ABSTRACT
Surveys which require the active involvement of those being surveyed in some form of interview, questionnaire or discussion may be termed 'participatory surveys'. These surveys can supplement observational surveys by providing much more detail on individual travel patterns and by providing information on the characteristics of the travellers, their attitudes towards travel and their reasons for making one kind of trip rather than another. A major transportation study may require information on all these aspects and may use a combination of discussion groups, interviews and questionnaires to obtain it. This chapter covers only the principal issues involved in organising such surveys and the reader is advised to consult more specialist sources for further details (see for example references 1 and 2).
