The primary objective of Session V of the Symposium on Methods for determining geometric road design standards, Helsingor, Denmark, 10-12 May 1976, was to interrelate and improve road design elements as related to classes of roads. Most papers concentrated on new principles, new philosophies, and new methods. The papers focused in particular on what is behind the standards or what should be behind them. When making road design standards, or considering a road categorisation or classification scheme, it should be realized that this is done for the benefit of the road user. The road user can be considered on the one hand as the actual user of the road system, and on the other hand (on the operational level), as the most important element of the road-vehicle-man system. In this role he has to perform his manoeuvring tasks, which mans that he has to follow the course of the road and he has to avoid crashes with obstacles on the roadside. However, his possibilities to make the right decision e.g. in terms of the speed he chooses, are limited.
