[0052] In order to make the embodiments of the present application more clear, the following briefly introduces concepts and some contents related to the embodiments of the present application.

[0053] 1. Road network: refers to a networked road system composed of various roads or road sections in a certain area.

[0054] 2. Road operation status: referred to as road conditions, refers to the congestion status of roads or road sections. Road conditions can include clear, relatively clear, slightly congested, moderately congested, and severely congested.

[0055] 3. Road condition screen: It refers to the display screen placed on the road to display the road conditions ahead.

[0056] The above is a brief introduction to some concepts involved in this application.

[0057] like figure 2 As shown, it is a flowchart of a method for generating a road operating condition map provided by the present application. The method includes:

[0058] S201. The computer device receives a first operation of a user on a map interface.

[0059] The map interface refers to the interface including the road network. like image 3 As shown, it is the interface of the road network including a plurality of roads in area A.

[0060] Optionally, the above-mentioned map interface includes identifiers of multiple road segments, and the identifiers of the multiple road segments are the names or unique identifiers (Identity document, ID) of the road segments. For example, the road segment name "Heping Road", or the unique identifier "244927431" represents the road segment.

[0061] Specifically, the first operation is that the user clicks one or more positions on the map interface, or the first operation is to frame one or more areas of the map interface.

[0062] S202. The computer device determines the target road segment in response to the first operation.

[0063] In a first possible implementation manner, the first operation is that the user clicks one or more positions on the map interface, and the computer device selects the first road segment in response to the clicked operation, and uses the first road segment as the target road segment. like Figure 4 In the map interface, the user determines the target road segments AB, CD and EF that need to be displayed on the road condition screen, and selects the road segments from point A to point B, point C to point D, and point E to point F in the map, Figure 4 shown in bold line segments.

[0064] It can be understood that, in this implementation manner, the user selects the target road section by clicking on his/her own, and the selection method includes various methods. For example, the user selects the target road segment AB by clicking and dragging point A to point B in the map interface. For another example, the user clicks point A and then clicks point B in the map interface, and the computer device generates the target road segment AB from A to B according to the order of the user's clicks.

[0065] In the second possible implementation manner, the user performs a frame selection on the map interface, and the first operation is used to indicate the target area. The computer device selects the target area in response to the box selection operation, and the road section included in the target area is used as the target road section. like Figure 5 As shown, the user selects a target area in a box, the target area includes road segments A'B', road segments C'D' and road segments E'F', and the start and end positions of the multiple road segments are selected in the target area. On the edge, the plurality of road segments are used as target road segments.

[0066] In a third possible implementation manner, the user clicks on the map interface, and the computer device automatically selects the first road segment in response to the clicking operation, and uses the first road segment as the target road segment. The position selected by the user on the map interface has a corresponding relationship with the first road segment. The corresponding relationship is preset in the map interface, for example, road segments are divided according to overlapping positions between roads. The overlapping position of each road segment with other road segments is located at the start or end position of the road segment, and does not overlap with other road segments in the middle of each road segment. like Image 6 As shown, the user clicks point A to select road segment aM, clicks point B to select road segment Mb, clicks point C to select road segment cN, clicks point D to select road segment Nd, clicks point E to select road segment eM, clicks point F to select road segment Nf, clicks point G to select segment Section MN. Wherein, the area where the overlapping position is located includes any one of the multiple overlapping road segments. For example, in Image 6 , multiple road segments overlap at points M and N, and when the computer device clicks points M and N, the road segment MN is selected accordingly. The computer device takes the selected road segment as the target road segment.

[0067] For another example, the middle of a road segment overlaps with other road segments. For example, in Image 6 , whether the user clicks point E, point G or point F, it corresponds to the road segment ef. In this application, there is no limitation on the correspondence between the user-clicked position and the road segment.

[0068] Optionally, before the above step S201, the method further includes steps S200a and S200b.

[0069] S200a. The computer device receives a second operation from the user, where the second operation is used to designate a road condition screen that needs to display a road operating condition map.

[0070] Wherein, the user performs the second operation on the road condition screen selection interface. like Figure 7a As shown, it is a road condition screen selection interface, which includes information and operation options of multiple road condition screens. Specifically, the information of the road condition screen includes the serial number in the plurality of road condition screens, the road condition screen name as the unique identifier of the road condition screen, the area to which the road condition screen belongs in the map, and the road condition configuration representing the configuration state of the road condition screen. The operation option is used for the user to perform a second operation to start the configuration of the road condition screen. E.g, Figure 7a The middle is located in multiple road condition screens, the serial number is 1, the road condition screen name is 244927431, its area is area A, and the road condition configuration is not configured.

