Description

[0002] With the continuous growth of urban traffic flow, the efficiency of intersections has become a key factor restricting urban traffic operation. Lane borrowing for turning, a common technology to improve the turning capacity of intersections, essentially involves setting up dedicated lanes at the intersection entrances, allowing turning vehicles to temporarily use the oncoming lanes to complete their turns, thereby reducing interference with through traffic. However, existing lane borrowing technologies, due to the single entrance, only allow a small number of vehicles to enter the lane within a single signal cycle. Most turning vehicles still need to queue in their original lanes, limiting the actual efficiency improvement and failing to fully realize the traffic optimization potential of lane borrowing technology.

Detailed Implementation
[0024] To make the above-mentioned objectives, features and advantages of the embodiments of this application more apparent and understandable, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0025] To facilitate understanding and explanation of the technical solutions provided in the embodiments of this application, the background technology of the embodiments of this application will be described first below.
[0026] Existing lane-sharing turning technologies, due to their single entry point, only allow a small number of vehicles to enter the lane within a single signal cycle. Most turning vehicles still need to queue in their original lanes, limiting the actual traffic efficiency improvement and failing to fully realize the traffic optimization potential of this technology. Furthermore, current lane-sharing guidance methods largely rely on static signs and markings. In complex traffic environments or inclement weather, drivers may find it difficult to clearly determine lane-sharing permissions, impacting not only traffic efficiency but also posing significant traffic safety hazards.
[0027] Based on this, the embodiments of this application provide a parallel lane-sharing turning traffic guidance method, system, device and equipment. By setting multiple first lane-sharing turning pre-positioned parking spaces in the turning lane adjacent to the lane-sharing turning lane, vehicles can enter the lane-sharing turning lane in parallel using the first lane-sharing turning pre-positioned parking spaces. Combined with dynamic visualization guidance methods, this solves the problems of low efficiency and unclear guidance of existing single-entry lane-sharing turning, which will be of great significance to improving the traffic capacity of intersections.
[0028] To facilitate understanding of the parallel lane-changing traffic guidance method provided in this application embodiment, the following description is provided in conjunction with the scenario example shown in Figure 1. Referring to Figure 1, this figure is a schematic diagram of an exemplary application scenario provided in this application embodiment.
[0029] In this embodiment, a first pre-designated parking space for using the bypass turn is provided in the turning lane, such as a left-turn lane. The turning lane is adjacent to the bypass turn lane, which is, for example, a straight-ahead lane adjacent to the left-turn lane. When bypass turn is permitted, vehicles can use the open first pre-designated parking space, and vehicles in one or more open first pre-designated parking spaces can simultaneously enter the bypass turn lane. This embodiment can guide the use of the first pre-designated parking space by controlling the guidance device of the first pre-designated parking space, thereby guiding the bypass turn process and improving the traffic efficiency of bypass turn.
[0030] Those skilled in the art will understand that the schematic diagram shown in Figure 1 is merely an example in which embodiments of this application can be implemented. The scope of application of the embodiments of this application is not limited by any aspect of this framework.
[0031] To facilitate understanding of the embodiments of this application, the following description, in conjunction with the accompanying drawings, illustrates a parallel lane-borrowing traffic guidance method provided by the embodiments of this application.
[0032] Referring to Figure 2, which is a flowchart of a parallel lane-borrowing turning traffic guidance method provided in an embodiment of this application, as shown in Figure 2, the method may include S201-S202: S201: Obtain the lane-borrowing turning signal status.
[0033] On roads with lane-sharing turning capabilities, the road signal control system can determine the lane-sharing turning signal status. A "lane-sharing permitted" status means the lane-sharing turning lane is currently usable, while a "lane-sharing prohibited" status means the lane-sharing turning lane is currently not permitted. Obtaining the lane-sharing turning signal status first serves as the basis for subsequent control.
