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.

Infrastructure Supply – Provision as a Policy Tool

International Transport Forum

This section reviews the principles of infrastructure provision to influence the level of network reliability. Options reviewed for improving reliability include supplementing capacity when reliability is undermined by heavy demand and setting cost-effective infrastructure standards. The capacity options include building new rail lines and adding an additional highway; examples of cost-effective capacity include technical standards for the materials to be used and hence affecting maintenance levels, renewal rates or robustness to natural disasters. The section then discusses the practicality of infrastructure provision as a policy tool to improve reliability.
