In 2004, the Scottish Executive and Scottish Road Safety Campaign (SRSC) commissioned ODS to 'investigate the travel patterns and road safety education requirements of children with Additional Support Needs, and put forward recommendations on how their needs may be more effectively met'. The study was to focus particularly on the needs of children with mild to moderate learning difficulties, including autistic spectrum disorders and Attention Deficit Hyperactivity Disorder. The study involved a postal survey of 300 nursery, primary and secondary schools in Scotland; discussion with children with Additional Support Needs and their parents; and consultation with a range of local and national representatives and support organisations for those with Additional Support Needs.
