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.

Pricing Networks to Optimise Reliability

International Transport Forum

This section reviews the principles of pricing for network use to influence the level of network reliability through demand management; and to supply differential levels of reliability reflecting granularity in user values of reliability. It has been noted, earlier, that reliability is often bundled with other attributes such as speed, convenience and cost, from which it can be very difficult to differentiate a separate market for reliability. Following on from this issue, this section considers how practical it is for pricing to deliver the levels of reliability consistent with diverse values placed on reliability.
