Transportation Research Record 1477 contains the following papers: Stated preference survey for calculating values of time of road freight transport in France (Wynter, LM); Survey methodology for collecting freight truck and destination data (Casavant, KL, Gillis, WR, Blankenship, D and Howard, C); Design and implementation of a statewide roadside origin-destination survey in Vermont (Virkud, U and Keyes, CS); Design and conduct of a statewide household travel survey in Vermont (Crevo, CC, Niedowski, RS and Scott, DJ); Traffic data collection using video-based systems (Bonneson, JA and Fitts, JW); Development of a prototype traffic safety geographic information system (Kim, K, Levine, N and Nitz, L); changes in the direction of urban travel for the Chicago area, 1970 to 1990 (Christopher, EJ, Rogus, M and Soot, S); analysis and use of 1990 census transportation planning package in Delaware Valley Region (Zakaria, T); Estimation of pass-by trips using a license plate survey (Dey, SS and Fricker, JD).

This synthesis will be of interest to planning, administrative, and traffic officials in state transportation agencies and in metropolitan planning organizations (MPOs); to consultants concerned with the design and conduct of surveys; and to those engaged in developing and applying travel forecasting models. It describes the various facets of planning, designing, conducting, and evaluating household travel surveys. This report of the Transportation Research Board provides information on the manner in which many household surveys are currently carried out and provides comment on the likely changes in the process, in the survey instrument, and in the application of more cost-effective methods of data collection in household travel surveys. This synthesis describes the methods for collection, including survey instrument design, as well as testing and administering the surveys. Information on time and cost requirements is also included, as are descriptions of evaluation and data analysis methods.

This report identifies the types and sources of person travel data likely to be used for statewide transportation planning and presents procedures for developing sampling plans and survey designs for conducting travel surveys to collect the required travel information. Sampling concepts, formulas, and survey administration guidelines are documented for conducting statewide and regional household travel surveys, intercity modal passenger surveys, and roadside surveys. Both cross- sectional and seasonal survey designs are evaluated. Procedures are presented for estimating required sample sizes for alternative types of survey estimates of interest in statewide transportation planning. The application of these procedures is illustrated using "real world" sampling problems. The influence of alternative levels of precision on sample size requirements is presented in the report.
