Abstract

This paper analyses the economic lifetime of roads in Sweden using a data over kilometres of new roads together with road network data and a centrality index constructed from population statistics. The relation between economic lifetime and centrality is performed by poisson regression. It is shown that roads in more central parts of the country and in parts more affected by population changes (increase) generally have shorter economic lifetimes. The analysis shows economic lifetimes of Swedish roads to be between 25 and 111 years, with the majority of the economic lifetimes in the upper part of this range (above 70 years).
