Table III shows how the growth in trips in the four quadrants of <br />the interchange are calculated. F~cisting trips from these areas must be subtracted from the total <br />a.m. and p.m. peak hour 2030 trips to and from the interchange. The objective is to determine what <br />percentage of trips in the four quadrants of the interchange use the interchange versus all other <br />locations. Table III provides the detailed data for this calculation. <br />Table II1: Calculation of Trip Growth, 2005 to 2030 and Proportion of Interchange Trips <br /> <br />Y <br />T <br />i <br />C <br />i Total Trigs D Trips Trips tolfrom Project Trips <br />ear r <br />p <br />ategor <br />es <br />o.m. + p.m. <br />2005 -~ 2030 <br />ICI and Kaiser <br />in Quadrants 1 - 4 <br /> Project Trips Using Interchange 6,914 20 `''` <br />2005 All Trips Using Interchange 7,924 ~- ' " <br /> Quadrant Trips to/from All Locations 23,512 20 ~- <br /> Project Trips Using Interchange 11,956 5,042 3732 I ,3 I 0 <br />2030 All Trips Using Interchange 14,814 6,890 s <br /> Quadrant Trips to/from All Locations 36,704 13, 192 6894 6,298 <br />Notes: Project Trips =Trips from Quadrants I - 4 using Marina/I-880 Interchange (excludes Kaiser/ICI) <br />All Trips =All traffic using interchange including Project Trips (includes Kaiser/ICI) <br />Quadrant Trips =Trips to/from Quadrants I - 4 to all locations <br />Page 9 <br />Final Report - Traj~ic Impact Fee Analysis for I-880/Marina Interchange Improvement November 12, 2009 <br />
