Dynamic tra c management system via GPS and localization

Abstract

Road intersections using tra c lights are the most common form of crossways that are used throughout the world. Mostly due to space limitations how- ever cities tend to be using intersections in road networks which are rather inadequate for the number of vehicles it serves, causing high levels of con- gestions. The traditional approach to solving this is to vary the timing of the tra c signals so that roads with greater number of vehicles are allowed to pass through for a longer time. This method works in concept, however in practical applications it has always been somewhat ine ective due to the lack of data regarding the number of vehicles at the intersection. This thesis is based on creating an e ective wireless communication channel between ve- hicles and road infrastructure via a method of localization using GPS, RFID and some algorithms which have been developed to make sure that vehicles only respond to tra c signaling units and road signs which applies to said vehicle.
