**Abstract:**

This paper presents a fuzzy multi-agent system for control of the
traffic signals of an urban network, where the aim is to reduce the
total average delay time of the vehicles. The large-scale traffic
system is first divided into sub-areas and an agent, using a fuzzy
controller, is considered for each sub-area. In order to develop the
fuzzy rule bases for the agents, an extensive set of data is collected
and the corresponding origin-destination (OD) matrices are calculated.
The OD matrices are then clustered using a new clustering algorithm
proposed in this paper. Finally, the resulting cluster centers, which
are matrices of the same dimension as the OD matrices, are mapped to a
2-dimensional space and the corresponding triangular fuzzy sets are
extracted. An optimal cycle plan is found for each fuzzy set and this
way the fuzzy rule bases are constructed (the triangular fuzzy sets
form the IF-parts and the optimal cycle plans form the THEN-parts). In
a case study the proposed multi-agent control system is applied to a
microscopic urban traffic network and the results are compared with a
controller that applies optimal signal plans calculated by PASSER V.
The results show that the proposed fuzzy multi-agent system
outperforms the non-fuzzy control system, where the average delay time
of the traveling vehicles is decreased by 19% using the multi-agent
control system.