[0034] S202: Based on the status of the lane-borrowing turn signal, control the guidance device corresponding to the first pre-set lane-borrowing turn space to guide the usage status of the first pre-set lane-borrowing turn space; the first pre-set lane-borrowing turn space is set in the turn lane adjacent to the lane-borrowing turn lane, and the first pre-set lane-borrowing turn space is connected to the lane-borrowing turn lane; the position or size of the first pre-set lane-borrowing turn space is determined according to the vehicle's turning motion space.
[0035] In this embodiment, multiple first pre-positioned parking spaces for detour turning are provided on the turning lane adjacent to the detour turning lane. These first pre-positioned parking spaces are connected to the detour turning lane, allowing vehicles entering the first pre-positioned parking space to enter the detour turning lane when the detour turning signal is enabled. The position or size of the first pre-positioned parking space is determined based on the vehicle's turning space. The vehicle turning space takes into account the differences between different vehicle models, ensuring that vehicles of all models can use the first pre-positioned parking spaces to enter the detour turning lane when redundancy is available.
[0036] Each designated first-lane turning pre-positioned parking space can be equipped with a guiding device to identify its location. In one possible implementation, the guiding device can be a light-emitting device, such as a luminous floor tile, installed on the ground of each designated first-lane turning pre-positioned parking space. The light-emitting device can indicate information such as the parking space lines and usage status of the designated first-lane turning pre-positioned parking space. Unlike static markings, using guiding devices to identify the location of designated first-lane turning pre-positioned parking spaces is clearer and can indicate different usage statuses of the designated first-lane turning pre-positioned parking spaces.
[0037] Based on the status of the lane-sharing turn signal, the first pre-set lane-sharing turn space that is open can be determined. This first pre-set lane-sharing turn space can be one or more of the following: The guidance device corresponding to the open first pre-set lane-sharing turn space can guide the usage status of that space.
[0038] One possible implementation may also include: A1: obtaining road traffic flow.
[0039] A2: Based on road traffic flow, the target number of pre-positioned parking spaces for the first lane to turn is determined as the number of pre-positioned parking spaces for the first lane to turn starting from the front end of the road. The target number is positively correlated with the road traffic flow and is less than or equal to the number of pre-positioned parking spaces for the first lane to turn.
[0040] In practical applications, the target number of pre-positioned first-lane turning spaces can be determined based on road traffic flow. Generally, this can be started from the beginning of the road, with the target number of pre-positioned first-lane turning spaces designated as the open spaces. The target number is positively correlated with road traffic flow; the higher the traffic flow, the more pre-positioned first-lane turning spaces can be opened, up to a maximum of all pre-positioned first-lane turning spaces. This allows more vehicles to simultaneously turn in parallel when traffic is heavy.
[0041] In this embodiment, a first pre-positioned parking space for bypassing the turning lane is provided in the adjacent turning lane. The position or size of the first pre-positioned parking space is determined according to the vehicle's turning space, allowing vehicles within the first pre-positioned parking space to smoothly enter the turning lane. Each first pre-positioned parking space is equipped with a guidance device that acquires the turning signal status. Based on the turning signal status, the guidance device corresponding to the open first pre-positioned parking space can be controlled to guide the use of the open first pre-positioned parking space. This guides vehicles to use the first pre-positioned parking space, allowing vehicles to simultaneously enter the turning lane from multiple first pre-positioned parking spaces. Dynamic guidance through the guidance device makes the turning process clearer and improves the efficiency of bypassing the turning lane.
[0042] In one possible implementation, S202 controls the guidance device corresponding to the first pre-set pre-set parking space to guide the use status of the first pre-set pre-set parking space according to the status of the pre-set ...
[0043] When the lane-sharing turn signal status is "lane-sharing permitted," the guiding device corresponding to the first pre-set lane-sharing turn space that is controlled to be open is in a guiding state, indicating that lane-sharing turn is currently permitted, and vehicles in the currently open first pre-set lane-sharing turn space can enter the lane-sharing turn lane. For example, the illuminated paving stone corresponding to the first pre-set lane-sharing turn space that is controlled to be open is green, causing the exit line of the first pre-set lane-sharing turn space to display green as a guiding state.
