Page 6H-24 <br /> 2003 Edition <br /> Notes for Figure 6H-10—Typical Application 10 <br /> Lane Closure on 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 <br /> road users approaching from both directions, a single flagger,positioned to be visible to road users <br /> approaching 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 <br /> crest vertical)curve to provide adequate sight distance for the flagger and a queue of stopped vehicles. <br /> Standard: <br /> 5. At night,gagger stations shall be illuminated,except in emergencies. <br /> Guidance: <br /> 6. When used,the BE PREPARED TO STOP sign should be located between the Flagger sign and the <br /> ONE LANE ROAD sign. <br /> 7. When a highway-rail grade crossing exists within or upstream of the transition area and it is anticipated <br /> that queues resulting from the lane closure might extend through the highway-rail grade crossing,the <br /> TTC zone should be extended so that the transition area precedes the highway-rail grade crossing. <br /> 8. When a highway-rail grade crossing equipped with active warning devices exists within the activity area, <br /> provisions should be made for keeping flaggers informed as to the activation status of these warning <br /> devices. <br /> 9. When a highway-rail grade crossing exists within the activity area,drivers operating on the left side of <br /> the normal centerline should be provided with comparable warning devices as for drivers operating on <br /> the right side of the normal centerline. <br /> 10. Early coordination with the railroad company should occur before work starts. <br /> Option: <br /> 11. A flagger or a uniformed law enforcement officer may be used at the highway-rail grade crossing to <br /> minimize the probability that vehicles are stopped within 4.6 m(15 ft)of the highway-rail grade <br /> crossing,measured from both sides of the outside rails. <br />
