Abstract
Description
Technical Field
[0001] This application relates to the field of highway management, specifically to a highway management method and platform based on road network space, electronic equipment, and computer-readable storage medium. Background Technology
[0002] In the field of highway transportation infrastructure construction and operation management, the accurate acquisition and correlation of location information is the core foundation for achieving efficient management, fault diagnosis, emergency response, and maintenance decision-making. With the continuous expansion of the highway network, a complex network system covering urban and rural areas and connecting regions has been formed. Against this backdrop, how to quickly and accurately locate any position within the road network and correlate it with the core indicator of highway management—the mileage marker—has become a critical issue that urgently needs to be addressed within the industry.
[0003] As a core location marker in highway construction and management, station numbers are typically set at certain intervals along the highway centerline, based on a specific starting point. They serve as crucial references for maintenance operations, accident handling, facility inspections, and other management activities. Traditional methods of highway location and station number acquisition primarily rely on manual inspections or pre-installed markers. Workers must carry paper maps or specialized equipment along the highway, comparing the site terrain with the map information to determine the target station number. This method is not only inefficient but also susceptible to environmental factors such as weather and terrain. In complex road networks or remote sections, positioning errors can often reach tens or even hundreds of meters, making it difficult to meet the needs of refined management.
[0004] With the development of Geographic Information System (GIS) and Global Positioning System (GPS) technologies, digital positioning methods have been gradually introduced into the field of highway management. Early digital solutions mostly used simple coordinate mapping methods, which involved overlaying GPS-acquired latitude and longitude coordinates onto the highway network layer. However, this method could only roughly mark the target location on the map and could not directly associate it with the corresponding station information. Some improved solutions attempted to solve this problem by establishing a linear mapping relationship between latitude and longitude coordinates and station numbers, but they ignored the complexity of the actual road alignment—highway routes are not completely straight but contain curves, slopes, and other complex alignments. Simple linear interpolation calculations would lead to a significant increase in station deviation, especially on road sections with small curve radii, where the positioning error could even exceed 100 meters, seriously affecting the accuracy of management decisions.
[0005] Furthermore, with the deepening advancement of the intelligent transportation concept, highway management systems are developing towards real-time and intelligent capabilities, placing higher demands on the speed and accuracy of location information acquisition. Existing technical solutions are prone to road segment identification errors in areas with multiple road intersections and complex road network topologies, leading to deviations in station determination. Simultaneously, some solutions fail to update and maintain road network data in a timely manner. When highway reconstruction or network adjustments occur, the mapping relationship between coordinates and station numbers cannot be updated synchronously, further exacerbating positioning inaccuracies. Therefore, developing a technical solution that can quickly and accurately convert the latitude and longitude coordinates of a target location into corresponding station numbers based on road network spatial characteristics, ensuring that every point in the road network has a unique spatial identifier and intuitively displaying relevant information, has become a key breakthrough for improving the efficiency and precision of highway management.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] This application provides a highway management method and platform based on road network space, an electronic device, and a computer-readable storage medium, which are described below.
[0025] Please refer to Figure 1 The highway management method based on road network space provided in this application includes: Step S101: Obtain the target location in the road network space and determine the target latitude and longitude coordinates corresponding to the target location.
[0026] In this step, the target location is the location where the user needs to view the latitude and longitude coordinates and station number. Specifically, in practical applications, a road map can be displayed on the display device using a map engine. The user triggers a mouse event on the displayed road map through interaction methods such as clicking or hovering the mouse for a long time. The mouse position coordinates corresponding to the mouse event are obtained, and then the map engine's screen coordinate to latitude and longitude coordinate conversion interface is called to convert the mouse position coordinates into the target latitude and longitude coordinates.
