[0042] To make the above-mentioned objectives, features and advantages of this disclosure more apparent and understandable, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0043] To facilitate understanding of the technical implementation of this disclosure, the technical terms involved in this disclosure will be explained below.

[0044] Link: A road segment, a directed unit divided according to the actual road. Each link corresponds to an actual road and has a unique identifier (ID).

[0045] A link pair is a pair of road segments. If two links are geographically connected through an intersection, they can be considered as a link pair. In this disclosure, it can be understood as a link pair consisting of a link before a traffic light and a link after the traffic light.

[0046] Traffic light timing: In this disclosure, it refers to the timing information of traffic lights.

[0047] Traffic light timing information can include signal cycle, green light time, yellow light time, and red light time. The signal cycle refers to the complete cycle time of a traffic light, including the green light time, yellow light time, and red light time. The signal cycle is generally between 20 and 180 seconds, and is set according to traffic demand and traffic volume.

[0048] The green light duration is one of the main parameters of traffic lights. When the red light turns green, vehicles can proceed until the green light ends or all vehicles have passed. The green light duration is generally set according to traffic demand and traffic flow.

[0049] The yellow light duration is the transition time between the red and green lights, intended to prompt vehicles to slow down and prepare to stop or continue driving. The yellow light duration is generally 1-3 seconds.

[0050] Red light time refers to the time between the end of the green light and the start of the next green light, during which vehicles are not allowed to pass. Red light time is generally set based on traffic demand and traffic flow.

[0051] Traffic light controlled scenario: This means that the link pair at the traffic light intersection is controlled by the traffic lights and needs to follow the traffic light instructions to pass through the current intersection.

[0052] Traffic light obstruction scenarios: These are situations where a link pair at a traffic light intersection is not controlled by the traffic light and can proceed at any time, but is blocked because it cannot pass directly ahead. For example, if a right turn and a straight-ahead vehicle are in the same lane, but the right turn is not controlled by the traffic light while the straight-ahead vehicle is, then a right-turning vehicle behind in that lane will be blocked by a straight-ahead vehicle in front. Similarly, if a left turn and a U-turn are in the same lane, but the U-turn is not controlled by the traffic light while the left turn is, then a U-turning vehicle behind in that lane will be blocked by a left-turning vehicle in front.

[0053] For example, Figure 1 is a schematic diagram of a road condition provided by an embodiment of this disclosure. In the application scenario shown in Figure 1, link1 and link3 are geographically connected, forming a link pair. Vehicles passing through this link pair are not subject to traffic light control. Link1 and link2 are geographically connected, forming a link pair. Vehicles passing through this link pair are subject to traffic light control. Link1 is the link before the traffic light, and link2 is the link after the traffic light. In lane 2 of link1, vehicle 1 is a straight-going vehicle, and vehicle 2 is a right-turning vehicle. If the light is red, vehicle 1 is controlled to go straight and stops, while vehicle 2 is not affected by the traffic light and can continue to go, but cannot turn right because vehicle 1 is blocking it. How to provide effective information to the blocked vehicles so that users can know when they can pass is an urgent technical problem to be solved.

[0054] Based on this, this disclosure provides a solution that allows users blocked in front of a traffic light to clearly see the countdown information of the traffic light corresponding to the controlled vehicle blocking their path.

[0055] To facilitate understanding of this disclosure, the navigation method provided herein will be described below with reference to the accompanying drawings.

[0056] Referring to Figure 2, which is an interactive diagram of a traffic information processing method provided in an embodiment of this disclosure, as shown in Figure 2, the method includes:

[0057] S201: The client sends a data request to the server. The data request is at least used to request the target vehicle's passage data in the obstructed scenario.

[0058] In this embodiment, a client with navigation functionality can periodically send data requests to the server to request traffic data for the target vehicle in obstructed scenarios. This traffic data includes traffic light information (such as traffic light timing information). For example, during navigation, the vehicle sends data requests to the server every 5 minutes. Each request is used to request traffic data at a preset distance / preset intersection along the navigation route. If two adjacent traffic data returned by the server overlap, the later data overwrites the earlier data.

