This document provides an overview of the methodology and tools that can be applied to existing micro-simulation and mesoscopic modelling software to assess travel time reliability. The methodology is primarily based on research, and the tools have been developed only at the prototype stage. However, through rigorous testing at different levels of simulation resolution, the framework, the processes, and the tools have been shown to have practical applicability for use by transportation agencies and consultants for policy and project evaluation. Moving beyond the potential applications, one measure of this project’s success would be the adoption of the framework by one or more simulation modelling vendors. Incorporating the principles of the framework and processes into future versions of their proprietary software would lead to wider use of travel time reliability; transportation professionals could easily apply these new metrics in their project and policy evaluation processes that employ particle-based traffic simulation models. The objective of this document is to provide an overview of where and how the methodologies, processes, and tools developed in this SHRP 2 project can be applied. Specifically, the application guidelines provide * A description of the practical applications at both the policy and project level; * A systematic description of the various steps involved in applying the travel time reliability methodology, including an overview of the associated tools and how they function in conjunction with the simulation models; and * Demonstrated evidence of how the methodology can be applied. With regard to the final point, Chapter 7 discusses two case studies that demonstrate how the framework and tools can be applied to potentially real-life transportation planning/engineering situations.
