Model Results
Figure 1 and Figure 2 contain a daily total volume comparison and a daily truck volume comparison. Daily total volumes are very similar between the two models. There is a slight shift of volume off of I-15 and onto parallel corridors. The largest volume shifts in 2050 are between I-215 and Bangerter Highway. Figure 1 shows one-way volumes.
Daily truck volumes show more differences with volumes dropping between the two models. The drop in volumes is less than a 1,500 trucks per day on freeways but is widespread throughout the region. Figure 2 shows one-way volumes.
