Abstract
The services provided by the Highways Agency's National Traffic Control Centre are key to satisfying the objectives of providing better informationto travellers and ensuring more reliable journeys. This paper describes the context within which the control centre has been delivered; the means by which it collects data on conditions on England's motorway and all-purpose trunk road network; how that data is analysed; and the means by which information is disseminated to the general public. These services are providing the catalyst for the development of traffic information delivery tools by the Agency and private sector information providers. For the coveringabstract see ITRD E134653.
