Developing countries are nowadays considering exclusive or semi-exclusive transit system implementation. Such systems need to be planned well; attractive to car-owners and affordable to the transit captive users. Therefore, survey becomes essential to grasp preference from all segments of potential users. However, in developing countries, their response for questionnaire survey using hypothetical questions is less reliable because of users’ lack of knowledge about such transit systems and trading-off in hypothetical questions. This study aims to propose a systematic approach for questionnaire design in the contest of developing countries. Two different surveys with hypothesis system (BRT for Sri Lanka) were conducted: (1) System explanation ways of with and without pictures in questionnaire; and, (2) Level of complexity of the hypothetical questions. This study concludes that, in developing countries, questionnaires need to be attentive in questionnaires design. Even if questionnaires are conceptually same, few structural changes affect users’ response considerably.
