    • Abstract:
      It’s widely accepted that smooth roads provide greater driver comfort and satisfaction, decreased vehicle maintenance costs, and better fuel economy. Now thanks to a recently completed study, the affect of pavement smoothness on fuel efficiency has been confirmed for Missouri drivers on Interstate 70. Specifically, the study examined the miles per gallon in fuel savings for smooth versus rough pavement. The study found that a 53 percent improvement in road smoothness, as part of the Smooth Roads Initiative, resulted in a 2.46 percent improvement in miles per gallon for large trucks. With approximately 9,000 trucks per day on I-70, over the course of a year the annual fuel savings would be 3,120,750 gallon of diesel. At the Nov. 16 average price per gallon of $2.56, the annual cost savings would be $7,989,120.
