Improving Reliability on Surface Transport Networks

image of Improving Reliability on Surface Transport Networks

Passengers and freight shippers alike want reliable transport services.  Surprisingly, little research has been undertaken in incorporating reliability into the assessment of transport projects despite the increasing importance of scheduling in economic activities.

This report provides policy makers with a framework to understand reliability issues, to incorporate reliability into project assessment and to design reliability management policies. It also explores a range of reliability performance measures. Case studies across OECD and ITF countries provide examples of several core policy tools that can be used to deliver more reliable networks in a cost-effective manner.

The report makes significant progress in identifying appropriate methodology for incorporating reliability into policy and project evaluation, as well as exploring the pitfalls that need to be avoided.

Executive Summary

International Transport Forum

Most of us face unreliable travel services in our daily lives, with unexpected delays leading us to miss a train or arrive late for school or work. Whether it be for social or business events or deliveries of goods, reliability is a key quality of movement. A review of policies in ITF/OECD countries shows, however, that few countries explicitly incorporate reliability into transport policy making. This report aims at providing policy makers with a framework for understanding reliability issues, for incorporating reliability into project assessment, and for designing reliability management policies.
