Description

Technical Field

[0001] This invention relates to the field of traffic control technology, and in particular to a method and system for managing temporary traffic in emergency lanes on highways. Background Technology

[0002] With economic development and increasingly frequent intercity transportation, highway traffic volume is constantly increasing. During peak holiday periods, high traffic volume has become the norm, leading to more frequent highway congestion. Temporary use of emergency lanes has become a crucial method both domestically and internationally to alleviate the sharp drop in service levels at bottlenecks with saturated traffic flow. It can provide road supply in a short time, effectively improving the capacity of bottleneck sections. Furthermore, with the development of vehicle-road cooperative technology and the further application of communication technologies such as 5G in the transportation industry, managers can obtain real-time data on highway traffic flow, speed, vehicle density, and occupancy. By acquiring dynamic, all-weather traffic information and utilizing vehicle-road cooperative technology, emergency lanes can be opened in a coordinated manner based on traffic conditions in highway mainline areas, improving traffic efficiency while ensuring safety and maximizing mainline traffic flow.

[0003] Regarding the temporary traffic control of emergency lanes on highways, European and American scholars have conducted comprehensive research on the opening and use of emergency lanes, and have begun to implement temporary shoulder use measures on some highways to address congestion. Research mainly focuses on the usage patterns, traffic efficiency, congestion mitigation, safety impacts, and operational management measures of emergency lanes. There is relatively little research on the temporary opening strategies of highway emergency lanes from a management perspective, resulting in the ineffective and unreasonable application of highway emergency lanes and the lack of effective alleviation of traffic congestion.

[0004] Therefore, it is necessary to propose a management method and system for temporary traffic in the emergency lane of highways to solve or at least alleviate the above-mentioned defects. Summary of the Invention

[0019] S515, determine the estimated smooth traffic duration from the accident location to the end of the target controlled road section according to a preset algorithm, and send the estimated smooth traffic duration and the end of the target controlled road section to the vehicle terminal traveling between the accident location and the end of the target controlled road section for the vehicle owner's reference.

[0020] Preferably, step S511 is followed by the step:

[0021] S5111, after the target controlled road section is opened, if no traffic accident occurs on the target controlled road section, the congestion index of the emergency lane of the target controlled road section is continuously monitored;

[0022] S5112, when the congestion index of the emergency lane is greater than the preset threshold of the emergency lane, guide vehicles located in the target control section to leave the target control section and close the target control section.

[0023] Preferably, the "emergency lane congestion index" in step S5111 is obtained in the following way:

[0024] The system obtains the vehicle speed, traffic flow, and road time occupancy rate within the temporary emergency lane control section, and determines the emergency lane congestion index of the temporary emergency lane control section according to a first preset algorithm; wherein, the first preset algorithm is:

The vehicle-road cooperative control section includes a mainline control section and an emergency lane temporary control section arranged in parallel. The vehicle-road cooperative control section is equipped with vehicle-road cooperative equipment. The vehicle-road cooperative equipment includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the temporary traffic control method for emergency lanes on highways as described above.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] This invention provides a method and system for controlling temporary traffic in emergency lanes on highways. Based on real-time data in a vehicle-road cooperative environment, this invention aims to provide a method for controlling temporary traffic in emergency lanes on highways in order to increase the traffic capacity of existing highways by increasing the number of traffic lanes. This invention utilizes vehicle-road cooperative equipment to collect real-time traffic and vehicle parameters of open emergency lanes on highways. Through real-time vehicle-road interaction within the cooperative environment, it obtains the mainline congestion index of the current mainline controlled section. When the current mainline controlled section is continuously congested, it identifies the nearest temporary emergency lane controlled section ahead of and to the current mainline controlled section. This temporary emergency lane controlled section is designated as the target controlled section. If both of the following conditions are met—no vehicles are parked within the target controlled section and no traffic accidents have occurred within it—the lane cooperative control strategy is implemented, and the target controlled section is opened to guide vehicles on the mainline controlled section to temporarily utilize it. If neither of these conditions is met, the lane cooperative control strategy is not implemented, and the current state is maintained. This application can alleviate congestion on mainline sections and maximize highway capacity by implementing the lane cooperative control strategy to enable temporary use of emergency lanes.

