Description

Technical Field

[0001] The present application relates to the technical field of intelligent transportation and urban road planning, and in particular to a lane tidal conversion system for entrances and exits of large public buildings. Background Art

[0002] With the acceleration of urbanization, large public buildings such as hospitals, stadiums, transportation hubs, and performance venues are experiencing increasing passenger traffic. This significantly increases traffic pressure in these areas, especially during evacuation periods. While existing methods for adjusting tidal traffic lanes on urban arterial roads have alleviated traffic pressure to some extent, they lack a method for managing tidal traffic in the specific passenger pick-up and drop-off areas of these large public buildings.

[0003] Specifically, large public buildings generally utilize the innermost lanes for passenger drop-off. This practice can interfere with vehicles in adjacent lanes during periods of heavy traffic, leading to longer drop-off and departure times, which in turn impacts overall traffic efficiency and causes congestion. Current traffic signal control devices lack flexibility and are unable to adjust traffic flow based on the lanes and drop-off methods of large public buildings. This results in congestion at the entrances and exits of large public buildings during peak traffic periods, and ineffective utilization of existing idle lanes during low traffic periods. Large buildings typically have numerous adjacent lanes, and if these lanes are not effectively utilized, this can result in a significant waste of traffic resources.

[0004] Therefore, how to adjust the direction of traffic flow according to the characteristics of the entrances and exits of large public buildings and the current traffic situation to improve the utilization rate of lanes and drop-off berths is an urgent problem that needs to be solved. Summary of the Invention

[0005] The present application provides a lane tidal conversion system for the entrances and exits of large public buildings. Through data linkage between signal processing devices at the entrances of each lane, the drivable direction of the lane can be changed according to the congestion status of traffic in different time periods, thereby achieving the effect of "tidal traffic organization" and alleviating municipal traffic congestion around large public buildings.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a lane tidal conversion system for the entrance and exit of a large public building, comprising:

[0010] The drop-off berth acquisition module is provided at the intersection of the first to Nth entrance lanes and the drop-off lanes, and is used to acquire images of the drop-off berths and calculate the number of available drop-off berths in the images of the drop-off berths based on a preset drop-off berth shape;

[0011] The traffic adjustment module includes a signal processing device arranged at the intersection of the first to Nth entrance lanes and the drop-off lane, which is used to adjust the traffic signal display content according to the traffic status image to control the drivable direction of the lane and display the number of available drop-off berths.

[0013] Identifying the congestion status of each lane from the first to the Nth entrance lanes according to an image recognition algorithm to obtain the congestion status of the Nth lane;

[0014] When the traffic state of the Nth entrance lane is identified as congested, the direction of traffic exiting the large public building from this entrance lane is blocked, and a congestion signal is sent to the signal processing device and the passenger drop-off space collection module at the intersection of the N+1th entrance lane and the passenger drop-off lane;

[0015] After receiving the congestion signal, the signal processing device at the intersection of the N+1th entrance lane and the drop-off lane opens the N+1th entrance lane as an entrance lane and closes its direction of exiting the large public building.

[0016] In a preferred example of the present application, it can be further configured to include:

[0017] After receiving the congestion signal, the drop-off berth acquisition module at the intersection of the N+1th entrance lane and the drop-off lane acquires images of the drop-off berths between the intersections of the Nth to N+1th entrance lanes and the drop-off lanes.

[0018] In a preferred example of the present application, it can be further configured that the display of the number of available drop-off berths includes:

[0019] Displaying available drop-off berths between the intersections of the Nth to N+1th entrance lanes and the drop-off lane;

[0020] The available drop-off berths between the intersections of the 1st to N+1th entrance lanes and the drop-off lane are displayed.

[0021] In a preferred example of the present application, it can be further configured that the shape of the preset drop-off berth includes:

[0024] The curb edge of the drop-off area is serrated and includes a berth adjacent edge and a separation edge; the berth adjacent edge is adjacent to and parallel to the long side of the berth;

[0025] The isolation boundary line connects adjacent boundary lines of the berths and is inclined counterclockwise relative to the lane boundary line of the passenger drop-off lane.

