Vehicular traffic became an essential part of our daily life. We have several causes to improve the quality of vehicular traffic or transportation, such as preventing accidents, reducing pollution and traffic jams or increasing energy efficiency. Intelligent transport systems are developed to support the solutions of these problems. The topic is extremely extensive, thus I will focus on the heterogenous vehicular networks. It is quite difficult to research it in practical manner without setting up various models and simulations based on these models. Fortunately these systems are already established and I will use one of these.
My aim is to build up and make a simulation in a framework called VeinsLTE, which is based on OMNeT++. To achieve this at first I will describe the theoretical background. I will show the architecture, the building blocks and the operation of Intelligent Transport Systems. I will also present the most important applications and services based on these systems. Furthermore I will present a novel researched area of ITS called Heterogeneous Vehicular Systems. Finally I will make the simulation and the measurements on this simulation, and will summarise the conclusions.
