[0016] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the concept or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary in nature and not restrictive.

[0017] To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the related technologies of the embodiments of the present application. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0018] Terminology explanation:

[0019] 1. Automated traffic dispatch station: referred to as automated traffic dispatch station, refers to a facility that uses automation technology and intelligent systems to monitor, manage and dispatch highway traffic. Automated traffic dispatch stations integrate various advanced sensors, data processing systems and communication technologies to achieve real-time monitoring and management of traffic flow, vehicle speed, road conditions, etc., thereby optimizing traffic dispatch and improving road traffic efficiency and safety. As a traditional fixed traffic dispatch station, the types of equipment that can be used in automated traffic dispatch stations include coils, geomagnetic, microwave, ultrasonic, infrared, video, laser, etc. The collected data include vehicle model identification, flow, location speed, headway, following percentage, headway, time occupancy, etc., and can be connected to the Internet to transmit traffic data to the traffic dispatch data center in real time. The content and format of the transmitted data should meet the requirements of industry standards. When building an automated traffic dispatch station, functions such as video monitoring, meteorology, and axle load weighing can be expanded according to needs to form a multifunctional highway traffic dispatch station.

[0020] 2. Off-site enforcement station: Off-site enforcement station is a system that uses modern technology to monitor and punish traffic violations, usually without the need for law enforcement officers to be on site. It automatically detects, records and handles traffic violations such as speeding, running red lights, illegal parking, etc. through various sensors, cameras and data processing systems installed on the road, and saves evidence of violations such as photos, videos, speed records, etc., analyzes violation data, generates statistical reports, and helps traffic management departments develop more effective traffic management strategies.

[0021] 3. Multi-source data intermodulation station: The multi-source fusion intermodulation station utilizes existing field detection equipment such as off-site law enforcement stations, bridge axle load detection, and video structured systems to obtain intermodulation data through processing and conversion, and can transmit it to the intermodulation data center in real time through the data interface.

[0022] 4. Electronic Toll Collection (ETC) on highways: ETC on highways can collect vehicle information (license plate number, vehicle type, color, brand), vehicle traffic data (travel time, travel location, driving direction), vehicle speed and driving status, etc., provide accurate toll collection services and comprehensive traffic management support, and improve the level of intelligent traffic management.

[0023] At present, the traffic control and collection network is mainly composed of automated traffic control stations and highway ETC, which are mainly deployed on national highways and key provincial roads, connecting major ports, city entrances and exits, tourist attractions, logistics parks, key mineral resource areas, provincial and municipal boundaries and national borders, etc., reflecting the characteristics of national and provincial road network traffic distribution and composition, highway service level, and transportation economic operation.

[0024] However, with the rapid development of the economy, the construction of a large number of new highway projects will lead to changes in the road network structure. Taking into account factors such as policy influence, the traffic flow of sections with large traffic flow may decrease, while the traffic flow of sections with small traffic flow may increase, which will lead to a large change in the proportion of traffic flow in each section in the region. The original traffic control stations arranged according to factors such as section traffic flow in the original traffic control collection network may be difficult to meet the actual needs of traffic control data collection and traffic dispatch. It is necessary to evaluate the layout effect of traffic control stations in the traffic control collection network, and to update the traffic control collection network by building new traffic control stations, so as to meet the needs of traffic control data collection and traffic dispatch.

[0025] Figure 1 It is a flowchart of a method for constructing a highway traffic acquisition network according to an embodiment of the present application, including:

[0026] Step S110, determining at least one layout effect parameter of an intermodulation acquisition network in a target area, wherein the intermodulation acquisition network in the target area includes at least one original intermodulation station.

[0027] Here, the original intermodulation station may include the existing automated intermodulation stations and highway ETC in the region, and the layout effect parameters are used to test the layout effect of the intermodulation stations in the intermodulation acquisition network.

