To fulfil the global sustainable development goals (SDGs), achieving sustainable development is becoming urgent, not least in the transportation sector. In response to this, the sustainability framework Sustainability National Road Administrations (SUNRA) was developed to contribute to improving the sustainability performance of national road administrations across Europe. In the present study, the framework has been tested, applied and further developed to be applicable for target setting and follow-up at the project level at both the Swedish Transport Administration (STA) and at municipal levels. The aim was a framework relevant for investment, re-investments, maintenance and operation projects and also to make it more user applicable. The study also investigated how the framework can contribute to sustainability, identified drivers and barriers for applying the framework and examined whether the framework can be applied and adapted to projects of different complexities. The adaptations and developments were done in collaboration between researchers and practitioners. The results show that the framework could easily be used and adapted for investment, re-investment, maintenance and operation projects in the planning stage, as well as for small municipal establishments, construction or reconstruction of residential areas and frequent maintenance. The framework contributes to increased awareness on sustainability, and it provides a common structure and transparency on how infrastructure project goals/targets are set and fulfilled. The framework can also be applied to follow the fulfilment of the goals/targets and thereby adapt the project to better fulfil the goals. Identified barriers include the lack of obligations and lack of experience in using sustainability frameworks.

Even if the greenhouse gas emissions are rapidly reduced, the ongoing climate change will result in extensive and costly climate-related events that will occur more frequently. The costs in the Swedish transport sector for such events damaging streets, roads, rail/railways, and other vulnerable parts of the infrastructure are high today and are expected to increase. The consequences of weather-related events are, among other things, reduced accessibility, and increased risk of accidents. To maintain the functioning of the transport system, it is important to undertake risk-reducing measures related both to today's climate, but above all, to manage future climate-related events. It is necessary to ensure the functioning of the transport system during extreme weather events, and during periods of prolonged precipitation, prolonged heatwaves and changing precipitation patterns. It is also important to enable adaptation measures to deal with long-term changes such as rising sea levels which affect the accessibility and lifespan of the infrastructure.

This report presents a summary of results and a summary of how a framework for evaluating climaterelated impact relationships has been used. Effect relationships refer to identifying, assessing, and evaluating climate-related risks and risk reduction measures. In this report, the focus is on identifying, assessing, and evaluating the effectiveness of climate-related measures. The results is a framework for assessing the effect of risk-reducing measures, i.e., to assess whether it is relevant to implement a measure, when in time it should be implemented and to assess which measure is most relevant to implement. The risks have considered in case studies and include fire risk, risk of accidents on streets and roads due to zero crossings or heat, flooding, erosion and landslides and impact on road construction (rutting, bearing capacity and fatigue), track buckling and risks related to high winds. The tests have included hazard and risk identification, risk analysis, identification, and evaluation of possible measures. Examples of case studies are a torrential rain in Kungsbacka municipality in 2019, erosion-related changes over a long period of time at Österdalälven and calculations of climate impact on the road construction at the E10 at Svappavaara. A case study has also included monetary valuation and sensitivity analysis. The framework has also formed the basis for a discussion regarding climaterelated risks linked to electricity supply.

SUNRA (Sustainability: National Road Administration) SUNRA is a decision support tool developed to be used in road projects by setting the level of ambition for different sustainability aspects and following up the work towards these in a structured way. 

This memo describes how to use SUNRA, followed by a chapter with suggestions on where in the planning process SUNRA can be used, followed by chapters presenting the themes and aspects that are considered within SUNRA and the underlying issues that constitute the result of the updates made in this version. 

In this version, SUNRA has also been sued against the global sustainability goals as well as the Swedish Transport Administration's interpretation of them in Målbild 2030. SUNRQ aims to use it to contribute to sustainable development with a higher level of ambition than just the legal requirements and other criteria that need to be taken into account. Therefore, for the aspects taken into account, minimum requirements for objectives are the legal requirements that exist and the Swedish Transport Administration's own objectives and policies

Severe accidents and high costs associated with weather-related events already occur in today’s climate. Unless preventive measures are taken, the costs are expected to increase in future due to ongoing climate change. However, the risk reduction measures are costly as well and may result in unwanted impacts. Therefore, it is important to identify, assess and prioritize which measures are necessary to undertake, as well as where and when these are to be undertaken. To be able to make such evaluations, robust (scientifically based), transparent and systematic assessments and valuations are required. This article describes a framework to assess the cause-and-effect relationships and how to estimate the costs and benefits as a basis to assess and prioritize measures for climate adaptation of roads and railways. The framework includes hazard identification, risk analysis and risk assessment, identification, monetary and non-monetary evaluation of possible risk reduction measures and a step regarding distribution-, goal-and sensitivity analyses. The results from applying the framework shall be used to prioritize among potential risk reduction measures as well as when to undertake them.

