DESIGN OF OPEN TRAFFIC INFORMATION SYSTEM FOR GENERATING & DISSEMINATING TRAFFIC INFORMATION THROUGH MOBILE MESSAGING

Abstract

With increasing number of vehicles on roads, traffic congestion has become routine and is causing immense physical, economic and environmental losses. This thesis proposes a novel Open Traffic Information System (OTIS) in which the traffic information is not only received by the mobile phone users but is also generated by them. The users of the system work ‘for the system’ and in return gain ‘from the system’. The proposed system is open in the sense that any person with access to mobile phone may generate traffic information and receive traffic updates through mobile messages. All existing traffic information systems either require significant investments in new infrastructure or depend on third party sources to generate traffic information whereas the proposed system could be instantaneously deployed over the existing cellular network. The thesis develops the system using two approaches namely, Data Flow Diagram and Petri Nets, and then presents a working model of the system.