[0027] The map engine has integrated an SDK and completed initial configuration. When a mouse event is triggered, the screen coordinates (usually x and y pixel values, with the top-left corner of the container as the origin) of the mouse relative to the map container are obtained through the event object corresponding to the mouse position coordinates (such as JavaScript's MouseEvent). The map engine's screen coordinate to latitude / longitude coordinate conversion interface is called, passing in the screen coordinates x and y and current map state parameters (such as map zoom level, current view center point latitude and longitude, container size, etc.). Internally, the interface uses the map engine's projection algorithm (such as Mercator projection) to convert the screen pixel coordinates inversely to latitude / longitude coordinates in the geographic coordinate system. During the conversion, the coordinate mapping relationship is corrected based on the current map zoom level to eliminate the impact of view zoom on coordinate accuracy. After the interface call is completed, the conversion result is received through a callback function or return value. The result is then validated (e.g., latitude / longitude range validity check). Once the validation is successful, the target latitude / longitude coordinates corresponding to the target location are obtained.
[0028] Step S102: Based on the target latitude and longitude coordinates, obtain the target road segment to which the target location belongs, and obtain the latitude and longitude coordinates and station numbers of the endpoints of the target road segment.
[0029] In the road network space, all highways are pre-divided into multiple road segments. For each road segment, a corresponding latitude and longitude region is set according to its location, and a corresponding latitude and longitude boundary is set for each latitude and longitude region. In this step, the target latitude and longitude coordinates are compared with the preset latitude and longitude boundaries to determine the latitude and longitude region where the target latitude and longitude coordinates are located. Further, based on the latitude and longitude region where the target latitude and longitude coordinates are located, the target road segment to which the target location belongs can be determined. Further, based on pre-stored data, the pre-stored endpoint latitude and longitude coordinates and endpoint station numbers corresponding to the road segment endpoints are obtained. Here, the target road segment is a line segment structure, so it includes two endpoints. In this embodiment, either endpoint can be selected as the road segment endpoint, and its corresponding endpoint latitude and longitude coordinates and endpoint station numbers can be obtained. In some other embodiments of this application, for example, the endpoint with a smaller distance from the target location can be selected as the road segment endpoint, or the endpoint with a smaller / larger station number can be selected as the road segment endpoint, etc.
[0030] Step S103: Calculate the target distance between the target location and the end point of the road segment based on the target latitude and longitude coordinates and the endpoint latitude and longitude coordinates.
[0031] In the road network space, vector data, stationing data, and latitude and longitude coordinate system data of the highway network are collected in advance. All highways are divided into multiple road segments, and road segments are associated with corresponding stationing information through node_id to form a structured road network database. At the same time, the integrated road network vector data is converted into GeoJSON format, containing geometric information, attribute information, and other data of each road segment element, and loaded into the layer of the front-end map engine.
[0032] In this step, after determining the target's latitude and longitude coordinates, the `lineSliceAlong` method of `Turf.js` is called to obtain all vector road segment data between the target location and the road segment endpoints from the road network space, based on the target's latitude and longitude coordinates and the endpoint's latitude and longitude coordinates. The `length` method of `Turf.js` is then called to convert each vector road segment data into a `LineString` object. The length of each vector road segment is calculated using the Haversine formula or the Vincenty formula. Finally, the target distance is obtained by summing all the vector road segment lengths.
[0033] Specifically, the `lineSliceAlong` function slices a new road segment along the complete road segment (LineString object) provided by the road network space, starting from the segment endpoint and extending to the target location. It then creates a new GeoJSON object based on this new segment (containing all vector road segment data between the target location and the segment endpoint). This new GeoJSON object only contains the geographic data from the original segment endpoint to the mouse hover point. Further, the `length` function first ensures that the new GeoJSON object is of type LineString or MultiLineString. If not, it converts it to a LineString object. Then, the `length` function iterates through each point in this LineString, calculating the distance between every two adjacent points. Since the Earth is a sphere, this embodiment uses the Haversine formula or Vincenty formula (distance = 2 × R × arcsin(√[sin...)). 2 (Δφ / 2)+cosφ1·cosφ2·sin 2 (Δλ / 2)]), R: Earth radius, Δφ: latitude difference, Δλ: longitude difference) calculate the length of each vector road segment. Finally, add up the calculated distances between all adjacent points to get the total length of the entire intercepted line segment, which is the target distance between the target location and the end point of the road segment.
