Assessing driver understanding of travel-time reliability

Researcher: Laura Higgins

Sponsors: Federal Highway Administration and American Association of State Highway and Transportation Officials

In the second phase of efforts to study driver understanding of travel-time reliability information and the best way to inform drivers of that information, TTI will conduct advanced laboratory studies nationwide. This effort will use results gathered from the previous year’s usability studies to compare selected terms to develop a bank of words that can be used to effectively communicate reliability information to drivers. Phase two will also include collecting data on driver understanding of graphical displays and testing audio and visual information.
