Details

Pavement smoothness (or roughness) is used by state highway agencies for monitoring network condition as well as assessing construction quality and optimizing investments in preservation, rehabilitation, and reconstruction. States are also required to report the International Roughness Index (IRI) as an element of the federal Highway Performance Monitoring System. TRB will host a webinar on Tuesday, March 22, 2022 from 2:00-3:30 PM Eastern that will cover current practices for estimating roughness of low-speed and urban roads as well as the challenges associated with collecting data. Presenters will review the calculations for determining IRI. They will cover the unique features of low-speed and urban roads that may yield inappropriate and misleading data. Presenters will offer both a short-term and long-term solution.

This webinar is sponsored by the TRB Standing Technical Committee on Pavement Surface Properties and Vehicle Interaction.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100.

Webinar agenda and presenters

  1. Introduction to the issues: Steve Karamihas, University of Michigan Transportation Research Institute
  2. Reducing errors at stops with error suppression algorithms: Robert Orthmeyer, Federal Highway Administration
  3. Eliminating measurement errors at low speed, stops, and during grading with sensor augmentation: Brian Schleppi, Ohio Department of Transportation (retired)
  4. Question and answer session: LaDonna Rowden, Illinois Department of Transportation

 

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

Learning Objectives

At the end of this webinar, participants will be able to:

  1. Define urban profile measurements
  2. Identify where errors can occur in urban profile measurements
  3. Identify errors and methods to minimize errors of stop-and-go and equipment improvement