[0034] Step S104: Calculate the target station number corresponding to the target location based on the target distance and the endpoint station number.
[0035] In the road network space, for any road segment, its station number gradually increases / decreases from one end to the other. Based on this, this step first obtains the station number increment / decrement rules from the road segment endpoint to the target location, including the gradual increase / decrease, the length of the unit distance, and the numerical increase / decrease per unit distance. Then, based on the increment / decrement rules and the target distance, the increment / decrement amount of the target station number is determined. Finally, the target station number is calculated based on the endpoint station number and the increment / decrement amount. For example, for a certain road segment, the station numbers of endpoints S and E are S=K0+000 and E=K50+000 respectively. Then the target station number corresponding to the target location is S+D / K or ED / K (D is the target distance, K is the unit length). For example, if D is the target distance from the target location to endpoint S, then the target station number is S+D / K. When D=1250 meters and K=1000 meters, the target station number is K0+000+1.250=K1+250. Another example is that if D is the target distance from the target location to endpoint E, then the target station number is SD / K, and the station number is K50+000-1.250=K48+750.
[0036] Step S105: Display the target road segment, target latitude and longitude coordinates, and target station number.
[0037] Compared with related technologies, the highway management method based on road network space provided in this application, after determining the target location in the road network space, further determines the target latitude and longitude coordinates corresponding to the target location. Then, based on the target latitude and longitude coordinates and the latitude and longitude boundaries of the areas where each road segment is located stored in the road network space, the target road segment to which the target location belongs is determined. Subsequently, the latitude and longitude coordinates and station numbers of the endpoints of the target road segment are obtained. By calculating the target distance between the target location and the endpoint of the road segment based on the target latitude and longitude coordinates and the endpoint latitude and longitude coordinates, the target distance is calculated based on the target distance and the endpoint station number. Thus, the target road segment, target latitude and longitude coordinates, and target station number corresponding to the target location can be accurately determined and displayed. This achieves the technical effect of quickly and accurately determining the latitude and longitude coordinates and corresponding station numbers of the target location, thereby improving the efficiency and refinement of highway management.
[0038] Please refer to Figure 2 Another embodiment of this application also provides a highway management method based on road network space, including: Step S201: Obtain the target location in the road network space and determine the target latitude and longitude coordinates corresponding to the target location.
[0039] Step S202: Based on the target latitude and longitude coordinates, obtain the target road segment to which the target location belongs, and obtain the latitude and longitude coordinates and station numbers of the endpoints of the target road segment.
[0040] Step S203: Calculate the target distance between the target location and the end point of the road segment based on the target latitude and longitude coordinates and the endpoint latitude and longitude coordinates.
[0041] Step S204: Calculate the target station number corresponding to the target location based on the target distance and the endpoint station number.
[0042] It is understood that steps S201 to S204 in this embodiment are largely the same as steps S101 to S104 in the previous embodiment. For details, please refer to the specific description in the previous embodiment.
[0043] Step S205: Determine whether there is a first camera that corresponds to the target station number. If yes, proceed to step S206; otherwise, proceed to step S207.
[0044] Specifically, multiple correspondences between station numbers and cameras are pre-stored in the road network space. In this step, a search is performed in the pre-stored correspondences to determine whether a first camera corresponding to the target station number exists. If it exists, step S206 is executed; otherwise, step S207 is executed.
[0045] Step S206: Display the target road segment, target latitude and longitude coordinates, target station number, and the monitoring screen of the first camera.
[0046] Step S207: Obtain the target shooting area based on the target latitude and longitude coordinates, and determine whether there is a second camera in the target monitoring area. If so, proceed to step S208.
