The environment protection management system (EPMS) is a system for measuring the various quantities of pollution produced by road traffic (emissions, noise, vibration), reducing them with various means such as traffic flow control, the provision of traffic information, and route guidance for individual vehicles, maintaining the health of roadside residents and pedestrians who are exposed to automobile exhaust emissions, and protecting the environment. Traffic pollution, having relatively little effect that would bring pronounced direct physical harm as corporate emission pollution does, has been overlooked because it was buried amid a vortex of corporate emission pollution. Today's economy is highly dependent on automobile traffic, making it difficult to greatly reduce overall traffic volume by such means as traffic regulations. Research is going on to reduce pollutants, noise, and vibration by the installation and improvement of desulfurization equipment, more-advanced engines, and newly constructed highways. The National Police Agency has developed an EPMS as one of the subsystems that make up universal traffic management systems (UTMS).
