IMPACT ANALYSIS OF ROAD KEEPING: CASE STUDY OF LAPLAND DISTRICT IN FINLAND

The northernmost highway district of Lapland, Finland, differs considerably from other regions in Finland. Its road network is very long, about 9000 km, whereas traffic volumes are low because of an extremely low population density. The arctic climate puts severe restrictions on the technology used, the amount and quality of winter maintenance, and road standards. To fully comprehend the implications of proposed budget cuts, the district initiated an analysis on the impacts of alternative strategies. A network-level pavement management system was used to allocate and optimize funds for rehabilitation and to analyze the development of the condition of the network with nonoptimal funds. Summer and winter maintenance were analyzed by an analytical hierarchical process. As to investments, in addition to a traditional cost-benefit analysis, indirect economic effects were studied with a regionalized input-output model. According to the results the pavement condition targets cannot be achieved with the current budget level, maintenance moneys can be decreased somewhat, and cuts in investment funds have very harmful effects on the local companies and employment. The preliminary results suggest that rehabilitation, summer and winter maintenance, and highway investments are not, mathematically speaking, separable and thus cannot be viewed independently of each other. This being the case, road keeping must be seen as a whole and the optimization of the funds allocated to its subcomponents must be done simultaneously with a global and comprehensive optimization function.
