Surface Transport Networks: Improving Reliability and Levels of Service
The Joint Transport Research Centre of the OECD and the International Transport Forum conducted a study on surface transport networks: improving reliability and levels of service. The study investigated the performance of transport networks in the major OECD/ITF regions. It focused on the reliability and levels of service of these networks for the international movement of passengers and goods and make assessments of performance and drew comparisons across regions. It explored the effectiveness of current operational arrangements and performance measures, identified possible improvements (including in service reliability) and - in the context of expected future increases in demand - drew conclusions on the priorities for regional/international transport policy and the nature of improvements needed for surface transport network operations.
This study examined how governments can improve reliability and levels of service for the movement of passengers and goods in surface transport networks. The primary focus was on interurban movement of passengers and goods on roads, rail and, to a some extent, at ports with their hinterland connections.

This study defined reliability from the perspective of different users. It considered how reliability may be understood by users and managers of transport networks. It also reviewed the current and projected impediments to acceptable reliability in different countries and regions. The study then reviewed issues on measuring reliability in the transport system. The study presented an overview of different ways of how reliability can be measured and monitored and what kind of indicators are to be used for this purpose. To provide insight into the value of reliability for society, the relative importance of changes in reliability were compared to other system attributes. The study examined possibilities for evaluating the value of reliability (on top of the value of time) for cost-benefit analysis. The study also considered the role of pricing in improving the level of transport reliability, with the longer-term aim of ensuring efficient levels of reliability across the transport sector.
