The project's goal was to develop consistent definitions and a unified modeling framework for transportation professionals to help them better understand the opportunities and challenges associated with MRM. This state-of-practice and gap analysis report provides a review of MRM terminology, tools, and literature. It further reports the outcomes from a series of teleconferences with 19 agencies and companies with a vested interest in MRM. These discussions found increased interest in MRM as a means to make simulation results more defendable. However, the study found that there are still issues facing agencies that utilize or desire to utilize MRM as part of their modeling practices. These findings will provide an important point for future advancement in the research, development, and application of MRM in transportation engineering.119
