Verification and Prototype Implementation of Fuzzy Self-Organization Decision Algorithm for UTCS

Urban traffic control system (UTCS) is a kind of large-scale complex systems. As to such systems, it´s very important to provide functions of dynamic self-organization decision in the higher layer so that multiple control patterns and multiple control modes can be selected and utilized rightly at different locations and different moments. In this paper, an algorithm of dynamic self-organization decision for UTCS based on structural model of signal networks, which is depicted by fuzzy adjacent matrix, is presented. Moreover, balance of signal cycles is considered and used to improve the algorithmic performance and its rationality is verified from theoretical view. In addition, a prototype is implemented in VC++ 6.0 environment, tested over a typical signalized traffic network, and elementary results are summarized. Finally, conclusion is brought that it is a good choice to adopt dynamic self-organization decision based on fuzzy structural model and fuzzy algorithm in large complex control systems.
