Samenvatting
Reports on the NAASRA Roads Study (NRS) and the Bureau of Transport Economics Assessment of the Australian Road System acknowledge the difficulty in assembling data and drawing conclusions about changes in the road network, and in the traffic service on the network. The various Quality of Service concepts used in the NRS and other measures for monitoring the performance of the road network at a macro level are examined. The paper also examines the emerging requirement to develop performance indicators for the monitoring of programs and organization effectiveness.