[0059] Understandably, clients can also send data requests to the server under certain conditions, such as at each light along the route, or at a predetermined distance from an intersection where there is obstruction.

[0060] In this context, an obstruction scenario refers to a situation where a vehicle traveling along the navigation route through the target lane is not controlled by traffic lights, but other vehicles traveling along the same route in the target lane are controlled by traffic lights. This means the target lane includes at least one direction controlled by traffic lights. When a vehicle is traveling in the target lane, it may be blocked by a vehicle in front (whose direction is controlled by traffic lights). For example, in Figure 1, lane 2 of link 1 allows both straight and right turns. The straight direction is controlled by traffic lights, while the right turn is not. Lane 2 is the target lane. If vehicle 2 attempts to turn right in lane 2, but vehicle 1 is traveling straight, vehicle 2 may be blocked by vehicle 1.

[0061] S202: The server obtains the target passage data based on the data request.

[0062] S203: The server sends the target passage data to the client.

[0063] In this embodiment, the data request may include the location of the target vehicle. After receiving the data request, the server will obtain the traffic light traffic data at intersections within a preset distance or a preset number of intersections from the target vehicle's location as the target traffic data. For example, the server can be pre-configured to provide the client with traffic light traffic data for the direction of travel within 500 meters of the vehicle, or pre-configured to provide the client with traffic light traffic data for the three intersections ahead of the vehicle. In other words, regardless of whether it will obstruct the target vehicle, the server can send the traffic light traffic data that matches the pre-configured traffic data to the client.

[0064] In some scenarios, to avoid the server identifying traffic lights that are not the ones the target vehicle will pass through, the data request also includes a user identifier. The server uses this user identifier to determine the navigation route for the target vehicle. Each user identifier corresponds one-to-one with a navigation route. When obtaining target traffic data, the server uses the traffic data of traffic lights within a preset distance or a preset number of intersections on the navigation route as the target traffic data, and then sends this target traffic data to the client.

[0065] Furthermore, to reduce the bandwidth and client resource consumption of data transmission, the server can selectively send traffic light data that may obstruct the target vehicle. In this scenario, after determining the traffic light traffic data, the server then determines which traffic light might cause obstruction based on the navigation route, and sends the traffic light traffic data to that traffic light in order to send it to the client. For example, the server obtains the traffic data of three traffic lights on the navigation route based on the target vehicle's location. However, the first two traffic lights require the user to go straight and there is no obstruction, while the third traffic light requires a right turn and there is an obstruction. In this case, the traffic data corresponding to the third traffic light can be sent to the client as the target traffic data.

[0066] Specifically, the server determines the roads the target vehicle will travel on based on the navigation route. For any road traveled, it determines whether the target lane exists. If the target lane exists, it indicates that the target vehicle may be obstructed while traveling on that road.

[0067] For example, in the scenario shown in Figure 1, the driving route of vehicle 2 indicates that it will turn right at the intersection ahead of link 1. The right turn in lane 2 is not controlled by traffic lights, but it can also go straight in lane 2, which will be controlled by traffic lights. Therefore, it is determined that vehicle 2 may be obstructed when driving in link 1.

[0068] The road includes the target lane, which can include the following:

[0069] One scenario is where the number of lanes on the road remains unchanged and a target lane exists. Figures 3a-3b are schematic diagrams of an obstructed scenario provided by an embodiment of this disclosure. For example, as shown in Figure 3a, the right lane in Figure 3a includes straight-ahead and right-turn lanes. Straight-ahead traffic is controlled by traffic lights, while right-turn traffic is not controlled by traffic lights. Therefore, the right lane is an obstructed lane, i.e., the target lane.

[0070] Another scenario involves a change in the number of lanes on the road, with a target lane existing before or after the change. This change in lane number can include either an increase or a decrease in the number of lanes. For example, as shown in Figure 3b, the road changes from two lanes to three lanes. Before the change, the right lane allowed both straight and right turns. Vehicles traveling in the right lane before the lane number change might experience obstruction; the right lane would then be considered an obstructed lane.

[0071] It should be noted that not all two directions of travel in the target lane are marked with lane direction guide lines. For example, the rightmost straight lane may only have straight direction guide lines, but it can also be used for right turns. In this case, the rightmost straight lane can also be the target lane.

