Embodiment

[0041] Example: Combine below Figure 1 to Figure 3 This embodiment will be described in detail.

[0042] In the method of borrowing the opposite exit lane to eliminate the left-turn phase of an intersection as described in this embodiment, the intersection is an intersection area of ​​two roads, and the number of lanes of the road is greater than or equal to 4;

[0043] There are lane changing areas for left-turning vehicles on both road sections;

[0044] The method includes the following steps:

[0045] Vehicles waiting to turn left on roads in a prohibited state change lanes in the left-turning vehicle lane change area, enter the opposite exit lane in advance, and queue to wait for a left turn;

[0046] When the road is running in the straight phase, the vehicles waiting to turn left and the vehicles waiting to go straight pass in the following way:

[0047] Vehicles waiting to turn left turn left into the intersection of road exit and leave the intersection;

[0048] Wait for the st...

Abstract

The invention discloses a method for eliminating a left-turn phase of an intersection by borrowing an opposite exit lane, and belongs to the technical field of traffic engineering. The problem that anexisting plane intersection traffic organization and signal control cannot achieve intersection space-time resource sharing by left-turn vehicles and opposite going-straight vehicles is solved. The method comprises the following steps of setting a left-turn vehicle lane changing zone on two intersecting roads, in a straight line phase operation period in a road direction, enabling vehicles aboutto turning left in the other road direction to change lanes in the left-turn vehicle lane changing zone to enter into the opposite exit lane, when the other road is running in a straight line phase, vehicles about to turning left on the road turning left, and the going-straight vehicles deviating two lanes in the left and driving out of the intersection, so as to avoid the simultaneous passing ofthe opposite left-turning vehicles; the going-straight vehicles after entering the exit lane shifting rightwards by one lane in the left-turn vehicle lane changing zone and going straight continuously. The method is used for eliminating the left turn phase of an intersection.

Description

Technical field [0001] The invention relates to a method for eliminating the left-turn phase at an intersection, and belongs to the technical field of traffic engineering. Background technique [0002] As an important part of the urban road traffic network, road intersections are not only the bottleneck of road capacity, but also the frequent occurrence of traffic accidents. Existing road intersections usually have greater safety hazards due to many conflict points. For example, at a two-way two-lane intersection, there are 32 potential conflict points, of which 24 conflict points are related to left-turn traffic. [0003] Therefore, the left-turning vehicle at the intersection not only affects the flow of traffic in the straight direction, but also is the main factor for conflict. The flow of left-turning traffic will not only cause traffic safety problems, but also increase the number of signal phases at the intersection, to a certain extent, aggravate the traffic delay at the ...
