A navigation-based road emergency passage dynamic authorization management and auxiliary decision method and system

Abstract

This invention discloses a navigation-based dynamic authorization and control method and system for emergency lanes. Existing technologies lack a purely software-based solution that combines fixed opening on holidays with temporary closure during emergencies, while maintaining emergency attributes throughout. This invention adopts a strategy of full closure on weekdays, fixed opening on holidays, and temporary closure during emergencies: During holidays, emergency lanes are open by default, indicated by a flashing green line on the navigation map; when closure is required, a temporary closure command is issued after dual verification of identity and digital signature, dynamically setting a virtual clearing buffer zone upstream of the designated section, pushing graded yielding commands only to the specified section and switching to a flashing red line; after closure, the system automatically verifies passage conditions based on navigation big data, automatically restoring the green status without manual operation or on-site sensing equipment. No markings are displayed on non-holidays. This invention is purely software-based, requiring no modification to roadside hardware, balancing traffic efficiency and emergency safety.

Description

Technical Field

[0001] This invention relates to the field of intelligent traffic management and control technology, specifically to a navigation-based method and system for dynamic authorization control and auxiliary decision-making of emergency lanes on roads. This invention is applicable not only to the dynamic authorization control of emergency lanes on highways but also to ordinary roads such as urban arterial roads and expressways, providing advance clearing and priority passage for emergency rescue vehicles such as fire trucks, ambulances, and police cars. The core of this invention lies in the method for rapid clearing and restoration of traffic flow after the emergency lane has been opened; this is only disclosed as one application scenario. Background Technology

[0002] The emergency lane on highways is a dedicated lane for emergency rescue vehicles such as police cars, fire trucks, and ambulances to perform their duties, as well as for temporary parking of other vehicles in emergency situations such as sudden breakdowns or sudden illness of drivers and passengers. It is a lifeline to ensure the passage of emergency rescue vehicles. According to traffic regulations, other vehicles are strictly prohibited from occupying it without a legal reason.

[0003] During peak travel periods such as statutory holidays, Spring Festival travel rush, and summer travel rush, traffic volume on major highways surges dramatically, easily leading to prolonged and widespread traffic congestion. Main lanes approach saturation, while emergency lanes remain largely unused, resulting in a significant waste of road resources. Currently, traffic management departments in many parts of China have piloted the temporary opening of emergency lanes during holidays, allowing private vehicles to temporarily use them during peak traffic hours. This has effectively alleviated congestion on highway main lanes, demonstrating a significant improvement in traffic flow.

[0004] However, the existing pilot operation model and similar publicly available technical solutions still have many obvious shortcomings: First, there is a lack of unified and fixed opening standards. Most opening plans rely on real-time congestion data to determine whether to open. The issuance of control instructions is delayed, and drivers cannot know the traffic rules in advance. They hesitate and look around during their journey, which fails to fully play the role of easing congestion. Second, the traffic guidance methods are too simplistic, relying solely on electronic displays along the road and on-site traffic police to convey the rules, which cannot cover all vehicles and lacks intuitive and visual traffic guidance methods. Third, the boundaries of control are vaguely defined, making it impossible to strictly distinguish between daily traffic hours and peak travel hours. This easily leads to the phenomenon of normalized opening, which seriously encroaches on emergency rescue traffic space and violates the original intention of establishing emergency lanes. Fourth, it does not take into account the sudden emergency needs of the road. The existing open mode is difficult to control and retract quickly after opening. In case of emergency such as accident rescue and medical emergency, it is impossible to clear the emergency lane quickly, which delays the emergency response. Moreover, the traditional control mode mostly relies on manual release of control, which is prone to problems such as forgetting operation and delay in unblocking. The degree of intelligent closed loop is insufficient. Fifth, it ignores the need for temporary emergency parking for vehicles, and focuses solely on comprehensive traffic control without reserving emergency parking space for disabled vehicles or drivers and passengers suffering from sudden illnesses, resulting in obvious shortcomings in practicality; Sixth, existing solutions mostly rely on roadside sensing devices and road surface monitoring hardware to complete on-site condition identification, which has high deployment costs, is difficult to modify, and is difficult to promote and implement on a large scale and quickly.

[0005] In summary, existing highway emergency lane management models generally suffer from a polarization in traffic control: either strict closure leads to resource waste, or blind opening results in the loss of emergency passage functionality. Furthermore, they suffer from drawbacks such as reliance on manual unblocking, high hardware modification costs, and weak self-healing capabilities. The industry urgently needs to develop a purely software-based intelligent navigation-side management solution that features fixed opening on holidays, temporary closure during emergencies, dual visual and auditory traffic alerts, advance interception of upstream traffic flow, multi-lane collaborative guidance, dual verification of command legitimacy, and fully automatic intelligent recovery without hardware limitations. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a navigation-based method and system for dynamic authorization control and auxiliary decision-making of emergency lanes. This system achieves a layered and precise control model, enabling fully enclosed lanes on weekdays to safeguard emergency traffic safety, fixed opening lanes on holidays to alleviate traffic congestion, and temporary closure to clear emergency lanes during emergencies. The system utilizes a fixed opening mechanism on holidays to inform drivers of traffic rules in advance. Visual cues, such as flashing green lane-level edge lines (green for passage, red for clearing), and voice prompts, provide dual visual and auditory guidance. Through two-way instructions from rescue vehicles and traffic management departments, and after dual verification using identification and digital signatures, targeted temporary closures are completed. This is combined with upstream virtual buffer zones to preemptively intercept traffic flow and multi-lane collaborative traffic management to quickly clear lanes. The entire process eliminates the need for on-site sensor monitoring hardware, relying on the existing multi-dimensional big data of the navigation platform to autonomously determine on-site traffic conditions. Temporary control is automatically lifted and the original traffic status is restored without manual intervention. Simultaneously, the emergency lane's emergency stopping function is retained at all times, comprehensively addressing both daily traffic management and emergency rescue needs.

