Presentation Transcript

  1. Implementation and continued use of assessment/management method • Changed from January, 2012 to June, 2014 • Only focus on regulatory and warning signs • No requirement to replace signs by certain date Section 2A.08

  2. Ratio of 1” letter height per 30 feet legibility (used to be 40 feet). • Addresses not using punctuation or characters to avoid confusion. • Forward slash intended for fractions and not as a word separator. • Addresses spacing between initials (½ to ¾ of letter height) • For Interstate route in text form, use hyphen. Section 2A.13

  3. Lettering shall be composed of a combination of lower-case letters with initial upper-case letters for: • Places • Streets • Highways Section 2A.13

  4. Increase size • Dual-mount • Header panel • NEW plaque • Flags • Sheeting around perimeter • Beacons • LED-enhancement • Retroreflective support • Other methods as allowed Section 2A.15

  10. New column for Multi-Lane Conventional Highway Section 2B.03

  11. 35 MPH or less – Single Lane column may be used (other than STOP sign) • Dual mounted – Single Lane column may be used (other than STOP sign) • STOP signs – minimum size of 36” x 36” for approaches facing multi-lane roads • If 45 MPH or greater, min. size of STOP signs on side roads shall be 36” x 36” Section 2B.03

  12. Size of regulatory signs on ramps should be based on classification of mainline. Section 2B.03

  13. Portable or part-time STOP signs shall not be used during a power outage unless upon restoration of power: • Flashing red is displayed to that approach, and • STOP sign will be removed prior to stop-and-go operation of the traffic signal Section 2B.04

  14. All WAY plaque shall be used when all approaches must stop. • Supplemental plaques such as 2-way, 3-way, etc. shall not be used. Section 2B.05

  15. Supplemental plaques with appropriate message should be used when all but one approach must stop. Section 2B.05

  16. New/Modified Guidance: • Sign mounted on back of STOP or YIELD signs should not obscure shape (previously excluded DO NOT ENTER signs) • Should install a YIELD on left-side of multi-lane approach to roundabout with a raised splitter island Section 2B.10

  17. New signs may be used at unsignalized pedestrian crosswalks • If used, shall be placed over the roadway at the crosswalk location • Shall not be installed in advance or away from crosswalk Section 2B.12

  18. If used, shall be placed in the roadway at the crosswalk location on the center line, lane line, or on a median island • Shall not be post-mounted on the left or right side of the roadway • Shall not be installed in advance or away from a crosswalk Section 2B.12

  19. Speed zones (other than statutory speed limits) shall only be established on the basis of an engineering study that has been performed in accordance with traffic engineering practices. The engineering study shall include an analysis of the current speed distribution of free-flowing vehicles. Section 2B.13

  20. Reduced Speed Limit Ahead sign should be used where speed limit is reduced by more than 10 MPH • Deleted statement about speed zones being reviewed every 5 years • Defines distance outside of influence of traffic signals as ½ mile Section 2B.13

  21. Should be installed overhead and in advance of signalized intersections with: • Through lanes that become mandatory turn lanes • Multiple-lane turns that include shared lanes for through and turning movements • Other lane use restrictions that • would be unexpected by unfamiliar • road users Section 2B.19

  22. Where overhead mounting is impractical for advance and/or intersection signs, one of the following should be employed: • Where through lanes become mandatory turn lanes, an R3-7 sign should be post-mounted on left-side (for left-lane drops where median is wide enough) and right-side (for right-lane drops) • When median is not wide enough (for left-lane drops) and where multiple-lane turns include shared lanes for through and turning traffic, an Advance Intersection Lane Control sign (R3-8 series) should be posted mounted in a prominent location in advance. Consideration should be given to using an oversized version. Section 2B.19

  23. Where the number of lanes available to through traffic on an approach is three or more, Mandatory Movement Lane Control symbol signs (if used) shall be mounted overhead over specific lanes to which they apply. Section 2B.20

