METHOD FOR SIGNALLING COVERAGE OF ROAD INTERSECTION AND DETOURS 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 linear part, which are based on a wave-conduction or vibration detection principle, for signalling coverage of a four-way road intersection and detours thereof. The method includes deploying, at a four-way road intersection and the adjacent area, two detection means with an extended linear part such that the extended linear part of each means overlaps two different roads, one twice and other once, with the ratio between the distances from the centre of the intersection to the intersection points of 1:2:1 and using an output algorithm which determines the direction of movement from a sequence of one to four alarm signals coming from the detection means over a set time for accumulation thereof, and the ratio between time intervals of delay between the arrival of signals. The method includes a preparatory step with deployment based on a developed scheme of the extended linear part of two detection means on an area and a main step which begins from the moment an offender enters the detection area of one of the detection means, during which the offender is detected, and the direction of movement of the offender is determined.

EFFECT: high probability of detection and accuracy of indicating the direction of an offender during signalling coverage of a road intersection and detours thereof using only two detection means.
