The pavement deterioration modelling space has been explored for over 20 years now, and there are still advancements being made in the modelling space. The growth of the technical capital in this space has increased dramatically in recent years due to advancements in data and technology.
However, how can we ensure that all the useful output from our various models are being utilised to deliver a comprehensive understanding of the big picture?
In recent years, the primary challenge has not been getting the results – it has been ensuring that these results are understood and are being addressed appropriately. It has been about “telling the story”.
This presentation will briefly touch upon the deterioration modelling process but focus on covering a variety of strategies that we have employed for the NLTP 2021-2024 plan to provide confidence in the modelled outcomes. These methods include simply extending the timeframe of modelled outcomes from the typical 20 years to 30 years, but also more complex risk models to include multiple different sensitivity analyses.
