<strong>The Cost of Wider Fire Access Codes (Supplementary Material)</strong>

There are 4 files which supplement my manuscript. Excel File <em>Raw Data</em> contains elements including street name, street width, dwelling units, neighborhood area, and parking characteristics. <br> Neighborhood averages were copied to the Excel file <em>Measurement Summary</em> for additional analysis. <br> More detailed statistical calculations were performed using Texas Instruments TI-nspire software. Outputs are available in the PDF <em>Statistical Calculations</em>. <br> Following review, the paper’s methodology was simplified. The simplified methodology produces the same result as the original process, and the older calculation files were not modified. The Excel file <em>Updated Street Width Formulas</em> displays both processes side by side.
