Using Data Collection Year instead of Data Reporting Year
Data Collection Year vs. Data Reporting Year for the Non-Safety Measures
The data points in the line graphs and tables for the non-safety performance measures represent the condition/performance at the time the data was collected, not reported. FHWA displays the collection year instead of the reporting year so it is clear which year the condition/performance represents. See the table below for an example of this process for the actual condition/performance data included in the 2018 Biennial Report.
| Measure Area | Data Collection Year(s) |
Metric Data Reporting Year | What does the 2017 data point in the graphs and tables represent? |
|---|---|---|---|
| Non-Interstate NHS Pavement Condition | 2016/2017 | Reported to HPMS in 2018 | Represents the condition in 2017. |
| Bridge Condition | Bridge inspection cycle through March 2018 | Reported to NBI in March 2018 | Represents the condition in 2017. |