[0026] In a preferred example of the present application, it can be further configured that the adjusting of traffic signal display content according to the traffic flow status image further includes:

[0027] When the traffic flow state of the Nth entrance lane is identified as stop congestion, the entrance lane is opened to traffic exiting the large public building, the Nth entrance lane is closed as an entrance lane, and a stop congestion signal is sent to the signal processing device at the intersection of the N-1th entrance lane and the drop-off lane and the drop-off berth collection module at the intersection of the Nth entrance lane and the drop-off lane;

[0028] After receiving the stop congestion signal, the signal processing device at the intersection of the N-1th entrance lane and the drop-off lane opens the direction for exiting the large public building.

[0029] In a preferred example of the present application, it can be further configured that the passenger drop-off berth acquisition module at the intersection of the Nth entrance lane and the passenger drop-off lane stops acquiring images of the passenger drop-off berth after receiving the stop congestion signal.

[0030] In a preferred example of the present application, it can be further configured that the traffic adjustment module further includes:

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] In one embodiment of the present application, a lane tidal conversion system for the entrance and exit of a large public building is provided. Figure 1 Shown, including:

[0045] Lane image acquisition module 100, passenger drop-off space acquisition module 200 and traffic adjustment module 300;

[0046] The lane image acquisition module is used to capture traffic flow images including the 1st to Nth entrance lanes, the drop-off lanes, and the building perimeter lanes; the drop-off lanes intersect perpendicularly with the building perimeter lanes, and both are adjacent to the building area; the 1st to Nth entrance lanes intersect perpendicularly with the drop-off lanes on the side not adjacent to the building area, and the 1st entrance lane intersects the drop-off lane between the building drop-off area and the building perimeter lanes; from the 1st to the N-1th entrance lanes, the intersections with the drop-off lanes gradually approach the building perimeter lanes; the Nth entrance lane is connected to the building perimeter lanes; and the drop-off lanes are adjacent to the building drop-off area.

[0047] The drop-off berth acquisition module is provided at the intersection of the first to Nth entrance lanes and the drop-off lanes, and is used to acquire images of the drop-off berths and calculate the number of available drop-off berths in the images of the drop-off berths based on a preset drop-off berth shape;

[0048] The traffic adjustment module includes a signal processing device arranged at the intersection of the first to Nth entrance lanes and the drop-off lane, which is used to adjust the traffic signal display content according to the traffic status image to control the drivable direction of the lane and display the number of available drop-off berths.

[0049] For specific implementation, please refer to Figure 2 As shown in the figure, entrance 1, entrance 2 and entrance N are the 1st to Nth entrance lanes. The drop-off lane between the building drop-off area and the building peripheral lane is the drop-off lane included in the area between the extension line of the right edge line of the building drop-off area and the right edge line of the building peripheral lane. The N-1th entrance lane is the entrance lane with the serial number N minus 1. This embodiment is applied to Figure 2The vehicle flow direction of the lane structure shown is adjusted. The passenger drop-off berth collection module is located close to the traffic adjustment module.

[0050] The lane image acquisition module collects traffic status images through cameras distributed around each lane and sends them to the traffic adjustment module. The traffic adjustment module identifies vehicles in the image based on existing image recognition technology and determines whether there is congestion based on a preset threshold.

[0051] The signal processing device may be a computing device, an integrated circuit, or other device that can process digital signals, without limitation.

[0052] The traffic adjustment module is used to process the data sent by the passenger drop-off space acquisition module and the lane image acquisition module, and open or close the corresponding first to Nth entrance lanes based on the analysis results, that is, adjust the traffic direction of each entrance lane. The traffic signal display content can be a traffic light, a flip sign, etc., which is not limited in this embodiment.

[0053] like Figure 2 As shown, the traffic direction of the entrance lane can be left turn or right turn, left turn is to enter the drop-off area of ​​the building, right turn is to exit the large public building, and the traffic direction of exiting the large public building can be right turn Figure 2 Specifically, when traffic is not congested, the first entrance lane is opened as the main entrance, and lanes 2 to N are closed or only open to the direction of the non-building drop-off area. When the traffic volume exceeds the preset threshold corresponding to N, the entrance lane of lane N is opened to the building drop-off area, and lanes 1 to N-1 are closed. The larger N is, the higher the preset threshold is. When traffic volume drops back to a lower threshold, the Nth entrance lane is closed, the entrance lane corresponding to the lower threshold is opened, and all entrance lanes with a sequence number lower than the lower threshold are closed.

