Traffic operations and management practitioners were invited to a TRB webinar on Thursday, August 22, 2019, from 1:00-2:30 PM. This webinar discussed the proposed chapters for incorporating travel time reliability into the
Highway Capacity Manual (HCM), Sixth Edition: A Guide for Multimodal Mobility Analysis. HCM is commonly used by transportation agencies to evaluate and forecast operations of roadway facilities. An updated version will be released next year.
Travel time reliability aims to quantify the variation of travel time and is defined using the entire range of travel times for a given trip, for a selected time period (for example, the peak period on weekday afternoons), and over a selected horizon (for example, a year). Measuring travel time reliability requires that a sufficient history of travel times be present to track travel time performance. Presenters identified travel time distribution for a given trip. They also described how to apply travel time reliability methods to the analysis of freeways, urban streets, and corridors.
This webinar was organized by the TRB Standing Committee on Highway Capacity and Quality of Service. It is the third in a series of webinars about the HCM. The first two were conducted on
June 10, 2019 and
July 29, 2019.
The
slides are available. Contact
Reggie Gillum for a copy of the recorded webinar.

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 approved webinars,
TRB’s webinar program awards Registered Continuing Education Provider (RCEP) Professional Development Hour (PDH) credits associated with participation only to the registered individual and not to other members of a group that view the webinar together. To receive PDH credits, please register as an individual and sign into the webinar from your personal computer. After doing this, you may join your group in a meeting room. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.
In addition, advance registration is available until just before the webinar starts. Once the webinar starts, you will be unable to submit your registration. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact the TRB Helpdesk (
MyTRB@nas.edu) for assistance in signing in.
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 RCEP.net 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 March 2019. 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
