Part 3 – Markings
2
Dotted (not broken) lane lines shall be used for non-continuing lanes: Lane drops Auxiliary lanes Deceleration lanes Acceleration lanes Applies on freeways, expressways, and conventional roads
5
2 miles or less
6
1 mile or less Now to be wide dotted lane line
9
Replace existing broken lane lines with dotted lane lines for non-continuing lanes: December 31, 2016 or resurfacing, whichever occurs first
10
2009 MUTCD Standard for all exit and entrance ramps Channelizing lines shall be placed on both sides of the neutral area 2003 MUTCD
11
Lane Reduction Markings Lane line – NO CHANGE from 2003 Lane reduction arrows should be used if speed limit is > 45 mph [new w/ 2009] -Not applicable to typical parallel accelleration lanes, but: -May use lane-reduction arrows in long acceleration lanes based on engineering judgment OPTION to delete edge line and delineators in transition for low-speed urban locations with curbs [new w/ 2009]
13
New marked crosswalks alone, without other measures designed to reduce traffic speeds, shorten crossing distances, enhance driver awareness of crossing, and/or provide active warning of pedestrian presence should not be installed across uncontrolled roadways with: - ≥4 travel lanes - Speed limit >40 mph, and - ADT > 12,000 without raised median or pedestrian refuge, or - ADT > 15,000 with raised median or pedestrian refuge
14
Optional use of pavement markings simulating route shield signs
15
New section includes support, guidance, and standards for chevrons and diagonal crosshatch markings < 45 mph: Min. 8” wide > 45 mph: Min. 12” wide Spacing: Engineering Judgment 30 – 45 degrees +/-
16
Updated practices for pavement markings at roundabouts, including lane lines, edge lines, yield lines, crosswalk markings, and pavement word, arrow, and symbol markings
17
Optional fish-hook lane-use arrows for approaches to roundabouts
18
Delineators should be used with guardrails and other barriers
19
Option for “ribbon” delineation on the face of guardrails or barriers
20
Standard specifies that for channelizing devices outside of temporary traffic control zones, retroreflective bands shall be white if devices separate traffic flows in same direction and yellow if the devices separate traffic flows in opposing directions
