The survey approach is often used in studying drivers' route choice behavior. Surveys enable the researcher to analyze the effects of traffic information directly from reported behavior and perceptions of the respondent. A large scale survey could achieve a sample size that adequately supports quantitative modeling and forecasting of route choice and traffic information use. A better representation of the population in a survey could also facilitate better understanding of actual drivers' behavior and decision processes. In this paper two innovative techniques in developing route choice surveys are introduced. The first is using computer-aided telephone interviews (CATI), and the second utilizes geographic information systems (GIS) capabilities.