[0028] Considering that the layout of traffic control stations should be based on the perspective of comprehensively reflecting the traffic volume and traffic status of the road section, full consideration should be given to factors such as road network layout planning to ensure that their distribution on the road section is uniform, representative and reasonable.

[0029] Exemplarily, the layout effect parameters may include observed mileage coverage and mileage layout density. Determining at least one layout effect parameter of the intermodulation acquisition network in the target area in step S110 includes:

[0030] Determine the observation mileage coverage rate based on the road mileage of each observation section in the cross-modulation acquisition network and the total road mileage of the target area; and,

[0031] The mileage layout density is determined based on the number of original intermodulation stations in the intermodulation collection network and the total road mileage in the target area.

[0032] Here, the observation section refers to the section whose traffic data can be obtained. The acquisition method can be direct acquisition, such as obtaining through an exchange station arranged on the section, or indirect acquisition through calculation. For example, there is no exchange station arranged on the section, but other sections associated with the section are arranged with exchange stations, and the traffic data of the section can be calculated through the traffic data on other sections. In this case, although there is no exchange station arranged on the section, the section still belongs to the observation section.

[0033] Among them, the observation mileage coverage rate β can be calculated by formula (1):

[0034]

[0035] Where, L′ represents the observed mileage, that is, the sum of the road mileages observed by each original intermodulation station in the intermodulation acquisition network, unit: km; L represents the total road mileage in the target area, unit: km.

[0036] The mileage layout density m can be calculated by formula (2):

[0037]

[0038] Where, N represents the total number of original traffic stations in the target area, unit: number; L represents the total mileage of roads in the target area, unit: km.

[0039] By calculating the observation mileage coverage of the intermodulation acquisition network, we can obtain the observation coverage of the original intermodulation stations in the intermodulation acquisition network for the existing road sections in the target area. By calculating the mileage layout density of the intermodulation acquisition network, we can evaluate whether the distribution of each original intermodulation station is reasonable in the current road network structure, thereby determining the current intermodulation acquisition network’s effect on traffic data detection in the target area.

[0040] Exemplarily, the deployment effect parameter may also include a proportion of high-traffic intermodulation stations. The step S110 of determining at least one deployment effect parameter of the intermodulation acquisition network in the target area may also include:

[0041] According to the daily average traffic volume of the traffic collection network, the average traffic volume of each original traffic station is determined;

[0042] According to the actual daily average traffic volume and mean traffic volume of each original traffic station, the number of high-flow traffic stations in the original traffic station is determined, wherein the high-flow traffic station is the original traffic station whose actual daily average traffic volume is greater than the mean traffic volume;

[0043] Determine the proportion of high-flow intermodulation stations based on the number of high-flow intermodulation stations and the number of original intermodulation stations.

[0044] Here, considering that high-flow sections are the sections that the intermodulation collection network should focus on collecting and evaluating in the road network structure, and the size of traffic flow is also an important consideration when laying out intermodulation stations, ideally, the actual traffic flow of the sections where each intermodulation station in the intermodulation collection network is located should be greater than the average traffic flow of each section in the target area. Intermodulation stations that meet this condition can be regarded as high-flow intermodulation stations. The proportion of high-flow intermodulation stations in the intermodulation collection network can be calculated to evaluate the traffic data detection effect of the current intermodulation collection network on the target area.

[0045] Among them, the proportion of large flow rate modulation stations η can be calculated by formula (3):

[0046]

[0047] Where N′ is the number of traffic stations in the target area where the actual daily average traffic volume is greater than the mean traffic volume, in units of pieces; N represents the total number of original traffic stations in the target area, in units of pieces.

[0048] Step S120, when any deployment effect parameter does not meet the corresponding index, an intermodulation station is added in at least one non-observation section of the target area to update the intermodulation acquisition network of the target area, wherein the non-observation section is a section in the intermodulation acquisition network that cannot be observed by the original intermodulation station.

[0049] Here, indicators are set for the above-mentioned deployment effect parameters respectively, so as to judge whether the data collection effect of the intermodulation collection network meets the requirements based on the comparison between the calculated deployment effect parameters and the corresponding indicators.