[0047] Specifically, multiple cameras and their corresponding latitude and longitude coordinates are pre-stored in the road network space. In this step, a circle is drawn with the target latitude and longitude coordinates as the center and a preset radius to obtain the target monitoring area (or other methods can be used, such as extending a preset distance to both sides of the road based on the set target location). Based on the pre-stored camera latitude and longitude coordinates, it is determined whether there is a second camera in the target monitoring area. If there is a second camera, step S208 is executed.
[0048] Furthermore, if there are multiple second cameras in the target shooting area, a specific second camera can be selected to execute step S208 based on parameters such as the distance from the target location and the camera resolution.
[0049] Step S208: Display the target road segment, target latitude and longitude coordinates, target station number, and the monitoring screen of the second camera.
[0050] Compared with related technologies, the road management method based on road network space provided in this embodiment, on the basis of the aforementioned embodiments, additionally obtains the corresponding first or second camera according to the target station number and target latitude and longitude coordinates, and displays the monitoring images of the first or second camera, which allows command personnel to have a more comprehensive and efficient grasp of the road status at the target location, providing richer information support for maintenance management, emergency response and other work.
[0051] Please refer to Figure 3 Another embodiment of this application also provides a highway management method based on road network space, including: Step S301: Obtain the target location in the road network space and determine the target latitude and longitude coordinates corresponding to the target location.
[0052] Step S302: Based on the target latitude and longitude coordinates, obtain the target road segment to which the target location belongs, and obtain the latitude and longitude coordinates and station numbers of the endpoints of the target road segment.
[0053] Step S303: Calculate the target distance between the target location and the end point of the road segment based on the target latitude and longitude coordinates and the endpoint latitude and longitude coordinates.
[0054] Step S304: Calculate the target station number corresponding to the target location based on the target distance and the endpoint station number.
[0055] It is understood that steps S301 to S304 in this embodiment are largely the same as steps S101 to S104 in the previous embodiment. For details, please refer to the specific description in the previous embodiment.
[0056] Step S305: Determine whether there are road supporting facilities at the target location based on the target's latitude and longitude coordinates. If there are road supporting facilities at the target location, display the road supporting facilities.
[0057] Specifically, highway supporting facilities include various highway-related information parameters such as toll stations, tunnels, service areas, bridges, and slopes. The latitude and longitude coordinates of these supporting facilities are pre-stored in the road network space. In this step, the target's latitude and longitude coordinates are compared with the pre-stored coordinates of the supporting facilities to determine if highway supporting facilities exist at the target location. If they do exist, the relevant information is displayed.
[0058] Furthermore, within the road network space, highway infrastructure data is stored in a JSON file named "zdss.json," where the `type` field distinguishes infrastructure types. When the front-end initializes the current page, it retrieves the "zdss.json" data using `axios.get` and stores it in a variable. When displaying information related to highway infrastructure, the data is reorganized based on different infrastructure types and subcategories within the pre-stored data, and different icons are set. For example, tunnels are distinguished as key tunnels and general tunnels, with key tunnels further differentiated into extra-long and extra-long tunnels. Toll stations are selected by default and displayed hierarchically.
[0059] Furthermore, in this embodiment, it is also possible to acquire pre-stored surrounding cameras associated with highway supporting facilities and display the monitoring images of the surrounding cameras.
[0060] Step S306: Display the target road segment, target latitude and longitude coordinates, and target station number.
[0061] Compared with related technologies, the road management method based on road network space provided in this embodiment, on the basis of the aforementioned embodiments, additionally determines whether there are road supporting facilities at the target location based on the target's latitude and longitude coordinates, and displays relevant data of road supporting facilities and monitoring images of associated surrounding cameras. This allows command personnel to have a more comprehensive and efficient grasp of the road supporting facilities at the target location, providing richer information support for maintenance management, emergency response and other work.
