Abstract
Society today presents a demand for greater interchange on all levels. To satisfy this demand we need more and better transport infrastructures. As this requires a high degree of investment, not all proposals can be carried out. Plans proven to be necesary and even urgent for same people have therefore to be postponed or rejected in the face of budgetary limitations. This problem is solved by a decision-making process. This study proposes a accessibility indicator which allows us to quantify the degree of improvement benefitting the user when a new highway is built. The formula is applied to three transport plans which have been put forward as solutions to the difficult traffic conditions in the metropolitan area of Madrid. This enables us to establish a method for maximizing use of the available budget and at the same time to evaluate the user's benefit. The results confirm the validity of the method. It's calculated the degree of general accessibility (for all motives for travelling) and the degree of accessibility for journeys to work. The results permit an analysis both of overall improvement in the whole province and in each municipality thereof. In this way we can determine regional benefits of each project.

Summary
Society today presents a demand for greater interchange on alI levéis. To satisfy this demand we need more and better transport infrastructures. Todo indicador de accesibilidad ha de contar, para ser completo, con variables que representan los tres componentes del viaje. Los indicadores empleados corresponden, en general, a los de tipo Topologico, que consideran exclusivamente las distancias entre los nodos del grafo de la red. Queremos proponer ahora un tipo de indicador, basado en los modelos de gravedad, pero que mida las posibilidades que proporciona al usuario individual una determinada infraestructura de transporte, para satisfacer su demanda de bienes y servicios. Donde Dij es la DISTANCIA OPERACIÓN AL (8), que se basa en la medida de la distancia mínima entre el origen y el destino y en la consideración de las condiciones estructurales y de circulación bajo un Coeficiente de Impedancia para cada tramo. Sobre este grafo se ha realizado el cálculo de la ACCESIBILIDAD INDIVIDUAL en los dos casos definidos en el apartado anterior: viajes por todos los motivos (General) y viajes al trabajo (Empleo)
