6. Countermeasures considered
Traffic Signal
Existing traffic volumes do not meet signal warrant criteria
Could negatively impact safety performance by increasing crash frequency on US 30
Potential is still there for high speed angle and left turn crashes
Signal would violate driver expectations due to limited access/expressway features of US 30
ASD-30 Public Meeting

7. Countermeasures considered cont.
Relocation of SR 603
Provide a more desirable 90O intersection angle
Cost prohibitive due to physical constraints (Charles Mill reservoir and steep embankment)
Potential is still there for high speed angle and left turn crashes
RCUT
ASD-30 Public Meeting

8. Reduces the number of conflict points
BENEFITS OF RCUT
Reduces the number of conflict points
Eliminates severe injury type angle and left turn crashes
Angle and left turn crashes account for 63% of fatal crashes at intersections
Only need to look in one direction at a time

14. Missouri evaluation of J-TURN’S
Analysis of 5 sites converted to RCUT’s
35% total crash reduction
54% reduction in all severe crashes
No fatal crashes post-installation

15. Rcut vIDEO
ASD-30 Public Meeting

16. Common concerns with rcut’S
Nothing needed – spend money elsewhere
RCUT maneuvering
Quick acceleration only to decelerate
Right turn deceleration lanes needed
Shift problems elsewhere
Other crash types
Other intersections
Slow moving and large vehicles
