Determine the crash modification factor (using Table 5.14) that can be used to estimate the change in frequency of the crash type targeted by a proposed improvement that will widen a two-lane rural highway from 18 to 22 ft if the highway has an AADT of 1250 veh/day.
What will be an ideal response?
a) The CMFexist can be calculated according to Table 5.14, for a rural two-lane roadway with 9ft lane width and 400 < AADT < 2000:
b) The CMFnew can be calculated according to Table 5.14, for a rural two-lane roadway with 11ft lane width and 400 < AADT < 2000:
c) The CMF to estimate the change in frequency can be calculated by:

Due to a construction error, the support at D has been constructed 0.6 in. to the left of column BD. Using moment distribution, determine the reactions that are created when the frame is connected to the support and the uniform load is applied to member BC. Draw the shear and moment curves and sketch the deflected shape. E = 29,000 kips/in. 2 and I = 240 in. 4 for all members.
