Stages of statistical strategy in Mobility Household Surveys. Challenges addressed

All research on the issue of public and urban transport requires the design of simulation models, based on knowledge of the situation and on the forecast of its evolution from considering different scenarios. For the development of transport models it is necessary to reach a broad knowledge of the supply and demand system. Demand models, require a particular instance of gathering information about a set of variables associated with travel and socioeconomic characteristics of the users of the system, for which purpose, it has to be done survey using different statistical techniques among which are: household surveys, censuses and surveys of travel origin and destination in points of interception and opinion surveys. Surveys Consist of field operatives supported by different sampling designs depending on the type of survey used. Like any sampling process, requires evaluation to exercise control over the errors or biases admitted at various stages of production of information. This work focuses its development on household surveys, seeking to provide a brief description of the difficulties encountered and the solutions adopted at the various stages during the performance of this type of surveys applied to the mobility issue, highlighting the involvement of statistics throughout the process. In this sense, th
