Organic Traffic Control

Contact: Hartmut Schmeck

Project Status: completed


It is the goal of the Organic Computing initiative to investigate emergent and self-organizing phenomena and their practical usability in technical systems. Such a technical system is characterized by a large population of relatively autonomous agents, acting and learning predominantly in their local context with some limited sensory horizon, and the co-operation of these agents to solve a global problem. Traffic control is a promising field to apply this technique. Within the project Organic Traffic Control (OTC) we will use a network of adaptive learning traffic light controllers to study the possibilities and limitations of organic decentralized control systems. The project will follow two complementary approaches to the learning problem with the goal to combine both in one system: Online learning controllers will adapt their behaviour based on Learning Classifier Systems receiving direct feedback from the environment. Simulation-based offline optimization will try to find optimal control parameters by using evolutionary algorithms within a simulated environment focussing on the design of robust solutions. A combination of both ideas will use offline optimization to coarsely search the parameter space while online learning will be responsible for local fine-tuning. Both approaches will be implemented and compared using a simulated city environment.
