oa Civil Engineering = Siviele Ingenieurswese - Real-time traffic speeds on South African roads : the technology, applications and possibilities



The advent of commercial GPS technology and the inexpensive wireless transfer of bulk data via GPRS, coupled with a large installed base of vehicles tracked for security / recovery purposes, have facilitated anonymous real-time traffic speed monitoring on the country's roads. In this article the underlying technologies are explained and the development of a system which graphically displays average speeds and current journey times is described. Other applications, actual and potential, are also discussed.
