The number of victims of road traffic accidents in urban areas of Spain has, encouragingly, dropped in the period between 2000 and 2005, with the figure falling by around 3% each year. However, if the Spanish situation is taken within a European context and if a relative measurement such as the number of road traffic related fatalities per million inhabitants is considered, Spain still occupies the thirteenth place in the Europe of the 25 Member States. One must also take into account that 52% of accidents with victims currently take place on local roads. In this scenario, the improvement of urban road safety can only be tackled with the combined participation of the Public Administrations and the collaboration of all of the involved social and economic agencies. Each organization and sector must intervene from their particular territory, fulfilling the responsibilities that are assigned to them through actions of many diverse types -education, training, technology, regulations, road design, environment, town planning, etc.,- in order to find solutions to the complex question of road traffic accidents at a local level, since it is the local administration that plays a decisive role in reducing the number of accidents. The Urban Road Safety Master Plan (Plan Tipo de Seguridad Vial Urbana) presented in this document attempts to move forward using a two-pronged attack, in accordance with the objectives set down in the Strategic Road Safety Plan (Plan Estratégico de Seguridad Vial) 2005-2008. On the one hand, those people responsible for the municipal governance of mobility issues will be provided with the resources and instruments necessary for them to move forward in urban road safety planning. On the other hand, common objectives will be defined and procedures and methodologies which allow the problems of road safety affecting a particular municipality to be analysed will be established and agreed upon, comparing the situation of one area with that of others and deciding upon common and homogenous measures and courses of action. Therefore, this guide is an attempt to create a tool which facilitates the work of the politicians and municipal technicians responsible for road safety and sustainable mobility. Likewise, it aims to aid the implementation of new intervention strategies and action proposals whose application allows us to move forwards together towards the prime objective: reducing urban road traffic accidents and their consequences. Only with the commitment and the active participation of all of us will it be possible to make this wish a reality.
