For lou--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. Plashing 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 buffet-space should be extended so that the livo-way ti-affrc taper is placed befoa•e a horizontal(o•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. 91hen used, the BE PREPARED TO STOP sign should be located heAveeii-after the Flogger sigil and the <br /> ONE LANE ROAD sign. <br /> 7. Wlreiz i grade crossing exists within or upstream of the transition area and it is anticipated that queues <br /> resulthrg fi•oni the lane closure might extend through the grade crossings; the TTC zone should be extended <br /> so that the h ansition area precedes the grade crossing. <br /> 8. When a grade ci-ossing equipped with active warning devices exists within the activity area,provisions <br /> should be►rade for keeping fIaggers it formed 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 oil the right-hand <br /> side of the 1701-177al center line. <br /> 10. Early coordination with the raih•oad company or light rail transit agency should occur-before tvorlc stalls. <br /> Option: <br /> 11. A flagger or a uniformed lain 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.
