Quick Response Freight Manual: Final Report

Appendix K

Freight Transportation Data Sources

The key at the top of each page of this appendix categorizes the data in terms of perceived usefulness to the quick response freight modeling process. This is not meant to imply that data items categorized as "marginal" or "specialized" do not have very useful applications in other areas.

Appendix K is divided into four main parts related to their most appropriate application in the quick response freight modeling process:

• Part 1 -- Baselines, forecasts, and growth factors
• Part 2 -- Vehicle miles traveled (VMT) and networks
• Part 3 -- Survey development and other
• Part 4 -- Specialized data sources, organized as air, pipeline, rail, water, and multimodal and others.

TITLE: County Business Patterns
CONTENT: The County Business Patterns (CBP) is an annual series of state and national publications presenting county-level data on number of establishments, total employment, and payroll on an establishment basis, with economic activity classification reflecting the principal activity at each individual locations. The data are derived from a universe of employees covered by Federal Insurance Contributions Act (FICA). Data in the CBP represent the following types of employment covered by FICA: all covered wage and salary employment of private nonfarm employers and of nonprofit organizations; all employment of religious organizations covered under the elective provisions of FICA. Data for employees of establishments totally exempt from FICA are excluded. These include the following types of employment: self-employed, government, domestic service, agricultural, foreign, and railroad employment jointly covered by Social Security and railroad retirement programs. For activities such as construction, transportation, electric and gas, establishments are represented by those relatively permanent main or branch offices, terminals, stations, etc. Hence, the individual sites or systems of such dispersed activities (e.g., worksites) are not ordinarily considered to be establishments. Note: Data for industries with less than 100 employees in a given county are not shown in the printed reports, but are included on the CD-ROM and computer tape.

TITLE: Commodity Flow Survey: 1993
Abstract: The Commodity Flow Survey (CFS) is designed to provide data on the flow of goods and materials by mode of transport. The CFS is a continuation of statistics collected in the Commodity Transportation Survey from 1963 through 1977, and includes major improvements in methodology, sample size and scope. A sample of 200,000 domestic establishments randomly selected from a universe of about 900,000 establishments engaged in mining, manufacturing, wholesale, auxiliary establishments (warehouses) of multi-establishment companies, and some selected activities in retail and service was used. Each selected establishment will report a sample of approximately 30 outboard shipments for a two week period in each of the four calendar quarters of 1993. This will produce a total sample of about 20 million shipments. For each sampled shipment, zip code of origin and destination, 5-digit Standard Transportation Commodity Classification (STCC) code, weight, value, and modes of transport, will be provided. Check box information on whether the shipment was containerized, a hazardous material, or an export will also be obtained.
Source of Data: A sample of manufacturing wholesale establishments will complete questionnaire.

Significant Features and/or Limitations: The 1993 CFS will differ from previous surveys in greatly expanded coverage of intermodalism. Earlier surveys reported only the principal mode. The 1993 survey will report all modes used for the shipment (for-hire truck, private truck, rail, inland water, deep sea water, pipeline, air, parcel delivery or U.S. Postal Service, other mode, unknown). Route distance for each mode for each shipment will be imputed from a Mode-Distance Table developed by Oak Ridge National Laboratory. Distance, in turn, will be, used to compute ton-mileage by mode of transport.

TITLE: Employment and Earnings
CONTENT: The Employment and Earnings database contains information on industry employment, by state, and nationwide occupational employment. This data is published monthly.
METHODOLOGY: According to the BLS, Employment and Earnings (E&E) statistics are compiled from two places: household interviews and employer results. Data based on household interviews are obtained from the Current Population Survey (CPS), a sample survey of the population 16 years of age and over. The Bureau of Census conducts the survey each month for the BLS and provides comprehensive data on the employed and unemployed, including such characteristics as occupation, hours and industry. Data based on establishment records are compiled each month from questionnaires sent by the Bureau of Labor Statistics, in cooperation with state employment agencies. The Current Employment Statistics (CES) survey provides industry information on non-farm wage and salary employment, hours, and average weekly earnings. State agencies mail the questionnaires, then collect and compile data and make employment estimates at the state level. National employment estimates are then made by the BLS. The Employment and Earnings publication is prepared in the Office of Employment and Unemployment Statistics in collaboration with the Office of Publications and Special Studies.

TITLE: Occupational Employment Statistics
CONTENT: The Occupational Employment Statistics (OES) covers wage and salary employment by occupation for establishments in nonagricultural industries. The OES is an annual survey that provides employment by detailed occupation within detailed private industries, plus state and local governments.
METHODOLOGY: According to the BLS, the OES is a federal-state cooperative program. State employment agencies mail a BLS survey to a sample of about 250,000 employer units, the collect and compile the data. Employment estimates are based upon survey results adjusted to reflect total industry employment.

Abstract: The NHPN is a data base of the major highways in the U.S. It is a foundation for analytic studies of highway performance, vehicle routing and scheduling problems, and mapping purposes. The network is based on the U.S. Geological Survey's 1:2,000,000 digital line graphs (DLG's). The DLG's have been enhanced through addition of transportation attributes such as number of lanes, degree of access control, median type, and FHWA's functional classification codes. Other enhancements include the digitation of some additional links and the correction of topological errors to create a true analytic network.
