Abstract

The Highways Agency Traffic Information System (HATRIS) holds journey times and traffic flows for each link of the network of motorways and major "A" roads in England managed by the Highways Agency. The data is held for every 15-minutes of the year and is obtained by combining data of three different types - inductive loops, automatic number plate recognition cameras, and GPS tracked vehicles. This paper describes the different sources of data in more detail, how the data is collected and processed, and how it is used to support performance management and to provide information to road users. For the covering abstract see ITRD E134653.
