Abstract The widespread use of the Internet in recent years has allowed for a new way of conducting surveys. A survey located in a web page can be a very cost-effective tool for studies in marketing research, environmental economics and transport demand analysis. This type of surveys are inexpensive as respondents are contacted by e-mail and are invited to answer a questionnaire which is reached by means of a hyperlink. Once the survey is answered, responses are automatically saved in a data-base file from where information is available for processing and/or to be used for modelling purposes. We have recently conducted two internet surveys to elicit people’s preferences for improved road safety with encouraging results; the actual surveys can be obse rved at the sites www.ing.puc.cl/~piraguen and www.ing.puc.cl/~phojman. Their central part is a stated choice game in which respondents have to choose among two different routes with different levels of travel time, toll and accident risk. This paper describes how the two web pages were designed with respect to general lay-out, customisation of the stated choice game, respondents feedback and data-gathering. It also address the more delicate issue of the degree of randomness that can be attained in a web-based survey in the context of a developing country. All these issues are analysed in relation to ESOMAR guidelines (http://www.esomar.org/index.php). We finally present some comparative modelling results that serve to assess the quality of the data obtained. Although our results can not be extended to the whole Chilean population, due to the inherent non-random nature of the surveys, they are very illustrative of the fact that people do value safer roads and support the notion that safety should be included in a cost-benefit analysis of road investments. Our results have spawned an incipient debate in the country as to how safety should be considered within a general road infrastructure appraisal framework.