[0044] B2: Control the guiding device corresponding to the unopened first bypass turning pre-positioned parking space to the first closed state, so as to guide the vehicle to drive into the open first bypass turning pre-positioned parking space.
[0045] When the lane-sharing turn signal is in the "lane-sharing permitted" state, for the first pre-set lane-sharing parking space that is not yet open, the guiding device corresponding to the first pre-set lane-sharing parking space is controlled to be in the first closed state. This means that vehicles cannot use the unopened first pre-set lane-sharing parking space to make a lane-sharing turn, and must be guided to drive into the open first pre-set lane-sharing parking space to make a lane-sharing turn. For example, the illuminated paving stones corresponding to the open first pre-set lane-sharing parking space are controlled to display a different color to distinguish them from the open first pre-set lane-sharing parking space.
[0046] In one possible implementation, it may also include: B3: If the lane-borrowing turn signal status is lane-borrowing turn prohibited, control the guiding device corresponding to the first lane-borrowing turn preset parking space to a second closed state, so as to display the location of the first lane-borrowing turn preset parking space and prompt the vehicle to wait in the first lane-borrowing turn preset parking space.
[0047] When the lane-changing turn signal is in the "lane-changing turn prohibited" state, the guiding device corresponding to the first lane-changing turn preset parking space is in the second closed state, meaning that lane-changing turn is currently not allowed, but vehicles can enter the first lane-changing turn preset parking space and must wait within the first lane-changing turn preset parking space for lane-changing turn to be permitted. For example, the illuminated paving stone corresponding to the first lane-changing turn preset parking space is displayed in red, causing the exit line of the first lane-changing turn preset parking space to display in red as the second closed state.
[0048] This allows for dynamic guidance of the lane-changing and turning process under different conditions through the guidance equipment, thereby improving vehicle traffic efficiency and ensuring safety.
[0049] In one possible implementation, it may also include: C1: When a fault is detected, determine that all first-passage turning preset parking spaces are in a closed state.
[0050] C2: Control the guiding device corresponding to the first pre-set parking space for bypassing the turn to the third closed state, so as to cancel the display of the location of the first pre-set parking space for bypassing the turn and prompt the vehicle that bypassing the turn is prohibited.
[0051] When a fault is detected, lane-borrowing turning will no longer be attempted. At this time, the guidance device corresponding to the first pre-set lane-borrowing turning space will be switched to a third closed state, thus de-displaying the location of the first pre-set lane-borrowing turning space. For example, the illuminated tiles corresponding to each pre-set lane-borrowing turning space can be turned off; the first pre-set lane-borrowing turning space will no longer be displayed, and the lane-borrowing turning lane will not be open; vehicles will only use the turning lane. This ensures vehicle driving safety during fault conditions.
[0052] Referring to Figure 3, this figure is a schematic diagram of another exemplary application scenario provided by an embodiment of this application.
[0053] In this embodiment, a first pre-positioned parking space for using the bypass turning lane is provided in a turning lane, such as a left-turn lane. The turning lane is adjacent to the bypass turning lane, which is, for example, a straight-ahead lane adjacent to the left-turn lane. In some road conditions, there is a large space between the turning lane and the bypass turning lane, so a second pre-positioned parking space for using the bypass turning lane is provided in the space between the bypass turning lane and the adjacent turning lane, and the second pre-positioned parking space for using the bypass turning lane is also connected to the bypass turning lane. When bypass turning is prohibited, vehicles can be guided into the second pre-positioned parking space for waiting by controlling the guidance device of the second pre-positioned parking space. At the same time, other vehicles can be guided into the first pre-positioned parking space for waiting by controlling the guidance device of the first pre-positioned parking space for using the bypass turning lane.
[0054] When lane-sharing turning is permitted, vehicles can use both the first and second open lane-sharing turning pre-positioned parking spaces. Vehicles within these spaces can simultaneously enter the lane-sharing turning lane. This embodiment of the application can guide the use of the first and second lane-sharing turning pre-positioned parking spaces by controlling their guiding devices, thereby guiding the lane-sharing turning process and further improving the traffic efficiency of lane-sharing turning.
