Exhibit 3-15 is a bar graph that shows small urban and urbanized lane width by functional system in 2000. The vertical axis has five bars with five parts each. The horizontal axis measures percentages from 0 to 100 in increments of 10 percent. The first group of bars, for interstates, shows that 98.2 percent of rural lanes have a width of 12+ ft., 1.7 percent have a width of 11 ft., 0.1 have a width of 10 ft., 0.00 have a width of 9 ft., and 0.00 have a width of less than 9 ft. The second group of bars, for other freeways and expressways, shows that 95.9 percent of small urban and urbanized lanes have a width of 12+ ft., 2.9 percent have a width of 11 ft., 1.0 have a width of 10 ft., 0.2 have a width of 9 ft., and 0.00 have a width of less than 9 ft. The third group of bars, for other principal arterials, shows that 79.3 percent of small urban and urbanized lanes have a width of 12+ ft, 13.4 percent have a width of 11 ft., 6.7 have a width of 10 ft., 0.4 have a width of 9 ft., and 0.2 have a width of less than 9 ft. The fourth group of bars, for minor arterials, shows that 66.0 percent of rural lanes have a width of 12+ ft., 16.3 percent have a width of 11 ft., 14.6 have a width of 10 ft., 2.6 have a width of 9 ft., and 0.5 have a width of less than 9 ft. And the fourth group of bars, for collectors, shows that 52.7 percent of rural lanes have a width of 12+ ft., 16.5 percent have a width of 11 ft., 21.2 have a width of 10 ft., 7.0 have a width of 9 ft., and 2.6 have a width of less than 9 ft.
