[0051] The present invention is further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0052] Poor lighting conditions in nighttime construction scenes and reduced visual discrimination ability of drivers are the main causes of traffic accidents. By scientifically and rationally setting up traffic safety facilities such as roadblocks and temporary lighting, drivers can be effectively reminded of special situations ahead and vehicles can be guided to safely pass through construction areas or accident-prone areas. At the same time, drivers' perception of road conditions can be significantly improved, thereby preventing accidents caused by poor visibility. In addition, reasonably arranged roadblocks can also play a role in physical isolation, preventing vehicles from mistakenly entering the construction area and ensuring the safety of construction workers and passing vehicles. Therefore, a scientific layout plan for traffic safety facilities can greatly improve the nighttime driving environment, reduce the incidence of traffic accidents, and ensure smooth and safe road traffic.

[0053] In order to improve traffic safety and strengthen traffic management during nighttime construction, the embodiment of the present invention provides a method for deploying safety facilities and hazard warning in nighttime construction scenarios, such as Figure 1 As shown, the method comprises the following steps:

[0054] S10. Obtain nighttime construction scene information.

[0055] Here, the nighttime construction scene information includes: road speed limits on the construction sections, average daily traffic volume, and average vehicle speed.

[0056] In practice, by deploying various sensors, cameras, smart terminals and other equipment on the construction road section and connecting them to the communication network, the above-mentioned various nighttime construction scene information can be collected in real time. In addition, for information such as the average daily traffic volume and the average vehicle speed, the daily average traffic volume and the average vehicle speed can be statistically analyzed by a large amount of acquired data, so that the statistically analyzed daily average traffic volume and the average vehicle speed are used as the daily average traffic volume and the average vehicle speed to be acquired in step S10.

[0057] S20. According to the nighttime construction scene information, a warning area, an upstream transition area, a buffer area, a construction operation area, a downstream transition area, and a termination area are planned.

[0058] See also Figure 2 As shown, the warning zone is used to warn drivers entering the zone, reminding them that they are about to enter the construction section. Therefore, work area distance signs, speed limit signs, road construction signs ahead, and smart signs can be placed in the warning zone to remind drivers that they are about to enter the construction area ahead. The role of the upstream transition zone and the downstream transition zone is to provide a smooth transition zone between the normal driving lane and the construction area, to ensure that the traffic flow can adjust the direction of travel in time and reduce the possibility of accidents. The role of the buffer zone is to provide additional safety protection for workers on the construction site. It allows drivers to have more reaction time and reduces the risk of accidents caused by accidents or driver distraction. The construction area is the area where construction workers are working. If a vehicle accidentally enters this area, it will pose a threat to the personal safety of the construction workers. The role of the termination zone is to remind vehicle drivers that they are about to leave the construction section.

[0059] In step S20, the warning zone, upstream transition zone, buffer zone, construction work zone, downstream transition zone and termination zone are planned according to the nighttime construction scene information, including: determining the area lengths of the upstream transition zone, buffer zone, work zone and downstream transition zone according to the road speed limit of the construction section, the average daily traffic volume and the average vehicle speed; and planning the upstream transition zone, buffer zone, work zone and downstream transition zone according to the lengths of each area.

[0060] It is understandable that the larger the daily average traffic volume and the faster the speed, the longer the distance required for traffic speed adjustment and lane adjustment. Therefore, the length of each area can be reasonably set based on the daily average traffic volume and the average vehicle speed, combined with the road speed limit regulations. For example, the warning area can be decelerated at a speed limit of 20 kilometers per hour per 200 meters in accordance with relevant standards, and the specific length can refer to the overall road speed limit.

[0061] Then, according to the length of each area set, refer to Figure 2 The areas are arranged in the order shown, and the warning area, upstream transition area, buffer area, construction area, downstream transition area and termination area are planned in sequence.

[0062] S30. Safety facilities are deployed in the warning area, upstream transition area, buffer area, construction area, downstream transition area and termination area; the safety facilities include: smart road cones, smart warning lights and smart signboards.

[0063] It is understandable that the warning area is used to alert drivers entering the area that they are about to enter a construction section. Therefore, work area distance signs, speed limit signs, road construction signs ahead and smart signs can be placed in the warning area to remind drivers that they are about to enter a construction area.

[0064] Ways to deploy safety facilities in the upstream / downstream transition zone include:

[0065] (1) Install smart signboards at the start and end of the upstream / downstream transition zone;

[0066] Here, the smart signboard at the starting position of the upstream transition zone is used to guide the driving direction, and the smart signboard at the ending position of the upstream transition zone is used as a working distance sign to remind the driver that he is about to enter the construction area. The smart signboard at the starting position of the downstream transition zone is used to guide the driving direction, and the smart signboard at the ending position of the downstream transition zone is used to remind the driver that he has left the construction area and is about to leave the buffer zone.

