This report presents an analysis of personal injury accident rates for roads in selected urban areas in developing countries. It shows, for a number of cities, the distribution of accidents by type of road, class of road-user and vehicle involved. It was found that in the cities studied, the accident and casualty rates (per licensed vehicle) were about 60 per cent greater than in urban areas in Great Britain. The fatality rates were found to be at least eight times greater than in Great Britain and up to thirty times grater than in the US. Relationships between accident rates and vehicle and pedestrian flows were derived and compared with similar relationships derived in Great Britain.
