When the Sign Rec # is selected these attributes are automatically filled out from the Sign Inventory record. Some of this information is used to perform calculations for the retroreflectivity test. |
Background RR |
The retroreflectivity score for the background of the sign. |
Legend RR |
The retroreflectivity score for the legend of the sign. |
Reflectivity Pass |
Indicates whether the sign passes the retroreflectivity test. This judgment is based on test calculations illustrated below. If the check box is marked, the sign passed; if blank, the sign failed. |
Lock Value |
When this box is checked, the Reflectivity Pass field is locked. Therefore, the system does not perform test calculations, and the user is able to manually mark whether the sign passed or failed. |
Reflectivity Pass Field Calculations
The logic behind the calculations for retroreflectivity testing come from the Manual of Uniform Traffic Control Devices.
