Abstract: The present invention discloses sections of highway traffic infrastructures, including multipurpose structures, for best combining renewable energy and traffic assistance systems along the highway. According to a first innovative aspect, the distribution of structures accounts for aspects such as driving comfort, (urban) landscape integration and adjustment to energy demand and traffic circulation conditions. According to a complimentary innovative aspect, ample elevated constructions, as required by solar and wind energy systems, combine with certain dimensional dispositions, as required by different traffic assistance means, in view of enhanced energy distribution and traffic safety.