Sunra (Sustainability: National Road Administration) is a decision support tool developed to be used in road projects by setting the level of ambition for different sustainability aspects and following up the work towards these in a structured way. 

This memo describes the results of continued development of Sunra adapted for local and regional infrastructure. The result is the prototypes Sulri (Sustainability Local and Regional Infrastructure) and Sulri-frequent. Sulri-frequent is intended to be used for more frequent projects, such as paving existing streets, and Sulri is intended for projects that are a little more complex such as rethinking or replanning such as improving for active travel, climate adaptation of an area or adapting a street, a place or an area to other needs, but Sulri can in principle also be used for more frequent or smaller projects. This report describes a first version of Sulri. The report shows how the tool should be used. Chapter 3 then presents the themes and aspects that are considered within Sulri. Appendix 2 gives the corresponding information for Sulri-frequent. Appendix 1 presents relevant documents and links for the different themes and aspects considered in Sulri.

This report presents the results of a feasibility study aimed at developing a methodology to support the transport Agency's planning of climate adaptation measures. The report focuses on the effect relationships for the identification, assessment and prioritization of measures for climate adaptation of roads and railways. The results presented in this report are based on literature studies and interviews with road and rail experts.

The report takes into account the consequences and risks that are expected to arise from climate-related events, such as the impact that arises from a heavy rainfall and measures that can be taken to reduce the risk and the effect thereof. Knowledge of the likelihood of a particular climate-related event occurring during a given period, as well as the size and type of injury, is required to assess or calculate the risk. The cost of damages is for example the delay costs, and costs of transfer and changes between modes of transport, etc., and recovery costs and injuries to humans.

The Swedish National Road and Transport Research Institute (VTI) has been commissioned by the Swedish Government to “contribute to the creation of knowledge regarding a rapid, smart and socioeconomically efficient electrification of the transport sector”. This report presents the part of the commission that describes a general analysis of the interaction between the energy system and the transport system, what obstacles there are and what solutions can contribute to increased electrification of transport. This part of the assignment includes good examples from other countries. 

Transport and energy have always been closely linked sectors. What is changing now, is not only the connection between the sectors, but also their nature; while the transport sector has historically mainly consumed oil products, global climate measures will drive the transport sector towards a stronger link to electricity. Therefore, the transition from oil-based transport to electricity-based transport is as much about sector changing within the energy sector as between energy and transport sectors. To handle this transition requires a conversion of both systems. The report describes the implications of the transport sector’s change on the energy system and the roles of various actors in the change. In addition, good examples from four other countries – China, the USA, Norway and the Netherlands – are highlighted. When transitioning, there are some policy aspects that are important to take into account, such as technology and behavior change, changes in the sectors and overlapping political goals.

The project examines how children’s age affects their ability to be attentive in traffic when cycling or walking to school. The data material consists of answers to a questionnaire about school routes (432 students from 45 different schools), a semi-controlled field study where the children's behaviour on the way to school was logged (20 pedestrians, 42 cyclists), as well as an observational study in various intersections (609 pedestrians, 277 cyclists). The results indicate that the traffic environment, rather than the age of the child, influences how well the attention requirements in a situation are met. This goes hand in hand with previous research which shows that it largely depends on the traffic environment whether it is safe to be there, and that there is no general age limit for when it is appropriate to participate in traffic. Rather, the design of the environment plays a significant role in how well the attentional demands can be managed. It also turned out to be important whether the students moved in a group or by themselves and how the groups were composed both in terms of age and mode of travel. 

