Fuzzy logic system for variable message signs in Kuala Lumpur

Abstract

Intelligent Transportation Systems refer to a wide variety of advanced and emerging technology applications designed mainly to reduce traffic congestion and emissions, and to improve highway efficiency, safety, and convenience. Variable message signs (VMS) is one of the dynamic route guidance tools which are increasingly used in the transportation sector to give information in order to improve and make the journey more efficient and safe. Saving motorists travel time is most important parameter which should be mentioned. Fuzzy control has proven to be successful in problems where exact mathematical modelling is hard or impossible but an experienced human operator can control process. This study attempts to simulate and design a fuzzy logic controller with archived traffic data for VMS in Kuala Lumpur to optimize the system performance and understand how the system is going to behave for the entire range of values in the input space.
