Organised by RoadPeace, the national charity for road traffic victims, speakers will represent most of the agencies dealing with road death and injury issues, from coroners and police officers to lawyers and journalists.
A welcome speech will be given by Mayor of London Ken Livingstone at the event, to be held on June 6 at Church House Conference Centre, Westminster, in London.
Keith Bradley, Home Office Minister for Victims, will provide a keynote speech at the event.
Brigitte Chaudry, founder and national secretary of RoadPeace, said: 'Road death and injury represents a major public health problem.
'It is the leading cause of death and acquired disability of our children. A third of all pedestrian casualties involve elderly people.
'The suffering of road traffic victims and the cost to families and society is enormous. Most of those deaths and injuries should be prevented.'
