Digital data from emerging sources such as GPS, Bluetooth and weigh-in-motion is currently captured in New Zealand for a range of traffic monitoring purposes. This research project was undertaken to provide guidance on what capacity exists to assess the performance of the state highway road network using these digital data sources.
This report summarises the background research, model development and delivery, and future opportunities to understand the performance of the state highway road network, both spatially and over time, using emerging digital data technologies.
This research initially explored how the various data sources could inform a range of network indicators covering private and public transport modes, safety, environment, activity and cost. A GIS-based proof-of-concept model was developed to demonstrate how currently available data sources could inform these indicators, which were then displayed in a web viewer that could be used to help the NZ Transport Agency measure the performance of the state highway network.
This report also includes a business-case for the roll-out of the proof-of-concept model to a nationwide-level, including an assessment of opportunities and risks, and recommendations for engaging with third party data suppliers.
