8. INTERFERENCE AND ENVIRONMENTAL INFLUENCE

A. Measurements made with the MRU may be adversely affected by moisture in the air and on the surface of the pavement markings. Standing water, dew, sleet, and snow on the surface of the pavement marking or fog and smoke in the air decrease the amount of retroreflected luminance due to light reflecting off the water and away from the detector. Environmental factors are difficult to measure and may vary dramatically; therefore, testing must be avoided when these conditions are present.

B. Measurements made with the MRU may be adversely affected by surface dirt, debris, and contamination on the pavement marking, which decreases the amount of retroreflected luminance. This may cause variability in the retroreflected luminance of the pavement marking and must be noted accordingly. The operator must note when these conditions are present. See Section 9 – EVENT CODES for additional information.

C. Background noise from roadway surfaces and high retroreflectivity levels of Raised Pavement Markings (RPMs) can influence the retroreflected luminance of the pavement markings. The operator must recognize these issues if the data acquisition system is not working properly, so that appropriate corrective actions can be applied.

D. The MRU contains advanced optical and electronic components that are sensitive to temperature fluctuations. To ensure optimal performance, it is recommended to maintain a stable internal temperature within ±2°C of 25°C. If this temperature range cannot be maintained, corrective actions must be taken as per the manufacturer's guidelines. It is essential to understand and implement these corrective measures if the optical or electronic components are not functioning properly or as intended.

Exhibit A

9. EVENT CODES

A. For roadway events, use the standard nomenclature and data acquisition event codes, as shown in Table 3. The roadway events must be recorded to the nearest thousandth of a mile. It should be noted that, except for triggered events, the data should remain in exact 1/10th mile increments.

(i.e., if an event is flagged at mile point 1.555 with ascending mile points, regardless of whether it is part of the “Reset Data” or “Hold Event” data, the preceding and following mile points should be 1.5 and 1.6, respectively.

B. The following items describe how the events must be processed.

1. Reset Data – When triggering a roadway event (pavement change, audible, etc.), the data acquisition system must end the current row of data analysis to the nearest thousandth while beginning a new row of data analysis.

2. Hold Event – The data acquisition system must hold the event code while continuing data analysis until the event is triggered a second time for roadway conditions (bridges, turn lane, construction, etc.)

3. Stop Collection – The data acquisition system shall automatically halt data collection whenever conditions may result in an inaccurate representation of pavement markings.

10. ACCEPTANCE CRITERIA FOR MOBILE RETROREFLECTIVITY UNITS

10.1 VISUAL INSPECTION

Visual inspection is the first step in making sure the MRU is ready for operation. A good practice to ensure the equipment is test-ready is to inspect that all brackets, mounts, and bolts are tight and mounted securely around the exterior of the equipment before calibration and routine operation.

The retroreflectometer window shall be inspected to ensure it is clean and free of any damage or debris.

Following the inspection of external components, the MRU shall be powered on. The calibration panel must be checked for signs of damage or wear. The MRU operator shall then perform the calibration procedure, which must be reviewed to verify accuracy and correct geometry. The retroreflectometer’ s laser power intensity and laser profile shall be measured to ensure readings fall within acceptable limits. Arc-like or parabolic distortions must be avoided to prevent data collection errors. For a 3.28-foot scan, the longitudinal variation of the laser path shall not exceed

3.28 feet. This visual inspection of the MRU shall be performed monthly or as needed.

10.2 CALIBRATION

The MRU calibration equipment should be verified and standardized by the manufacturer at least once a year for

• ALIGNMENT AND WANDER

• LATERAL WANDER

• LONGITUDINAL WANDER

10.3 BACKGROUND NOISE TESTING

Background Noise Testing is performed to ensure that the noise from the environment and other reflective materials are not influencing the RL values.

10.4 COMPARISON TESTING WITH HANDHELD RETROREFLECTOMETERS

To determine if the RL values measured using the MRU are comparable to those from conventional handheld retroreflectometer, a total of six panels (3 white and 3 yellow) with RL values ranging between 100 and 1,000 mcd/m2/lux will be tested. After the MRU has been calibrated, the RL of all six panels will be measured with the MRU, one at a time. The RL from the MRU shall be within ±15.0% of the handheld RL values. The background noise will be monitored during this test to see if different panels affect the background noise. The comparison tests shall be conducted once every two months or as deemed necessary.

Exhibit A

10.5 FIELD TESTING

The following field tests will be conducted to verify the performance of the MRU, operator, and data collection software:

1. Distance Measuring Instrument (DMI) Accuracy

2. Precision Testing

3. Retroreflective Stability and Temperature Test

4. Retroreflective Stability and Speed Test

5. Operational Competency Test

10.6 DISTANCE MEASURING INSTRUMENT (DMI) ACCURACY

The MRU must be equipped with a distance measuring instrument (DMI) to measure the distance traveled by the vehicle. The DMI distance must be within ±5.280 feet (0.1%) when measuring a 1.0-mile section of roadway. The DMI shall be calibrated monthly or as required at locations designated by Caltrans. Additionally, recalibration must be performed whenever tires are changed, rotated, or their air pressure is adjusted.

10.7 RETROREFLECTIVE STABILITY AND TEMPERATURE TEST

Testing for stability with a temperature change is recommended before using an MRU on actual projects.

10.8 RETROREFLECTIVE STABILITY AND SPEED TEST

MRU testing is conducted at Posted Roadway Speeds, so it is important to verify the MRU results are not affected by vehicle speed.

10.9 OPERATIONAL COMPETENCY TEST

Additional field tests will be conducted to evaluate the following factors:

a. Proper use of event codes such as pavement changes, construction, no stripe line, etc.

b. Daytime and nighttime testing

c. Driver competency (e.g., vehicle wander)

d. Proper identification of stripes

e. Ability to set RL thresholds for the Raised Pavement Markings (RPM)

f. Proper handling of MRU during acceleration, braking, and stopping

For these tests, the MRU will be mounted on either side or the front of the vehicle. Tests shall be conducted on roadways with various pavement types and markings selected by Caltrans to include the following:

• Stripe colors - Yellow and white

• Stripe patterns - Single solid, single skip, double solid, left solid/right skip, left skip/right solid, and edge line.

• Various ranges of retroreflectivity

These additional tests shall be conducted yearly or as deemed necessary.

Exhibit A

10.10 QUALITY ASSURANCE

Before providing MRU services to Caltrans, the contractor must demonstrate that their MRU and operator satisfy all the quality assurance criteria described above. To provide MRU services, the contractor must conduct the quality assurance tests at the frequency designated for each respective test. Anytime a quality assurance criterion is not met, the contractor must inform Caltrans and take remedial action. The contractor must notify Caltrans once remedial actions have been implemented and subsequently demonstrate that all quality assurance criteria are met.

Caltrans will determine which quality assurance tests need to be repeated after reviewing the issue and the contractor’s corrective measures.

Caltrans reserves the right to perform initial inspections to verify that the contractor has provided accurate data and a quality product. These initial checks will occur at the start of the contract and periodically thereafter to ensure data is submitted in the required format and condition. Ongoing data reviews will also be conducted to confirm that all submitted files meet acceptance criteria.

Furthermore, Caltrans will examine both summary and raw data files to verify that proper settings and data collection procedures are being followed.
