California MUTCD 2012 Edition Page 1157 <br /> (FHWA's MUTCD 2009 Edition,as amended for use in California) <br /> Notes for Figure 614 10 614-10(CA)—Typical Application 10 <br /> Lane Closure on a Two-Lane Road Using Flaggers <br /> Option: <br /> 1.For low-volume situations with short work zones on straight roadways where the flagger is visible to road <br /> users approaching from both directions,a single flagger,positioned.to be visible to road users approaching <br /> from both directions,may be used(see Chapter 6E). <br /> 2.The ROAD WORK AHEAD and the END ROAD WORK signs may be omitted for short-duration <br /> operations. <br /> 3.Flashing warning lights and/or flags may be used to call attention to the advance warning signs. <br /> A BE PREPARED TO STOP sign may be added to the sign series. <br /> Guidance: <br /> 4. The buffer space should be extended so that the two-way traffic taper is placed before a horizontal(or crest <br /> vertical)curve to provide adequate sight distance for the flagger and a queue of stopped vehicles. <br /> Standard: <br /> 5.At night,flagger stations shall be illuminated,except in emergencies. <br /> Guidance: <br /> 6. When used, the BE PREPARED TO STOP sign should be located�n after the Flagger sign and the I <br /> ONE LANE ROAD sign. <br /> 7. When a grade crossing exists within or upstream of the transition area and it is anticipated that queues <br /> resulting from the lane closure might extend through the grade crossing, the TTC zone should be extended <br /> so that the transition area precedes the grade crossing. <br /> 8. When a grade crossing equipped with active warning devices exists within the activity area,provisions <br /> should be made for keeping flaggers informed as to the activation status of these warning devices. <br /> 9. When a grade crossing exists within the activity area, drivers operating on the left-hand side of the normal <br /> center line should be provided with comparable warning devices as for drivers operating on the right-hand <br /> side of the normal center line. <br /> 10.Early coordination with the railroad company or light rail transit agency should occur before work starts. <br /> Option: <br /> 11.A flagger or a uniformed law enforcement officer may be used at the grade crossing to minimize the <br /> probability that vehicles are stopped within 15 feet of the grade crossing,measured from both sides of the <br /> outside rails. <br /> Support: <br /> 12. For State highways,see Department of Transportation's Standard Plan T13.See Section 1A.11 for information <br /> regarding this publication. <br /> i <br /> I <br /> i <br /> i <br /> Chapter 6H—Typical Applications January 13,2012 <br /> Part 6—Temporary Traffic Control <br /> Temporary Traffic Control(Parts 1 &6)Page 215 of 320 <br />
