5 Basic Safety Principles Traffic safety in temporary traffic control areas should be an integral and highpriority 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 5

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 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 11

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

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

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 16

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 17

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

19 Size: Panel Type Minimum Size (inches) Type A 48 X 24 Type B 60 X 30 Type C 96 X 48 Type D Arrow Panels 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 19

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 20

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

22 Warning Signs Module 10 22

23 Guide Signs Guide signs generally have a rectangular shape with the long dimension horizontal. The basic color for guide signs is white on green.