[0050] The embodiment of the present application is configured to determine that the data acquisition effect of the intermodulation acquisition network does not meet the demand when any deployment effect parameter does not meet the corresponding indicator, and the intermodulation acquisition network needs to be updated. In practical applications, the judgment criteria may also be adjusted. For example, at least two or three deployment effect parameters do not meet the corresponding indicators or these deployment effect parameters are graded. When a high-priority deployment effect parameter does not meet the corresponding indicator or multiple low-priority deployment effect parameters do not meet the corresponding indicator, the intermodulation acquisition network needs to be updated.

[0051] It is understandable that the three deployment effect parameters mentioned in this application are not the only way to evaluate the intermodulation acquisition network. Other parameters that can reflect the data collection effect of the intermodulation station in the intermodulation acquisition network can also be added for evaluation. This application is not limited to this.

[0052] Exemplarily, in step S120, adding an intersection station in at least one non-observation road section in the target area includes:

[0053] At least one target road section where an additional traffic control station is required is determined among the non-observation road sections in the target area; and an additional traffic control station is added to the at least one target road section.

[0054] Here, corresponding to the aforementioned observed road section, the non-observed road section refers to a road section in the target area whose traffic data cannot be obtained.

[0055] When updating the intermodulation stations in the intermodulation collection network, it is necessary to cover as many road sections and traffic nodes in the road network as possible to ensure the accuracy and reliability of the collected traffic data, and to ensure that the road sections where the intermodulation stations are located are independent of each other, so as to prevent repeated collection of information and excessive redundancy. Repeated collection can be understood as the traffic data of the road sections where the intermodulation stations are located can be obtained through calculation and processing of the traffic data of other road sections where the intermodulation stations are located, which constitutes repeated collection and intermodulation station redundancy.

[0056] Therefore, when updating the traffic acquisition network, it is not necessary to add traffic stations to all non-observation sections, but to select some target sections among these non-observation sections to add traffic stations, so as to cover as many sections and traffic nodes as possible and avoid redundancy.

[0057] The embodiment of the present application proposes an objective function for avoiding redundant deployment of intermodulation stations. The mathematical expression of the function is as shown in formula (4):

[0058]

[0059] Where f1 represents the total number of exchange stations in the region; N represents the number of road sections in the region; i represents the i-th road section, and xi represents the exchange station arranged in the i-th road section.

[0060] In order to understand the layout effect that this function wants to achieve, Figure 2 As an example, a schematic diagram of the distribution of intermodulation stations in a sub-area of ​​the target area is shown.

[0061] like Figure 2 As shown in the figure, there are 19 sections and 13 nodes in the road network structure of this sub-area, among which nodes a and b are traffic generating points, nodes c and d are traffic attracting points, and the remaining nodes are intermediate nodes. The flow on the section with the exchange station is v1=775, v2=425, v3=459, v4=341, v5=840, v7=868, v8=3, v9=392, v12=144, v15=214. According to the conservation relationship of section flow, that is, the flow into the node is always equal to the flow out of the node, the flow of the section without the exchange station can be calculated, that is, v6=394, v10=476, v11=786, v13=591, v14=147, v16=409, v17=31, v18=394, v19=591.

[0062] Therefore, by deploying interchange stations on some sections of the road, the traffic flow of all sections of the road network can be obtained, and the calculated traffic flow is unique. There are 19 sections in the road network. If interchange stations are deployed on at least 10 sections, the observability of the traffic flow of the entire road network in this sub-area can be achieved.

[0063] Exemplarily, determining at least one target section where an additional traffic control station is required in each non-observation section in the target area further includes:

[0064] At least one target section is determined in each non-observation section according to importance parameters of each non-observation section, wherein the importance parameters include section grade, number of lanes in the section, section length, section width, and section traffic capacity.

