Changeable message signs (CMSs), sometimes referred to as dynamic message signs or variable message signs, are being used nationwide to provide real-time information to drivers. Among the messages displayed are time-related messages. The following five time-related approaches are available for di
The SHRP 2 Reliability program aims to improve trip time reliability by reducing the frequency and effects of events that cause travel times to fluctuate in an unpredictable manner. Congestion caused by unreliable, or non-recurring, events is roughly as large as congestion caused by routine bottl
The second Strategic Highway Research Program (SHRP 2) Reliability program aims to improve trip time reliability by reducing the frequency and effects of events that cause travel times to fluctuate unpredictably. Congestion caused by unreliable, or nonrecurring, events is roughly as extensive as
Tasks 1 through 3 of this project examined previous literature, state‐of‐the‐art technology and future trends, and expert opinion concerning the dissemination of travel time reliability information. Based on the results of these tasks, the project team formulated a focused set of paths
Traveler information can be acquired by travelers today through a number of media. These media range from traditional roadside signage and broadcast media to newer electronic wireless and web‐based media. The resulting mix of traffic and transportation system status data has
The human factors studies planned for Tasks 6‐10 were presented and approved by the panel in June 2010. They consisted of focus groups and a usability study. As conceived at that time, the usability study would employ computer‐based multiple choice testing of terminolo
The TTI research team conducted nine telephone interviews in February 2010. The purpose of the interviews was to gather information regarding the state‐of‐the‐practice of disseminating travel time reliability information. TTI researchers conducted interviews with experts in
