    Den svenska förarutbildningen: dagsläge och framtidsutsikter2017Report (Other academic)
    Abstract [en]

    The overall aim of this study is to provide a deep and broad understanding of current practice of driver training. Based on the results of four in-depth studies, the project attempts to identify the need for improvement. Furthermore, and in order to improve driver training some essential actions will be presented. Several methods have been used to achieve this aim. The report starts with a literature review looking at various aspects which can influence young driver trainer’s ability to drive safely but also literature looking at deficiencies and needs for change. The following chapter presents accident statistics which includes current data on young drivers’ accident involvement and how this has changed in recent years. That is followed by a summary of statistics on driving license tests and retests. The project also includes an interview study in which eleven professionals were interviewed (politicians, government officials, researchers and representatives of driving schools and race tracks). The purpose of this study was to discuss their views on the current driver training in Sweden but also their own suggestions for change. Two surveys were then carried out. The first was aimed at new drivers of different ages about their driver training and the other was aimed at driving instructors. The general conclusion of this study is that the general discussion of driver training focuses too much on time and cost rather than quality which does not favour traffic safety. The recommendation is therefore that there is a need for a more fundamental change of driver training. To realise this, some of the teaching methods used need to be improved. These methods can then be applied to “risk education” and to the more general driver training. Other areas which are in need for improvement focus on; private practice and a closer contact with driving schools, enhancing the quality of compulsory training and introduce more parts, more frequent quality assurance of driving schools and increased supervision and collaboration between stakeholders, a development of driving licence testing and a better consensus between the objectives, content/process and driving test, a clearer division of responsibilities regarding research and development and a better coordination of the various elements of driver training. Finally, there is a need to highlight best practice which can only be done if evaluation becomes common practice.

    Vehicle driver monitoring: sleepiness and cognitive load2017Report (Other academic)
    Abstract [en]

    To prevent road crashes, it is important to understand driver related contributing factors. The overall aim of the Vehicle Driver Monitoring project was to advance the understanding of two such factors; sleepiness and cognitive distraction. The project aimed at finding methods to measure the two states, with focus on physiological measures, and to study their effect on driver behaviour. The data collection was done in several laboratory and driving simulator experiments. Much new knowledge and insights were gained in the project. Significant effects of cognitive load as well as of sleepiness were found in several physiological measures. The results also showed that context, including individual and environmental factors, has a great impact on driver behaviours, measures and driver experiences.

    A Simulation Model of Local Public Transport Access at a Railway Station2017In: / [ed] N. Tomii, I.A. Hansen, J. Rodriguez, P. Pellegrini, S. Dauzère-Pérès, D. De Almeida, 2017, 922-943 p.Conference paper (Other academic)
    Abstract [en]

    A high quality railway service requires that all parts of the complete journey, from door to door, are well-functioning. This includes any transfers taking place, as well as last mile transportation to and from the railway station. Since the last mile often consists of local public transport, the access to this mode at stops and terminals and how well these are functioning are of great importance. A critical aspect is the capacity of the stop or the terminal in relation to the number of departures, where a higher capacity generally means an increase in size. At the same time it is desirable to limit the use of valuable land and keeping the facility as small as possible. The trade-off between capacity and size needs to be evaluated when designing stops and terminals. In this study we have developed a discrete event simulation model of a combined bus and tram stop, which is a part of a larger multi-modal station. The objective of the study is to evaluate the modelling approach for the situation at hand. Of special interest are the complexities due to the different driving patterns of buses and trams. The developed model is capable of evaluating design alternatives and is applied in a case study of a stop at Norrköping railway station in southern Sweden. The model was found to realistically capture the various events occurring at such a stop and the case study further showed that the model is a useful tool in design evaluation.

