A mail survey of randomly selected carriers was used to collect data about freight flows on Arizona's primary and secondary highways and about carriers' perceptions of certain freight related problems. The data obtained included commodities shipped, tonnage, origins and destinations, Arizona routes used in the travel, and attitudinal information on several transportation issues and concerns. The route-specific freight flow information was needed to run a simulation model that had been developed for the Arizona Department Transportation. The sample was drawn as a three-stage stratified random sample of 2,100 carriers from a prepared list of population of 12,900 carriers (16.28 percent sample size). The rationale for using the mail survey technique, the design of survey forms, the procedures used in follow-up, and the various strategies adopted to achieve better response rate are described. A summary of some of the data analysis results is given. The survey results indicate that Interstate highways are the routes most used for freight movements in Arizona. Furthermore, the attitudinal questions revealed that carriers consider insurance costs to be their major future concern and pavement condition to be the most significant problem that may affect the trucking industry.