[0072] The target traffic data may also include obstruction categories, which indicate the traffic-controlled direction causing the obstruction of the target vehicle. In this scenario, the target traffic data includes the obstruction category and the corresponding traffic light information. For example, if a right turn is obstructed due to going straight, the target traffic data includes the traffic light information for the straight-ahead direction.

[0073] S204: The client responds to the target vehicle being blocked by displaying the target traffic light countdown information.

[0074] In this embodiment, after the client detects that the target vehicle is obstructed, it will display the target traffic light countdown information to the user, allowing the user to clearly understand the red light countdown information causing the obstruction. For example, the target traffic light countdown information can be displayed on the navigation page and / or announced via voice. The client can determine whether the target vehicle is obstructed based on its location and the navigation route. The client can obtain the target vehicle's location in real time using a Global Navigation Satellite System (GNSS), which may include the Global Positioning System (GPS), the BeiDou Navigation Satellite System, etc.

[0075] Determining whether the target vehicle is obstructed can be performed by either the client or the server.

[0076] 1. When executed by the client, it may include: determining whether the vehicle is in a blocked state based on the target vehicle's location and navigation route.

[0077] Specifically, the system determines the target vehicle's lane and speed based on its location; and determines whether the target vehicle is obstructed based on its lane location, speed, and navigation route. This can be implemented in the following ways:

[0078] One approach is to determine if the target vehicle is in an obstructed state if the lane it is currently traveling in is the target lane, the target vehicle's speed is less than a first preset speed threshold, and the navigation route indicates that the target vehicle is traveling in a direction not controlled by traffic lights. In other words, if the target vehicle is currently traveling in the target lane, its direction of travel is not controlled by traffic lights, and its speed is less than the first preset speed threshold, it indicates that the target vehicle will be blocked by a vehicle traveling in a direction controlled by traffic lights (due to a red light), thus determining that the target vehicle is in an obstructed state.

[0079] Another approach is to determine if the target vehicle is obstructed if it is currently in a lane other than the target lane, its speed is less than a second preset speed threshold, and the navigation route indicates that it is about to enter the target lane. In other words, if the target vehicle is not in the target lane but is traveling at a low speed and is about to enter the target lane based on the navigation route, it indicates that the target vehicle is about to be blocked by a vehicle in the target lane whose direction is controlled by the traffic light, thus determining that the target vehicle is obstructed.

[0080] The client can calculate vehicle speed based on GNSS data. Specifically, the client obtains the distance traveled over a period of time via GNSS, and then calculates the vehicle speed based on this distance and the statistical duration.

[0081] In determining vehicle speed, the target vehicle's position is based on two points in time (start and end). The distance traveled by the target vehicle is obtained from these two points, and the speed is then determined based on this distance and the corresponding travel time (the difference between the two points). In determining the target lane, the target vehicle's position is based on a specific point in time. This position can be the same as the starting or ending point used to determine the speed, or it can be any other point in time. If the position is at the lane level, the target vehicle's current lane can be determined based on that position and lane-level road network data. If the position is at the road level, the road where the target vehicle is located can be determined based on that position, and then the target vehicle's current lane on that road can be further determined based on images captured by the vision device on the target vehicle.

[0082] Another method is to determine the lane where the target vehicle is located based on its position. If the lane is the target lane, the direction of travel indicated by the navigation route is not controlled by traffic lights, and there are vehicles in the target lane in front of the target vehicle whose direction of travel is controlled by traffic lights, then the target vehicle is determined to be in a blocked state.

[0083] Specifically, "vehicles in the target lane whose direction of travel is controlled by traffic lights" refers to vehicles in the target lane that are in front of the target vehicle whose direction of travel is controlled by traffic lights, and the traffic light for that direction is in the target display state, indicating that the vehicle is prohibited from proceeding. In other words, if the target vehicle is traveling in the target lane in a direction not controlled by traffic lights, and if a vehicle in front of the target vehicle in the target lane is in a direction controlled by traffic lights and the traffic light for that direction is in the target display state, it indicates that the vehicle is obstructing the target vehicle's progress, and thus the target vehicle is determined to be in an obstructed state.

