Traffic Model in Urban Roads Planning from Surveys and Counts. Application to the City of Badajoz (Spain)

摘要

This paper describes the methodology used for the construction of a traffic model in Badajoz (Spain) starting with the allocation of the origin-destination travel matrix derived from surveys and traffic counts conducted in the southern and eastern accesses of Badajoz. The traffic model describes the mobility in potentially-captable future southern traffic relationships and allows the calculation of savings in travelled distance and travel times on the current situation. The traffic model allows to know different behaviours of the possible alternatives in the construction of a new high-capacity road. The model is able to select the one which captures more traffic and produces a bigger saving in travel time, meaning, the one which produces a better socioeconomic improvement. The research concludes in favour of the nearest corridor to the city centre, being this one the more crowded and the one that produces greater time savings. It is also the corridor that allows giving the Southern Bypass a dual purpose of collecting-distributing in the city of Badajoz.
