摘要：Annual Average Daily Traffic (AADT) maps show, in a comprehensive way for expert as well as non-experts, the evolution of the relatively recent past (1965) until the most current image (2005). They help to analyse Barcelona’s city street network and retrace traffic congestion. The changes in the traffic patterns are due to random actions, resulting from individual liberties and voluntary planning, serving the general interest.
