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.

Influencing Supply – Management as a Policy Tool

International Transport Forum

This section reviews the principles of managing the network to influence the level of its reliability. Management options reviewed can be divided into two categories: pro-active and active. Pro-active management of infrastructure mainly includes identification of network vulnerability to recurrent and non-recurrent unreliability. Dynamic processes, in turn, focus on active management of network to intensify oversight of network use once a network incident arises; such management systems include traffic control, accident clearing teams and rerouting strategies. Further, this section also discusses delays faced in different types of interfaces, such as those between ports and hinterland connections, borders of organisational interfaces.