[0055] Those skilled in the art will understand that the schematic diagram shown in Figure 3 is merely an example in which embodiments of this application can be implemented. The scope of application of the embodiments of this application is not limited by any aspect of this framework.
[0056] Based on the above embodiments, in one possible implementation, the parallel lane-sharing turning traffic guidance method provided in this application embodiment may further include: controlling the guidance device corresponding to the open second lane-sharing pre-positioned parking space according to the lane-sharing turning signal status, and guiding the usage status of the open second lane-sharing pre-positioned parking space; the second lane-sharing pre-positioned parking space is set in the space between the lane-sharing turning lane and the adjacent turning lane, and the second lane-sharing pre-positioned parking space is connected to the lane-sharing turning lane; the position or size of the second lane-sharing pre-positioned parking space is determined according to the vehicle turning motion space.
[0057] In this embodiment of the application, when there is a large space between the detour turning lane and the adjacent turning lane, in order to make full use of the space and further improve the communication efficiency of detour turning, multiple second detour turning pre-positioned parking spaces can be set in the space between the detour turning lane and the adjacent turning lane. The second detour turning pre-positioned parking spaces are connected to the detour turning lane, and the second detour turning pre-positioned parking spaces can be aligned with the first detour turning pre-positioned parking spaces.
[0058] Therefore, vehicles entering the second pre-set lane for bypassing turns can proceed into the bypass lane if the lane-bypassing turn signal is in effect. The location or size of the second pre-set lane for bypassing turns is determined based on the vehicle's turning space. This turning space takes into account the differences between different vehicle models, ensuring that vehicles of all models can use the second pre-set lane for bypassing turns to enter the bypass lane when redundancy is available.
[0059] Each pre-positioned second-lane turning parking space can also be equipped with a guiding device to identify its location. In one possible implementation, the guiding device can be a light-emitting device, such as a luminous floor tile, installed on the ground of each pre-positioned second-lane turning parking space. The light-emitting device can indicate information such as the parking lines and usage status of the pre-positioned second-lane turning parking space. Using a guiding device to identify the location of the pre-positioned second-lane turning parking space is clearer and can indicate different usage statuses of the pre-positioned second-lane turning parking space.
[0060] Based on the status of the lane-sharing turn signal, the open second lane-sharing turn preset parking space can be determined. The open second lane-sharing turn preset parking space can be one or more of the following: The guidance device corresponding to the open second lane-sharing turn preset parking space can guide the usage status of that space.
[0061] Similarly, the target number of pre-positioned second-lane turning spaces can be determined based on road traffic flow. Generally, this can be started from the front of the road, setting the target number of pre-positioned second-lane turning spaces as the available spaces. The target number is positively correlated with road traffic flow; the higher the traffic flow, the more pre-positioned second-lane turning spaces can be opened, up to a maximum of all pre-positioned second-lane turning spaces can be opened.
[0062] In one possible implementation, the specific implementation of controlling the guidance device corresponding to the open second pre-set parking space according to the state of the lane-borrowing turn signal to guide the use status of the open second pre-set parking space may include: D1: If the state of the lane-borrowing turn signal is lane-borrowing turn release, the guidance device corresponding to the open second pre-set parking space is controlled to be in the guidance state, so as to guide vehicles entering the open second pre-set parking space to use the lane for turning.
[0063] When the lane-sharing turn signal is in the "lane-sharing turn permitted" state, the guiding device corresponding to the second pre-set lane-sharing turn space is in a guiding state, indicating that lane-sharing turn is currently permitted, and vehicles in the currently open second pre-set lane-sharing turn space can enter the lane-sharing turn lane. For example, the illuminated paving stone corresponding to the second pre-set lane-sharing turn space is green, causing the exit line of the second pre-set lane-sharing turn space to display green as a guiding state. That is, vehicles in both the currently open first and second pre-set lane-sharing turn spaces can enter the lane-sharing turn lane.
[0064] D2: Control the guiding equipment corresponding to the unopened second-lane turning pre-positioned parking space to the first closed state, so as to guide the vehicle to drive into the open second-lane turning pre-positioned parking space.
