Abstract

This diploma thesis presents the behavior of program, which uses the traffic light enhanced transport network to simulate the traffic flow of vehicles that behave according to the IDM model. We upgraded the program to allow, for the given network, to optimize the traffic flow. Because of the overwhelming problem of road closures or their rearrangement, we added a graphical user interface with which a user can create or modify the road network to observe changes in traffic. The objective of this diploma thesis is to create a simulator with which it will be possible to construct a traffic lights road network. Using this network, it will be able to optimize the time intervals of traffic lights to improve traffic flow. The main part of this diploma thesis is to prepare a program for the composition of road links, where cars and other vehicles drive through. In addition, traffic lights at junctions are changing at different time intervals. The program has to be adapted to allow parallel execution of multiple simulators with different traffic light interval settings. The aim is to find the optimal settings of the intervals of traffic lights, the result being the most effective traffic flow.