[0054] When the traffic flow state of the Nth entrance lane is congested, adjusting the traffic signal display content according to the traffic flow status image includes:

[0055] Identifying the congestion status of each lane from the first to the Nth entrance lanes according to an image recognition algorithm to obtain the congestion status of the Nth lane;

[0056] When the traffic state of the Nth entrance lane is identified as congested, the direction of traffic exiting the large public building from this entrance lane is blocked, and a congestion signal is sent to the signal processing device and the passenger drop-off space collection module at the intersection of the N+1th entrance lane and the passenger drop-off lane;

[0057] After receiving the congestion signal, the signal processing device at the intersection of the N+1th entrance lane and the drop-off lane opens the N+1th entrance lane as an entrance lane and closes its direction of exiting the large public building.

[0058] When the entrance lane 1 is not congested, the accessible directions of each lane are as follows: Figure 3 When the entrance lanes 1 to N-1 are in a congested state, the traffic adjustment device adjusts the traffic flow direction of each lane, and the passable direction is as follows Figure 3 shown.

[0059] When the traffic flow state of the Nth entrance lane stops being congested, adjusting the traffic signal display content according to the traffic flow status image includes:

[0060] When the traffic flow state of the Nth entrance lane is identified as stop congestion, the entrance lane is opened to traffic exiting the large public building, the Nth entrance lane is closed as an entrance lane, and a stop congestion signal is sent to the signal processing device at the intersection of the N-1th entrance lane and the drop-off lane and the drop-off berth collection module at the intersection of the Nth entrance lane and the drop-off lane;

[0061] After receiving the stop congestion signal, the signal processing device at the intersection of the N-1th entrance lane and the drop-off lane opens the direction for exiting the large public building.

[0062] In this embodiment, when the volume of passenger drop-off traffic at the entrance and exit lanes of a large public building exceeds an upper threshold, traffic can be redirected to create additional entrance lanes, preventing traffic congestion caused by reverse flow and extending the length of the waiting area at the lane edge. By linking data between the signal processing devices at each lane entrance, the lane's drivable direction can be adjusted based on traffic congestion at different time periods, achieving a "tidal traffic organization" effect and alleviating municipal traffic congestion around large public buildings.

[0063] In some embodiments, after receiving the congestion signal, the drop-off berth acquisition module at the intersection of the N+1th entrance lane and the drop-off lane acquires images of the drop-off berths between the intersections of the Nth to N+1th entrance lanes and the drop-off lane.

[0064] The passenger drop-off space acquisition module at the intersection of the Nth entrance lane and the passenger drop-off lane stops acquiring images of the passenger drop-off space after receiving the stop congestion signal.

[0065] In this embodiment, the corresponding passenger drop-off space collection module is activated only when the length of the waiting area for passenger drop-off on the side of the lane is extended, which is beneficial to saving energy.

[0066] In some embodiments, the shape of the preset drop-off berth is as follows: Figure 5 Shown, including:

[0067] Rectangular berth and drop-off area curb lines located in the building drop-off area;

[0068] The berth is inclined clockwise relative to the lane edge of the drop-off lane, and the angle between its long side and the lane edge of the drop-off lane is smaller than the short side, and the angle is acute;

[0069] The curb edge of the drop-off area is serrated and includes a berth adjacent edge and a separation edge; the berth adjacent edge is adjacent to and parallel to the long side of the berth;

[0070] The isolation boundary line connects adjacent boundary lines of the berths and is inclined counterclockwise relative to the lane boundary line of the passenger drop-off lane.

[0071] In this embodiment, by providing zigzag-shaped drop-off berths in the building drop-off area, interference with vehicles in adjacent lanes is reduced, thereby shortening the time required for drop-off and vehicle departure, and alleviating traffic congestion.

[0072] In some embodiments, the traffic adjustment module further includes:

[0073] The countdown display screen is used to display the remaining time for switching the lane's passable direction according to the instructions sent by the signal processing device.

[0074] In a specific implementation, when the traffic adjustment module is about to adjust the traffic signal display content, the remaining time to the moment of switching lane direction is displayed in the form of a countdown.

[0075] In this embodiment, prompting the driver can help reduce the probability of traffic accidents caused by confusion in driving direction.

[0076] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-mentioned embodiments only express several implementation methods of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, several variations and improvements can be made, which all fall within the scope of protection of the present application. Therefore, the scope of protection of the patent of this application shall be based on the attached claims.