    Framtidsscenarier för självkörande fordon på väg: Samhällseffekter 2030 med utblick mot 20502017Report (Other academic)
    Abstract [en]

    The development in the field of self-driving vehicles is quick and many vehicle manufacturers (GM, Ford, Toyota, BMW, Audi, VW and others) say they will launch a fully self-driving vehicle on the market around 2020. Although technology development will move quickly in the coming years, big questions remain regarding; how self-driving vehicles will be received by society, where they will be allowed, if they will be used primarily as private or shared vehicles, how they will handle traffic safety, privacy and cyber-security issues, and to what extent they will influence accepted commuting time, mode choice and induced travel by car.

    At the same time, long-term socio-economic effects are not primarily determined by technological advances, but mostly by the role self-driving vehicles will have in our society, that is, their effects on traffic and urban planning in general. Therefore, it is important to sketch possible future scenarios for self-driving vehicles. Based on these scenarios, a discussion can follow on how regulations and policy instruments should be used in order to maximise social benefits of self-driving vehicles.

    This report describes the work with future scenarios for self-driving vehicles undertaken during the winter of 2016/2017. An analysis group consisting of five people, supported by a passenger transport expert group that met for three full-day workshops, identified both a secure development towards 2030and two uncertain axes that lead to four possible scenarios for the future with self-driving vehicles in Sweden. With participation of 40 experts from 23 transport organizations, this study is unique compared to previous scenario work concerning the development of self-driving vehicles which have been based either on literature studies or expert workshops with few researchers.

    Hållbara turistresor: en fallstudie av destinationerna Kiruna, Åre, Sälen och Vimmerby2017Report (Other academic)
    Abstract [en]

    In conjunction with development of destinations and transport systems, tourist demands and requirements are essential in determining measures and changes that may lead to more sustainable travel. Different options for travel to and from destinations are of great importance, but also the geographical accessibility to various visit points within destinations. Good accessibility within a destination without a private car may also influence the modal choice for the trip to and from the destination.

    This study analysed the requirements of different categories of tourists for transport, their travel patterns and their preferences regarding travel to, from and within four Swedish destinations: Kiruna, Åre, Sälen and Vimmerby. The aim was to develop knowledge about factors that may affect the sustainability of tourist travel. The empirical material for the analysis was collected through questionnaires distributed to visitors on-site in the destinations.

    Hastigheter på kommunala gator i tätort: resultat från mätningar 20162017Report (Other academic)
    Abstract [en]

    The aim of the present study is to report the changes between the years 2015 and 2016 concerning driver speed levels and speed limit compliance on the main municipality streets. The year 2012 was the starting year for the measurement series, and in 2016 a fourth follow-up was performed. Only the main municipality streets with speed limits between 40 km/h and 70 km/h were included. The measurements were made during the month of September in 23 different municipalities in Sweden.

    The results show that in 2016 the space-mean-speed for all vehicles on the main municipality roads was 47 km/h. With respect to speed violations, overall, 67 per cent of drivers obeyed the speed limit 2016. The lowest speed limit compliance was found on roads with a speed limit of 40 km/h, where only 53 per cent of the traffic obeyed the speed limit; 68 per cent obeyed the speed limit on 50 km/h roads, 72 per cent on 60 km/h roads, and 78 per cent on 70 km/h roads.

    Förares användning av kommunikationsutrustning under färd: Del 1: Enkätstudie. Del 2: Användning enligt objektiv mätning2017Report (Other academic)
    Abstract [sv]

    Av resultaten från denna enkät är något av det mest tydliga att saker som funnits i en bil en längre tid, exempelvis att ställa in radio, använda navigationsutrustning och prata i telefon, görs i betydligt högre utsträckning än nyare saker som att skicka meddelanden, surfa på internet eller spela spel. Överlag tycks det vara låg acceptans för de nyare företeelserna och en stor andel av urvalet tycker att det är felaktigt eller olämpligt att hålla på med dessa aktiviteter. Att prata i telefon med handsfree tycks uppfattas av många som säkrare och mer lämpligt än att inte använda det. Detta avspeglas även i inställning till införandet av förbud, där en relativt stor andel accepterar att det ska vara lagligt att använda handsfreefunktioner men att annan användning av kommunikationsutrustning borde förbjudas.