[0067] According to the "Highway Maintenance Safety Operation Procedures", the spacing of isolation equipment in the upstream transition zone should not be greater than 4 meters. Therefore, the spacing of equipment in the upstream transition zone can be determined in combination with the detection radius of the smart cone barrel. At the same time, they are arranged at equal intervals along the diagonal line to separate the lanes. At the same time, linear induction signs and smart signs are set at the starting and ending positions of the upstream transition zone to guide the direction of traffic and give drivers corresponding prompts.

[0068] (2) multiple smart cones are arranged between the starting position and the ending position of the upstream / downstream transition zone;

[0069] like Figure 2As shown in , multiple smart cones are arranged at equal intervals along the diagonal line between the starting position and the ending position. According to the Highway Maintenance Safety Operation Regulations, the spacing between the smart cones arranged between the starting position and the ending position of the upstream transition zone is ≤4 meters. The spacing between the smart cones arranged between the starting position and the ending position of the downstream transition zone is ≤10 meters.

[0070] The buffer zone is mainly used to prevent vehicles from entering the construction area and to protect the safety of personnel in the construction area. Therefore, the safety facilities deployed in the buffer zone are mainly smart cones. By reasonably setting the deployment points of smart cones in the buffer zone, the above purpose can be better achieved.

[0071] Specifically, the ways to deploy safety facilities in the buffer zone include:

[0072] (1) Determine the number N of smart cones to be deployed in the buffer zone.

[0073] Here, the value of N is specified in advance.

[0074] (2) Taking maximizing the coverage of the buffer zone by smart cones as the optimization goal, the sparrow search algorithm is used to search for the deployment points of N smart cones in the buffer zone to obtain the optimal deployment points;

[0075] Here, the coverage rate of the smart cone bucket to the buffer zone is specifically the coverage rate of the detection range of N smart cone buckets to the buffer zone.

[0076] (3) Deploy N smart cones in the buffer zone according to the optimal deployment points;

[0077] (4) Use multiple smart cones to separate the buffer area from the work area.

[0078] Specifically, smart cones are used to separate the end of the buffer zone and the beginning of the construction area, so as to determine whether a vehicle intrusion is detected by whether the smart cones sense a collision.

[0079] In one implementation, maximizing the coverage of the buffer zone by the smart cones is taken as an optimization goal, and the layout points of N smart cones in the buffer zone are searched using a sparrow search algorithm to obtain the optimal layout points, including:

[0080] (2-1) Divide the buffer into L×M grids;

[0081] Specifically, the starting point of the buffer zone is used as the coordinate origin to establish a coordinate system. i The coordinates are expressed as (x i ,y i ), the jth intruder T j The coordinates are expressed as (x j ,yj ), i = 1, 2, ..., N, j = 1, 2, ..., N. Then, the entire buffer zone is divided into L × M grids, so that the smart cone barrels and the targets that break into the buffer zone (such as intruding vehicles) are all located in the grids.

[0082] (2-2) The Boolean model is used to construct a probability model of the intruder being detected by a single smart cone bucket:

[0083]

[0084] Among them, d(Z i ,T j ) represents the i-th smart cone bucket Z i and the jth intruder target T j The distance between R s is the radius of the detection coverage of the smart cone barrel. Here, the detection coverage of the smart cone barrel is modeled as a circular area with a fixed radius. i ,T j ) indicates breaking into target T j By Smart Cone Bucket Z i The probability of detection is assumed here that the probability of detecting an intruder within the detection coverage of the smart cone is 1, and the probability of detecting an intruder outside this range is 0.

[0085] (2-3) Based on the probability model, a joint probability model is constructed for all smart cone buckets to perform collaborative detection on intrusion targets:

[0086]

[0087] Among them, p(Z,T j ) represents the joint probability of the intrusion target Tj being collaboratively detected by all smart cone buckets.

[0088] (2-4) Based on the joint probability model, an objective function is constructed with the goal of maximizing the coverage of the buffer zone by the smart cone bucket:

[0089]

[0090] Among them, Re cov Indicates the coverage rate, which means the ratio of the number of grids covered by all smart cones to the total number of grids in the buffer zone.

[0091] (2-5) According to the objective function, the sparrow search algorithm is used to search for the deployment points of N smart cone barrels in the buffer zone to obtain the optimal deployment points. Figure 3 A flow chart of searching for optimal layout points using the sparrow search algorithm is shown.

