A two-lane rural highway, four-leg intersection will have its stop control replaced by a signal control. Compute the expected average total crash frequency (all types, all severities) after the change for the following conditions: Expected average crash frequency before change: 23 total crashes/yr AADT on minor road: 1500 veh/day AADT on major road: 5000 veh/day
What will be an ideal response?
(a) Determine crash modification factor (CMF). Use Table 5.15:
CMF = 0.56
(b) The expected crash frequency after replacing the stop sign by a signal, will be:
Expected frequency after change = 23×0.56 = 12.88 crashes/year
