Find Sections

Under the ‘Find Sections’ panel, there are a number of filters that can assist you in narrowing down your search for LTPP sections. These include general information, structure, climate, traffic, and performance filters. Hovering mouse over each filter will display a description that explains how each filter works. For example, you can find sections that are more than 25 years old using the Age filter.

Filter Menu

In the “Find Sections” panel bar, you will see different options under filter menu. If you filter your search criteria using “Find Sections,” you can save your filters by clicking on the “Save Filters” option in the “Filter Menu”. When you click on the “Save Filters” menu option, a new window will appear asking you to name your set of filters.

You can then open the saved filters by clicking on the “Open Filters” option in the “Filter Menu.” When you open a saved set of filters, InfoPave will automatically apply your saved filters.

Section Information Bar

Section information bar shows the number of selected sections which have been filtered using the “Find Sections” panel. Other available options are “Show Sections” and “Go To…”. By selecting Show Sections button, you can view the list of your selected sections and corresponding general information for the selected section.

The “Go To…” feature provides quick way of navigating to other InfoPave features such as Maps, Section Summary Report, Section Timeline, Pavement Cross-Section Viewer etc. For example, by switching to Map feature you can locate the sections on a map or visualize data to make sure you have selected the sections of your choice.

Data Classification

After finding your desired sections, you can select your required data nodes under Structure, Climate, Traffic, and Performance categories. This data classification is organized according to primary and advanced data. The legend key on top, describes the type of data classification.

This area also provides options to pick and choose data fields of your choice.

In addition, you can see the count of sections for which the selected table contains data. This allows you to know if the data is available for all selected sections.

The ‘Selected Data’ panel at the bottom of your screen will contain all of the selected data tables, number of selected sections, number of available data records, and number of data attributes or fields.

You may edit or remove each item until you are satisfied with your selection. Then you can add the selected data to your data bucket.