[0092] The ways to deploy safety facilities in the construction area include: setting up a number of smart cones at intervals of no more than 4 meters to separate lanes in the construction area, and deploying smart warning lights at intervals of no more than 20 meters.

[0093] In one embodiment, the safety facility further comprises: a sound alarm device; therefore, a sound alarm device, such as a small safety horn, may be arranged at intervals of no more than 20 meters in the construction area. Figure 4 As shown, the smart warning lights and sound alarm devices can share a set of power supply and communication and control units, which can also save costs and the number of safety facilities that need to be deployed in the buffer zone.

[0094] It is understandable that the construction area is an area where construction workers are concentrated. In order to ensure the personal safety of construction workers in a night environment, it is necessary to reasonably arrange safety facilities in the work area, among which the safety facilities that need to be arranged are mainly lane separation and early warning reminders. According to the length of the construction area and the standards of the "Highway Maintenance Safety Operation Regulations", that is, the spacing between isolation equipment is not more than 4 meters, the number of smart cones is reasonably set and placed at equal intervals along the rectangular boundary of the construction area for lane separation. According to the "Highway Maintenance Safety Operation Regulations" (JTG H30-2015) standards, the spacing between lighting warning equipment should not be greater than 20 meters, so smart warning lights are also used to set up at equal intervals of no more than 20 meters on the rectangular boundary of the construction area for lighting guidance and early warning reminders.

[0095] In this way, when no dangerous situations such as vehicles breaking into the construction area are detected, the color of the smart warning light remains in a safe state and continues to illuminate; when the smart cone barrel detects a dangerous situation, the color of the smart warning light changes to a warning state and the safety loudspeaker is activated to broadcast the warning level and response measures.

[0096] The purpose of the termination zone is to remind vehicle drivers that they are about to leave the construction section, so only prompt signs such as speed limit removal signs need to be set up.

[0097] S40. Monitor the nighttime construction scene through safety facilities and implement danger warning based on the monitoring information.

[0098] After completing the layout of several major construction areas such as warning areas, transition areas, buffer areas, and work areas, the overall nighttime construction safety management system is deployed, and all intelligent safety facilities in the above nighttime construction areas are interconnected through wireless networks and uniformly managed and dispatched by the nighttime construction safety management system. The system is used to record and analyze monitoring information; when a dangerous situation is found through the analysis of monitoring information, the sound alarm device and the smart warning light are used to issue a danger warning.

[0099] For details, see Figure 5 , the safety management system mainly monitors the equipment environment, operating status and other data reported by each smart device and generates log records for subsequent equipment maintenance and accident investigation. At the same time, the system background can analyze the monitored information according to the pre-set analysis rules, so as to timely warn and notify relevant management personnel when an accident is detected, so as to ensure the safety of life and property of all parties in night construction scenes. For example, after the smart cone barrel detects a collision, the smart cone barrel reports the abnormality to the system background. After receiving the report, the system sends a warning instruction to the smart warning light to represent the vehicle intrusion, and triggers the broadcast to notify the construction area management personnel to check the accident, and notify the construction area management personnel to organize the construction personnel for emergency evacuation to prevent more serious accidents.

[0100] In addition, if there are anomalies in the uploaded device data of the intelligent safety facilities, the safety management system can also send relevant alarms to system managers and traffic management personnel, reminding managers to deal with possible anomalies in a timely manner to ensure that the system can monitor and warn normally.

[0101] In summary, the safety facility deployment and danger warning method for night construction scenarios provided by the embodiments of the present invention scientifically deploys safety facilities (such as smart road cones, smart warning lights, and smart signs) for night construction scenarios, and monitors the construction scenes through these safety facilities. Potential dangers can be quickly identified based on the monitoring information, and warnings can be issued to vehicles coming from behind on the construction road while reminding construction personnel, thereby ensuring traffic safety in the night construction area.

[0102] The embodiment of the present invention provides a specific safety facility deployment plan for nighttime construction areas. By combining traffic road information and relevant standards, based on multi-device linkage, and using Internet of Things technology to reasonably deploy smart cones and other intelligent safety facilities, not only signs are deployed in transition areas to remind vehicles, but also warning lights are used in the work area to remind construction personnel, thereby improving the safety of the overall system and enriching the safety equipment deployment method in nighttime construction scenarios. In the face of problems such as vehicles accidentally entering the construction area during construction, the system can detect in time and make timely warnings and reminders to vehicles coming from behind and construction personnel in front, thereby protecting the lives and property of relevant personnel, which is conducive to improving nighttime traffic safety and strengthening nighttime traffic management.
