Collisions
◦ FHWA Crash Modification Factor (CMF)
◦ 1.694 for lane narrowing from 11 feet to 9 feet
and addition of physical barriers

year
◦ Post-project collision rate is expected to be
1.694 x 2 = 3.39
◦ Collision rate expected to decrease with time
as drivers become familiar with the changes
◦ Collision type is expected to change since
vehicle speeds have been reduced.
4 PostProject
Collisions
◦ 4 total reported collisions since completion
◦ Collision type and severity changed as
expected
◦ Pre-project: ½ of the collisions resulted in
minor injuries
◦ Post-project: No reported injuries
◦ Primary cause of post-project collisions is
distracted driving and drivers not staying in
the travel lane
