1 D11 - ENGINEERING DIVISION

2 VISIBILTY DURABILITY COST

3 Traffic Signs and Stripes are one of the Most Cost-effective Means of Improving Highway Safety The Cost of Traffic Sign Panels and Stripes is Minimal Compared to the Total Project Cost < 4%

5 PAINT STRIPES D-11 has 4,000 lane miles Up until 2010 District 11 used paint stripes Paint Life Expectancy < 1 Year To maintain visibility Caltrans MTCE crew had to refresh the paint stripes on a yearly basis Total Yearly Cost = $3,000,000 million Issues: Safety + Labor Cost + Material Cost

6 THERMOPLASTIC STRIPES In 2009 we Started Experimenting with THERMOPLASTIC STRIPES HEATED-PLASTIC & REFLECTIVE BEADS Layer #1 heated thermo, degrees Layer #2 Glass beads on top of the thermo

7 THERMOPLASTIC STRIPES THERMOPLASTIC CLOSE-UP VIEW

8 THERMOPLASTIC STRIPES THERMOPLASTIC TRUCK

9 THERMOPLASTIC STRIPES SPRAY NOZZLES

10 THERMOPLASTIC STRIPES D-11 Started Experimenting 2009 Reflectivity Value: White = 250 Yellow = 150 COST PER YEAR OF SERVICE $ COST/LF LIFE EXPECTANCY YEARS COST PER YEAR OF SERVICE Paint$0.181 Thermoplastic$0.314$0.08 IN 2010 DISTRICT-11 SWITCHED STRIPES ALL THERMO IN 2010 DISTRICT-11 SWITCHED STRIPES ALL THERMO

11 HIGH REFLECTIVE THERMOPLASTIC STRIPES

12 D-11 Started Experimenting 2011 Layer #1 Heated Thermoplastic Material Layer #2 Highly Reflective Glass Beads Layer #3 Standard Glass Beads Cost $/LF in 2011 = $0.42 Cost $/LF in 2014 = $0.32

13 FINAL PRODUCT CLOSE-UP

14 HIGH REFLECTIVE BEADS DRY BEADS CLOSE-UP COIN (DIME) STANDARD BEADS

15 DRY BEADS CLOSE-UP HIGH REFLECTIVE BEADS STANDARD BEADS

16 FINAL PRODUCT ENHANCED THERMO

18 RETROREFLECTIVITY IN (MCDM-2LX-1) YELLOW STRIPES RETROREFLECTIVITY COMPARISON WHITE STRIPES 3X RETROREFLECTIVITY

19 RETROREFLECTIVITY COMPARISON

20 HIGH PERFORMANCE THERMOPLASTIC HAS: DISTRICT-11 IS CURRENTLY USING ENHANCED THERMOPLASTIC ON ALL NEW PROJECTS D11 - STRIPING CONCLUSION Standard Thermo Vs High Performance Thermo ALMOST THE SAME COST 3X TIMES THE RETROREFLECTIVITY HIGH VISIBILITY DURING DRY & WET WEATHER IN 2012 D-11 SWITCHED STRIPES TO ALL HIGH REFLECTIVE THERMO IN 2012 D-11 SWITCHED STRIPES TO ALL HIGH REFLECTIVE THERMO

21 WHAT IS NEXT IN FOR STRIPING?

22 Reflectivity Durability Cost

23 RETROREFLECTIVE SHEETING TYPES WHICH TYPE SHOULD WE USE?

24 RETROREFLECTIVITY Retroreflectivity is defined as the light that returns to the light source

26 CAR HEADLIGHTS OFF (Location 1)

27 CAR HEADLIGHTS ON (Location 1)

28 CAR HEADLIGHTS OFF (Location 2)

29 CAR HEADLIGHTS ON (Location 2)

30 CAR HEADLIGHTS OFF (Location 3)

31 CAR HEADLIGHTS ON (Location 3)

32 CAR HEADLIGHTS OFF (Location 4)

33 CAR HEADLIGHTS ON (Location 4)

34 RETROREFLECTIVITY / WARRANTY

35 D-11 REPORT

36 REDUCE INFRASTRUCTURE COST REDUCE ELECTRICAL ENERGY COST INCREASE SAFETY REDUCE MAINTENANCE COST (Bulbs, Copper Theft) SAVINGS & BENEFITS - TYPE XI “2015 LIGHTS OUT” IN 2012 D-11 SWITCHED TO TYPE XI SHEETING FOR ALL SIGNS IN 2012 D-11 SWITCHED TO TYPE XI SHEETING FOR ALL SIGNS

37 JULY TYPE XI SHEETING STATEWIDE STANDARD FOR GUIDE SIGNS TYPE XI SHEETING A STATEWIDE STANDARD

38 OTHERS REASONS FOR BETTER & BRIGHTER SIGNING & STRIPING MATERIALS

39 MUTCD MINIMUM MAINTAINED RETROREFLECTIVITY LEVELS REPLACE NON-COMPLIANT WARNING AND REGULATORY SIGNS 2015 REPLACE GUIDANCE AND STREET NAME SIGNS 2018 MANUAL ON UNIFORM TRAFFIC CONTROL DEVICES

40 NOW MORE THAN EVER WE NEED BRIGHTER SIGNING & STRIPING ELDERLY BABY BOOMERS POPULATION IS GROWING

41 GROWING DRIVING POPULATION