[0065] When the lane-borrowing turn signal status is "lane-borrowing permitted," for pre-set second lane-borrowing turn spaces that are not yet open, the guiding device corresponding to the pre-set second lane-borrowing turn space is controlled to the first closed state. This means that vehicles cannot use the pre-set second lane-borrowing turn space for lane-borrowing turn; they must be guided to enter an open second lane-borrowing turn space to make the turn. For example, the illuminated paving stones corresponding to the open second lane-borrowing turn space are controlled to display a different color to distinguish them from the open second lane-borrowing turn space.
[0066] In one possible implementation, it may also include: D3: If the lane-borrowing turn signal status is lane-borrowing turn prohibited, control the guiding device corresponding to the second lane-borrowing turn preset parking space to a second closed state, so as to display the location of the second lane-borrowing turn preset parking space and prompt the vehicle to drive from the turning lane into the second lane-borrowing turn preset parking space and wait in the second lane-borrowing turn preset parking space.
[0067] When the lane-changing turn signal is in the "lane-changing turn prohibited" state, the guiding device corresponding to the second lane-changing turn pre-set parking space is in the second closed state, meaning that lane-changing turn is currently not allowed, but vehicles can enter the second lane-changing turn pre-set parking space and wait within it for lane-changing turn permission to be granted. For example, if the illuminated paving stone corresponding to the open second lane-changing turn pre-set parking space is displayed in red, causing the exit line of the second lane-changing turn pre-set parking space to also be displayed in red as the second closed state, then the current vehicle will have priority to enter the second lane-changing turn pre-set parking space to wait, and subsequent vehicles can then enter the first lane-changing turn pre-set parking space to wait.
[0068] This allows for dynamic guidance of the lane-changing and turning process under different conditions through the guidance equipment, thereby improving vehicle traffic efficiency and ensuring safety.
[0069] In one possible implementation, it may also include: E1: When a fault is detected, determine that all second-passage turning preset parking spaces are in a closed state.
[0070] E2: Control the guiding device corresponding to the second pre-set parking space to the third closed state, so as to cancel the display of the location of the second pre-set parking space and prompt the vehicle that it is prohibited to turn by using the lane.
[0071] When a fault is detected, lane-borrowing turning will no longer be attempted. At this time, the guidance device corresponding to the second pre-set lane-borrowing turning space will be switched to a third closed state, thus canceling the display of the second pre-set lane-borrowing turning space's location. For example, the illuminated tiles corresponding to each pre-set lane-borrowing turning space can be turned off; in this case, the second pre-set lane-borrowing turning space will no longer be displayed, and the lane-borrowing turning lane will not be open; vehicles will only use the turning lane. This ensures vehicle driving safety during fault conditions.
[0072] Based on the above embodiments, in one possible implementation, it may further include: controlling the guidance display device to display the status of the detour turn signal, the usage status of the first detour turn preset parking space and / or the second detour turn preset parking space, wherein the guidance display device is set at the front end of the first detour turn preset parking space.
[0073] Additionally, a guidance display device can be installed at the very front of the first pre-positioned lane-changing turning space, near the stop line at the front of the road. This device, such as a display screen, can show the lane-changing turning signal status and / or the availability of the first and second pre-positioned lane-changing turning spaces through text and / or images. This allows drivers to better understand the current lane-changing turning situation, ensuring vehicle safety.
[0074] Based on the parallel lane-changing turning traffic guidance method provided in the above-described method embodiments, this application also provides a parallel lane-changing turning traffic guidance system, which will be described below with reference to the accompanying drawings.
[0075] Referring to Figure 4, this figure is a structural schematic diagram of a parallel lane-changing traffic guidance system provided in an embodiment of this application. As shown in Figure 4, the parallel lane-changing traffic guidance system includes: a control module 401 and a guidance device 402, the guidance device 402 being disposed on the ground of each first lane-changing pre-set parking space; the control module 401 is used to execute the lane-changing traffic guidance method as described above.
