APPROACH TIME EQUALISER FOR FLASHING LIGHT INSTALLATIONS FOR LEVEL CROSSINGS. BASIC THEORETICAL STUDIES
This report deals with the theoretical possibilities for the use of time-equalisers. It presents analytical and graphical methods permitting, under various pre-determined circumstances, the operating conditions for these installations to be determined. The conclusions, particularly those which concern the saving in distance, are shown on speed-distance diagrams (see figure 16, Sg, tg). When reading these diagrams it is possible to decide at what point the train, which is approaching the level crossing at the speed which it is desired to study, begins the warning period. The report therefore allows judgment to be passed on the principles of operation which hold for a chosen rate of acceleration. Various other numerical studies show, for example, the effect of various rates of acceleration and will form the basis of the next report. The present report shows, in addition, the findings of the enquiry carried out by the Committee with the object of fixing the constants which will subsequently be used.
