This study is to investigate further how best to manage speed on the rural, non-motorway road network and to build on outputs from current and recent trials of rural safety measures and other research on speed and the application of speed-accident results. This will bring together existing knowledge, report and make recommendations about speed accident relationships on rural single carriageway roads, and carry out an appraisal and development of the 'self-explaining' roads concept. It will also develop further the hypotheses and findings of the EU MASTER project applicable to rural road speed management.