[0071] It should be noted that the information on the road condition screen may also include more or less information, for example, may also include an organization to which the road condition screen belongs, where the organization to which the road condition screen belongs refers to a department that manages the road condition screen. Alternatively, the information of the road condition screen may be represented by other means. For example, the name of the road condition screen may also be represented by a user-defined character, which is not limited in this application.

[0072] It should be noted that this application does not limit the manner of the second operation, for example, in Figure 7a , the user clicks the operation option in the road condition screen selection interface to indicate the corresponding road condition screen.

[0073]Optionally, the road condition screen selection interface may further include a reference map interface where the road condition screen is located, as a reference for the user to perform the second operation. Specifically, the user performs a third operation on the road condition screen selection interface, and the computer device displays a reference map interface in response to the third operation. Wherein, the present application does not limit the manner of the third operation, for example, in Figure 7a , the user can click the name of the road condition screen or other information on the road condition screen to display the reference map interface of the corresponding road condition screen. Wherein, the reference map interface is used to indicate the location of the road condition screen in the road network of the area to which it belongs. Exemplarily, in response to the user targeting Figure 7a The name of the traffic screen in the click operation is 244927431, and the display is as follows Figure 7b The reference map interface shown. Wherein, the reference map interface may further include the information of the road condition screen and an editing option, and the editing option is used for the user to perform a second operation to start the configuration of the road condition screen.

[0074] S200b. In response to the second operation, the computer device displays a map interface including the location of the road condition screen and the road network associated with the road section screen.

[0075] The road network associated with the road condition screen includes roads near the road condition screen and roads displayed in the road condition screen.

[0076] Optionally, based on the location of the road condition screen, a sign corresponding to the location of the road condition screen is displayed on the map interface.

[0077] Exemplarily, in response to the user targeting Figure 7a Click the operation option corresponding to the traffic screen 244927431, or, in response to the user's Figure 7b Click the Edit option to display something like image 3 The shown map interface includes the map interface of the road network associated with the road condition screen and the identification of the road condition screen.

[0078] S203, the computer device displays the drawn road section corresponding to the target road section on the drawing interface.

[0079] Specifically, the computer device acquires the location information of the target road segment in the map, and based on the location information, displays the drawn road segment corresponding to the target road segment on the drawing interface. Exemplarily, the location information is a set of multiple points forming the target road segment in the map, and the location information includes coordinate information of the multiple points. For example, the coordinate information of multiple points is latitude and longitude information, and the computer equipment converts the latitude and longitude information into plane coordinates.

[0080] Optionally, the drawn road segment exactly matches the target road segment. Specifically, when the location information includes the overall location information of the target road segment, the overall location information of the target road segment is mapped to the drawing interface to obtain the drawn road segment. Wherein, the overall position information of the target road segment includes at least three plane coordinates that constitute the target road segment. For example, the computer equipment maps all the plane coordinates constituting the target road segment in proportion, and the mapped drawn road segment has the same shape as the target road segment. like Figure 8a shown, for Figure 4 The selected target road segments AB, CD and EF are the drawn road segments obtained by mapping. The drawn road section obtained in this way is helpful to restore the shape of the road in the road condition screen, which is convenient to improve the look and feel of the road condition screen.

[0081] Optionally, the drawing interface is used for the user to adjust the display characteristics of the drawn road segment in the interface. Wherein, the display features include at least one of the following: display length, display width, display color, display direction, display curvature and text features. The display length refers to the length of the drawn road segment. Display width refers to the width of the drawn road segment. Display color refers to the color in which the road segment is drawn, wherein different colors can be used to indicate different road conditions. The displayed direction refers to the indicated direction of the drawn road section. It can be understood that the indicated direction of the target road section in the map is different from the direction in the road condition screen observed by the driver. Therefore, the indicated direction of the drawn target road section can be adjusted by adjusting the indicated direction. , adapted to the driver's viewing direction.

[0082] Display curvature refers to the curvature of drawn road segments, including straight lines and curves. Specifically, the curvature of the target road section in the map may be bent to varying degrees. It can be understood that the road condition screen is usually used to indicate the road conditions of one or more road sections ahead to the driver, in order to avoid the bending of some road sections. As a result, the display of road sections is not clear, which interferes with the display of road condition information, and the specific shape of one or more road sections can be adaptively ignored.

[0083] Specifically, when the displayed curvature is a curve, it means that the drawn road segment completely matches the target road segment. When the displayed curvature is a straight line, it means that the drawn road segment does not exactly match the target road segment. When the location information includes the location information of the starting point and the location information of the end point of the target road segment, the location information of the starting point and the location information of the end point are mapped on the drawing interface, and the line connecting the location of the starting point and the location of the end point is used as the drawing road segment. like Figure 8b shown, for Figure 4 The selected target road segments AB, CD, and EF are the drawn road segments obtained by connecting the position information of the starting point of the target road segment and the position information of the end point. Wherein, the computer device can also be automatically adjusted according to the deflection angle between the overall position information of the target road segment AB. For example, in Figure 4 When it is judged that the deflection angle between the plane coordinates constituting the target road segment AB is smaller than the first threshold, the line connecting point A and point B of the target road segment AB is used as the drawn road segment when drawing the road segment. The first threshold can be set by the user, which is not limited in this application.

