Abstract
The term "road transport informatics" (RTI) is currently used in Europe to describe a broad range of information technologies and systems which can be used for various applications in the field of highway transportation. This paper describes progress on a major European study into the use of road transport informatics in implementing demand management policies. The study described involves investiga- tion of the application of various RTI technologies to demand management measures such as road pricing, restrictive zoning and access control.
