PROCESSING, ANALYSIS, AND ARCHIVING OF TRAVEL SURVEY DATA

摘要

The definition of quality standards and some forms of guidance are also appropriate as a supplement in the steps of data processing, analysis, documentation, and archiving of travel surveys. Analysis of the state of the art indicates that knowledge is well developed, even though some questions need further research. However, this knowledge is distributed among different sources and needs to be put together and standardised in an appropriate way. The definition of a minimum common denominator of standards for data processing and analysis would help to raise the data and output quality. For the definition of quality standards, it is also very important to take into account the cost-benefit ratio between the effort needed to achieve a defined quality of results and the quality level itself. Although this question has been well analysed for surveys in other fields, little such knowledge is evident in the field of transport surveys. The standardisation of elements of travel surveys with regard to documentation and archiving would enable utilisation of all the benefits of the web-based technology of metadata and data archives on the market. However, until that milestone is achieved, a great deal of internationally coordinated work and effort has to be undertaken, requiring a range of institutional, organisational, and funding considerations to initiate successful development. If such quality standards were to become established in all invitations to tender for travel surveys, it would effect a great leap in quality and accessibility of meaningful data for the transport community as a whole.