[0084] The text feature is used to represent at least one of the name of the target road segment and the location information of the target road segment. like Figure 8c shown in Figure 8a On the basis of the target road section EF, the name "Peace Road" is added. It can be understood that the text feature may also include the display direction in the drawing interface. For example, vertical text or horizontal text.

[0085] S204, the computer device acquires the road condition information of the target road segment.

[0086] Optionally, the computer device acquires road condition information of the target road segment based on the location information of the target road segment. Exemplarily, the computer device acquires the identifier of the target road segment based on the location information of the target road segment, and acquires the road condition information of the target road segment according to the identifier of the target road segment.

[0087] It can be understood that the current road condition information has a corresponding relationship with the road segment. Among them, there are many kinds of information representing road conditions. For example, the average driving speed of vehicles in a preset time period in the road section is collected. When the average driving speed is greater than the first threshold, the road section is considered to be unobstructed. When the average driving speed is greater than the second threshold, When it is less than the first threshold, the road section is considered to be slightly congested, and when the average driving speed is less than the second threshold, it is considered that the road section is seriously congested. This application does not limit this.

[0088] Optionally, the computer device receives the correspondence between the identifier of the target road segment and the road condition information. As shown in Table 1 below, it is an example of the correspondence between the identifier of the target road segment and the road condition information.

[0089] Table 1

[0090] road section logo road condition AM 000 00 MB 001 01 EN 010 01 ND 011 11 EM 100 10 MN 101 11 NF 110 10

[0091] Specifically, the flag is used to indicate a road segment, and the road conditions of different road segments have a corresponding relationship with the flag respectively. Exemplarily, four road conditions are shown in Table 1 above, "00" represents a clear state, "01" represents a relatively clear state, "10" represents a slightly congested state, and "11" represents a severely congested state. Then the identification is "000" and the road condition is "00", indicating that the road condition of the road segment AM is in a smooth state.

[0092] It should be noted that the corresponding relationship between the target road segment and the road condition is the same as the corresponding relationship between the road segment to which the target road segment belongs and the road condition. Specifically, as Image 6 As shown, on the map, the road segment AM in the target road segment AB is located in the road segment aM, and the road segment MB is located in the road segment Mb, and the road segment aM and the road segment Mb are the road segments with signs in the map, so, according to the location information of the target road segment AB to determine The identification of the road section includes the identification of the road section aM and the identification of the road section Mb. According to the predefined correspondence between the identifier of the road segment and the road condition, the road condition corresponding to the identifier of the road segment aM (that is, the road condition of the road segment aM) and the road condition corresponding to the identifier of the road segment Mb (that is, the road condition of the road segment Mb) are determined.

[0093] S205. The computer device generates a road operating condition map of the target road segment; wherein the road operating condition map includes the drawn road segment and the corresponding relationship between the road condition information of the target road segment and the drawn road segment.

[0094] Optionally, the corresponding relationship between the road condition information of the target road segment and the drawn road segment includes a first corresponding relationship, where the first corresponding relationship refers to a color representing the road condition of the drawn road segment. For example, in combination with the four road conditions in Table 1 above, they correspond to different colors. Red indicates severe congestion, yellow indicates slight congestion, blue indicates relatively smooth flow, and green indicates smooth flow. The road health map includes painted road segments in different colors. like Figure 9 As shown in the figure, the left oblique line represents the smooth state, the right oblique line represents the relatively smooth state, the grid pattern represents the relatively smooth state, and the black represents the severe congestion state.

[0095] Optionally, the corresponding relationship between the road condition information of the target road segment and the drawn road segment includes a second corresponding relationship, where the second corresponding relationship refers to the road condition of the drawn road segment represented by text. For example, in combination with the four road conditions in Table 1 above, it represents unblocked, relatively unblocked, slightly congested, and severely congested, respectively. It is indicated by text next to the corresponding drawn road segment, such as Figure 10 shown.

[0096] It should be noted that the correspondence between the road condition information of the target road segment and the drawn road segment may also include other methods, which are not limited in this application.

[0097] The computer device generates a road operating condition map based on the above-mentioned location information, road condition information and display characteristics.

[0098] After the above step S205, the computer device sends the information of the road operating condition map to the road condition screen, and the road operating condition graph is displayed on the road condition screen. The information of the road operation status map refers to any kind of information that can display an image, which is not limited in this application.
