  2. Purpose of the Course To train personnel who may be required to assist motorists and emergency personnel within the highway right-of-way, as part of their Road Ranger Duties. Module 10

  3. Objectives of the Course • To familiarize Road Ranger participants with the concepts and terminology of setting up a work zone in emergency situations. • To gain knowledge and understanding of the equipment, techniques and Procedures necessary for the Road Rangers to safely maintain traffic flow using standards from the MUTCD and DS 600 Series Indexes. • To upgrade the performance of personnel establishing work zones on State and Federal highways. Module 10

  4. Follow • All WZTC operations and devices must conform to: • Manual on Uniform Traffic Control Devices for streets and highways (MUTCD) • Design Standards (DS) Module 10

  5. Basic Safety Principles • Traffic safety in temporary traffic control areas should be an integral and high-priority element of every project from planning through design and construction. • Traffic movement should inhibit as little as possible. • Drivers and pedestrians should be guided in a clear and positive manner while approaching and traversing the temporary traffic control zone. Module 10

  6. Basic Safety Principles • To ensure acceptable levels of operation, routine inspection of traffic control devices. • To maintain a good message with the motoring public, upgrade MOT when materials become availably during the life of the temporary traffic control zone. Module 10

  7. Basic Safety Principles • The control of traffic in an emergency situation is an essential so all agencies can do their part to open the roads to the motoring public quickly and safely • Maintaining good public relations is necessary. Module 10

  8. What can we expect Module 10

  9. Basic Requirements for Traffic Control Devices • Fulfill a need • Command attention • Convey a clear, simple meaning • Command respect of road users • Give adequate time for proper response Module 10

  10. Qualified Product List • Only approved traffic control devices that are listed on the QPL may be used. • Approval number shall be engraved on the device in a visible location. • Water – resistant labels may be used Module 10

  11. Function of Traffic Control Devices • To warn and alert drivers of hazards created by work zone activities. • To guide and direct drivers and pedestrians safely past the hazards. Module 10

  12. Placement • Channelizing devices must be placed to provide a smooth and gradual transition in moving traffic through the work zone Module 10

  13. TRAFFIC CONES and TUBULAR MARKERS • COLOR - Orange shall be the predominant color and should be kept bright and clean for maximum target value. • USE - Cones and tubular markers are applicable for daytime use. For nighttime use, cones must be reflectorized. Module 10

  14. Traffic Cones Module 10

  15. Cone Spacing • Maximum spacing between cones shall be 25 feet (8 paces) Module 10

  16. Cones • Only used when workers are present • Not to exceed 2 miles or a 12 hour work period • One person to maintain them • Reflective collars when used at night Module 10

  17. Arrow Panels • USE - Intended to supplement other warning devices. • Provide additional advance warning • Used for lane closures on high-speed, high volume multi-lane roadways. • Left indication shall never be displayed on a lane closure on a two-lane, two-way highway. Only CAUTION mode(s) will be used on these types of highways. Module 10

  18. Arrow Panels MODES • PASS LEFT • PASS RIGHT • PASS EITHER SIDE • CAUTION Module 10

  19. Arrow Panels Size: Panel TypeMinimum Size (inches) Type A 48 X 24 Type B 60 X 30 Type C 96 X 48 Type D Must conform to an arrow Type A: For use on low-speed urban streets Type B: For intermediate-speed facilities and for maintenance operations on high speed roadways. Type C: Intended to be used on high-speed, high volume traffic control projects. Module 10

  20. Arrow Panels • Nighttime Use - When Advance Warning Arrow Panels are used at night, the intensity of the flashers shall be reduced. • Location - For lane closures on multi-lane roadways, an arrow panel should be located on the shoulder at the beginning of the taper. An alternate location is centered in the closed lane behind the taper channelizing devices near the beginning of the taper - if shoulder space is not available. Module 10

  21. Intensity(Arrow Board Brightness) • High intensity during the day • Low intensity during the night Module 10

  22. Warning Signs Module 10

  23. Guide Signs Guide signs generally have a rectangular shape with the long dimension horizontal. The basic color for guide signs iswhite on green. At work zones , guide signs may be black on orange to indicate routing changes due to the maintenance activity. Information signs which relate to the work being done and detour route are black legend on an orange background. Module 10

  29. TRAFFIC CONTROL OPERATION • Operations in response to emergencies, varies according to the nature, duration, location of work, type of roadway, speed of traffic, and the potential hazards • Upgrade MOT when material becomes available during the life of the temporary traffic control zone Module 10

  30. Units of Measurement • ODOMETER: • 1/10 of a mile on the odometer equals 500 feet (actual 528). This provides a safety margin of 28 feet each 1/10 of a mile. • REFLECTIVE PAVEMENT MARKERS [RPM]: • Presently spaced 40 feet apart. • Skip Strip - 40 feet from start to start Module 10
