The International Transport Forum at the OECD is an intergovernmental organisation with 52 member countries. It acts as a strategic think tank for transport policy and organizes an annual summit of ministers. Our work is underpinned by economic research, statistics collection and policy analysis, often undertaken in collaboration with many of the world's leading research figures in academia, business and government. This series of Discussion Papers is intended to disseminate the International Transport Forum’s research findings rapidly among specialists in the field concerned.

The concept of the general purpose (GP) lane has dominated modern highway thinking and practice in OECD countries, especially for limited-access highways such as inter-city motorways and urban expressways, whether tolled or non-tolled. This paper raises the question of whether, in some circumstances, specialized lanes for light vehicles (cars, vans and pickup trucks) and heavy vehicles (generally more than two axles) might be cost-effective.
