Abstract
The goal of DYNA, an EC DRIVE II project, is to build and evaluate an on-line monitoring and prediction system for inter-urban motorway networks. The paper describes the system architecture, which comprises two dynamic representations of the network traffic process: O/D flows and link densities reflecting both choice behaviour and traffic flow physics. Predictions on the traffic state, with a rolling horizon of up to 60 minutes, is output to the traffic operator. The paper describes the pilot application in which the models are tested and the overall evaluation of the complete system; it ends with a discussion of intra-urban and control extensions. (A)