The results from the data collections show that infrastructure design, the direction of travel, road user types and traffic rules influence which areas are important to scan visually to ensure that the road is clear. By adding such information to a geographic information system (GIS), one can systematically investigate how changes in the infrastructure affect attention requirements for different road user types and in different situations. A first implementation has been done in the project to demonstrate the potential of a GIS tool that takes attention requirements into account. Such a tool would make it easier for planners and others who shape traffic environments so that these can be designed in a way that is and feels safe for children and young people. 

Overall, the results show that the traffic environment, rather than age and cognitive maturity, sets the framework for who can or should participate in the transport system. The notion that children are not capable of participating in traffic needs to be nuanced.

Recently, Europe is experiencing more frequent and greater floods compared to the last 500 years due to climate change among other factors. This has increased the associated risks, especially in urban areas, which poses a great challenge to all stakeholders. To protect traffic networks from possible floods, this paper uses QGIS, remote sensing data, and HEC-HMS model to assess flooding events and possible adaptation measures. Two case studies have been taken; 1) a 60-mm rainstorm that occurred in 2012 on a main road in the Northern part of Sweden (NB)); and 2) a 35-mm rainstorm that occurred in 2019 in the Southern part of Gothenburg (GO). The resulting flood hydrographs show that the peak reached are 0.5 m3/s and 3.8 m3/s in GO and NB, respectively. To adapt to these flood events, four adaptation measures were assessed namely afforestation, permeable pavements & green roofs, multi-use detention basins and culvert installation considering food production, biodiversity, prosperity, and the environment. The study has shown that afforestation is an effective flood risk mitigation measure to handle both moderate and extreme rain events. Well-maintained permeable surfaces and green roofs are effective in reducing flooding due to moderate rainfall, but not in reducing the impacts of extreme rainfall events. Well-designed multi-functional detention basins are good flood protection measures, however, if they are not well-maintained, their efficiency may be reduced by up to 90 %. Culverts are effective for frequent and limited rain events but extreme rain events may even increase flood risk and thereby contribute to damaging the infrastructure.

Digital information from cyclists, bicycles, helmets, GPS and training watches etc. is already available to a large extent in society today. This information is mainly used by the cyclists themselves to, for example, follow up their or others' results on a certain distance. Additionally, municipalities perform bicycle counts, which are more generally being managed using wires, or cameras that digitally report results in real time on the municipalities' web-based maps. How could all the information that is already collected in different ways today also be used in research and operation and maintenance of cycle paths to create safer and more secure cycling that at the same time provides conditions for more people to be able and willing to use the bicycle as a means of transport? 

This study has been conducted as part of the framework for strategic projects within the Swedish Cycling Research Centre (Cykelcentrum), with the aim of reviewing the type of digital information available in society today, how data collection takes place and can be done with digital collection methods and how such measurements could complement traditional bicycle measurements. A large part has also been to investigate existing possibilities for analyzing and visualizing the large amounts of data that this generates, by for example using Geographical Information Systems (GIS) and artificial intelligence (AI). Within the research community it would be valuable to collect data in one commonly shared space and to be able to visualize their data. Different types of visualization possibilities such as platforms, maps and interactive dashboards are therefore described.

Life Cycle Assessment (LCA) studies are often used for assessing environmental effects that e.g. certain types of infrastructure investments might have during their lifetime. In Sweden the development of electric roads has reached a level where a full-scale implementation is assumed during the coming decade. The goal is to find solutions for fossil free transportation and electric roads is an important part of this. Three different concepts of electrified roads are currently discussed in Sweden; the overhead catenary, the rail in the road surface and the inductive transfer from beneath the road surface.

Since electric road is such a new type of concept there are very few LCA-studies focusing on this type of infrastructure, and only one of the reviewed studies were comparing between all three concepts of electric roads.

The lifecycle of the road consists of the building and construction of the road, the maintenance and operations, the user phase and the end of life of the road. Electric roads are planned to be installed in already existing road infrastructure, hence different kind of electric road concepts will affect the roads in different ways depending on if the technique is to be buried, surface flush, or in the side area of the road.

Different concept will also need different types of maintenance and operations. LCA studies on the environmental effects of roads show that the largest emissions of CO2 come from the maintenance and operations part of the road’s lifetime, if not considering the user phase. It will hence be crucial to investigate how maintenance will be affected by different types of electric road concepts.

