4. The volume of traffic was counted for the different hours throughout the year for a certain road. The table below shows the hourly volume of selected hours starting with the highest hourly volume. Plot the relationship between the hourly volume and the hour number. From the graph: a. Comment on the shape of the curve. b. Determine the design hourly volume (DHV). c. If the AADT of this road is 24,000 vpd, calculate the K-value.
