Abstract:This paper describes how in the past, road construction in Mexico was linked more to sociopolitical concerns than to technical or economic studies to justify their construction. Now, new approaches are considered for the planning, construction, maintenance and operation of the roads, taking into account traffic data gathered from technical studies to serve adequately transport demand and trying to achieve the lowest cost and the highest safety levels. After a description of the early efforts in the subject, this paper reviews the work done in the area of traffic data collection and use for the last thirty years at the Mexican Ministry of Transport (Secretaria de Comunicaciones y Transportes, SCT). The article describes the approaches taken in the nineteen fifties and sixties to measure vehicular flows on the roads. It also reviews later implemented approaches that established strategies to know other information such as traffic composition, point speeds and origin and destination of trips. Finally, the paper elaborates on a proposal for the future of traffic data collection in Mexico.