Comparative LCA studies show that there is little difference between the environmental impact during the installation phase between roads and railroads. An installation of electric roads in an existing road is, however, an additional component in the environmental footprint of the road compared to the railroad, since additional technique will be installed in the road or roadside area. Meaning that an electric road will have a larger impact on the environment than a regular road during the installation phase. During the lifetime of the road this investment will, however, be paid back during the user phase of the road. Some of the LCA studies does, however, show that it will, depending on type of electric road concept, take several decades to pay back the investments of such a system. They also warn about investing in such a concept before all aspects are completely explored, as there is a risk that other techniques such as fast chargers will catch-up, making expensive road installations unnecessary.

The LCA study that compared between different concepts of electric roads has also included the reduced amout of asphalt that is needed for the road installed technologies. There are, however, some assumptions regarding maintenance and operations, made in the study that could be questioned. The few studies that are specifically investigating LCA on different kinds of electric road concepts, show that there is a lack of information and knowledge that is needed to be able to make viable assessments. These studies have furthermore not included the new types of technologies that are currently being installed during the two new demonstration projects for electrified roads in Sweden. One, in which the rail is placed on top of the asphalt minimizing the impact of the road construction by not needing to excavate the road surface, and the other one which is a new more flexible type of inductive technology, which also might reduce the impact of the road construction.

The Swedish National Road and Transport Research Institute (VTI) has been commissioned by the Swedish Government to “contribute to the creation of knowledge regarding a fast, smart and socioeconomically efficient electrification of the transport sector”. This report presents the part of the commission that describes how digitalization, including the importance of European Data Spaces, connectivity, and innovative solutions, can further accelerate and streamline electrification in the field of transport. 

The electrified transport system can be described as an interconnection of three infrastructures, where the digital infrastructure interconnects the transport and energy infrastructures, via connectivity. In addition, there is a fourth infrastructure, the legal infrastructure, that sets the legal conditions for data sharing. 

Dialogues and discussions have been held with various actors within government and municipality with knowledge in transport, energy and digital infrastructure as well as with the trade and industry, to understand the barriers that exist for accelerating the electrification of transports. 

Most of the consulted actors have pointed out similar difficulties regarding electrification of transport, such as uncertainties linked to investments and time for charging. Collaboration between different actors is required, which in turn mainly concerns data sharing. Digital information across sector boundaries is a prerequisite for creating innovative solutions that can contribute to creating added value for electrified transport, but sharing data is a major barrier. The lack of digital and technical competence and resources as well as concerns about IT security and liability issues are some of the barriers that exist for sharing data. Legal frameworks, and standardized ways of data sharing will therefore be an important piece of the puzzle. The report also describes the European Data Spaces, which are potential enablers for data sharing as they are cross-border both between sectors and EU borders and include large digital systems as well as the involvement of many actors.

Snow removal and anti-slip measures on roads are necessary to maintain road safety and a free-flowing transportation system. This is also interesting from an energy perspective as a free-flowing transportation system will use less energy than a congested one. These road maintenance measures focus, however, only on safety and not on energy use at all. This study will try to quantify the need for winter road maintenance in terms of energy in order to determine when, from an energy perspective, it would be best to remove snow or apply anti-icing agents. To explore this, parts of the VTI (Swedish National Road and Transport Research Institute) winter model were used. Several scenarios were set in different areas in Sweden in order to investigate a geographical divergence. It is possible to reduce 10.7% of traffic energy use if the starting criterion for snow removal is changed from 1 cm to 2 cm before action needs to be taken. If the speed limit is also reduced from 90 km/h to 70 km/h, the saving could be up to 17.2%. This paper aims to focus on the energy perspective of the winter maintenance operations in Sweden as well as on proposing other aspects of use for the model.

The Swedish Government decided in 2017 to investigate different possibilities and challenges with implementing electrified roads in Sweden and since then, the Swedish Transport Administration has a program for investigations and research regarding electric road systems (ERS). The Research and Innovation Platform for Electrified Roads is part of this program and the present report is a compilation of the results derived regarding environmental impact of ERS from the work in work package two of this platform.

