Reversible short lane signal control method based on intersection vehicle in-turn release
The invention discloses a reversible short lane signal control method based on intersection vehicle in-turn release. According to the method, four inlets in the east, south, west and north at an intersection are respectively provided with one segment of reversible short lane by utilizing opposite lanes, four outlet lanes are respectively provided one set of reversible short lane indicating lamps, right sides of stop lines of the four inlets are respectively provided with one set of left turning pre-signal lamps, main signal lamps at the intersection employ a clockwise or anticlockwise in-turn release four-phase mode for all vehicles at each inlet lane, phase difference between the main signal lamps and the left turning pre-signal lamps is set, and the reversible short lane indicating lamps and the left turning pre-signal lamps realize simultaneous conversion; phase difference between main signals and left turning pre-signals is coordinated, public period duration and green light distribution time are calculated, conflicts between a left turning traffic flow and an outlet lane traffic flow are controlled in the time aspect, left turning traffic flow jam caused by improper time distribution is avoided, inlet and outlet land resources are fully utilized, the lane number of inlet lanes is enhanced, and passing capability of the intersection is improved.
