COMPUTER-BASED PERSONAL INTERVIEWS: A PRACTICAL TOOL FOR COMPLEX TRAVEL SURVEYS

This report describes the use of computer based interviewing in a recent survey carried out for British Rail during October 1988 to March 1990 on a sample of over 1000 people. A number of practical aspects of the design and administration of the survey are presented including new forms of customisation and adaptation of stated preference experiments. An assessment of the use of the computer based interviewing technique is also presented as are some conclusions about its future application. The project involved a study of interurban travel whose objective was to estimate the elasticities of demand for long distance travel with respect to fares in 2 distinct markets: a) leisure travel; and b) the railcard market. For leisure travel, interviewees were asked a number of questions about a) their method of travel and its cost; b) their perception of the characteristics of the most likely travel option if rail was not available. A stated preference exercise was also carried out which made use of the journey information and the transfer price information in order to customise the design of the exercise to reflect the specific circumstances of each respondent. Computer based interviewing was very well received by respondents, and had many advantages. These more than outweighed the extra costs of programming and equipment hire.