  24. When post-mounted on an approach with two or fewer lanes, a supplemental plaque should be used (used to be a shall). Supplemental sign is now placed above the Lane Control Sign. Section 2B.20

  25. Intersection Lane Control signs at roundabouts may display any of the arrow symbol options shown below: Section 2B.19

  26. May be used to supplement an overhead EXIT ONLY guide sign to inform road users that traffic in the right-hand (left-hand) lane of a roadway is required to depart the roadway on the exit ramp. Section 2B.23

  27. Not a regulatory message. • Has been replaced with a guide sign version. Section 2B.31

  28. Optional use of new, narrow sign when median is less than 4’. • Narrow sign shall not be used if median is less than 4’. • New versions of Keep Left sign: 18” x 30” Section 2B.32

  29. Eliminated words like PROHIBITED and EXCLUDED. New Old Section 2B.39

  30. At an intersection with a divided highway with a median of 30 feet or more, ONE WAY signs shall be placed on the near right and far left corners of each intersection with the direction roadways.Used to be guidance. Section 2B.40

  31. At intersections with a divided highway with a median width less than 30 feet, KEEP RIGHT and/or ONE WAY signs shall be installed. • If used, KEEP RIGHT signs shall be placed as close as possible to the approach ends of the median (visible to crossroad and the divided highway). • If used, ONE WAY signs shall be placed on the near right and far left corners of the intersection (visible to crossroad). • Optional use of ONE WAY signson far right side. Section 2B.40

  32. Deemed significant issue • Compliance date remains unchanged • December 31, 2019. Section 2B.40

  33. At exit ramp terminals where wrong-way entry could inadvertently be made, at least one of each of the following signs shall be used: ONE WAY, DO NOT ENTER, and WRONG WAY sign. • At entrance ramp terminals where the direction of traffic is not evident, a ONE WAY sign visible to both ramp and mainline traffic should be placed on each side of the through roadway. Section 2B.41

  34. New Standards: • On unsignalized minor-street approaches from which both left and right turns are permitted onto a divided highway with a median width of 30’ or more, a Divided Highway Crossing sign shall be installed. • Sign shall be located on the near right corner of the intersection mounted beneath a STOP/YIELD sign or on a separate support. (used to be optional statements) • New Option: • Sign not required if divided highway ADT is less than 400 and speed limit is 25 mph or less. Section 2B.42

  35. New Guidance: • Where the central island allows for installation of signs, Roundabout Direction Arrow signs should be used to direct motorists counter-clockwise. • Signs shall only be used at roundabouts. • Mounting height should be 4’ to bottom of sign. • ONE WAY signs may be used instead of R6-4 signs. Section 2B.43

  36. Where the central island of a roundabout does not provide a reasonable place to install a sign, Roundabout Circulation plaques should be placed below the YIELD signs on each approach. Section 2B-43

  37. Section 2B.45

  38. Section 2B.45

  39. Section 2B.45

  40. Signs should be used to define area of pay station parking. • If pay parking is subject to a maximum time limit, the time limit shall be displayed on the Pay Parking/Pay Station signs. Section 2B.47

  41. Section 2B.53

  42. May use blankout version of sign to display restriction during certain times of the day or certain parts of the cycle. • May use new signs to control right-turns on red from approaches with more than one right-turning lane. Post-mount Overhead Section 2B.54

  43. New option – allows use of rectangular/square shape signs for those larger than Oversize column. • New option – allows for minor modifications to standard warning signs (except for symbols). • New option – allows for use of word messages other than those provided in the MUTCD. Section 2C.03

  44. New standard – 36” x 36” minimum size for diamond warning signs on multi-lane conventional highways with speed limit > 35 MPH. • New option – allows smaller, Single Lane size signs on multi-lane highways if dual-mounted. • New guidance - size of warning signs on ramps should be based on classification of mainline.
