SPACE - Speed Adaptation Control by Self-Explaining Roads - has published its first public deliverable, a state-of-the-art review entitled "Self-Explaining Roads Literature Review and Treatment Information". The literature review explores the evolution of the term ‘self-explaining roads’ and discusses various approaches to the concept. It further provides information about ‘self-explaining’ treatments that may have an impact on speed choice and would be appropriate for use on rural, single carriageway, higher volume roads. The review is available for download on the SPACE Public File Zone (.pdf).
