The invention relates to an optimization method for a combined phase position of a needed lane. According to the saturation of an intersection, a phase position optimization method under proper lane control is adopted. If the saturation is larger than one, a phase position optimization method under super-saturation lane control is adopted, and otherwise, a phase position optimization method under under-saturation lane control is adopted; the flow balance degree of a lane permitting vehicles to pass through in the phase position is calculated in real time, on the premise that the condition is met, a capacity increasing lane is inserted, the capacity increasing lane and a key lane form a small phase position under the phase position, and therefore vehicle flow can be balanced, and finite space and time resources can be fully utilized; when the phase position is optimized, the period of the intersection is adjusted in real time and optimized, it is guaranteed that lanes in high transportation demand take priority to permit vehicles to pass through particularly in an environment where the vehicle flow of the lane is large, and coordination control of vehicle flow between the key lane and a downstream intersection is adjusted in real time. According to the method, not only are the time and space resources fully utilized, but also the traffic jam problem under large flow is relieved to a certain extent.

A folding chair with arms includes two back-rest tubes, two seating frame tubes, a pair of front crossed tubes, a pair of rear crossed tubes, a chair fabric, and a pair of soft or rigid arms. Each of the back-rest tubes is connected cross-wise to one of the seating frame tubes. The upper portion of each of the rear crossed tubes is connected to one of the back-rest tubes via a U-shaped hinging element. The front crossed tubes are cross-wise connected, and at the crossed connection point is provided a support reinforced block. The upper portion of each of the front crossed tubes is connected to one of the seating frame tubes via an eccentric U-shaped hinging element and a fixing element. The lower portion of each of the front crossed tubes is connected to the lower portion of one of the back-rest tubes via an eccentric U-shaped hinging element.

An air freshener of the invention includes a rotating box, a fixed base disposed on the rotating box, the rotating box rotating with respect to the fixed base, and a perfume box filled with a perfume, which can rotate with the rotating box. The rotating box has an annular shape in cross section and has an internal space for receiving and embedding the perfume box therein. Air holes are formed in the fixed base for exposing a portion of the perfume box when the rotating box is rotated with respect to the fixed base. The air freshener of the invention is applicable to be used inside a car or a room, and is capable of both refreshing the air and adjusting the release amount of the diffused perfume vapor.
