Due to the rapid growth of the number of electric vehicles in Austria in recent years, the topic of electric mobility is becoming increasingly important. In addition to its indisputable advantages, this development bears a number of challenges. Each of it requires appropriate solutions. One of the biggest challenges in this context is the existence of a suitable charging infrastructure. How this optimal spatial distribution of the charging stations in the long-distance transport network of Austria has to look is the issue of this diploma thesis. In addition to the study of the state-of-the-art and the current percentage of electric vehicles, various scenarios are analyzed. These should represent the future of electric mobility. For this purpose, a suitable optimization model will be developed in Matlab. That will calculate the optimum number and location of charging stations and charging columns based on the Austrian motorways and expressway network and the associated traffic flow data. Then the calculated distribution is graphically plotted using QGIS to evaluate the spatial distribution. All rest points of the long-distance network are used as possible locations, because the necessary infrastructure for parking and power supply is already given there. In addition to finding the optimum spatial distribution of the charging stations, the optimizing model calculates the greatest possible profit for the charging infrastructure operator. The results of the individual scenarios of the diploma thesis show, that the technology of the charging stations and batteries of the electric vehicles has to develop very strongly, because otherwise the energy requirement for a completely electrified traffic can not be achieved. One reason for this is for example, that with the current state of the art the number of parking spaces would be much too high, which would require the large number of charging stations. However, the current research and development, as presented in the literature, points exactly in the right direction for more electric mobility in Austria's long-distance network. This direction is given on the one hand by higher charging power and the associated shorter charging time and on the other hand by larger battery capacity of electric vehicles and thereby higher ranges. As this diploma thesis will show, the increasing electrification of long-distance transport results in an extremely high saving potential of greenhouse gas emissions from the ecological point of view. On the other hand, this is a very big challenge for the financial budget of Austria, as it eliminates a very large amount of tax due to the current petroleum tax and motor-related insurance tax for combustion engine vehicles.
