TRB will conduct a webinar on Wednesday, March 14, 2018 from 2:00 PM to 3:30 PM ET that will explore the relationship between vehicle speed and fuel economy as investigated by the U.S. Federal Highway Administration. This webinar will describe how to simulate real-world vehicle operations using driving cycles in order to improve vehicle operating cost estimations. Presenters will discuss how vehicle speeds and fuel economy were modeled within an array of vehicle types, traffic conditions, and road properties.

This webinar was organized by the TRB Standing Committee on Structural Requirements of Asphalt Mixtures.

Some registrants will need to pay $95 to attend this webinarSign into to view registration information.

Webinar Presenters

  • Elie Hajj, University of Nevada, Reno
  • Hao Xu, University of Nevada, Reno
  • Gary Bailey, Nevada Automotive Test Center
  • Muluneh Sime, Nevada Automotive Test Center

Moderated by:  Valentin Vulov, U.S. Federal Highway Administration

Webinar Outline

  1. Development of synthetically optimized driving cycles for full access control and partial or no access control
  2. Estimation of fuel economy using vehicle simulation modeling
  3. Fuel economy prediction models for full access control and partial or no access control
  4. Summary and conclusions
  5. Question and answer session

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.

Learning Objectives

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

  • Apply developed prediction models to estimate vehicle fuel consumption as a function of road grade level
  • Assess the influence of traffic congestion level on fuel consumption
  • Assess the influence of the number of signalized intersections on fuel consumption
  • Assess the excess in fuel consumption due to road curvatures

Professional Development Hour Information

A certificate for 1.5 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups, only the person that registers and attends the session will receive a PDH certificate. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in October 2017. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
