What is the meaning of the following traffic sign?

- Correct answer: Traffic directions for the lanes of the next intersection.
- One-way road ahead.
- Public transportation is prohibited to proceed forward.
- Vehicles on the right lane are prohibited to deviate to another lane.
Why this is the answer
The correct answer in the official bank: Traffic directions for the lanes of the next intersection.
The sign shows an arrow for each lane, and so defines which direction you may drive from each lane: left, straight or right. Choose the lane that suits your direction of travel well in advance. The sign does not mark a one-way road and does not prohibit moving between lanes.
