This research project develops measurable criteria for the economic value of the movement of people and goods for use in the One Network Road Classification and contributes to the development of a performance measurement framework. The research focused on improving the measurement of the overall movements on a road, by supplementing vehicle counts with public transport patronage data, which contributes to the understanding of the total overall use of a road and the output roads support.
The research also explored productivity indicators for roads, based on the output roads support and the input costs of roads. We develop four indicators on this basis:
Our research specifically considers costs to generate estimates of the productivity of roads, which enables stronger correlation with performance measures. Finally, we explore the second best route productivity indicator. The opportunity cost of a road is considered by a marginal analysis of transport costs if the next best alternative road is instead used. The second best route productivity indicator is the most promising avenue to estimate the absolute productivity of a road, which could be refined and further developed for performance management purposes.