    I den andra delen genomfördes en mätning av mobilanvändning under färd genom installerande tav en mobilapp. Den genomförda undersökningen är den första av sitt slag åtminstone i Sverige, så att den, trots vissa brister och begränsningar, kan leverera information som hittills har varit okänt. I detta del diskuteras resultaten, även i förhållande till enkätsvaren, följt av en reflektion över metoden och möjliga förbättringar, som är önskvärda inför en fortsättningsstudie.

    Behov av statistik om godstågens tillförlitlighet: en förstudie2017Report (Other academic)
    Abstract [en]

    At present, the official statistics on rail traffic in Sweden only comprise passenger trains. The reliability of freight trains should also be included in the statistics. This leads to questions on which information should be included and how it should be described. This pre-study is a knowledge base of the necessary development of the official statistics in Sweden, and is centered on the users’ current and potential needs of statistics on freight train reliability.

    In this context, reliability is the ability of a transport system to follow the timetable, upon which users have organized their activities. A traffic disturbance, such as delays or cancelled trains, creates unreliability in the transport system, which should be characterized in more ways than the frequency of the disturbances in order to meet different users’ needs of statistics. To produce the necessary statistics, one must answer the following questions. Which units and variables should be included? Which domains should be included? Which statistical measures should be presented?

    This study shows that the relevant units are vehicles and traffic disturbances. The necessary variables are scheduled, arrived and cancelled vehicles, as well as vehicles that are adjustments/late changes of the timetable. Variables on timetable deviations for vehicles running on the network are also necessary. In this aspect, there are differences between passenger and freight trains as the latter group relatively often depart or arrive ahead of schedule, which is also important to capture with statistics.

    Tillståndsuppföljning av observationssträckor: lägesrapport för LTPP-projektet till och med december 20162017Report (Other academic)
    Abstract [en]

    The objective of this project is to collect and deliver high quality road data primarily for use in the development of performance prediction models. Monitoring of the LTPP sections (100 m long) started in 1984 on commission of the Swedish Road Administration. The aim is primarily to focus on road deterioration caused by heavy traffic. The project started with a limited amount of sections but, in 2016, the number has increased to 690 sections distributed over 65 sites. All sections are included in Sweden’s national road network. During the year, some sections became redundant and a number of replacement sections were included. Budget restrictions in 2000 resulted in a review of the sections and a 25 percent reduction in monitoring was implemented. Despite this decrease, the project purpose could still be maintained. By retaining the most strategically important routes and reducing the number of surveys useful high quality data could still be obtained from the sections left in the monitoring program. In addition, the introduction of median barriers on some sections (to facilitate traffic separation) has meant a disqualification of suitability. During 2017, 313 sections distributed over 33 sites will remain active.

    Jämförelse av flöde och hastigheter från två olika cykelmätningsutrustningar2017Report (Other academic)
    Abstract [en]

    The purpose of this study was to compare cycle flows and speeds from two different cycle measurement equipment. The result has also been compared with the processed video data and manual counts. The measuring equipment are Viscando’s equipment OTUS3D and VTI´s TA-89. OTUS3D is a camera with 3D functionality, and it detects tracks and classifies these into different road user categories. TA-89 (where TA stands for Traffic Analyzer) is developed by VTI and is adapted for detecting both bicycles and motor vehicles. We also used a video camera from the OTUS3D system, to enable a manual calculation.

    The test site for the study is a pedestrian and bicycle path that crosses a ridge in Vallaskogen in Linköping. The area is located between the district of East Valla and campus. It is a fairly steep slope where the direction towards the campus is uphill and the direction to the East Valla / city center is downhill. Five days that did not include losses of flow were selected for the analyzes. The selected periods were 3 to 4 September (Saturday and Sunday) and 6 to 8 September (Tuesday to Thursday). In addition to this, we chose an hour with high flow and an hour with low flow where video processing was conducted. Furthermore, we used an hour and 50 minutes of manual counting.
