In Europe, governments invest EUR 100 billion in transport each year to provide people and firms with better access. Accessibility indicators can be used to capture the benefits of these investments, for example by measuring how many destinations can be reached. In that sense, they are a significant improvement over indicators such as speed, capacity or congestion. However, they are seldom used in decision-making. Furthermore, accessibility indicators often primarily reflect the spatial distribution of destinations rather than the performance of transport networks.
