This paper outlines the approach of the British Road Federation (BRF) to speed limits for modern roads in the wider context of road transport, environment protection, and sustainable development. Greater emphasis on public transport, cycling, walking, and land use planning must be complemented by goods roads. Accident statistics show that there are still far too many accidents and casualties in the UK, despite dramatic improvements in recent years. Inappropriate speed contributes to many road accidents, but mainly on roads with limits of 30mph, 40mph, or 50mph. Priorities for action here are: (1) improved and stricter enforcement; (2) speed limit reviews at accident black spots; (3) more effort to place the right traffic on the right roads; (4) improved service on strategic highways; and (5) wider use of dynamic control for peak period flow control. There is no need to change limits on high standard roads in general, but 20mph zones in residential and shopping areas need to be upgraded. Road capacity in congested conditions needs to be maximised at a steady speed with good lane discipline. Fuel effiiency is maximised at speeds of 60-90kph. Speed limit policies should be part of a package which improves quality of service, especially journey time reliability. For the covering abstract see IRRD E100685.
