... 133 APPENDIX D: BENEFIT-COST ANALYSIS TOOL Section 4.3.1 describes the concept of the Excel spreadsheet-based BCA tool to support the economic case component of the business case. This appendix provides further background on the V2I applications available in the tool and instructions on how to use the tool to compute benefit-cost ratios as an input into the economic case.

... 136 The BCA tool offers maximum flexibility to the user to disregard any given cost or benefit category based on his or her preference and the availability of data. The cost and benefit categories and input guidance are based on currently available knowledge and may evolve as CV development and deployment reaches advanced states of maturity.

... 146 The environmental benefits calculation begins with an estimate of the reduction rates in the three pollutants and fuel consumption as a result of the V2I application. For SPD-HARM, the default reduction rates provided in the BCA tool are based on simulations of a speed harmonization algorithm applied to a section of I-66 in Northern Virginia (Virginia Tech Transportation Institute 2016)
