6F.01 – Types of Devices Support: FHWA policy that work zone devices meet NCHRP Report 350
Section 6F.02 General Characteristics of Signs New table format, Table 6F-1 Sizes of Temporary Traffic Control Signs showing the sizes of temporary traffic control warning signs is added
Section 6F.03 Sign Placement Support: If alterations are made to specific traffic control device supports that have been successfully crash tested in accordance with NCHRP Report 350, the altered supports might not be considered to be crashworthy.
Section 6F.14 Special Regulatory Signs Support: signs to enhance speed enforcement
Section 6F.15 Warning Sign Function, Design and Application Exit and Detour signs included in new Figure 6F-5
Section 6F.15 Warning Sign Function, Design and Application Speed Reduction Signs design changed from Regulatory to Warning. Sign sizes removed from Figure
Section 6F.40 TURN OFF 2-WAY RADIO AND CELL PHONE Sign (W22-2) CELL added to sign message
Section 6F.56 Arrow Panels Guidance: Arrow panel at start of taper
Section 6F.56 Arrow Panels Used to: Close lanes – OK Shift Traffic- NO
Section 6F.58 Channelizing Devices Guidance: -Should be crashworthy -Fragments/debris should not pose significant hazard to road users or workers Compliance date January 17, 2005
Figure 6F.58 Channelizing Devices Figure 6F-7 Lumber barricades have not passed NCHRP 350 crashworthiness testing.
Section 6F.59 Cones Standard added on cones greater than 36 in height Minimum of 4 retroreflective bands Phase-in target compliance date 5 years
Section 6F.63 Type I, II, or III Barricades 2nd Guidance paragraph replacing Standard Ballast shall not protrude into Pedestrian Path
Section 6F.66 Longitudinal Channelizing Barricades Guidance: should conform to the general characteristics established for the devices described in Chapter 6F re: - size - color - stripe pattern - retroreflectivity - placement.
Section 6F.67 Other Channelizing Devices. New Section added -Optional device -Guidance: conform to other Sections in Chapter 6F re: - Size - Color - Stripe Pattern - Retroreflectivity - Placement
Section 6F.68 Detectable Edging for Pedestrians New Section added: Guidance: -Protrude min. 150 mm (6 in) above surface at top -Bottom of edging max. 62 mm (2.5 in) above surface -Continuous except gaps for turning or crossing
Section 6F.69 Temporary Raised Islands Standard---Temp. Raised Islands at Pedestrian Crossings: Opening or shortened to provide at least 1500 mm (60 in) wide ped pathway
Section 6F.70 Opposing Traffic Lane Divider Standard: DONT placed across PEDESTRIAN CROSSINGS
Section 6F.72 Temporary Pavement Markings Option: Half-cycle lengths w/ min. 0.6 m (2 ft) stripes may be used on roadways w/ severe curvature for centerlines in passing zones and for lane lines. For temporary situations of 3 calendar days or less, for a 2- or 3-lane road, no-passing zones may be identified by: Guidance: if used, place as per Sections 2B.29, 2B.30, 2C.35
Section 6F.75 Lighting Devices Guidance: Max. spacing same as channelization devices
Sections 6F.75 Lighting Devices Option---lights on maintenance vehicles for daylight maintenance operations