[0084] The target vehicle can obtain the driving information of the vehicle ahead from the server, or it can communicate with the vehicle ahead via vehicle-to-everything (V2X) wireless communication technology to obtain the driving information of the vehicle ahead. The driving information of the vehicle ahead may include its direction of travel. Specifically, the target vehicle and the vehicle ahead can communicate with each other via V2X technology, exchanging information such as their own position, speed, and direction.

[0085] Specifically, the server obtains the driving direction of the vehicle in front of the target vehicle and the display status of the traffic light corresponding to that driving direction, and determines whether the driving direction is a traffic light-controlled direction and whether the traffic light display status is the target display status. If the vehicle's driving direction is a traffic light-controlled direction and the traffic light display status is the target display status, a first notification message is sent to the target vehicle's client. This first notification message is used to notify the target vehicle that there is a vehicle in front of it whose driving direction is controlled by the traffic light. This vehicle and the target vehicle are located in the target lane.

[0086] Alternatively, a vehicle ahead of the target vehicle acquires its own driving information and sends a second notification message to the target vehicle. This second notification message informs the target vehicle of its driving information, which indicates that the target vehicle is subject to traffic light control. Specifically, the vehicle ahead can acquire its own position and driving direction, determine whether it is in the target lane based on its position, and determine whether its driving direction is subject to traffic light control. If it is in the target lane and its driving direction is subject to traffic light control, it determines the display status of the nearest intersection's traffic light. If the display status matches the target display status, it sends a second notification message to the target vehicle.

[0087] Among them, the vehicle in front can judge the display status of the traffic light at the nearest intersection in the following way: the vehicle in front requests the server to obtain traffic light information, and then determines the display status of the traffic light based on the obtained traffic light information and the current moment, and judges whether the current display status is the target display status. If so, it indicates that the vehicle itself is controlled by the traffic light and cannot move forward. Among them, the traffic light information may include the display duration corresponding to different display statuses and the display status of the traffic light at the target moment. The display status of the traffic light at the target moment may be the display status of the traffic light corresponding to the moment when the server issues the target passing data to the vehicle in front, or the display status of the traffic light at a preset moment. Specifically, after knowing the display status of the traffic light at a certain moment, the display duration corresponding to different display statuses, and the switching rules between different display statuses, the vehicle in front can determine the display status at the current moment through continuous iteration.

[0088] It should be noted that if the target moment is exactly the starting moment of a certain display status (i.e., the moment of display status change), the display status at the current moment can be directly determined through iteration based on the display status at the target moment, the display duration corresponding to different display statuses, and the switching rules between different display statuses.

[0089] Specifically, the display status at the current moment can be determined by the following formula: t2 = (t1 – t0) % T (1);

[0090] Among them, t1 represents the current moment, t0 represents the moment of signal light change, T represents the signal cycle, which is the sum of the display durations of each display status, % represents the remainder operation, ensuring that t2 is between 0 and T - 1. The signal cycle refers to a complete cycle of the traffic light, which can be the time length from the start of the green light to the start of the green light again. t2 is used to indicate the position of the current moment in the signal cycle, that is, to determine whether the current display is a green light, a yellow light, or a red light through the t2 value.

[0091] If 0 <= t2 < gt, the green light is displayed, where gt represents the green light display duration.

[0092] If gt <= t2 < gt + yt, the yellow light is displayed, where yt represents the yellow light display duration.

[0093] Otherwise, the red light is displayed.

[0094] If the target time is the middle of a certain display state, the traffic light information can also include the displayed duration or remaining display duration of that display state. Then, based on the display state at the target time, the displayed duration or remaining display duration of that display state, the display duration of different display states, and the switching rules between different display states, the display state at the current time is determined iteratively.

[0095] It should be noted that in this case, the time to change to the display state (the display state corresponding to the target time) can be determined first based on the target time and the displayed duration or the remaining display duration, i.e. the change time. Then, t2 can be calculated using the above formula (1), and the display state at the current time can be determined according to the value range of t2.

