The OD data was <br />postprocessed and summarized in tables and displayed in GIS figures. <br />Postprocessing raw OD records included two major steps. First, all the OD records were aggregated <br />into 86 OD zones to obtain the total origin and destination trips for each time period, crossing and <br />direction as listed above. Summations were performed to obtain overall trips for the three river <br />crossings regardless of direction. Second, the OD data at this level of aggregation was normalized to <br />obtain the average trips per square mile and were displayed as heatmaps in GIS. The ODs were then <br />further aggregated into jurisdictional city or county levels and were summarized in tables and <br />displayed as labels in the GIS heatmaps. <br />The top trip routes on the highways for each of the crossings were obtained from StreetLight and <br />were then displayed as bandwidth layers in the GIS heatmaps. The trip length and travel times of all <br />the OD trips using the three crossings were summarized in tables and displayed in figures. These <br />maps, tables, and figures are included in the appendix. <br />Origin -Destination Analysis Results <br />The postprocessed OD data is summarized in the following tables described in this section. Results <br />are also illustrated in GIS figures which are described below and are included in the appendix. <br />Table 2 summarizes the total AM (6:00 to 10:00 am), PM (3:00 to 7:00 pm), and daily trips using the <br />three crossings. These are shown by direction for the peak period and daily volumes. The overall <br />percent of traffic each of the three crossings is provided at the daily level. <br />Table 2: Total Trips Using the Three Crossings <br />Duration <br />TH 101 <br />US 169 <br />TH 610 <br />Total <br />SB <br />NB <br />SB <br />NB <br />SB <br />NB <br />SB <br />NB <br />AM (6:00 to 10:00 am) <br />10,228 <br />4,976 <br />6,444 <br />4,050 <br />20,863 <br />11,798 <br />37,535 <br />20,824 <br />PM (3:00 to 7:00 pm) <br />8,620 <br />13,512 <br />5,027 <br />8,516 <br />17,612 <br />27,560 <br />31,259 <br />49,588 <br />Daily <br />32,144 <br />32,320 <br />20,900 <br />21,982 <br />66,692 <br />65,987 <br />119,736 <br />120,289 <br />64,464 (27%) <br />42,882 (18%) <br />132,679 (55%) <br />240,025 (100%) <br />Table 3 identifies the top five communities in terms of the proportion of traffic using each of the <br />three existing river crossings.
