Improving flow and safety upon roads by unorthodox layout.
When roads have at least two lanes, overtaking has to take place exclusively within these two lanes, and intruding into the opposite stream when overtaking is strictly forbidden. As a result, a completely new situation emerges - the situation of two neighbouring one-way roads. Examples are given on how to treat them separately for improving flow and safety in carefully selected situations.
