Source: Omni-Means 2005. Roadway Traffic Index Values _ Two sets of calculations for TI values were made for each of the studied traffic conditions-one that considered an overall TI value and one that considered whether trucks were loaded or empty. Table 3.L-35 presents the calculated increase in TI values resulting from the proposed Project on Bird Road, Blewett _ Road,and Koster Road just south of the DeSilva Gates quarry entrance for existing (10-year TI value),and year 2007 (10-year TI value)traffic conditions. The calculated TI does not differentiate between loaded trucks traveling one way on the study area roadways with empty trucks traveling the opposite direction.
