Abstract
The trends of Road Traffic Accidents (RTA) in PNG illustrate a rapidly growing problem for developing countries. In this paper data of a time series for twenty years are analyzed to ascertain the trends in main indicators and injury rates. The relationship of injuries to road users and type of vehicle highlights the problems of passengers of utility vehicles and buses. An emerging problem of RTA due to use of light coaches for passenger transport is highlighted. The need for behavioral interventions and tighter regulations is argued.