[0047] Please see the appendix Figure 1-2 This invention provides a method for controlling temporary traffic in emergency lanes on highways, comprising the following steps:

[0048] S1, obtain the mainline congestion index of the current mainline controlled road segment, and determine whether the mainline congestion index is greater than the preset threshold of the mainline; wherein, the method of obtaining the mainline congestion index is a mature technical means of the prior art. In a preferred embodiment, the mainline congestion index can be obtained in the following way:

[0049] The following algorithm is used to obtain the vehicle speed, traffic flow, and road time occupancy rate within the current mainline controlled section.

[0050]

[0051] in, For the location of Traffic congestion index corresponding to the time period; For the location of Road time occupancy rate at any given moment; For the location of Traffic flow at any given moment; For the location of The running speed at any given time. The parameters of the formula can be obtained using existing technologies, all of which are mature technologies and will not be elaborated upon here.

[0052] S2, when the mainline congestion index is greater than the mainline preset threshold, detect whether the current mainline controlled section is in a state of continuous congestion. It should be noted that, to avoid opening emergency lanes due to short-term traffic congestion, the system continuously determines whether the current mainline controlled section is in a state of continuous congestion. This continuous determination can be performed using the second preset algorithm described later. Alternatively, in other embodiments, a cumulative duration for which the mainline congestion index is greater than the mainline preset threshold can be set; if the cumulative duration exceeds the threshold, it is determined to be a state of continuous congestion.

[0053] S3, when the current mainline control section is in a state of continuous congestion, obtain the emergency lane temporary control section located ahead of and closest to the current mainline control section, and use the emergency lane temporary control section as the target control section; that is, when the current mainline control section is in a state of continuous congestion, the emergency lane temporary control section located ahead of and closest to the current mainline control section can be obtained. Those skilled in the art will understand that the target control section is located ahead of the current lane's direction of travel, so as to prepare measures in advance. In addition, by obtaining the position of the current mainline control section, for example by determining the distance difference between the position of the current mainline control section and the emergency lane temporary control section, the emergency lane temporary control section closest to the current mainline control section can be matched, thereby quickly determining the target control section.

[0054] S4, determine whether there are vehicles parked in the target controlled road section and whether a traffic accident has occurred in the target controlled road section; it should be noted that the absence of vehicles parked in the target controlled road section and the absence of a traffic accident in the target controlled road section will affect the temporary use of the emergency lane. Therefore, it is necessary to determine whether both conditions are met at the same time in order to determine whether the conditions for implementing the lane cooperative control strategy are met.

[0055] S51, when both of the following conditions are met: no vehicles are parked in the target controlled section and no traffic accidents have occurred in the target controlled section, the lane coordination control strategy is implemented and the target controlled section is opened to guide vehicles located on the mainline controlled section to temporarily use the target controlled section; in other words, when no vehicles are parked and no traffic accidents have occurred in the target controlled section, the conditions for implementing the lane coordination control strategy are met. At this time, the lane coordination control strategy is implemented and the target controlled section is opened to guide vehicles located on the mainline controlled section to temporarily use the target controlled section, thereby maximizing the mainline traffic capacity of the expressway.

[0056] S52. If neither of the following conditions is met: no vehicles are parked within the target controlled road segment, or no traffic accidents have occurred within the target controlled road segment, the lane cooperative control strategy will not be executed, and the current state will be maintained. In other words, if vehicles are parked or a traffic accident has occurred within the target controlled road segment, or both are present, it is determined that the conditions for executing the lane cooperative control strategy are not met. In this case, the lane cooperative control strategy will not be executed, and the current control state will be maintained.