[0065] Here, the present application also proposes an objective function for maximizing the important sections of the laid-out road sections. The mathematical expression of the function is as shown in formula (5):

[0066]

[0067] Where f2 represents the sum of the importance of the layout sections; w i Indicates the importance weight of the road segment.

[0068] Among them, different weights can be assigned to each importance parameter of the road section, and the importance weight value of the road section can be calculated based on each importance parameter combined with the weight. The importance parameter here is the importance parameter of the road section in the sub-region (smaller range). If the cross-provincial cross-regional traffic collection network is evaluated, it can also be further combined with the regional population, regional gross domestic product GDP, regional per capita income, local fiscal revenue, regional road mileage, regional passenger volume, regional freight volume, etc. of different regions.

[0069] Preferably, a mathematical model can be constructed by combining the objective functions of the two dimensions in formula (4) and formula (5) to obtain the optimal solution of the mathematical model, so that the intermodulation stations in the updated intermodulation acquisition network are not redundantly arranged and are arranged in important sections as much as possible.

[0070] According to the method of the embodiment of the present application, when the intermodulation acquisition network needs to be updated, the optimal way to add intermodulation stations can be obtained by combining objective functions of different dimensions, taking into account both the deployment cost and the deployment effect.

[0071] Exemplarily, in step S120, adding an exchange station to at least one target road section includes:

[0072] Based on the traffic data monitored by other traffic monitoring facilities in the target road section, the type of the additional exchange station is determined, and the types of exchange stations include multi-source data exchange stations and automated exchange stations; based on the determined type of exchange station, an additional exchange station is added to the target road section.

[0073] Among them, the type of traffic control station to be added is determined based on the traffic data monitored by other traffic monitoring facilities in the target section, including:

[0074] When the traffic data monitored by other traffic monitoring facilities in the target road section meets the target intermodulation data of the intermodulation collection network, the type of the intermodulation station to be added is determined to be a multi-source data intermodulation station, wherein the target intermodulation data at least includes the road section traffic volume, the road section vehicle speed and the road section vehicle type; otherwise, the type of the intermodulation station to be added is determined to be an automated intermodulation station.

[0075] Here, other traffic monitoring facilities can include off-site enforcement stations, bridge axle load detection, video structured systems, etc. Since the automated traffic control station can make full use of existing data resources in the industry and its construction cost is much lower than that of the automated traffic control station, after determining the target sections where traffic control stations need to be added, it is necessary to evaluate the types of traffic control stations suitable for construction on each target section, taking into account the construction cost while ensuring the accuracy of the monitoring data.

[0076] Specifically, for the traffic data monitored by other traffic monitoring facilities, the following conversion scheme is proposed:

[0077] (1) Regarding road traffic volume and road speed: The vehicle speed collected by multi-source data exchange stations such as non-site enforcement stations, bridge axle load detection, and video structuring can obtain the location speed in real time, which can be directly used as the vehicle speed indicator when forming the traffic volume indicator; the original single-vehicle data of the highway section is directly aggregated through non-site enforcement stations, bridge axle load detection, video structured extraction, etc., and the time granularity can be 5 minutes / hour for statistics.

[0078] (2) Regarding road vehicle types

[0079] When converting the traffic volume indicators by vehicle type, since the off-site enforcement station, bridge axle load detection, and video structured extraction cannot distinguish vehicles according to the inter-modulation vehicle type, conversion processing is required. Among them, the off-site enforcement station and bridge axle load detection can distinguish vehicles according to the number of axles. Table 1 shows the correspondence between the inter-modulation vehicle type and the axle load vehicle type.

[0080]

[0081] Table 1

[0082] It can be seen that there are three ways to determine the split coefficient for the cross-modulation model and axle load type:

[0083] 1) Proportional splitting method: Determine the proportional relationship of each vehicle type based on the historical data of the route or administrative division where the station is located, and then determine the splitting coefficient.

[0084] 2) Manual sampling method: Determine the splitting coefficient of the location of the multi-source data exchange station through manual investigation.