The general concept of ERS is to deliver energy for charging and propulsion of vehicles while driving.The environmental aspects that are covered in this report are mainly focusing on particles, noise and electromagnetic field emissions. The information is attained from literature reviews and discussions with project leaders of demonstration projects for electrified roads in Sweden. Comparisons were made with similar existing techniques or concepts. The overall results indicate that more research is needed on environmental impact of ERS, mainly regarding particles from the wear of conductive ERSas well as on emissions of electromagnetic fields. It is for instance important to consider emissions from electromagnetic fields as early on in the development phase as possible as well as looking intothe standards that regulates or need to regulate these technologies in order for them to work properly together with other electrical devices on or close to the roads. Screening of electromagnetic fields is an alternative, which could become a costly solution if considered later on in the process.

Water can impact the road in different ways both directly and indirectly. A well-drained structure is usually not affected by increased water volumes, but if water enters the road structure and remains there, it can, in combination with traffic loading, cause damage and deformation. Precipitation patterns will change with climate change. It may be drier in some places and wetter in others. Longer periods of heavy rainfall may become more common during some periods of the year, while other parts may be more affected by heavy rainfall. Road structures that already have problems with moisture and water penetration can be particularly vulnerable. It is becoming more important to have an overall view of which road sections that are particularly vulnerable, to be able to prioritize which parts of a road that are most in need of quick maintenance actions. 

This study highlights the possibility of using non-destructive ground penetrating radar (GPR) to detect variations in moisture along a road stretch. The purpose was to further investigate the possibilities of using GPR as a method for detecting moisture in the road, where the main purpose was to be able to perform the measurements by car at traffic speed. There are several different methods of GPR that can be used to detect moisture, but in this study, we chose to focus on the speed of the radar wave. 

However, the study showed that the analysis work is very time-consuming, which means that this method, as it is performed in this study, is not applicable as a method to be able to quickly measure longer distances with moisture-related problems. However, there is great potential for using GPR in combination with other road measurement methods such as road surface measurements and falling weight deflectometer to locate moisture-damaged road sections.

The aim of this study was to evaluate the consistency between ocular inspection and physical measurement of dry road marking retroreflectivity. Such subjective inspection is the basis for decision of maintenance of road markings, but is it good enough?

In order to get an objective measure on the performance of the road marking a mobile equipment called RMT has been used at the same time as the ocular revision. The measurements were made without the entrepreneurs’ knowledge. All measurements were carried out in three regions in Central Sweden. The subjective and objective measurements were compared with information from the Road Administration data base on road markings called LINA. Only parts of the roads where data from both ocular inspection and physical measurement were included in the analysis.

The Swedish Transport Administration is investigating different aspects that can help contribute to the transition towards fossil free transportation. Electric Road Systems (ERS) is one of many interesting concepts that are currently being considered. The aim in this report was to examine the various electrified road concepts through literature reviews, discussions with experts and electric road developers, and visits to the electrified road demonstration projects in Sweden. Analyses were made with regards to how the construction, maintenance, and operations could be affected by the installation of an ERS. Consideration was also given to the impact on road sustainability from other types of installations currently found in the road structure, such as tramways or electric wiring. Focus was directed on installation procedures and the contracts that regulate current road maintenance and operations.

There are large differences between the various ERS concepts. The three main concepts investigated were electric transfer by overhead catenary cables, conductive transfer from a rail on or in the roadstructure, and the inductive technology which is completely embedded within the road structure. The various concepts all have advantages and disadvantages. For example, the catenary concept will not affect the road surface, whereas the rail and inductive technologies will affect the road structure during the installation procedure and the roads service life. However, the catenary concept will influence maintenance operations by complicating verge maintenance and snow ploughing activities. The embedded inductive technology will probably not affect winter operations; however, the rail concepts will affect winter operations by the need for different types of snow ploughing activities.

In 2020, the Swedish Transport Administration received a governmental assignment to analyze the conditions and plan for the expansion of electric roads. In the assignment, an analysis was made regarding a potential degree of utilization of electric roads in Sweden, based, among other things, on the development of heavy electrified road transport. 

