Technical Field

Background
Urban road intersections are the key places for congestion. Particularly, at the intersection, vehicles in each direction turn left or go straight at the intersection and flow in other directions generate four intersections, so that the vehicles in all directions can sequentially pass through the intersection only by means of the fact that the signal lamps need to turn left longitudinally, go straight longitudinally, turn left transversely and go straight transversely and release for four times. The number of the passing vehicles is certain in each lane in unit time. In order to increase the total number of vehicles passing through the intersection within the limited time of the green light, the existing method is to increase the number of lanes at the intersection, such as adding a left-turn lane, or using an opposite lane to add a left-turn lane in a variable lane manner. The passing rate is improved to a certain extent. But simultaneously, the intersection is enlarged invisibly, the passing time is increased, and the benefit brought by increasing the number of lanes is weakened. At present, no effective management mode is available for solving the congestion problem.

Detailed Description
The invention will be described in further detail below with reference to the drawings and specific examples.
The first embodiment is as follows:
fig. 1 shows an embodiment of the road intersection structure of the invention, the road intersection structure comprises four bidirectional roads 1, each bidirectional road 1 is intersected to form an intersection 2, the middle parts of the opposite bidirectional roads 1 near one end of the intersection 2 are respectively provided with a turning waiting area 3, the turning waiting areas 3 are parking waiting areas for turning of vehicles on the inner lanes of the opposite bidirectional roads 1, and the bidirectional roads 1 are provided with stop lines 4 at one sides of the turning waiting areas 3 far away from the intersection 2.
Because the middle part of the end, close to the intersection 2, of the opposite two-way road 1 is provided with the turning waiting area 3, after the vehicle on the inner side lane runs to the opposite turning waiting area 3, the turning waiting indication is performed again, after the vehicle in each turning waiting area 3 receives the release indication, the vehicle turns simultaneously, or the vehicles in the two turning waiting areas 3 in one direction (the first direction 6 or the second direction 7) turn simultaneously, namely, the vehicle on the inner side lane turns after passing through the intersection 2 in a straight line, so that the cross blocking does not occur during the turning simultaneously, the passing efficiency of the vehicles at the intersection is improved, the waiting time is shortened, and the intersection is prevented from being blocked.
In the embodiment, the side of the bidirectional road 1 is provided with a turn signal lamp 5 for indicating the turning of the vehicle in the turning waiting area 3. Whether the vehicles in the turning waiting area 3 are released or not is indicated through the turning signal lamp 5, and the vehicles in the inner lane are prevented from being blocked in a crossing way with the straight vehicles on the opposite lane when turning.
In this embodiment, a plurality of parking spaces 31 are provided in the turning waiting area 3, and a turning guide line 32 is provided in each parking space 31. Each parking space 31 can park one vehicle, so that the indication and the vehicle displacement are convenient, and the turning vehicle is prevented from being mistakenly stopped in the turning waiting area 3.
In the present embodiment, the parking space 31 is a parallelogram. Specifically, two adjacent sides of the parking space 31 are respectively 5.5 meters and 5 meters long, so that the turning vehicle can conveniently rotate by an angle in advance after entering the parking space 31, and preparation is made for subsequent turning. The long side of the parking space 31 forms an angle of 65 degrees with the straight direction of the two-way road 1. The turning waiting area 3 can occupy part of the inner lane, but does not influence the passing of the vehicles in the inner lane.
In this embodiment, the number of the bidirectional roads 1 is four, and the four bidirectional roads 1 cross each other. The middle parts of the ends, facing the intersection 2, of the four bidirectional roads 1 are provided with turning waiting areas 3.
