FIELD: transport.SUBSTANCE: method includes synchronisation of reference transmitters clocks, measuring time of radio signal run from antennas of three and more reference transmitters located at distance from transport facilities (TF) and pedestrian to antenna of radio navigation device located on TF or pedestrian, calculation of TF and pedestrian coordinates using computing device, transmission of TF and pedestrian coordinates data and their identification numbers to information computer centre via radio channel, and transmission of alert signals to road users. Radio masts with reference transmitters are installed along roadway in fixed points with known three-dimensional coordinates of antennas. Reference transmitters clock synchronisation with the clock of information computer centre is performed via existing between them optical carrier. Digital road map is created by means of splitting roadway into pixels with known three-dimensional coordinates, with indication of coordinates and meanings of road signs and traffic lights. On TF, two radio navigation devices mutually spaced along TF longitudinal axis are installed, and from their continuously measured three-dimensional coordinates and digital road map the TF position relative to axial line of roadway is determined at any moment.EFFECT: invention provides higher traffic safety.8 cl, 2 dwg |