[0096] Alternatively, if the vehicle ahead is equipped with a vision device, it can also determine the traffic light's display status based on the captured image. Specifically, if the image captured by the vehicle ahead includes the traffic lights at the intersection ahead, it can determine whether the traffic light's display status matches the target display status based on that image. Specifically, image processing algorithms extract traffic light features from the image, such as color and position features, and then machine learning algorithms input the extracted features into a pre-trained model to determine the traffic light's display status.

[0097] 2. When the server determines whether the target vehicle is in a blocked state, the server sends a third notification message to the client after determining that the target vehicle is in a blocked state, so as to notify the client that the target vehicle is in a blocked state through the third notification message.

[0098] The process by which the server determines whether a target vehicle is obstructed may include: determining the lane and direction of travel of the target vehicle; if the target vehicle is in the target lane and its direction of travel is not controlled by traffic lights, obtaining the direction of travel of the vehicle in front of the target vehicle and the display status of the traffic light corresponding to that direction, wherein both the vehicle in front of the target vehicle and the target vehicle are traveling in the target lane; if the vehicle's direction of travel is controlled by traffic lights and the display status of the traffic light corresponding to that direction is the target display status, determining that the target vehicle is obstructed; and sending a third notification message to the client. This third notification message is used to notify the target vehicle that it is obstructed.

[0099] In some implementations, when it is determined that a target vehicle is obstructed, the direction controlled by traffic lights corresponding to the obstructed state is determined, and traffic light information corresponding to that direction is obtained from the target traffic data. Based on the traffic light information, the target traffic light countdown information corresponding to that direction is determined so as to display the target traffic light countdown information corresponding to that direction to the user. The target traffic data includes traffic light information corresponding to the direction controlled by traffic lights that caused the vehicle to be obstructed. Specifically, the target traffic data may include traffic light information corresponding to different directions controlled by traffic lights when the vehicle is obstructed. As mentioned above, the obstruction category indicates the direction controlled by traffic lights that caused the vehicle to be obstructed; therefore, the target traffic data includes at least one obstruction category and traffic light information corresponding to each obstruction category.

[0100] When the target lane includes a traffic-controlled direction, that direction is determined as the traffic-controlled direction that would cause the target vehicle to be obstructed.

[0101] When the target lane includes at least two traffic-light-controlled directions, the traffic light timing information for these different traffic-light-controlled directions may differ. In this scenario, the client can request the direction of travel of the first vehicle in the target lane from the server and determine that direction as the traffic-light-controlled direction that causes the target vehicle to be obstructed. For example, if the target lane allows travel in three directions, one direction is not traffic-light-controlled, and the other two directions are traffic-light-controlled (the timing information for these two directions is different), then when determining that a vehicle is obstructed, it is necessary to determine which traffic-light-controlled direction the vehicle is blocking (i.e., determine the obstruction category) in order to display the traffic light countdown information for that traffic-light-controlled direction to the user.

[0102] Before displaying the target traffic light countdown information, the client determines the target traffic light countdown information based on the target traffic data. Specifically, based on the target vehicle's location, it identifies the traffic light information that is causing the target vehicle's obstruction from the target traffic data. Based on this traffic light information and the current time, it determines the target traffic light countdown information. The current display state of the traffic light causes the target vehicle to be obstructed. The traffic light information includes display durations for different display states, such as red light duration and green light duration, and may also include the traffic light's display state at the target time. The current traffic light display state is the target display state.

[0103] Specifically, the client will determine the countdown information corresponding to the target display state, i.e. the target traffic light countdown information, based on the current time, the target time, the display status of the traffic light, and the display duration corresponding to different display states.

[0104] If the target time happens to be the start time of a certain display state, the countdown information of the target display state can be determined iteratively based on the display state at the target time, the display duration corresponding to different display states, and the switching rules between different display states.

[0105] If the target time is the middle of a certain display state, the traffic light information can also include the displayed duration or remaining display duration of that display state. Based on the display state at the target time, the displayed duration or remaining display duration of that display state, the display duration of different display states, and the switching rules between different display states, the countdown information of the target display state is determined iteratively.

