METHOD FOR SIGNALLING COVERAGE OF ROAD INTERSECTION AND BYPASS PATHS THEREOF Russian patent published in 2015 - IPC G08B25/00 G08B13/00 

FIELD: physics.

SUBSTANCE: invention can be used when employing detection means with an extended flexible linear part in the form of a flexible cable, which are based on a wave-conduction or vibration detection principle, for signalling coverage of a four-way road intersection and bypass paths thereof. The method includes deploying, at a four-way road intersection and the adjacent area, two detection means with an extended flexible linear part such that they each cross three roads on a semicircle without crossing each other, extensions of said extended flexible linear parts lie along two roads through which the most likely directions of bypassing the intersection by an offender pass, and using an output algorithm which determines the direction of movement of the offender based on the order of arrival of one to four alarm signals over established time intervals for accumulation thereof.

EFFECT: high probability of detection, specifically detecting an offender when the offender moves in all directions, and accuracy of indicating the direction of movement of the offender, specifically from twelve directions of movement on an intersection - four are determined in pairs and eight uniquely, the directions of bypass are also determined in pairs when signalling coverage of a road intersection and bypass paths thereof using only two detection means.