[0057] S3, obtain the congestion index of the emergency lane of the target controlled road section, and determine whether the congestion index of the emergency lane is less than the preset threshold of the emergency lane.

[0058] In a preferred embodiment of the present invention, the step S51 is followed by the following step:

[0059] S511, After opening the target controlled road section, continuously detect whether a traffic accident occurs on the target controlled road section; it is understood that after opening the target controlled road section, the road section may become congested or may remain unobstructed. Therefore, this embodiment continuously detects whether a traffic accident occurs on the target controlled road section in order to avoid opening the emergency lane due to short-term traffic congestion and to achieve the rational use of the emergency lane.

[0060] S512, after the target controlled road section is opened, when a traffic accident occurs on the target controlled road section, the location of the traffic accident within the target controlled road section is obtained;

[0061] S513, continue to open the road section from the accident location to the end of the target control section, while closing the road section from the accident location to the start of the target control section.

[0062] In this embodiment, after the target controlled road segment is opened, it continuously monitors whether a traffic accident occurs on the target controlled road segment. If a traffic accident occurs on the target controlled road segment after it is opened, the location of the accident within the target controlled road segment is obtained. This location can be obtained through vehicle-to-infrastructure (V2I) devices installed on the controlled road segment (e.g., camera captures or a roadside terminal QF-VX1000). Those skilled in the art will understand that the section between the accident location and the end point of the target controlled road segment is unobstructed; therefore, this section from the accident location to the end point of the target controlled road segment can remain open, thus fully utilizing the emergency lane. It is understood that closing the section between the accident location and the start point of the target controlled road segment due to a traffic accident reduces traffic congestion caused by emergency lane conflicts or traffic accidents, maximizing the highway's capacity.

[0063] In another preferred embodiment, step S513 is followed by the following step:

[0064] S514, determine the distance between the accident location and the end point of the target controlled road section;

[0065] S515, determine the estimated smooth traffic duration from the accident location to the end of the target controlled road section according to a preset algorithm, and send the estimated smooth traffic duration and the end of the target controlled road section to the vehicle terminal traveling between the accident location and the end of the target controlled road section for the vehicle owner's reference.

[0066] In this embodiment, the estimated smooth traffic duration between the accident location and the end of the target controlled road section is determined according to a preset algorithm (e.g., t=s / v, where v is the set average speed and s is the distance between the accident location and the end of the target controlled road section). The estimated smooth traffic duration and the end of the target controlled road section are then sent to the vehicle terminal traveling between the accident location and the end of the target controlled road section for the driver's reference. Upon receiving the estimated smooth traffic duration and the end of the target controlled road section, the driver of the vehicle traveling on the target controlled road section improves the user experience and practicality.

[0067] In a preferred embodiment, step S511 is followed by the following step:

[0068] S5111, after the target controlled road section is opened, if no traffic accident occurs on the target controlled road section, the congestion index of the emergency lane of the target controlled road section is continuously monitored;

[0069] S5112, when the congestion index of the emergency lane is greater than a preset threshold, guide vehicles located in the target control section to leave the target control section and close the target control section.

[0070] It is important to note that in this embodiment, after the target controlled road segment is opened, if no traffic accidents occur on the target controlled road segment, the emergency lane congestion index of the target controlled road segment is continuously monitored and judged to obtain the congestion status of the target controlled road segment in real time, thereby making full use of the target controlled road segment. Specifically, when the emergency lane congestion index is greater than a preset threshold, it indicates that the target controlled road segment has become congested (i.e., exceeded the preset threshold) after a period of time after being opened. At this time, it is necessary to control the target controlled road segment, guide vehicles located in the target controlled road segment to leave the target controlled road segment, and close the target controlled road segment to avoid further congestion.

[0071] Furthermore, in another embodiment, after guiding vehicles located within the target controlled road segment to leave the target controlled road segment, it is understood that as the guidance time extends, the congestion index on the target controlled road segment will gradually decrease. When the congestion index decreases to a preset value (which can be set by those skilled in the art), the target controlled road segment can be reopened to make full use of the target controlled road segment.