Example two:
fig. 2 shows another embodiment of the road intersection structure of the invention, the road intersection structure of the embodiment includes three bidirectional roads 1, each bidirectional road 1 is crossed in a t shape and meets to form an intersection 2, the middle parts of the two opposite bidirectional roads 1 near one end of the intersection 2 are respectively provided with a turning waiting area 3, the turning waiting areas 3 are parking waiting areas for turning of vehicles on the inner lanes of the two opposite bidirectional roads 1, and the two-way roads 1 are provided with stop lines 4 on one sides of the turning waiting areas 3 far away from the intersection 2. Specifically, since there are only three bidirectional roads 1, the opposite bidirectional roads 1 are two bidirectional roads 1 in the same direction (the second direction 7 shown in fig. 2, which may also be referred to as an east-west direction), and the remaining one bidirectional road 1 (the bidirectional road 1 in the first direction 6 shown in fig. 2) has no opposite lane, so that there is no need to provide the turning waiting region 3 for turning the inside vehicle of the opposite lane.
Because the middle part that relative two-way road 1 is close to 2 one end in the crossing all is equipped with the turn and treats the district 3 of going, after the vehicle on the inboard lane went to the turn of opposite side and treats the district 3 of going, wait for the turn instruction again, the vehicle in each turn treats the district 3 and receives the clearance instruction back, turn simultaneously, promptly, interior lane vehicle turns again after straight passing through crossing 2 to do not take place alternately when turning simultaneously and block, improved crossing vehicle's traffic efficiency, reduced latency, prevent crossing jam.
Example three:
a vehicle passing method of a road intersection structure in an embodiment I comprises the following steps:
s1: the bidirectional road 1 in the first direction 6 is released first: the two bidirectional roads 1 in the first direction 6 go straight and go, the two turning waiting areas 3 in the first direction 6 stop going, the two bidirectional roads 1 in the second direction 7 go straight and stop going, and the two turning waiting areas 3 in the second direction 7 go;
s2; two-way road 1 in second direction 7 is released: when the time length T1 elapses, the two bidirectional roads 1 in the first direction 6 go straight and stop releasing, the two turning waiting areas 3 in the first direction 6 release, the two bidirectional roads 1 in the second direction 7 go straight and release, and the two turning waiting areas 3 in the second direction 7 stop releasing;
s3: after the time period T2 elapses, step S1 is performed.
Taking the first direction 6 as the north-south direction and the second direction 7 as the east-west direction as an example: firstly, turning signal lamps 5 of a turning waiting area 3A and a turning waiting area B in the south-north direction are changed into red lamps, turning signal lamps 5 of a turning waiting area C and a turning signal lamp D in the east-west direction are green lamps, a turning two-way straight-going signal lamp in the south-north direction is changed into green lamps, an east-west two-way straight-going signal lamp is a red lamp, namely, vehicles in the turning waiting area 3C and the turning waiting area D pass, the east-west two-way straight-going vehicles stop passing, and vehicles in the turning waiting area 3A and the turning waiting area B stop passing; then, the turn signal lamps 5 of the turning waiting areas 3 of the numbers A and B are green lamps, the turn signal lamps 5 of the turning waiting areas 3 of the numbers C and D are red lamps, the south-north two-way straight running signal lamps are red lamps, the east-west two-way straight running signal lamps are green lamps, namely, east-west two-way straight running vehicles pass through, the turning waiting areas 3 of the numbers A and B pass through, the south-north two-way straight running vehicles stop passing through, and the turning waiting areas 3 of the numbers C and D stop passing through; thereby beginning to enter the cycle.
The intersection only allows the vehicles running straight in the south and north directions and the vehicles running straight in the east and west directions to pass through; the left-turning vehicles in all directions and the straight-going vehicles in all directions do not intersect any more; the intersection does not need to separately distribute left-turn passing time, and only needs to distribute twice straight passing time, so that the passing efficiency is greatly improved, and the waiting time is reduced.
According to the vehicle passing method, in two time periods (T1 and T2) in one cycle, no matter the vehicles go straight or turn in the inner lane, the vehicles pass through one time period (specifically shown in the following table I) and pause for one time period, so that the passing efficiency of the vehicles at the intersection is improved, the waiting time is shortened, and the intersection is prevented from being jammed.
