In addition, it becomes an opportunity to set up a joint definition of the challenges of the future. Roads are, in essence, the infrastructure that allows the highest flow of both passengers and goods, while plays a main role to society as for its contribution to economic growth and social cohesion. Furthermore, roads are transport infrastructures that have historically experienced a significant development in several countries, becoming a key factor in their progress. However, we must continue putting our efforts into them, in order to continuously improve their performance, providing a better level of service for final users, a safer road network and the achievement of higher standards of connectivity with the rest of the transportation modes. Spain is a country with a vast experience in the construction and maintenance of infrastructures; it is recognized as a leader in technology, quality, efficiency and management of roads. Over the last 30 years, the development of one of the most extensive highway network in Europe is a proof of its capacity. It counts on more than 14,700 km long overcoming a challenging orography and showing an absolute respect for the environment. The 17th IRF World Meeting provides Spain with an incomparable opportunity to show our technical capacities and success stories to the international stakeholders. In addition, it is an excellent opportunity to foster the cooperation and networking of both Spanish companies and experienced professionals, to whom we owe the high-end quality of our infrastructures. The long-term goal is that they keep contributing to the development and improvement of road infrastructures all over the world. Jorge Fernández Díaz Minister of Home Affairs Firstly I would like to thank the Spanish Road Association for their kind invitation to participate in the special edition of its Carreteras magazine dedicated to the 17th International Road Federation World Congress, that takes place in Riyadh, Saudi Arabia. During this event, the Spanish industry will display the high scientific and technological level reached to the international road community. It is mandatory reminding the importance and priority of this area for the national economy, having achieved notable successes over the last few years. At the same time, the Spanish Government has worked along this policy. The Ministry of Home Affairs, concerned about accidents and understanding every single death as a tragedy, has also made a great progress in order to ensure the safety of road users. Figures, occasionally more eloquent than words, indicate that we are on the right track. The lowering of the number of deaths in road accidents in the recent years has been of high significance. The total road fatalities in 2012 (1,304) , is roughly the same figure registered in 1960, when 1,300 people died on our roads. This number is even more significant if we consider that 52 years ago there were only one million vehicles in the Spanish roads, while today the figures sum up to 32 million. Furthermore, death toll has been continuously dwindling during the last nine years. During 2012, there were 2,937 fewer fatalities than in 2000, when there were 4,241 fatalities. Consequently, the average daily number of killed has improved from 11,6 per day (in 2000) to 3.6 in 2012. Summarizing, 8 fewer deaths every day. Although these data clearly mark a positive trend, they are not a reason for complacency. On the contrary, they are an incentive to keep on working hard to find new ways of enhancing the safety of all road users. With this objective in mind, last July I promoted the reform of the Traffic and Road Safety Act in the Council of Ministers, which was approved. Changes are relevant, as they will allow the adaptation of the law to drivers’ needs, but also to the changes of vehicles and roads, determining key factors of accidents. There are several sectors and stakeholders highly responsible for road safety; together, we must ensure that roads are not identified with accidents anymore. Roads are ways for communication, infrastructures that create wealth, progress and welfare for citizens, not places where people can lose their lives. For all the above reasons, the Ministry of Home Affairs will continue working with tenacity and perseverance to ensure that the current descent in the death toll is maintained in the long-term.
