Project Summary

The recent community survey found that there was a 17% increase in the negative perception on the smoothness of roads. We do not use smoothness of roads as a pavement condition index as it was found that it is a perception issue instead of a distress issue. It can be measured using the international roughness index which is used by TDOT for a payment factor on interstate highways. Smoothness tends to be more critical on high speed roadways but since the community is surveyed for this particular issue, it may provide valuable information to have an additional objective rating for smoothness when evaluating the resurfacing list.
In order to quantify the roughness of our streets I propose a project to collect international roughness index (IRI) and pavement distress data on all City streets.
It is estimated that the replacement cost of the roadway system is approximately $2 billion dollars and the pavement distress data and the IRI data collection would be approximately $400,000 dollars.
This is 0.02% of the network value.
