Abstract

The task of this thesis is the simulation of urban traffic.

For this purpose the traffic library TrafLib was developed. TrafLib is a multi-agent, micro simulation for urban traffic. It is suitable for visualisation, e.g. urban visualisation software, driving simulators, computer games, virtual reality software, and so on. It enhances them and makes them more attractive.

TrafLib requires a road-network in the form of an input file. The input file must contain the description of roads and crossings, and optionally traffic lights and traffic signs. Additionally to the own file description format, the format of VRMG is also supported. VRMG is a program for creating geometry of large road-networks.

The problem of traffic calculation is solved by handling traffic rules according to the Highway Code and the “Car-Following-Theory”. The vehicles are modelled as autonomous agents. Human characteristics are imitated by three different types of driving-behaviour (cautious, normal, aggressive).

The movement of the vehicles takes place on 1-dimensional lanes. This reduces the flexibility a little, but simplifies the calculation a lot.

TrafLib is able to simulate more than 5000 vehicles on a road network of the size of 3 times 3 km in real-time on a standard-PC.
