The interior of the bearing body 1 is hollow, so that the weight of the traffic marking device can be reduced, and the traffic marking device can be conveniently moved to a proper position at any time according to an actual environment scene.

The electronic barcode 22 generally includes a quiet zone, a start character, a data character, and a stop character. In order to attach the electronic barcode 22 to the outer surface 11 of the carrier 1 to carry information, the outer surface 11 of the carrier 1 may be partitioned according to the character structure of the electronic barcode 22.

Specifically, the outer surface 11 of the carrier 1 includes at least a first quiet zone F1, a start zone a, data zones B and C, a termination zone E, and a second quiet zone F2 along a predetermined direction, wherein the ring-shaped light-emitting bars a of different colors of the start zone a, the data zones B and C, and the termination zone E form the electronic barcode 22.

Alternatively, the first quiet zone F1 and the second quiet zone F2 have annular luminous strips with the same color, and the annular luminous strips a of the start zone a and the annular luminous strips a of the end zone E are arranged differently.

The first quiet zone F1 is for the scanner to prepare for scanning, and the second quiet zone F2 is an end mark to ensure that the scanner can properly identify the electronic barcode 22. The first quiet zone F1 is the same color as the second quiet zone F2, which ensures that the electronic barcode 22 can be scanned bi-directionally. The initial area A represents the beginning of formal reading of the code, the data areas B and C represent the main contents of the electronic bar code, for example, the data area B is a use mark code, the data area C is an information data code, and the termination area E is used for informing that the code is completely scanned. The arrangement of the annular luminous bar a of the starting area A is different from that of the annular luminous bar a of the ending area E, so that the information of the electronic bar code 22 can be automatically rearranged when the electronic bar code 22 is scanned in two directions by the scanning device.

In some embodiments, a check area D is further included between the data area C and the termination area E. The check area D is used to check whether the read data is correct, and different encoding rules may have different check rules. Thus, the ring-shaped light-emitting bars a of different colors of the start area a, the data areas B and C, the verification area D, and the end area E together form the electronic bar code 22.

Optionally, the traffic scene mark 21 is located in the first quiet zone F1 or the second quiet zone F2 of the electronic barcode 22; alternatively, the traffic scene mark 21 is located in the first quiet zone F1 and the second quiet zone F2 of the electronic barcode 22.
