Various traffic measures are being introduced today but often they are done largely without any rationale as to what it is that it is hoped to achieve. The first part of the paper argues the case that it is not the safety of navigation alone which should be considered but the safety of cargo as well, for the risk to society derives from the nature of the cargo. Experience in many ports and waterways highlights the fact that despite the existing and increasingly rigorous safety measures relating to the carriage of hazardous cargo, which normally relate only to what happens on board the ship or at berth, it is entirely possible for localized encounters of risk cargoes to occur in limited sectors at one time. The second part of the paper considers one form of traffic regulations that could be implemented, with the main objective of limiting the amount of dangerous cargo passing through a given area. The scheme is termed the "safety-factor index" or "sector population concept", and has three main features. Each ship has a safety-factor number allotted to her, a low number denoting relatively minor environmental consequences for any casualty involving the ship and a high number denoting disastrous consequences. The total sum of the safety-factor numbers for all ships within a controlled area at any point of time should not exceed a predetermined level known as the "safety factor index".
