed knowledge of the challenges ahead regarding reductions in car mileage. The focus is on passenger mileage by car in relation to the level of passenger mileage by car estimated by the Swedish Transport Administration for a sustainable transport system by 2050. Four distance categories are defined and used. The results indicate that on an average day, the overwhelming majority of total passenger mileage by car (>90%) is produced by a minority of the population (25%) and only approximately half of the population use a car on an average day. There are differences between rural and urban areas, but for the category of high passenger mileage by car, the difference is not remarkable.

In planning for a future sustainable transport system, it is important to consider the likely effects of e-commerce. This paper analyses the understanding of impacts of e-commerce on urban planning as expressed in planning practice in a number of Swedish municipalities. Knowledge claims concerning the potential effects of e-commerce are studied through an analysis of planning documents and supplementing interviews. These knowledge claims in planning practice are contrasted with the findings presented and discussed in the research literature. The results indicate that the current understanding of e-commerce in Swedish planning practice is limited and that it is primarily viewed as an opportunity to address transport system issues by reducing passenger transport. However, the overview of the literature shows that e-commerce has so far only had limited effects on prevailing mobility habits and that freight transport has increased in parallel with increased e-commerce. Furthermore, e-commerce challenges city centres as commercial areas. Thus, from a planning perspective e-commerce should not be regarded as an easy solution for an unsustainable transport sector. To harness its potential benefits, there is a need to develop pro-active planning strategies that address the potential impacts of e-commerce.

Purpose The Swedish government is likely to implement longer and heavier road freight vehicles, so-called high-capacity vehicles (HCVs), in the near future. The purpose of this paper is to analysis the expected effects on the whole transport system regarding tonne-kilometres, vehicle-kilometres on road, CO2 and socio-economics with three possible implementation strategies (HCVs on all roads, a designated road network and a designated road network with a kilometre-based truck charge) and two vehicle types (74 t/25.25 m and 74 t/34 m). Design/methodology/approach Calculations are based on two well-established scenarios for transport development in Sweden. Changes per tonne-kilometre are modelled for ten product groups with considerations taken to their transport networks. Socio-economic effects are analysed using the net present value rating method over a 40-year period. Findings The study shows the increase in demand for transport and the modal shift, from rail and sea to road, in terms of tonne-kilometres, vehicle-kilometres and CO2 emissions for three implementation strategies of HCVs in two scenarios. All implementation strategies show a positive social net-benefit with the introduction of HCVs. Research limitations/implications The results reveal potential benefits to the implementation of HCVs. The results are limited by possible over/under-estimations of effects considered in the calculations, due to uncertainties and assumptions. Practical implications The results highlight expected levels of modal shift and induced transport for different HCV implementation strategies and how they depend on transport and climate policies and the expected growth of tonne-kilometres. Originality/value The calculations consider socio-economic effects, particularly from increased CO2 emissions due to modal shift and induced traffic, which is lacking in previous studies. To balance conflicting economic and environmental goals, the findings indicate that the implementation of HCVs could be accompanied by other policy measures. The findings are based on the Swedish context, but the model can be adapted to other countries or regions and to study other freight transport reforms.

This paper analyses regional public transport planning in Sweden. The aim is to provide an insight into how policy objectives are translated into action and to investigate how public transport measures are evaluated. The analysis is based on interviews with civil servants in five Swedish regions. Cost-benefit analysis is sparsely used (if ever) and the results further indicate that planning and evaluation of public transport is to a large extent centred around monitoring on-going trends, e.g. patronage and market share. Such information seems policy-relevant, i.e. is commonly asked for by the political level. The informants do ask for more knowledge regarding various effects (mainly social). However, it is less certain whether or not this knowledge would be used for economic evaluation. Regional and local public transport systems are complex, and intrinsically linked to land use and long-term regional ambitions. Instead of asking how public transport planning should be carried out, following CBA analyses, we should perhaps ask how the economic analysis could be tuned so that it becomes relevant for public transport planning. We foresee that the broader role of the public transport system will increase goal conflicts between, and within, authorities.

Opportunities for online shopping are transforming travel behaviour related to shopping, and they have the potential to reduce overall travel demands. This paper analyses the potential for reductions in carbon dioxide (CO2) emissions from passenger transport due to an increased use of online shopping in Sweden and adds to the broader picture of what potential growing online shopping might have on transport sustainability. This paper shows that there is a sustainability potential related to more sustainable travel habits by those who shop online more frequently. Calculations indicate that the predicted increase in online shopping behaviour together with the predicted increase of the Swedish population in 2030 would give a 22% decrease in CO2 emissions related to shopping trips compared to 2012. Furthermore, if all travel is taken into account this would result in a 2% reduction in 2030 compared to total CO2 emissions 2012. The paper furthermore discusses how these results might influence transport sustainability ambitions and policies. The discussion suggests that online shopping might facilitate reductions in CO2 emissions but above all, it could act as a facilitator for implementing other policies promoting a less car dependent planning regime including shopping localisation

A full-scale congestion charging trial was carried out in Stockholm the first months of 2006. Almost half of respondents in a county-wide survey stated that they changed their attitudes towards congestion charges during the trial. Most of them became more positive. An analysis of media shows that the attitudinal change in media towards the trial coincides with the attitudinal change of the public. There was no dramatic change in the proportion of articles expressing a negative view. Instead, the result indicates that the increase in positive views was driven by a shift from neutral to positive articles during the trial. In order to ascertain why the public attitudes swung, we have analysed the anticipated and perceived effects of the trial. Generally, the analysis seems to indicate that improved understanding of the type and magnitude of concrete effects was not a main driving force behind the attitudinal change. Instead, it seems that the public attitude changed because personal experience gave a new understanding of the implications of the charges for the personal well-being. This would imply that trials, generally, may be a more useful tool than information in the process of implementing ‘difficult’ policy measures, such as congestion charges.

This article investigates whether the choice experiment approach can be used to assess people's preferences and the determinants of these preferences in order to estimate the costs and benefits of different configurations of the transport of hazardous materials by rail. Changes in the exposure to hazardous materials that people are subjected to are used rather than changes in accident risk. To the best knowledge of the author, this has not been done before in a study of people's preferences toward hazardous materials. A mail survey, carried out in two cities in Sweden, is used to obtain tentative estimates of the willingness to pay for a reduction in exposure as well as the willingness to accept an increase in exposure. Special attention is given to viability, since the complexity of the activity studied, transport of hazardous materials, and the method used pose particular challenges. The response rate and tests of validity and consistency indicate that this method can be applied. Moreover, the results suggest that studies of this kind may provide guidance on changes in the transport of hazardous materials, especially because policymakers may influence the attributes presented here. Referring to the exposure of hazardous materials highlights the importance of providing the respondents with adequate information regarding hazardous transports. An important finding is that the amount of background information may have some effect on the stated preferences

This paper estimates the relationship between accident frequency and the traffic flow empirically treating the hourly traffic flow in two different ways, as consisting of homogenous vehicles and as consisting of cars and lorries. Rural roads in Sweden are studied using Poisson and Negative Binominal regression models. It is found that important information is lost if no consideration is taken to differences between vehicle types when estimating the marginal effect of the traffic flow. The accident rate decreases when the traffic flow is treated as if homogeneous. However, when cars are studied separately the result suggests that the accident rate is constant or increases. The result with respect to lorries is reversed, indicating a decreasing number of accidents as the number of lorries increases.
