Optimization of Local Road Network Quality

Abstract

Optimal management of a road transport network is requested to ensure adequate safety and comfort standards to users, while containing the generalized transport cost. It is necessary that the administrations which manage roads adopt an adequate tool to monitor the network supply (DSS), giving an efficient technical support for decisions at different levels of competence. This assumes relevance for the choice of maintenance intervention alternatives especially in areas of environmental complexity. In the present study a methodology of analysis is presented, relating the construction of an information set to the definition of a matrix R = rij, (i = 1.n; j = 1.m), being n the number of links of the network and m the indicators used (performance, econometric, accidents, environmental, etc.). Finally, using a specific statistic method, we arrive to an assessment of the relative significance of each of the m vectors (of dimension n) representative of the synthesis.
