Development and Application of a Travel Time Reliability Estimation Method for Freeways

The research reported in this paper developed a methodology and tools for estimating travel time reliability measures, and implemented these on a freeway section and the freeway network of a large metropolitan area. The paper first provides a brief overview of travel time reliability approaches, followed by an overview of the methodology. Next, example applications for implementing the tools developed on a freeway section in South Florida are presented. It was concluded that the tools developed can be applied to provide travel time estimates which can be used to make systems planning and project development decisions. It is noted that the methods and results presented here are the first effort to estimate travel time reliability on freeways and it is expected that many refinements will be added for accuracy, but also to facilitate the use of the tool for additional applications.
