What is it about?
Using this method will provide repeatable roughness measurements for any road, while traveling at any speed, in any type of vehicle. Unlike other approaches such as the International Roughness Index that estimates the quality of the ride (ride-quality) based on simulations of a simplified vehicle response model, this approach is a direct measurement of the roughness that a vehicle occupant actually experiences.

Why is it important?
This approach leverages the emergence of connected vehicles by providing greater precision and accuracy with every additional vehicle probe data processed.
Perspectives
Connected vehicles are now emerging, and standards to use the data from their various embedded accelerometers are not yet in place. However, agencies can use the approach in the interim by collecting the required data with a smartphone app. The free PAVVET app is currently available for the iOS. An android version is currently in development.
