Abstract

Reports our experiences with agent-based architectures for intelligent traffic management. We describe and compare TRYS and TRYSA/sub 2/, two multi-agent systems that perform decision support for real-time traffic management in the urban motorway network around Barcelona. Both systems draw upon similar traffic management knowledge, but the former is based on a centralised architecture, while in the latter, co-ordination emerges upon the lateral interaction of autonomous traffic management agents. We conclude that the centralised approach applied by TRYS promotes efficiency for real-time operation, whereas the decentralised approach used in TRYSA/sub 2/ promotes scalability.
