Transportation technology developers are invited to a TRB webinar on Tuesday, September 17, 2019, from 2:00 PM to 3:30 PM ET. The webinar will provide an overview of the demographics and characteristics of the visually impaired population and discuss the implications of technologies developed to aid this population. Developers of wayfinding or safety technologies intended to help the visually impaired may make incorrect assumptions that lead to interfaces or products that are too complex for users and don’t address the real problems the population faces. Presenters will provide research-based information about the evaluation of technologies, including what is most important to the visually impaired, meaningful and practical measures of technology effectiveness, and the relative merits of subjective evaluation of technologies and human factors testing.

This webinar was organized by the TRB Standing Committees on Accessible Transportation and Mobility and User Information Systems.

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

Learning Objectives

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

  • Describe demographics of the population of people who are visually impaired and identify the implications of these characteristics for user interfaces
  • Determine meaningful measures of improvement in wayfinding or safety for travelers who are visually impaired
  • Describe the benefits and disadvantages of subjective evaluation of technologies
  • Discuss the necessity for human factors testing in the natural environment

 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.
