<br /> 28 <br />unmarked crosswalks (approximately 0.10 or less per 5 years). However, on marked crosswalks, <br />pedestrian crashes increase as traffic ADT increases. <br /> <br />Plots of the final model are given for five-lane crosswalks with a raised median in figures 16 and 17. <br />Average pedestrian ADT is plotted versus pedestrian crashes in figure 16 for traffic ADT of 10,000, and <br />there is little difference in pedestrian crashes at marked versus unmarked crosswalks. Note in figure 17, <br />however, that marked crosswalks have an increasingly greater number of pedestrian crashes than <br />unmarked crosswalks, as ADT increases from 15,000 to 50,000.
