Abstract

During the past two years the Driving Research Laboratory at Iowa State College has been using return postcards to obtain data on certain aspects of driving and driver's habits. Since the return of the postcards has a definite effect on the value of the survey an effort has been made to determine how the percentage returned may be increased. The first use of the postcard described here was in connection with a traffic survey. The problem was to determine the hourly use of the roads by age and sex. The procedure set up has been for an observer to estimate the age and record the sex of the driver as the vehicle passes a selected observation point. In an effort to verify the observed information a double postcard was sent to the owner of the vehicle which passed. Names and addresses of the owners were obtained from the State automobile license files. On the return postcard the owner was requested to state the age and sex of the driver, the number of persons in the car, and the number of miles driven by that driver the hour of the day he was observed.