[0106] Specifically, t2 can be calculated using formula (1), and then the remaining display duration can be determined based on t2 and the following formula:

[0107] If the current light is green:

[0108] RT = gt - t2, where RT indicates the remaining duration of the green light;

[0109] If the current light is yellow:

[0110] RT = yt - (t2 - gt), where RT indicates the remaining time of the yellow light;

[0111] If the current display is red:

[0112] RT = rt - (t2 - (gt + yt)), where rt indicates the duration of the red light display and RT indicates the remaining duration of the red light.

[0113] Since the countdown information of the target traffic light displayed in this embodiment is the countdown information under a specific display state, the remaining time corresponding to that specific display state can be determined using the corresponding calculation formula.

[0114] For example, the signal cycle is 120 seconds, the green light lasts for 60 seconds, the yellow light lasts for 5 seconds, and the red light lasts for 55 seconds. The time difference between the current time and the target time is 90 seconds, so t2 = 90. Using formula (1), we can determine that the traffic light is currently red, which is the target display state. Based on the formula for calculating the remaining red light time, we determine RT = 30 seconds.

[0115] Specifically, to distinguish between controlled and obstructed scenarios, traffic light countdown information in obstructed scenarios can be displayed using icons of preset shapes. The preset icons differ in shape from those in controlled scenarios; for example, the icon in a controlled scenario is an arrow, while the icon in an obstructed scenario is a cylinder.

[0116] It is evident that when a vehicle is obstructed, it can provide the obstructed user with a matching countdown timer, allowing the user to clearly understand the countdown timer for the traffic light controlling the direction that is blocking their vehicle's progress, thus improving the user experience.

[0117] Referring to Figure 4, which is a flowchart of a traffic information processing method provided in an embodiment of this disclosure, as shown in Figure 4, the method is applied to a client installed on the target vehicle, or installed on a mobile device on the target vehicle, and includes:

[0118] S401: Send a data request to the server.

[0119] The data request is at least used to request traffic data for the target vehicle in an obstructed scenario, including traffic light information. An obstructed scenario refers to a situation where the vehicle is not controlled by traffic lights when passing through the target lane according to the navigation route, and the target lane includes at least one direction controlled by traffic lights. The data request may include information such as the target vehicle's location and user identifier.

[0120] In this embodiment, the specific implementation of the client sending a data request to the server can be found in the relevant description in S201 of the above method embodiment.

[0121] S402: Receive target passage data sent by the server.

[0122] In this embodiment, after receiving a data request from the client, the server can obtain the traffic light traffic data matching the location of the target vehicle in the data request, and send this traffic data to the client as the target traffic data. Specifically, the target traffic data can be the traffic light traffic data at intersections within a preset distance or a preset number of intersections from the target vehicle. The target traffic data includes traffic light information corresponding to the obstructed scenario for the target vehicle.

[0123] For details on the specific implementation of the server obtaining target access data based on data requests, please refer to the relevant description in S202 of the above method embodiment.

[0124] S403: In response to the target vehicle being obstructed, display the target traffic light countdown information.

[0125] In this embodiment, the client can determine whether the target vehicle is in a blocked state, or the server can determine whether the target vehicle is in a blocked state, and then determine whether the target vehicle is in a blocked state based on the third notification message sent by the server.

[0126] The client determines whether the target vehicle is blocked based on its location and navigation route. Specifically, this can be implemented in the following ways:

[0127] One method is to determine the lane and speed of the target vehicle based on its location; if the lane is the target lane, the direction indicated by the navigation route is not controlled by traffic lights, and the speed of the target vehicle is less than a first preset speed threshold, the target vehicle is determined to be in an obstructed state.

[0128] Another approach is to determine that the target vehicle is in a blocked state if the lane is not the target lane, the target vehicle's speed is less than the second preset speed threshold, and the navigation route indicates that the target vehicle is about to enter the target lane.

[0129] Another method is to determine the lane where the target vehicle is located based on its position. If the lane is the target lane, the direction of travel indicated by the navigation route is not controlled by traffic lights, and there are vehicles in the target lane in front of the target vehicle whose direction of travel is controlled by traffic lights, then the target vehicle is determined to be in a blocked state.

