Implementation of sensitivity testing into a national pavement deterioration model: the Transit New Zealand experience

This project identified five key areas that the setup was known to be sensitive to, and confine the tests to these. Guidance on the range of sensitivity to test for each of the variables was provided, such that those areas with the better data and calibration would benefit from a higher level of confidence in the resulting predictions. The parameters identified as being of highest impact to the results were: 1. Traffic loading impacts; 2. Pavement strength (structural number); 3. Cracking calibration factors; 4. Roughness calibration factors and 5. Triggers. This paper discusses all aspects of the project development and the results of the implementation process for the first year of use.
