METHOD OF CONTROLLING ROAD TRAFFIC AT INTERSECTION
FIELD: physics; signaling. SUBSTANCE: invention relates to controlling road traffic and specifically to controlling road traffic at an intersection. The method involves setting the time for switching the traffic light signal on the given direction of motion proportional to the length ? of the road section, occupied by vehicles from the boundary line of the intersection to the final boundary of the road section, occupied by the vehicle on that road section, and the number n of vehicles on the given road section taking into account speed of vehicles before the intersection and the time lag before the next vehicle starts moving after the previous vehicle. The time for switching traffic light signals is determined using the expression where tsw is time for switching traffic light signals; W is average speed of vehicles before the intersection; ?pr is average lag time before the next vehicle starts moving after the previous. The greatest value ?cr for opposite directions of motion on the intersection is selected, and values ?cr, W and ?pr are corrected depending on traffic flow conditions and state of the road. EFFECT: prevention of asymmetrical accumulation of vehicles before a traffic light on an intersection, avoiding unjustified delays and traffic jams at intersections, which reduces stoppages of vehicles and combustible and harmful emissions into the atmosphere. 2 cl, 2 dwg.ΠΠ·ΠΎΠ±ΡΠ΅ΡΠ΅Π½ΠΈΠ΅ ΠΎΡΠ½ΠΎΡΠΈΡΡΡ ΠΊ ΠΎΠ±Π»Π°ΡΡΠΈ ΡΠΏΡΠ°Π²Π»Π΅Π½ΠΈΡ Π΄Π²ΠΈΠΆΠ΅Π½ΠΈΠ΅ΠΌ Π°Π²ΡΠΎΡΡΠ°Π½ΡΠΏΠΎΡΡΠ° ΠΈ, Π² ΡΠ°ΡΡΠ½ΠΎΡΡΠΈ, ΠΊ ΡΠ΅Π³ΡΠ»ΠΈΡΠΎΠ²Π°Π½ΠΈΡ Π΄Π²ΠΈΠΆΠ΅Π½ΠΈΡ Π°Π²ΡΠΎΡΡΠ°Π½ΡΠΏΠΎΡΡΠ° Π½Π° ΠΏΠ΅ΡΠ΅ΠΊΡΠ΅ΡΡΠΊΠ΅.

TUYERE FOR SUPPLY OF ACOUSTICALLY EXCITED GAS JETS TO WORKING SPACE OF POWER TECHNOLOGICAL UNITS
FIELD: power industry. SUBSTANCE: tuyere includes housing with water cooling and outlet nozzle of tuyere for acoustically excited gas. Inside the tuyere on one axis with it there located is gas jet acoustic radiator consisting of nozzle, resonator and reflector. Distance from the end of resonator to nozzle exit section of tuyere is 4-5 diameters of resonator. Nozzle exit section of tuyere has different orientation relative to its longitudinal axis within the angle range of 0-45Β° between axis of tuyere and axis of its nozzle. EFFECT: decreasing overall dimensions and cost of tuyere, and reducing the required gas medium flow rates for creation of sound oscillations. 2 dwg.ΠΠ·ΠΎΠ±ΡΠ΅ΡΠ΅Π½ΠΈΠ΅ ΠΎΡΠ½ΠΎΡΠΈΡΡΡ ΠΊ ΠΎΠ±Π»Π°ΡΡΠΈ ΡΠ½Π΅ΡΠ³ΠΎΡΠ΅Ρ
