TIGER/Line Shapefile, 2023, County, Polk County, MO, Address Range-Feature Name Relationship File

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national filewith no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independentdata set, or they can be combined to cover the entire nation.
 The Address Range / Feature Name Relationship File (ADDRFN.dbf) contains a record for each address range / linear feature name relationship.  The purpose of this relationship file is to identify all street names associated with each address range.  An edge can have several feature names; an address range located on an edge can be associated with one or any combination of the available feature names (an address range can be linked to multiple feature names).  The address range is identified by the address range identifier (ARID) attribute that can be used to link to the Address Ranges Relationship File (ADDR.dbf).  The linear feature name is identified by the linear feature identifier (LINEARID) attribute that can be used to link to the Feature Names Relationship File (FEATNAMES.dbf).

 Linear Water Features includes single-line drainage water features and artificial path features that run through double-line drainage features such as rivers and streams, and serve as a linear representation of these features.  The artificial path features may correspond to those in the USGS National Hydrographic Dataset (NHD).  However, in many cases the features do not match NHD equivalent feature and will not carry the NHD metadata codes.  These features have a MAF/TIGER Feature Classification Code (MTFCC) beginning with an "H" to indicate the super class of Hydrographic Features.

The Address Ranges Relationship File (ADDR.dbf) contains the attributes of each address range.  Each address range applies to a single edge and has a unique address range identifier (ARID) value.  The edge to which an address range applies can be determined by linking the address range to the All Lines Shapefile (EDGES.shp) using the permanent topological edge identifier (TLID) attribute.  Multiple address ranges can apply to the same edge since an edge can have multiple address ranges.  Note that the most inclusive address range associated with each side of a street edge already appears in the All Lines Shapefile (EDGES.shp).  The TIGER/Line Files contain potential address ranges, not individual addresses.  The term "address range" refers to the collection of all possible structure numbers from the first structure number to the last structure number and all numbers of a specified parity in between along an edge side relative to the direction in which the edge is coded.  The address ranges in the TIGER/Line Files are potential ranges that include the full range of possible structure numbers even though the actual structures may not exist.

2023 NTD Annual Data - General Transit Feed Specification (GTFS) Weblinks

NOTE: As weblinks are updated continually by transit agencies, some links submitted in Report Year 2023 may no longer work. The most up-to-date weblinks dataset is refreshed on a monthly basis: https://data.transportation.gov/Public-Transit/General-Transit-Feed-Specification-Weblinks/2u7n-ub22/about_data

As of Report Year (RY) 2023, FTA requires that reporters with fixed route modes create and maintain a public domain general transit feed specification (GTFS) dataset that reflects their fixed route service. This specification allows for the mapping and other geospatial data visualization and analyses of key transit elements such as stops, routes, and trips. At least one GTFS weblink is provided by the transit agency for each fixed route bus mode and type of service. These include all Rail modes as well as Bus, Bus Rapid Transit, Commuter Bus, Ferryboat and Trolleybus.

GTFS requires that an overarching compressed file contain, at a minimum, seven underlying text files: (a) Agency; (b) Stops; (c) Routes; (d) Trips; (e) Stop Times; (f) Calendar or Calendar Dates.txt; and (g) Feed Info.txt. An eighth file, Shapes.txt, is an optional file. FTA collects and publishes these links for further analysis using related GTFS files. FTA is not responsible for managing the websites that host these files, and users with questions regarding the GTFS data are encouraged to contact the transit agency.

In many cases, publicly hosted weblinks could not be provided (i.e., due to constraints within the transit agency), but the agency was able to produce a zip file of the required GTFS data. Demand Response, Vanpool, and other non-fixed route modes are excluded. The column "Alternate Format" indicates that the agency provided FTA a weblink in an alternate format with some justification for doing so. The file "Waived" indicates that no GTFS files were produced and FTA granted the agency a waiver from the requirement in Report Year 2023.

NTD Data Tables organize and summarize data from the  2023 National Transit Database in a manner that is more useful for quick reference and summary analysis. This dataset is based on the 2023 General Transit Feed Specification database file.

If you have any other questions about this table, please contact the NTD Help Desk at NTDHelp@dot.gov.

TEAMER: New Technology Qualification for a Small-Scale Wave Energy Converter Powering Offshore Aquaculture

This dataset supports the concept verification of the Dual Inclined Paddles Wave Energy Converter (WEC), a small-scale marine hydrokinetic device developed by E-Wave Technologies LLC for offshore aquaculture applications. The review was conducted by the American Bureau of Shipping (ABS). The system consists of dual inclined paddles retrofitted to a buoy, connected to a tether-based power take-off (PTO) system. Verification was based on engineering analysis and 1:8 scale model testing at Stevens Institute of Technology. Included documents comprise a System Requirements and Description Document (SRDD), a risk assessment, and ABS review comments with responses. The documents define system architecture, performance criteria, environmental conditions, and applicable standards. The review is limited to concept verification and does not cover full-scale performance.

TEAMER: OpenFAST Modeling and Simulation of the Aquantis AQ10 Marine Hydrokinetic Turbine

This dataset was developed under TEAMER technical support (CRD-21-17763-0) to model the Aquantis AQ10, a spar buoy-based marine hydrokinetic turbine, using the OpenFAST simulation framework. The project transitioned modeling from the proprietary Tidal Bladed tool to OpenFAST to enable more flexible control strategy development and expanded physics-based capabilities. The dataset includes input files and simulation cases representing key dynamic behaviors such as added mass, wave loading, rotor-to-spar coupling, tower shadow effects, and a custom mooring system. The model supports integration with MATLAB/Simulink for controller implementation.  Also included is a post-access report detailing the modeling approach, validation results, and simulation findings from this work.

his work was funded by TEAMER RFTS 2 (request for technical support) program.

StingRAY Structural Optimization Final Technical Report Appendices

The protected data appendices to the public Final Technical Report. 

The overall project objective is to materially decrease the leveled cost of energy (LCOE) of the Columbia Power (CPower) StingRAY utility-scale wave energy converter (WEC). This will be achieved by reducing structural material and manufacturing costs and increasing energy output. In this Project, improving the overall Power-to-Weight ratio (PWR) is accomplished through lowering design margins?allowing for weight reduction and more efficient, cost-effective WEC manufacturing and assembly?and by optimizing mass-related WEC performance parameters, such as center of gravity and system inertia.

A mixed materials approach to further structural optimization was developed under this Project and validated with extensive laboratory structural testing. This approach substitutes fiber-reinforced plastic (FRP) for steel where appropriate. The benefits of steel are maintained where most useful, for instance at structural joints where the stiffness of steel is required, and the complex geometry is more readily fabricated with steel. However, there are structural spans whose simple shapes are readily fabricated with mandrel-wound FRP and where significant cost and weight savings can be found. An adhesive, double lap shear joint is used to join the FRP and steel subcomponents
