The intelligent lamp post is used as a part of a highway management system, and can greatly influence the management of a highway. The functions of the existing intelligent expressway street lamp generally comprise illumination, video monitoring, a signal base station and the like, the intelligent expressway street lamp is single in function, low in intelligence degree, relatively independent in functions, single in data type acquired by an auxiliary sensor and incapable of being immediately interconnected and communicated with other terminal equipment, driving convenience is provided for a driver, and the advantage of high expressway coverage mileage is not comprehensively embodied.

The expressway adopts various white marked lines specified by traffic laws and regulations, and various roadside or overhead signs or display screens to provide traffic information for drivers. In order to meet the requirements of drivers on conveniently knowing other various information such as traffic and the like when traveling, plane indication boards or display screens are erected on two sides of a highway or above the highway by related departments. However, the installation in this way is limited by installation environment and conditions, and the installation cost is high; once installed, the position, the use angle and the use area of the device can not be changed at will, the display area can not be increased or reduced along with the characteristics of the object to be displayed, and the display angle can not be adjusted, so that the requirement of a driver for timely, accurately, safely and conveniently acquiring highway traffic information can not be met.

In addition to this, large vehicles on highways are increasing due to the constant development of city economy. When the large vehicles normally run, drivers in the adjacent lanes behind the large vehicles are difficult to clearly acquire information of the signs or the display screens above the roads; the driver can be distracted by searching for related information, thereby greatly increasing the probability of causing traffic accidents. Meanwhile, the driver needs to adjust the driving route in time due to sudden road safety conditions such as vehicle accidents and the like, and the driver also needs to acquire the highway traffic information conveniently, quickly and accurately. Therefore, how to design a display method, a device and a system which can meet the requirement that a driver obtains highway traffic information on a highway is very important and has practical significance.

2. The intelligent light pole-based highway traffic information display method according to claim 1, wherein said evaluating road conditions ahead of said vehicle comprises the steps of:

determining a section of a road ahead of the vehicle;

the section of the road ahead of the vehicle includes a section of the acquired driving route of the vehicle on an expressway that the vehicle has not yet passed through, or a section of the default driving route of the vehicle on an expressway that the vehicle has not yet passed through;

3. The intelligent lamp pole-based highway traffic information display method according to claim 1, wherein the highway traffic information is displayed according to whether the road ahead is abnormal or not, comprising the steps of:

if the abnormal driving data does not exist, the vehicle normally runs;

if abnormal driving data exist, the vehicle runs to the position in front of the nearest same-direction highway exit of the road section affected by the accident, and the intelligent lamp post indicates the vehicle to the vehicle-mounted navigation system and the vehicle driver mobile terminal to avoid the accident vehicle through the highway exit;

the vehicle is gone to receiving during the highway section of accident influence, the wisdom lamp pole instructs highway ground sign screen display to show ground triangle mark, guides the vehicle dodges because of the shared lane of place ahead accident car, and/or, screen automatic indication in the middle of the vehicle lane ground the vehicle dodges and occupies the lane.

4. The intelligent lamp post-based highway traffic information display method according to claim 1, wherein before the guardrail screen displays the highway traffic information, the method further comprises the following steps:

5. An intelligent lamp pole display control device, which is used for realizing the intelligent lamp pole-based highway traffic information display method of any one of claims 1-4; its characterized in that, wisdom lamp pole display control device includes:

the judging module is used for judging whether the front road is abnormal or not; measuring and calculating the distance between two adjacent vehicles in the same lane;

6. The intelligent lamp post display control device as claimed in claim 5, applied to a smart lamp post-based highway traffic information display control device, wherein the collecting module is further configured to collect vehicle license plate information, vehicle height, and vehicle length; acquiring image information of the vehicle and adjacent vehicles thereof in real time, and determining a position relation; collecting the vehicle license plate information, the vehicle height and the vehicle length of the vehicle and the adjacent vehicles; observing the running speed of each vehicle on the road section, and automatically tracking and observing the vehicle with the running speed of zero and the vehicles in the same lane in front of and behind the vehicle; acquiring the speed of a vehicle with zero running speed and the speed of a vehicle behind the same lane;

the evaluation module is further configured to determine a segment of a road ahead of the vehicle: observing a lane occupied by a vehicle on a road section affected by the accident and evaluating; evaluating that the vehicle with zero travel speed is an accident vehicle; evaluating road sections affected by the accident; observing the lanes occupied by the vehicles on the road section affected by the accident and evaluating;

the display module is used for indicating the highway ground sign screen to display a ground triangular sign and guiding the vehicle to avoid a lane occupied by a vehicle with a front accident; the display device is also used for indicating the guardrail screen to display the highway traffic information; the guardrail screen is used for indicating the guardrail screen to adjust the angle upwards by 5-15 degrees, or the guardrail screen uses an arc screen and displays the highway traffic information through the arc part of the upper part of the arc screen;

wisdom lamp pole display control device, still include:

the calculation module is used for measuring and calculating the distance between two adjacent vehicles in the same lane; comparing the height values of two adjacent vehicles in the same lane; if the rear vehicle height value is smaller than the front vehicle height value, subtracting a rear vehicle neglected height value from the rear vehicle height value to be used as a rear vehicle driver visual field height value; and calculating the minimum distance necessary for the driver of the rear vehicle not to be shielded by the front vehicle according to the height value of the vision field of the driver of the rear vehicle, the length of the front vehicle, the distance from the front vehicle to the traffic sign above the front road surface and the height of the traffic sign above the front road surface.

7. The utility model provides a highway traffic information display system based on wisdom lamp pole which characterized in that, the system can realize including: the intelligent lamp post-based highway traffic information display method according to any one of claims 1-4.

8. An electronic device comprising a processor and a machine-readable storage medium storing machine-executable instructions executable by the processor, the processor-executable instructions, when invoked and executed by the processor, causing the processor to: the method for realizing the intelligent lamp pole-based highway traffic information display of any one of claims 1-4.
