Overview
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 of investigation for the original research to be conducted in Phase II. During this task, the TTI team analyzed the information from the previous tasks to hone the research efforts to ensure that a manageable and realistic experimental design will be developed for the remainder of the project. The reality is that not enough time nor dollars exist to examine every feasible combination of technology platforms, communications channels, message sets, and message formats to arrive at a single solution to the challenge of disseminating travel time reliability information. Thus, this task focuses on summarizing the key gaps that emerged from Tasks 1‐3 related to the most effective means of communication reliability information to travelers.
