Fig. 1 is a flowchart of a first embodiment of a traffic scheduling implementation method according to the present invention, where the traffic scheduling implementation method of the embodiment is applied to an ETC roadside device, and specifically includes the following steps:
s11, receiving traffic scheduling information issued by a traffic scheduling center;
in this step, the traffic scheduling center collects traffic scheduling information in real time, where the traffic scheduling information includes, but is not limited to, a road traffic control center, a traffic light status, or an implementation situation where an additional camera (which may also be integrated in the ETC roadside device) is added to obtain the current road, and the like. Moreover, the ETC roadside device is provided with a receiving module, such as a wired receiving module or a wireless receiving module, so that the traffic dispatching center can send the collected traffic dispatching information to the ETC roadside device in real time.
For example, the traffic scheduling information may be dangerous road condition warning information, such as broadcasting sudden dangerous conditions of a road, such as landslide, falling rocks, accumulated water, and the like in advance, and also including fixed dangerous road conditions, such as sharp turns, steep uphill slopes, steep downhill slopes, and the like; lane change early warning information can also be included, including construction of a front lane, temporary closure of the lane, narrowing of the lane and the like; the vehicle-mounted intelligent traffic light early warning system can also be red light early warning information so as to prevent the corresponding vehicle from running the red light by mistake under the condition that the corresponding vehicle is shielded by a large vehicle or in severe weather; the road congestion warning information can also be road congestion warning information, and if the traffic congestion occurs on the road ahead, the vehicle about to pass through the place is reminded to select the road to drive; and can also be restricted road reminding information and the like. It should be understood that the above examples are for illustrative purposes only and are not to be construed as limiting in any way.
And S12, sending the traffic scheduling information to an ETC electronic tag by adopting DSRC so that a vehicle provided with the ETC electronic tag outputs the traffic scheduling information.
In the step, the ETC roadside device sends the traffic scheduling information to the ETC electronic tag through the DSRC signal in real time, and the ETC electronic tag can receive the traffic scheduling information and then output the traffic scheduling information, so that a vehicle user can obtain the traffic scheduling information.
Through the technical scheme of the embodiment, on the basis of the existing ETC application platform, the timely, accurate and effective issuing of the traffic scheduling information can be realized, the difficult problem on the scheme is solved, and meanwhile, the input cost of the project is greatly reduced.
