SHRP 2 Project L03, which concluded in 2010, developed two categories of reliability models to be used for the estimation or prediction of travel time reliability within planning, programming, and systems management contexts: data-rich and data-poor models. The objectives of Project L33 were the following: \u2022 The first was to validate the most important models \u2013 the \u201cData Poor\u201d and \u201cData Rich\u201d models with new datasets. \u2022 The second objective was to assess the validation outcomes to recommend potential enhancements. \u2022 The third was to explore enhancements and develop a final set of predictive equations. \u2022 The fourth was to validate the enhanced models. \u2022 The last was to develop a clear set of application guidelines for practitioner use of the project outputs.
