Review of tolling and communications aspects of the US National Architecture. Prepared for the Department of the Environment, Transport and the Regions DETR, Tolled Roads and Crossing Division TRCD.

TRL has undertaken a review of tolling and Dedicated Short Range Communication (DSRC) aspects of the US National Architecture (NA) on behalf of Department of Transport (now Department of the Environment, Transport and the Regions) Tolling and Private Finance Division (TPF2). It is concluded that the NA has made specific choices in the areas of tolling and DSRC which may not be appropriate for the UK and Europe. A number of recommendations are made concerning the development of DSRC information services and development of standards for tolling.
