Description

This report identifies and evaluates technology solutions that meet asset management needs relating to road pavement performance. The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for a lower cost. The report summarises current and emerging data collection technologies, and proposes and tests a technology evaluation framework. The evaluation of emerging technologies found existing equipment, such as mobile phones, was often repurposed to develop new methods of data collection. While this occasionally results in lower accuracy, this is consistently offset by high affordability and other strengths such as higher frequencies of data collection, data redundancy and secondary benefits. Accordingly, even emerging data collection technologies with relatively low accuracies have a role to play in addressing the data needs of road controlling authorities, and may be used to augment, rather than replace, existing data collection programs