The degree of utilization is a central factor in being able to understand the consequences, for example in terms of environmental benefits and socio-economic profitability, that the establishment of electric roads can entail. The utilization rate in the Swedish Transport Administration’s report was estimated at 25% in the event of a full expansion of the electric road network by the year 2040. Due to external developments and the rapid technological development in the electric road market, other European countries have made similar investigations which resulted in other utilization rates. Therefore, there was reason to renew the analysis of the potential degree of utilization of electric road system in Sweden. 

To be able to determine whether the utilization rates produced in the Swedish investigation still stood, a comparison was made between these calculations and the reports of four other European countries, Germany, France, Great Britain and the Netherlands. The aim was to analyze the importance and influence of various factors on the degree of utilization of electric roads. The goal was to present a method to be able to make comparisons regarding included factors as well as calculations of the degree of utilization based on selected factors. 

This report proposes different approaches for estimating utilization rate, by exemplifying different estimates based on different input factors and calculation basis. The report also includes a sensitivity analysis to demonstrate how different assumptions can produce different utilization rate results. 

The investigation shows that detailed information from several sources is required to be able to make reliable estimates about the utilization rate of electric roads. Based on the sensitivity analysis carried out, it becomes clear that Swedish long-distance transport accounts for the single greatest use of the electric road. It will therefore be important to examine which behaviors in the vehicle fleet that are required to switch to electric road operation, as these factors are decisive for the utilization rate.

The government has commissioned the Swedish National Road and Transport Research Institute (VTI) to “contribute to the building of knowledge around a fast, smart and economically efficient electrification of the transport sector”. This report focusses on the part of the mission that deals with conducting pilot projects and developing models for how data, in practice, can be made available, shared and utilized in the best way to optimize planning, development, operation for charging infrastructure and business models. 

The report provides a description of existing technologies for charging electric vehicles, important user perspectives, and how business models and systems for charging infrastructure can be modelled. 

The report focuses on data sharing and describes how actors today share data and what difficulties they see with data sharing. This includes, among other things, data availability, sharing and utilization, as well as how the actors want it to work going forward. A major challenge concerns data availability, where actors partly see problems with getting access to data and partly are hesitant to want to share their own data. Often, it is about privacy issues and regulation according to the GDPR. 

The importance of a well-functioning collaboration between the energy and transport sectors has been highlighted in previous reports from this assignment. 

The importance of digitalization and digital infrastructure that connects these sectors is particularly emphasized in this work. Digitalization is needed to streamline planning, development and operation of the infrastructure that an electrified transport system requires. The modeling done in this part of the assignment deals with transport modeling and energy modeling as well as development to make the models interact.

This study assesses the potential for decarbonizing EU road transport through several pathways, focusing on the feasibility of achieving impact by 2035. Through comprehensive literature review, we compare the distance-levelized cost, lifecycle GHG emissions, and scalability of combustion engine vehicles (three fuels), battery-electric vehicles (BEVs, three charging methods), and hydrogen fuel cell vehicles. We consider projected transport growth and the current age composition and use of vehicles in Europe, segmented into four regions. Biofuels, hydrogen, and e-fuels are not found to have potential to significantly contribute to further GHG emissions before 2035 due to scalability and technological limitations. BEVs emerge as the only viable strategy for achieving zero tailpipe emissions at scale, with effective lifecycle GHG reductions constrained by the rate of decarbonization of steel production, battery production and EU electricity production. By 2035, embodied battery emissions are expected to be the dominant source of lifecycle emissions from electric vehicles.

The environmental benefits of a BEV transition are primarily limited by the rate at which the vehicle stock can be electrified, with new electric vehicle sales contributing primarily to decarbonization in Northen and Western Europe. Combining the expected buildout of static charging infrastructure with a proposed pan-European Electric Road System (ERS) network is found to greatly accelerate the transition to electrified road transport, including in otherwise late-to-decarbonize segments, by removing cost, weight, and supply barriers to retrofitting older combustion engine cars with new electric powertrains. Other effects of an ERS network are found to be substantially reduced embodied emissions from BEV production, resulting from reduced battery capacity per vehicle, and reduced levelized freight costs. However, possibly insurmountable political and bureaucratic barriers must be overcome ERS to play any meaningful part in decarbonization of road transport within the coming decade. If the barriers can be overcome, the economic and ecological rewards are substantial.