[0085] Through manual sampling survey, representative traffic monitoring facilities on the route were selected for manual observation, and the values ​​and proportions of medium and small trucks at that location were determined based on the manually collected data. At the same time, the data were compared with the data of 11, 12, 21, and 22 vehicle models collected by the traffic monitoring facilities at that location on the same day. Finally, the medium and small truck splitting coefficient at this location was determined as the splitting coefficient of the route.

[0086] 3) Image recognition method: Both the off-site enforcement station and video structured extraction record the image history information of each vehicle passing through the station. The traffic volume of each vehicle type is summarized through image recognition software to determine the number and proportion of each vehicle type as the splitting coefficient.

[0087] Based on this, the multi-source data intercommunication station set up on the target road section can convert the traffic data monitored by other traffic monitoring facilities into at least intercommunication data including the road section traffic volume, road section vehicle speed and road section vehicle type.

[0088] For example, when an automated traffic control station needs to be established on a target road section, the factors that should be considered include at least:

[0089] ① The purchase cost of the intermodulation equipment itself: The purchase cost of different intermodulation equipment is different, ranging from tens of thousands to hundreds of thousands. For example, the purchase cost of laser equipment is about three times that of toroidal coil equipment.

[0090] ② Installation, commissioning and daily maintenance costs of the modulation equipment: mainly including the installation costs of resetting the road surface, laying lines, erecting poles, gantries and other facilities and equipment, as well as the power supply and data network transmission costs, as well as the maintenance and verification costs after the operation;

[0091] ③ Configuration costs of other supporting facilities: In addition to the equipment itself, some modulation stations also require a series of software and hardware support. This cost should also be considered when selecting the type of modulation equipment to be deployed;

[0092] ④ The service life of the intermodulation equipment: The service life of the intermodulation equipment is related not only to the properties of the equipment itself, but also to the road conditions, environmental conditions and the management of overweight vehicles. Therefore, the service life of the same intermodulation equipment on different sections of road is different;

[0093] ⑤ External environment: Since the detection coverage area of ​​different intermodulation equipment is limited, the requirements for intermodulation equipment are different for different road grades and numbers of lanes. At the same time, different environments, such as high altitude, foggy and windy areas, require different intermodulation equipment. When deploying intermodulation equipment, the type and quantity of intermodulation equipment to be deployed should be determined based on the requirements of the external environment.

[0094] Based on this, appropriate intermodulation equipment can be configured for the newly built automated intermodulation station according to the above factors, taking into account both the deployment cost and the intermodulation data collection effect.

[0095] Figure 3 A schematic diagram of constructing an intermodulation acquisition network according to an embodiment of the present application is shown.

[0096] like Figure 3 As shown, first, according to the collection situation of each traffic control station in the existing traffic control collection network, each road section in the target area is divided into observation sections and non-observation sections, and then in the non-observation sections, the optimal solution that takes into account the layout cost and the coverage of important sections is calculated based on the mathematical model to select the target sections to add traffic control stations, and when adding traffic control stations, the types of additional traffic control stations are determined according to the actual situation. Among them, multi-source data traffic control stations are added to the target sections where the traffic data monitored by other traffic monitoring facilities (such as non-site law enforcement stations, bridge axle load detection, video structuring and other multi-source data traffic control stations) can meet the needs of the traffic control collection network, and automated traffic control stations are established for other target sections, thereby realizing full coverage collection of the road network.

[0097] The above describes the specific settings and implementation methods of the embodiments of the present application from different perspectives. Using the method provided in the above embodiments, the data collection effect of the existing intermodulation collection network can be evaluated, and the intermodulation stations can be selected to be added to some sections of the road by taking into account the layout cost of the intermodulation stations and the coverage requirements of important sections through the data model, and the types of intermodulation stations can be determined in a targeted manner according to the road section conditions, thereby overcoming the data collection capacity limitations of the original intermodulation collection network caused by factors such as changes in the road network structure, and meeting the needs of intermodulation data collection and traffic dispatching.
