    Ecodriving på SJ: förarperspektiv på tekniska hjälpmedel för beslutsfattande och utbildning i Ecodriving2013Report (Other academic)
    Abstract [en]

    Even though all trips with SJ trains in Sweden are labeled “Bra Miljöval” (Good environmental choice), the requirements for reduced emissions and energy usage are constantly increased. Thus, SJ has to constantly develop their environmental profile. To investigate potential energy savings, SJ developed an education program in energy efficient driving (Eco-driving) and also let some of their train drivers use a technical tool supporting eco-driving. This report includes two studies. A critical review of the experimental study conducted by SJ and a complementary study based on observations of the education in energy efficient driving, along with interviews with the train drivers that participated in SJs experimental study. The experimental study provided valuable results, suggesting that energy savings through driver training and support are feasible. At the same time, there are contingencies in the collected energy data, making it difficult to draw any definite conclusions. The results of the interviews with the drivers show that there are ambiguities about what risks and consequences a future introduction of the technical tool for eco-driving could imply. Altogether, there are reasons to conduct further studies on how to best introduce energy-efficient driving in railway traffic as a whole.

    Lärarperspektiv på riskutbildningen för motorcyklister2011Report (Other academic)
    Abstract [en]

    Over the last decade it has become increasingly popular to ride a motorcycle in Sweden. A mandatory risk education for competence A and A1 was introduced from the 1st of November 2009. Since the education is new, few evaluations have been conducted so far.

    This study evaluates the risk education for motorcyclists based on the perspective of driving instructors. The goal was to compile the instructors' comments and experiences with respect to the new risk training. An additional objective was to examine the driving instructors' perceived effects of the education on their students' driving behavior. Six semi-structured interviews with driving instructors and an observational study of the education at various driving schools were conducted. In addition, a participant observation study was performed during a further education of 15 driving instructors. The results show that the instructors experience a great need for the new risk training and that the implementation of the training itself has been good. Students have been referring to the risk training, which according to the instructors indicate that the students have embraced the essence of the training. As a result, the students drive more carefully now and think twice in certain situations according to the instructors. This was considered a desirable result.

    Simulatorbaserad utbildning i ERTMS: utvärdering av utbildning och träning för lokförare i VTI:s tågsimulator2015Report (Other academic)
    Abstract [en]

    The purpose of this study was to evaluate the VTI train simulator with regard to simulator-based training and education in the ERTMS (European Rail Traffic Management System) system for train drivers, compared to the ERSA simulator. The purpose was also to study two different ways of combining theoretical education with practical training in a simulator. In the future, the major railway routes in Sweden will be equipped with ERTMS. This will require considerable training for Sweden’s approximately 3,500 train drivers in future need of ERTMS education. It is unrealistic to think that these should be trained on real tracks. Therefore, there is a need for a more realistic ERTMS simulator compared to the European Rail Software Applications (ERSA) simulator that Trafikverket provides. The study was conducted as a between group design with two measurements. Three different groups were compared under different conditions. Theoretical education in ERTMS combined with training in the ERSA simulator (group 0), theoretical education in ERTMS ending with training in the VTI-simulator (group 1) and theoretical education in ERTMS partly alternated with training in the VTI-simulator (group 2).

    Lokförarutbildning i Sverige: simulatoranvändning och ERTMS2014Report (Other academic)
    Abstract [en]

    This report, which provides an overview of the compulsory basic training for train drivers in Sweden, highlights the occurrence of simulator-based training in education, along with the training efforts being made with regards to the future introduction of ERTMS/ETCS. The report also shows the possibilities and limitations of increased use of simulators in driver training and describes the most important governing documents for train drivers and train driver training. Furthermore, the Swedish Transport Agency curriculum for train driver licenses is presented along with the institutions engaged in basic education, training and examination of train driver’s. Also, the Swedish Transport Administration’s E-learning tool for ERTMS, the ERSA-simulator and company specific ERTMS education at SJ and Green Cargo are described. Moreover, Swedish train companies’ and educators’ current use and future needs of simulators for train driver training were examined. Examples from other domains where simulators are used in a training context are also presented.

    Läsbarhet av vägskyltar i form av LED-skylt: färgkombination och fontstorlekens betydelse för läsbarheten2015Report (Other academic)
    Abstract [en]

    The readability of road signs was studied and in particular the LED format. The purpose of this study was to study the effect of color combination, font size and light conditions on readability. 101 students participated in the study, where 32 were men and 69 were women. Their age ranged from 18–66 years. The choice of subjects were driven by the study's purpose, i.e. for this study it was not of interest to study the differences between gender, age or eyesight. A statistical analysis was carried out to study how readability distances varied as a result of the combination of colors, font size and light conditions. Furthermore, illuminance was measured when the data collection occasions was conducted. Distances were examined both in daylight and in darkness. The results of the study show that the color combination of the LED-sign affects its readability. Signs with white text on blue, brown or green background could be read correctly at a greater distance than the signs with black text on white or orange background. The font size is also important for the readability and every increase in font size produces a significant difference in the distance that the sign can be read. The sign with the largest font size (300 mm) was read correctly from the longest distance. The signs were read even at greater distances in daylight than in darkness. The readability of the sign with the smallest font size 200 mm does not change significantly during the daylight compared to darkness conditions. These conclusive results demonstrate that all the variables studied are important for readability. It should be added that participants stood still during the trial when they scanned/read the signs and had free sight to the LED-sign.
