Figure 3. LTPP data collection and data movement flowchart.
Flowchart. This figure presents the following information:
Deflection data collected with falling weight deflectometer (FWD):
- Field control
- Data files sent to Regional Offices
- QC using FWD SCAN. Data may be edited
- Data loaded into RIMS
Longitudinal profile collected with profilometer:
- Field control by checking on International Roughness Index (IRI) variability
- Data files sent to Regional Offices
- PROFCHK: recompute profile parameters and QC
- Some profiles may be eliminated, then data is loaded into the RIMS
Transverse profile data by dipstick:
- QC using PROFCHK by the regions
- Some profiles may be eliminated
- Data loaded into the RIMS
Transverse profile data with film:
- Data analyzed and electronically stored
- Data files sent to Regional Offices
- Data loaded into the RIMS
Distress data:
- If it is manually collected, then review and enter data by Regional Offices, and data is loaded into RIMS
- If it is photographically collected, then data files are sent to Regional Offices, and data is loaded into RIMS
Climatic data collected at automated weather station (AWS):
- Data downloaded by modem or during site visit
- AWS check to review the data
- Data checked and extracted
- Data loaded into RIMS
Traffic data collected by weigh-in-motion (WIM) and automated vehicle classification (AVC):
- Data entered into Regional Traffic Database
- Perform QC and flag data
- All data entered into the Central Traffic Database
- Acceptable data used to compute summary statistics
- Data loaded into the RIMS
Materials data field and laboratory tests (coring and sampling):
- Testing by LTPP and testing by State agencies
- Test data/forms forwarded to Regional Offices
- Review and convert data into machine readable form
- Data loaded into the RIMS
Materials data field and laboratory tests (in situ field testing):
- Test data/forms forwarded to Regional Offices
- Review and convert data into machine readable form
- Data loaded into the RIMS
Data Loaded into RIMS:
- Series of data-specific QC programs executed on data files
- Manual data upgrades by Regions if appropriate
- Data uploaded into IMS Database (National)
- Level E Data release to public
