TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-L14-RW-1: Effectiveness of Different Approaches to Disseminating Traveler Information on Travel Time Reliability provides recommendations on appropriate ways to introduce and provide travel time reliability information to travelers so that such information can be understood and used in a way that influences their travel choices, but does not present a safety hazard.
Reliability Project L14 also produced a report Lexicon for Conveying Travel Time Reliability Information, that includes a glossary of terms designed to convey travel time reliability information to travelers so that such information can be understood and used in a way that influences their travel choices, but does not present a safety hazard.
