Abstract: Embodiments of the present disclosure can provide a road traffic analysis method and an apparatus. The method can comprise obtaining a traffic parameter of a road intersection by analyzing road traffic information of the road intersection, determining a reference adjustment length for each phase of a traffic signal cycle corresponding to each lane of the road intersection based on the road traffic information and the traffic parameter. The traffic signal cycle has one or more phases. The method can also comprise determining a first adjustment length when a difference between the reference adjustment length and the first adjustment length satisfies a condition associated with the lanes of the road intersection and the corresponding traffic parameter, and adjusting the phases of the traffic light cycle at the road intersection based on the first adjustment length for each phase.

Abstract: Rotatable valve assembly includes a mounting mechanism for rotatably mounting a valve in a housing. The mounting mechanism includes a shaft having an outside end extending through the housing. A conversion mechanism converts fluid pressure in the housing into torque exerted on the shaft. A release mechanism is located outside the housing for preventing rotation of the shaft and valve when the torque exerted on the shaft is below a selected magnitude. A linearizing mechanism converts the forces exerted on the release mechanism by the shaft into a linear force. The release mechanism allows the shaft to rotate when the torque exerted on the shaft and the linear force exerted on the release mechanism exceeds a selected magnitude. A seal is provided for sealing the gap between the valve and the housing in the closed position of the valve.

Abstract: The present invention provides a pressure surge resistant rupture disk assembly adapted to be sealingly clamped across a pressurized fluid containing passageway. The assembly basically comprises first and second rupture members having predetermined rupture pressures, the second rupture member facing the pressurized fluid and having a predetermined rupture pressure equal to or lower than the rupture pressure of the first rupture member. At least one opening is provided in the second rupture member for allowing a restricted pressurized fluid flow therethrough.
