The end of divisions in Europe had an outburst as a direct result of sudden passengers and trade flows along the roads and railway East-West axis. This has led to a significant burden on the existing transport infrastructures, particularly in the South-Eastern Europe, whose network was less developed. With the support of the European Union was launched a regional infrastructure development plan, based on National Master Plans, with intention to contribute at the same to time the "physical" integration into EU of these countries, until the planned policy accession in the incoming years.
The increasing flow of vehicles (passenger cars and commercial vehicles) on the main roads also imply the need to ensure higher levels of risk control and security, which otherwise are likely to weigh heavily on the social and economic development. This should happen within a transnational cooperation framework as a natural consequence of the integration process and of the increasing interdependence that points to the creation of a single space, eliminating the still strong tendencies towards fragmentation and individual approach to problems.
