California MUTCD (FHWA's MUTCD 2003 Revision 1,as amended for use in California) Page 6G-5 Guidance: Where pedestrian or bicycle usage is high, the typical applications should be modified by giving particular attention to the provisions set forth in Chapters 6D and 6G, Section 6F.68, and in other Sections of Part 6 related to accessibility and detectability provisions in TTC zones. Pedestrians should be separated from the worksite by appropriate devices that maintain the accessibility and detectability for pedestrians with disabilities. Bicyclists and pedestrians should not be exposed to unprotected excavations, open utility access, overhanging equipment, or other such conditions. Except for short duration and mobile operations, when a highway shoulder is occupied, a SHOULDER WORK sign should be placed in advance of the activity area. When work is performed on a paved shoulder 2.4 m(8 ft) or more in width, channelizing devices should be placed on a taper having a length that conforms to the requirements of a shoulder taper. Signs should be placed such that they do not narrow any existing pedestrian passages to less than 1200 mm(48 in). Pedestrian detours should be avoided since pedestrians rarely observe them and the cost of providing accessibility and detectability might outweigh the cost of maintaining a continuous route. Whenever possible, work should be done in a manner that does not create a need to detour pedestrians from existing routes or crossings. Standard: Where pedestrian routes are closed, alternate pedestrian routes shall be provided. When existing pedestrian facilities are disrupted, closed, or relocated in a TTC zone,the temporary facilities shall be detectable and shall include accessibility features consistent with the features present in the existing pedestrian facility. Section 6G.06 Work Outside of Shoulder Support: Chapter 6D and Sections 6F.68 and 6G.05 contain additional information regarding the steps to follow when pedestrian or bicycle facilities are affected by the worksite. When work is being performed off the roadway(beyond the shoulders, but within the right-of-way), little or no TTC might be needed. TTC generally is not needed where work is confined to an area 4.6 m(15 ft)or more from the edge of the traveled way. However, TTC is appropriate where distracting situations exist, such as vehicles parked on the shoulder, vehicles accessing the work site via the highway,and equipment traveling on or crossing the roadway to perform the work operations (for example, mowing). For work beyond the shoulder, see Figure 614 1 6H-1(CA). Guidance: Where the above situations exist, a single warning sign, such as R )WO W z" T n n Workers _ 1 a)sign, should be used. If the equipment travels on the roadway, the equipment should be equipped with 121 appropriate flags, high-intensity rotating, flashing, oscillating, or strobe lights, and/or a SLOW MOVING VEHICLE sign. Support: Refer to Section 6F.31 for Workers(W21-1a)sign. Option: If work vehicles are on the shoulder, a SHOULDER WORK sign may be used. For mowing operations, the sign MOWING AHEAD may be used. Where the activity is spread out over a distance of more than 3.2km(2 mi), the SHOULDER WORK sign may be repeated every 1.6 km(1 mi). A supplementary plaque with the message NEXT X le*(MILES) may be used. Guidance: ' A general warning sign like ROAD MACHINERY AHEAD should be used if workers and equipment must occasionally move onto the shoulder.
