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
|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.|
|System Reliability||2017||Reported to HPMS in 2018||Represents the condition in 2017.|
|Freight||2017||Reported to HPMS in 2018||Represents the condition in 2017.|