[0072] In a preferred embodiment, the "emergency lane congestion index" in step S5111 is specifically obtained in the following manner:

[0073] S31, obtain the vehicle speed, traffic flow, and road time occupancy rate within the temporary emergency lane control section, and determine the emergency lane congestion index of the temporary emergency lane control section according to a first preset algorithm; wherein, the first preset algorithm is:

[0074]

[0075] in, For the location of Traffic congestion index corresponding to the time period; For the location of Road time occupancy rate at any given moment; For the location of Traffic flow at any given moment; For the location of The speed at which the machine runs at any given moment.

[0076] Furthermore, step S5111, "continuously detecting the emergency lane congestion index of the target controlled road section," specifically includes the following steps:

[0077] The congestion index of the emergency lane on the target controlled road section is continuously detected using a second preset algorithm; wherein the second preset algorithm is:

[0078]

[0079] in, For the location of The traffic congestion level assessment value at any given time, where 1 represents smooth traffic and 2 represents congested traffic. At the location of The traffic condition assessment value for a single instance at any given time, where 1 represents smooth traffic and 2 represents congested traffic. g The set number of tests.

[0080] Furthermore, the "emergency lane preset threshold" in step S3 is obtained in the following way:

[0081] The preset threshold for the emergency lane is determined according to a third preset algorithm; wherein the third preset algorithm is:

[0082] in, It is every 1 Traffic volume per lane ; It's capacity. That is, traffic capacity; It is the probability that the capacity is less than the observed flow. It is in the interval The traffic flow observed at the location represents the traffic flow before the speed decreases; It means The number of time intervals; This refers to traffic flow reaching The number of time intervals when each congestion is considered individually. =1; Congestion interval The set of values. The third preset algorithm can quickly determine the preset threshold for the emergency lane. It should be noted that the preset threshold for the emergency lane can be set to a dynamically changing value or a fixed value; those skilled in the art can set it as needed. In other embodiments, the preset threshold for the emergency lane can also be determined in other ways, such as directly setting the preset threshold for the emergency lane to a fixed value.

[0083] Furthermore, step S1 is followed by step S11, where if the mainline congestion index is less than or equal to the mainline preset threshold, the process returns to step S1. When the mainline congestion index is less than or equal to the mainline preset threshold, meaning the mainline segment is not congested, the process can return to continue acquiring the mainline congestion index of the currently controlled mainline segment for continuous monitoring.

[0084] This invention also provides a temporary traffic control system for emergency lanes on highways, including at least one vehicle-road cooperative control section (which may be one or more, and is typically located in a section other than a bridge or tunnel). The vehicle-road cooperative control section includes a mainline control section and an emergency lane temporary control section arranged in parallel. The vehicle-road cooperative control section is equipped with vehicle-road cooperative equipment, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the temporary traffic control method for emergency lanes on highways as described above. The vehicle-road cooperative equipment mentioned above can be a roadside terminal QF-VX1000, used to achieve reliable high-speed data communication between the roadside and vehicles, as well as between the roadside and pedestrians. It adopts a unified hardware platform, allowing for customized configurations of high, medium, and low-end options to meet the needs of different customers and scenarios. It supports communication technologies such as LTE-V2X, 4G / 5G, and WIFI, possesses CM-level positioning accuracy, and can be equipped with a wide range of V2X application scenarios to achieve information synchronization between vehicles and the road. It has built-in intelligent traffic management algorithms, capable of broadcasting road map data, road events, and traffic information, enabling applications such as speed guidance, road hazard warnings, and road anomaly alerts. It can provide support for vehicle-road cooperative applications for assisted driving and advanced autonomous driving. This type of equipment can construct a highway vehicle-road cooperative environment, which is a mature technology in this field and will not be elaborated upon here.

[0085] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
