2 . The unit of claim 1 , wherein:
the roadside acquisition device comprises a traffic light controller; the traffic data comprises control information for a preset traffic light provided by the traffic light controller; and the roadside computing device is configured to determine a state of the preset traffic light according to the control information for the preset traffic light, and to generate traffic prompt information indicating the state of the preset traffic light.

3 . The unit of claim 1 , wherein:
the roadside acquisition device comprises an image acquisition device; the traffic data comprises road image information acquired by the image acquisition device; and the roadside computing device is configured to determine a road traffic condition according to the road image information, and to generate traffic prompt information indicating the road traffic condition.

4 . The unit of claim 1 , wherein:
the roadside acquisition device comprises a radar; the traffic data comprises road radar information provided by the radar; and the roadside computing device is configured to determine a road traffic condition according to the radar image information, and to generate traffic prompt information indicating the road traffic condition.

5 . The unit of claim 3 , wherein:
the traffic data further comprises image information of a preset traffic light acquired by the image acquisition device; and the roadside computing device is further configured to determine a state of the preset traffic light according to the image information of the preset traffic light, and to generate traffic prompt information indicating the state of the preset traffic light.

6 . The unit of claim 1 , wherein:
the roadside acquisition device comprises a traffic light controller, an image acquisition device and a radar; the traffic data comprises control information for a preset traffic light provided by the traffic light controller, road image information acquired by the image acquisition device and road radar information provided by the radar; and the roadside computing device is configured to:
determine a state of the preset traffic light according to the control information for the preset traffic light, and generate traffic prompt information indicating a state of the preset traffic light, and
determine a road traffic condition according to at least one selected from: the control information for the preset traffic light, the road image information, or the road radar information, and generate a traffic prompt information indicating the road traffic condition.

7 . The unit of claim 1 , wherein the roadside communication device is a roadside communication device based on LTE-V2X, 4G or 5G standards, and the roadside communication device is configured to broadcast the traffic prompt information to a communication coverage area of the roadside communication device based on LTE-V2X, 4G or 5G standards.

8 . The unit of claim 2 , wherein the roadside communication device is a roadside communication device based on LTE-V2X, 4G or 5G standards, and the roadside communication device is configured to broadcast the traffic prompt information to a communication coverage area of the roadside communication device based on LTE-V2X, 4G or 5G standards.

9 . The unit of claim 3 , wherein the roadside communication device is a roadside communication device based on LTE-V2X, 4G or 5G standards, and the roadside communication device is configured to broadcast the traffic prompt information to a communication coverage area of the roadside communication device based on LTE-V2X, 4G or 5G standards.

10 . The unit of claim 4 , wherein the roadside communication device is a roadside communication device based on LTE-V2X, 4G or 5G standards, and the roadside communication device is configured to broadcast the traffic prompt information to a communication coverage area of the roadside communication device based on LTE-V2X, 4G or 5G standards.

11 . The unit of claim 5 , wherein the roadside communication device is a roadside communication device based on LTE-V2X, 4G or 5G standards, and the roadside communication device is configured to broadcast the traffic prompt information to a communication coverage area of the roadside communication device based on LTE-V2X, 4G or 5G standards.

12 . The unit of claim 6 , wherein the roadside communication device is a roadside communication device based on LTE-V2X, 4G or 5G standards, and the roadside communication device is configured to broadcast the traffic prompt information to a communication coverage area of the roadside communication device based on LTE-V2X, 4G or 5G standards.

13 . A traffic prompt device, comprising:
a communication component configured to receive traffic prompt information sent by the roadside service unit of claim 1 ; a processor connected to the communication component and configured to generate display data according to the traffic prompt information received; and a display connected to the processor and configured to display according to the display data generated by the processor.

14 . The traffic prompt device of claim 13 , installed on a mobile public facility and/or a non-mobile public facility.

15 . The traffic prompt device of claim 14 , installed on a mobile public facility, and the display of the traffic prompt device is installed at a tail of the mobile public facility.

16 . The traffic prompt device of claim 15 , further comprising a positioning component connected to the processor, and configured to determine a position of the mobile public facility and a moving direction of the mobile public facility, and
wherein the processor is configured to generate the display data according to the received traffic prompt information in response to determining that the received traffic prompt information matches the mobile public facility according to the position of the mobile public facility and the moving direction of the mobile public facility.

17 . A traffic prompt system, comprising:
a roadside service unit comprising a roadside acquisition device, a roadside computing device and a roadside communication device, wherein the roadside acquisition device and the roadside communication device are communicatively connected with the roadside computing device, the roadside acquisition device is configured to provide traffic data, the roadside computing device is configured to generate traffic prompt information according to the traffic data provided by the roadside acquisition device, and the roadside communication device is configured to send the traffic prompt information generated by the roadside computing device to a preset area; and a traffic prompt device comprising a communication component, a processor and a display, wherein the communication component and the display are connected to the processor, the communication component is configured to receive the traffic prompt information sent by the roadside communication device of the roadside service unit,