[0130] Before determining that the target vehicle is obstructed, the method further includes: receiving a first notification message sent by a server, the first notification message being used to notify the target vehicle that there is a vehicle ahead whose travel direction is controlled by a traffic light; and / or receiving a second notification message sent by a vehicle ahead of the target vehicle, the second notification message being used to notify the vehicle of its travel information, the travel information indicating that the vehicle is controlled by a traffic light.

[0131] If the server determines whether the target vehicle is in a blocked state, when the server determines that the target vehicle is in a blocked state, it sends a third notification message to the target vehicle's client. This third notification message is used to notify the target vehicle that it is in a blocked state.

[0132] For a detailed description of each of the above implementation methods, please refer to the relevant descriptions in the above embodiments.

[0133] In some implementations, in response to a target vehicle being obstructed, the client displays target traffic light countdown information, including: determining the direction controlled by the traffic light that caused the target vehicle to be obstructed; obtaining traffic light information corresponding to the direction controlled by the traffic light from target traffic data; determining target traffic light countdown information corresponding to the direction controlled by the traffic light based on the traffic light information; and displaying the target traffic light countdown information. The target traffic data includes traffic light information corresponding to the direction controlled by the traffic light that caused the vehicle to be obstructed.

[0134] The target traffic light countdown information is determined based on target traffic data. This determination process includes: identifying the traffic light information that causes the target vehicle to be obstructed from the target traffic data based on the target vehicle's position; and determining the target traffic light countdown information based on the traffic light information and the current time. The traffic light information includes the display duration corresponding to different display states and the display state of the traffic light at the target time. For a detailed description of the specific implementation of determining the target traffic light countdown information, please refer to the relevant description in the method embodiment shown in Figure 2 above.

[0135] Referring to Figure 5, which is a flowchart of another traffic information processing method provided in this embodiment of the present disclosure, as shown in Figure 5, this method is applied to a server, which is used to provide navigation-related services to the aforementioned client, including:

[0136] S501: Receive a data request from the client, which is at least used to request the target vehicle's passage data in the obstructed scenario.

[0137] The traffic data includes traffic light information. The obstruction scenario refers to a situation where a vehicle is not controlled by traffic lights when it passes through the target lane according to the navigation route, and the direction of travel in the target lane also includes at least one direction controlled by traffic lights.

[0138] S502: Determine the target passage data based on the data request.

[0139] The target traffic data includes traffic light information corresponding to the target vehicle in the obstructed scenario, and the traffic light information includes the timing information of the traffic light.

[0140] Among them, determining the target traffic data according to the data request includes: based on the location of the target vehicle in the data request, obtaining the traffic data of traffic lights at intersections within a preset distance or a preset number of intersections from that location as the target traffic data.

[0141] For a detailed description of the implementation of S502, please refer to the relevant description of S202 in the above method embodiment.

[0142] S503: Send target passage data to the client.

[0143] After obtaining the target traffic data, the server sends the target traffic data to the client so that when the target vehicle is blocked, the client can display the target traffic light countdown information to the user.

[0144] In some implementations, the server can obtain the driving direction of the vehicle in front of the target vehicle and the display status of the traffic light corresponding to that driving direction; if the driving direction of the vehicle is a direction controlled by the traffic light and the display status of the traffic light corresponding to that direction is the target display status, the server sends a first notification message to the client, which is used to notify the target vehicle that there is a vehicle in front of the target vehicle whose driving direction is controlled by the traffic light.

[0145] Additionally, the server can determine whether the target vehicle is obstructed. Specifically, it determines the lane and direction of travel of the target vehicle. If the lane is the target lane and the direction of travel is not controlled by traffic lights, it obtains the direction of travel of the vehicles in front of the target vehicle and the display status of the traffic lights corresponding to that direction, wherein both the target vehicle and the vehicles are traveling in the target lane. If the vehicle's direction of travel is controlled by traffic lights and the display status of the traffic light corresponding to that direction is the target display status, it determines that the target vehicle is obstructed. A third notification message is then sent to the client to notify that the target vehicle is obstructed. The target display status indicates that vehicles in front of the target vehicle are prohibited from passing.
