... Both methods primarily use data types that would typically be available to practitioners, such as turning movement counts, basic signal timing data, and basic intersection attributes. The resulting RTOR volume estimates can be used with existing implementations of the HCM methodology by adjusting the input volume for right-turn movements, while the alternative capacity expression requires adjustment of the capacity calculation method internal to signal analysis models.

... 1.2  Overview of the Spreadsheet Tool The main purpose of the spreadsheet tool that the research team developed is to allow a user to view estimated RTOR-adjusted volumes and capacities based on mathematical models devel oped as part of this project. The development of a complete capacity model duplicating the HCM Computational Engine or commercial tools like Highway Capacity Software, with full capabilities, was beyond the scope of this study.
