Example Embodiment

[0043] Example

[0044] see figure 1 , 2 , 3, 4. Set up reversible short lanes. exist figure 1 In the intersection shown, one is set in each direction of S and N l i = 50m long reversible short lanes, one in each direction of E and W l i = 40m long reversible short driveway.

[0045] Set reversible short lane indicator lights and left-turn motor vehicle pre-signal lights. exist figure 1 In the shown intersection, the left-turn pre-signal light 8 is set on the right side of the stop line in the S direction, the left-turn pre-signal light 5 is set on the right side of the stop line in the E direction, the left-turn pre-signal light 2 is set on the right side of the stop line in the N direction, and the left-turn pre-signal light 2 is set on the right side of the stop line in the W direction. Left-turn pre-signal light 11 is set on the right side of the stop line.

[0046] Set the reversible short lane indicator 9 at the exit in the S direction, set the reversible shor...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of urban road traffic control, and relates to a signal control method for a left-turn motor vehicle passing through a reverse lane at a level intersection entrance. Background technique [0002] With the rapid development of the urban economy, the limited urban road land can no longer meet the increasing car ownership, and the intersection congestion is becoming more and more frequent, resulting in multiple parking at the intersection, reduced traffic quality at the intersection, noise pollution, and vehicle exhaust emissions. Various traffic problems such as traffic increase. There are often fewer vehicles on the exit road at the intersection, and the queue of vehicles on the entrance road is too long, resulting in multiple parking situations. How to design an intersection that can not only preserve the existing buildings without a large number of demolition and reconstruction projects but also meet the increasing t...
