| Research Abstract |
Travel time reliability is an emerging evaluation measure for highway network service levels. This paper focuses on travel time reliability indexes for a highway network and proposes new travel time reliability indexes. The paper also discusses and compares several previously and newly proposed indexes for use by both highway users and operators qualitatively. Because this comparative study requires travel time variation, a model is developed for estimating travel time variation. It is the multi-hierarchical stochastic model for estimating travel time variation under uncertainty in demand and service. Then, new indexes for assessing travel time reliability are proposed. The indexes are compared quantitatively.
