SPEED LIMITS, SAFETY AND STREET CAPACITY

GESCHWINDIGKEITSBEGRENZUNG, SICHERHEIT UND STRASSENKAPAZITAET

The article aims at providing an objective assessment of the possibility of increasing motor safety by means of speed limits from the point of view of a brakes expert. Theoretical bases for the spacing of vehicles driving in convoy are indicated and compared with previous studies of convoy behaviour. In addition, the study considers approach behaviour and street capacity or traffic flow, examines the relation between theory and actual driving behaviour and draws conclusions from both. It is shown by means of examples that speed limits do not represent an efficient means of reducing accidents. It is much more important to provide drivers with adequate instruction. In order to do this properly it is necessary to systematically assess the collective behaviour of drivers. The limits determine the collective behaviour of drivers. The limits set by HOEFS permit interesting speculations. They show that those methods for reducing the laws governing traffic behaviour previously used and based on the "consideration" principle have no real purpose. The calculated behaviour of drivers which is obviously based on statistical laws must be included in the calculations. /TRRL/
