4. Provide all-red clearance intervals at signalized intersections5. Provide more protected left-turn signal phases at high-volume intersectionsOther signal enhancements:—Background shields—Larger signal heads
7. Improve lighting at intersections, horizontal curves, and railroad crossings
9. Replace painted channelization with raised channelization
