Diploma Thesis, TU-Vienna, 2015

Toll systems are very important in our society. They aim at various tasks, from refinancing the construction and maintenance of road infrastructure over the reduction of congestions to the limitation of car emissions, in order to help saving our environment. Current toll charging systems, however, have some serious drawbacks and interoperability among European toll charging systems still needs to be solved satisfactorily. On the other hand, smart devices, like smart phones and tablets are owned by an increasing number of people. These devices can host mobile applications and could therefore act as an On Board Unit (OBU). This is why, in the presented thesis, a mobile application, which provides the features of current OBUs is developed for the Android platform. It implements the functionality of a location based toll charging system, with the help of virtual points, which can be used to generate bills. In order to see if this is not only possible technically, but if such an application would still remain usable, usability tests have been performed and evaluated, too. Such a system would be usable throughout Europe, easy to deploy, and easy and comfortable to use.
