Project Dates: Oct 1, 2017 - Mar 31, 2019
Effective performance measurement provides benchmarking for transportation agencies to promote transparency, accountability, cost-effectiveness, and process improvement. Vaisala's proprietary "Grip" measure provides an imputed measure of the condition of the road surface. VTrans' Average Distribution Deviation (ADD) measures changes in the distribution of vehicle speeds during and after winter weather events. This project found that ADD and Grip were relatively pooly correlated, indicating that each measure is independently useful and one cannot be used as a proxy for the other.
