Advanced Search

This field searches all of the indexed fields in the RIP Database which include title, project description, notes, index terms, subject areas, project identifiers, project managers, principal investigators, funding agencies, and performing agencies.

Enter one or more terms from a title or the exact title to search on a project title.

Click the field or use the down arrow to select a Subject Area to limit search results by a specific transportation mode, function, or activity. You may also start typing to quickly filter the list, and then use the arrow keys or click on a term to select it. Multiple subject areas may be selected by repeating the process to select a term.

Enter complete or partial criteria to search for contract or grant numbers.

To search for multiple identifiers use OR to separate search terms.


Selecting project status checkboxes will limit your results to only those statuses.

Select from the drop down list to limit your search to a specific record source provider.

Click the field or use the down arrow to select a state to limit search results by one or more states. You may start typing to filter the list, and then use the arrow keys or cursor to make a selection. Multiple states may be selected.

Begin typing an index term. If the term is from the Transportation Research Thesaurus (TRT), matching terms will appear in a drop down list from which you can select terms. More than one term may be selected; in this case the default Boolean operator is OR.

Uncontrolled terms and ITRD Thesaurus terms do not appear in the drop down list but are still searchable in this field. To search uncontrolled terms or ITRD thesaurus terms, simply enter the terms on which you wish to search and press Enter.

To use Boolean logic and/or wildcards, simply enter the query without selecting any terms from the drop down list.

Enter a partial or complete organization name to search among funding organizations, performing organizations, and source organizations. You may use Boolean logic if needed.

Enter a person's last/family name and first/given name or initial to search among principal investigators and project managers. You can use wildcards and Boolean logic to search across all matching names, including first names.

Note that a query for Smith, R* will return results for 'Smith, Robert,' 'Smith, Richard' and authors 'Smith and Robert' or other last/family and first/given names that begin with the letter R. It will not return results for 'Smith, Bob'. Please keep in mind that due to differences in indexing practices among the various contributors to the TRID Database, some records contain only first/given initials rather than full names.

Select Date Range

The default is set to search all dates. To narrow your search, enter a start and end date, or select one of the presets.

The range entered in the From and To fields limits results based on the option selected in the Date Range Type field, which can be set to search project start date, project end date, or system created date.

Use YYYY or YYYYMM as the date format.

Date Range Type

Use these parameters to change the order in which results are displayed.

The Status sort by option sorts results by project status alphabetically, i.e.: ACtive, COmpleted, INactive, ProGrammed, PRoposed, and TErminated.

This sort option is more useful if you use it in conjunction with the project status field to limit results to two or three statuses.

Sort Order

Select the number of results shown on each page.
