Development and evaluation of a multi-agent approach to traffic signal control using traffic simulation

This thesis is aimed at demonstrating the feasibility of using recent software development techniques based on distributed agent technologies to develop a decentralised multi-agent traffic signal control system. The motivation for this work stemmed from a recognition of the limitations of existing traffic signal control methodologies and an acknowledgement that traffic control is a large-scale, complex, dynamic problem with highly nonlinear characteristics. A review of existing systems revealed a number of challenges and limitations and showed that the majority operated principally on pre-defined plans which were suitable only for pre-determined situations. As a result, they failed to control unexpected conditions when traffic flows changed rapidly. The performance of existing systems was also found to suffer during over-saturated conditions and the main challenge in this thesis was formulated as the need to shift from controlling near-saturated conditions to the requirement for traffic control during over-saturated conditions. This thesis adopted a traffic simulation approach for the evaluation of the proposed multi-agent traffic control system.
