By using telecommunications, Intelligent Transport Systems (ITS) improve traffic safety and efficiency, facilitating an integral transport of people and goods. Even with the benefits obtained through ITS nowadays, significant innovations will take place in the coming years such as the ubiquitous and integral use of computer vision, or the development and future implementation of Cooperative ITS systems that will allow direct communication between vehicles (V2V, Vehicle-to Vehicle) and with the roadside elements (V2I, Vehicle-to-Infrastructure) by means of mobile and wireless communication. In this context, comes the INTELVIA project, with the clear objective of developing ITS technologies to obtain the advantages of using information and communication technologies in the field of road transport and traffic management. This document presents the INTELVIA project, describing the main technological solutions provided for the design and development of an integral traffic management system and showing some tests which have already been done.
