In S102, a first image including a traffic light is extracted, and the state of the traffic light is specifically analyzed.
In S103, a straight traffic light in the traffic lights is extracted, and it is determined whether the straight traffic light has just been switched from a red light state to a green light state.
In step S104, if yes, the first image including the u-turn guide lane entrance is extracted at the same time, and the environment around the u-turn guide lane entrance is specifically analyzed.
In S105, it is determined whether or not a u-turn vehicle is present in the u-turn guide lane opening.
In S106, if no turning vehicle exists, directly controlling the rotary railing to rotate downwards for 90 degrees, and sealing the turning guide vehicle crossing; if the vehicle turns around, first prompt information is sent to the turning around, the first prompt information can be set to be 'the opening of the turning around guide lane is about to be closed', and the rotating handrail is controlled to rotate downwards for 90 degrees after the vehicle passes through the turning around.
Example two
As shown in fig. 2 and 3, S106 further includes:
acquiring a second image of the left lateral lane;
judging whether a right-turn vehicle exists on a right-turn lane of the left lateral lane;
if yes, pre-calculating a first lane to which the right-turning vehicle is about to enter;

Before sending information to the U-turn vehicle, establishing a connection relation with a control system of the vehicle entering the U-turn guide port.
Specifically, when no straight-ahead vehicle passes through the opposite lane, the rotary rail is in an upward rotation 90-degree state, and the turning-round vehicle can be guided to the lane crossing through turning round.
However, a right-turn vehicle enters the same road as the u-turn vehicle in the left lateral lane, and if the number of lanes on the road is small, the right-turn vehicle and the u-turn vehicle meet in the same lane, so that potential safety hazards are increased.
Firstly, acquiring a second image in a left lateral lane, extracting a right-turn lane, judging whether a right-turn vehicle exists in the right-turn lane, if so, analyzing a steering track of the right-turn vehicle, and pre-calculating a first lane into which the right-turn vehicle is about to enter; and then acquiring a first image including a U-turn guide vehicle road junction, judging whether a U-turn vehicle exists in the U-turn guide vehicle road junction, if so, analyzing the U-turn track of the U-turn vehicle, pre-calculating a second lane into which the U-turn vehicle is about to enter, judging whether the first lane and the second lane are the same lane, if so, establishing a connection relation with a control system of the U-turn vehicle, and sending second prompt information to the control system, wherein the second prompt information can be set as 'please notice to avoid the right-turn vehicle'.
If the first lane and the second lane are not the same lane, judging whether the second lane is positioned on the right side of the first lane, if the second lane is positioned on the right side of the first lane, indicating that a turning vehicle and a right-turning vehicle have crossed tracks and also increasing potential safety hazards, and sending second prompt information to the control system, wherein the second prompt information can be set to 'please notice to avoid the right-turning vehicle'.
