The Keyword field can be searched by itself from the RIP Home page or Additional Search Filters form, or in combination with any/all other available text fields and limits in the Additional Search Filters.
Searching the Keyword field from either the home page or in the Additional Search Filters includes all of the indexed fields in RIP: title, project description, notes, index terms, subject areas, contract or grant numbers, record accession numbers, project managers, principal investigators, sponsor organizations, managing organizations, and performing organizations.
RIP works best with Boolean (AND, OR, NOT) logic. See the section below on Advanced Search Tips for a more detailed explanation and search examples.
These rules apply to any plain text field on the Additional Search Filters form. Plain text fields include: Keywords; Title; Contract or Grant Numbers; Organization; Person.
- Entering terms in multiple fields searches for all terms in the query.
- For an exact match, enclose a phrase within quotes:
- For a wild-card search, use an asterisk (*) after a partial word.
- RIP will perform limited automatic stem searching when using quoted phrase searches.
- For a Boolean search, use
NOTbetween words or phrases. See more information about using Boolean logic.
- A nested search may be performed by enclosing term(s) within parentheses.
- Stop Words: The following words are ignored in any search or quoted phrase in order to reduce the size of the search index and increase search speed:
about, also, an, and, another, any, are, as, at, be, because, been, being, between, both, but, by, came, can, come, could, did, do, does, each, else, for, from, get, got, has, had, he, have, her, here, him, himself, his, how, if, in, into, is, it, like, make, many, me, might, more, most, much, must, my, never, now, of, on, only, or, other, our, out, over, same, see, should, since, so, some, still, such, take, than, that, the, their, them, then, there, these, they, this, those, to, too, want, was, we, well, were, what, when, where, which, while, who, will, with, would, your.

Available Search Fields
This field searches all of the indexed fields in RIP which include title, project description, notes, index terms, subject areas, contract numbers, project managers, principal investigators, sponsor organizations, managing organizations, and performing organizations.
Enter one or more terms from a title or the exact title to search.
- This field searches project titles.
will retrieve any record that has either of these two words anywhere in the title. Adding the asterisk to the end of the word pandemic will also retrieve “pandemics.”
This field can be a very effective way to narrow or focus your searches. If you are interested in runway pavements, selecting Aviation will effectively exclude results about highway pavements, for example. Most records in RIP have at least one mode, and at least one function.
- If you select multiple subject areas, you can switch between
ANDBoolean logic for your selections by switching the toggle button directly below the field between: Match Any Subject Listed or Match All Subjects Listed.
- Click in the field and use the down arrow or scroll button on your mouse to select your subject(s). On a smartphone, you’ll see a standard scroll wheel from which you can easily select multiple terms. You may also start typing to filter the list, then use the arrow keys or highlight with the cursor to select a subject area. Multiple subject areas may be selected in the same manner.
There are 37 Subject Areas available:
- 11 modes: Aviation; Freight Transportation; Highways; Marine Transportation; Motor Carriers; Passenger Transportation; Pedestrians and Bicyclists; Pipelines; Public Transportation; Railroads; Transportation (General)
- 26 functions: Administration and Management; Bridges and other Structures; Construction; Data and Information Technology; Design; Economics; Education and Training; Energy; Environment; Finance; Geotechnology; History; Hydraulics and Hydrology; Law; Maintenance and Preservation; Materials; Operations and Traffic Management; Pavements; Planning and Forecasting; Policy; Research; Safety and Human Factors; Security and Emergencies; Society; Terminals and Facilities; Vehicles and Equipment
Many projects include unique identifiers which are frequently alphanumeric, containing some combination of numbers and letters.
Enter complete or partial terms to search for contract or grant numbers.Add an asterisk to the end of a partial number to search for numbers starting with that string . For example, “69A355*” will retrieve “69A3551847103” and “69A3551747115.” However, it will not retrieve “69A-3-55” because of the dashes.
To search for multiple terms, use
OR to separate search terms.
Many projects move through a regular lifecycle, from proposal to completion/termination. The six status categories in RIP are listed in alphabetical order:
- Ongoing research project
- Project has been finished and closed
- Project temporarily suspended due to a funding or other interruption
- Sponsor has approved/allocated funding for the project, but the research is not yet underway
- The project is being considered, but has not yet been funded and/or approved
- Project was terminated before completion
Click the checkbox before any Status, or choose . The default is all Status categories.
A source is the organization or type of organization that provided the records to the RIP Database. Only one Source can be selected per search. If you need to limit your search to two or more Sources, repeat your search while selecting the appropriate Source, then use the Search History feature to combine those searches using the
OR Boolean operator.
- TRB – limits to TRB projects, including those managed by the Cooperative Research Programs.
- UTC – (University Transportation Center) limits to projects from the University Transportation Centers (UTC) Program, which is funded by the US Department of Transportation.
- USDOT – (US Federal Department of Transportation) limits to projects funded, sponsored or conducted by the US Department of Transportation or one of its agencies.
- STATEDOT – (US State Departments of Transportation) limits to projects funded, sponsored or conducted by state-level departments of transportation in the United States.
Use the Location filter to limit a search by the state in which a Source Agency, Sponsoring Organization, Managing Organization or Performing Organization is based. Click the field and scroll to select one or more states. Start typing to filter the list, then use the cursor to make a selection. Multiple states may be selected.
Index terms are terms from the Transportation Research Thesaurus (TRT). Begin typing an index term. Matching terms will appear in a drop-down list from which you can select terms. Best matches will appear first. Results will include non-preferred terms that have been assigned to the preferred TRT term.
More than one term may be selected. The default Boolean operator is
OR. You can switch between
AND Boolean logic for your selections by switching the toggle button directly below the field between: Match Any Term Listed or Match All Terms Listed.
For more complex searches use the Search History feature to combine those searches using the
NOT Boolean operators.
Non-TRT terms do not appear in the drop-down list but are still searchable in the Keywords field and Partial Index Term field.
This field searches all Index Terms including:
- Transportation Research Thesaurus (TRT) terms
- Geographic Terms (A specific place or geographic feature described in the project)
- Identifier Terms (A specific entity, structure or organization that is a important element of the project)
It also allows a user to employ Boolean (
NOT) logic. See Advanced Search Tips above for examples.
Enter a partial or complete organization name to search among sponsor organizations, managing organizations, performing organizations, or source agency. You may need to use Boolean logic.
- For example, will return records for projects in which Maine Department of Transportation is a sponsor organization, managing organization, performing organization or source agency.
- will also bring back records in which Maine Department of Transportation is a sponsor/performing/managing/source organization, but also records with University of Maine.
Enter a person's last/family name and first/given name or initial to search among project managers and principal investigators. You can use wildcards and Boolean logic to search across all matching names, including first names.
Note that a query for 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 RIP Database, some records contain only first/given initials rather than full names.
The default is set to search all dates. To narrow your search, select one of the preset buttons: , , , or use to specify a date range.
The default is set to search on the date that a project started or will start.
Select Record Created Date to search by date on which records were initially entered into the Database.
Select Project End Date to search by date on which the project was completed or is expected to be completed.
