This report describes research that examined the attitude and behaviour of drivers towards cycle users. A range of qualitative and quantitative research techniques was used, including the use of virtual reality equipment to simulate encounters between drivers and cyclists. Variations in driver attitude and behaviour based on a number of factors, including physical infrastructure and cyclists behaviour were examined. The research also examined the effectiveness of two different approaches to improving drivers' consideration of the needs of cyclists. The report makes recommendations to improve driver training, for the layout of roads and for future campaigns to raise awareness of cyclists among drivers.
