About The World Road Association (PIARC)

The World Road Association (PIARC) brings together international experts to study current issues in road transport. The core members are from road agencies representing over 120 countries who participate in 18 Technical Committees (TCs).

Technical Committee members meet to share information and develop guidance for the benefit of the global transport community. Each TC is involved in developing reports and recommendations on good practice – in this case in the form of a knowledge-based website. Knowledge sharing is at the core of the World Road Association’s mission.

The Technical Committee on Road Network Operations and Intelligent Transportation Systems (B.1) is concerned with how to obtain maximum benefit from the existing road network infrastructure, which is a top priority for many countries. Improvements to capacity, reliability, safety, energy saving and the use of new traffic technologies and cost-effective applications are particularly important. Benefits can be gained by interfacing with other transport modes and the use of Intelligent Transport Systems.

In creating this website the objective has been to create an authoritative source of information about Road Network Operations (RNO) and Intelligent Transport Systems (ITS) based on practical experience. It is written for practitioners in need of technical advice on ITS for roads and intermodal operations, with a special emphasis on countries with economies in transition.

The audience for this website will be a mix of policy-makers, transportation practitioners, professionals, educationalists and students who work in transport planning, logistics, security and operations, transportation infrastructure, highways and traffic engineering, and vehicle engineering.

The Association invites young professionals who will constitute tomorrow’s global road specialist community to participate in its activities.

Christopher AllAn

Chris Allan has studied freight movements for many years. His PhD thesis focused on the movement of freight in the Victorian period, in particular global distribution patterns of coal and their impact on the shape of the world economy. It also analysed coal’s distribution within the urbanised environment of Victorian London in the period pre-dating motorisation, which has offered an unparalleled knowledge of traditional non-motorised freight transport approaches.

Chris has been utilising this knowledge to help create sustainable solutions to continued urban growth and resultant freight movements and distribution challenges.This has continued to develop his interests on the impact of freight on communities, and the integration of distribution into the urban fabric whilst maintaining and enhancing liveability and reducing accidents, congestion, environmental and noise pollution.
