A hierarchical system for optimising a dynamic system of traffic crossroads control using an expert system

Abstract

Nowadays in the field of the automotive industry and urban public transport, there are a lot of challenges and problems to solve. Every day there are closures, roadworks, and other aspects of public transport, which cause traffic jams. This paper deals with a hierarchical system for optimising a dynamic system of traffic crossroads control using an expert system. The hierarchical system uses an expert system constructed in a few layers which evaluate the length of the green signal for each phase of the crossroad. The main goal of the proposed system is traffic optimisation at crossroads and reduction of traffic jams. The proposed system was verified on a real crossroad in the city of Ostrava.