[0007] The present invention adopts the above-mentioned intelligent hierarchical management and control technology solution, and the specific implementation process is carried out in accordance with all the contents of claims 1 to 11.

[0008] The key innovative technologies of this invention are summarized as follows: 1. A fixed-opening control mode during holidays, independent of congestion data limitations, automatically opens based solely on preset time periods, ensuring clear and unified travel rules. These preset peak control periods can be accurate to specific calendar dates and start and end hours, supporting batch import or one-click addition / reduction by traffic management departments via a cloud-based backend, and can be flexibly configured according to annual, quarterly, or specific activity cycles.

[0009] 2. A manual authorization mechanism for temporary shutdown is implemented, accepting shutdown commands only issued proactively by rescue vehicles and traffic management departments and verified through both identification and digital signature. The system will not automatically trigger a clearing operation. The identification is a unique device code for the emergency rescue terminal or traffic management terminal, and the digital signature is a traffic management-specific encrypted signature used to verify the legality and integrity of the command and prevent interference from unauthorized commands.

[0010] 3. An upstream virtual clearing buffer zone is added to dynamically calculate the safe distance and intercept traffic flow in advance, preventing new vehicles from entering during the closure and clearing period. The safe distance is calculated by combining the road section's design speed limit with the real-time average traffic speed, converting it into a safe interception distance that ensures upstream vehicles can be orderly diverted or stopped before rescue vehicles arrive (for example, approximately 3 kilometers dynamically calculated based on a vehicle speed of 80 km / h in Example 1). The specific calculation formula can be expressed as: Safe distance = Reaction distance + Braking distance + Safety margin, where the reaction distance is estimated based on real-time vehicle speed and the driver's average reaction time (e.g., 2 seconds), the braking distance is estimated based on the road adhesion coefficient and vehicle speed, and the safety margin is a fixed value (e.g., 50 meters), or it can be dynamically determined directly using empirical lookup tables.

[0011] 4. Establish a multi-lane, full-area collaborative avoidance system to achieve orderly adjustment of traffic flow in different lanes and smoothly complete the diversion of vehicles from the emergency lane; 5. A three-tiered voice broadcast system, combined with differentiated prompts and legal responsibility warnings, enhances the driver's willingness to cooperate in leaving the area. The distance thresholds for the three-tiered broadcasts can be configured as follows: Level 1 warning is triggered 5 kilometers upstream of the rescue vehicle, Level 2 mandatory warning is triggered 2 kilometers upstream, and Level 3 emergency warning is triggered 500 meters upstream. Specific values ​​can be dynamically adjusted based on the road's design speed and traffic density. The system can automatically calculate and switch broadcast levels based on the real-time location and speed of the rescue vehicle, ensuring the driver has sufficient reaction time.

[0012] 6. Innovative lane-level visual color linkage prompts: There are no special markings on non-holidays; when the road is open on holidays, the thin line on the edge flashes green; when it is temporarily closed, it flashes red. It is intuitive and easy to understand without interfering with the main visual line. 7. The emergency lane retains its legally mandated emergency stopping function at all times, meeting the temporary stopping needs of vehicle malfunctions and sudden discomfort of personnel under any control conditions; 8. The entire process adopts a pure software operating architecture, requiring no modification to the existing roadside hardware facilities of the highway, making deployment convenient and promotion cost-effective; 9. A dual verification mechanism for access command validity is implemented, which verifies the identity and digital signature of the access terminal, automatically rejects commands that fail verification and issues an alarm, ensuring that the system only responds to legitimate commands; 10. A hardware-free, fully automatic self-healing and recovery mechanism has been added. Based on multi-dimensional data such as navigation vehicle positioning, traffic flow distribution, and traffic speed, the on-site status is determined. No on-site sensing equipment or manual back-end operation is required. Traffic is automatically restored when the conditions are met, forming a closed loop of unmanned intelligent management and control throughout the entire process, and completely solving the problems of forgetting manual unsealing and lagging management.

[0013] Beneficial effects: Compared with existing traditional control technologies, this invention has the following practical advantages: 1. Balancing traffic safety and congestion management efficiency, the system maintains strict closures on weekdays to ensure emergency response, while opening regularly on holidays to efficiently divert traffic and alleviate congestion; 2. With clear and unified travel expectations, travelers can learn about the emergency lane rules in advance based on their holiday plans, reducing hesitation and indecisiveness while driving; 3. Comprehensive traffic guidance: The navigation edge lines flash green and red, accompanied by real-time voice broadcasts, which are eye-catching but not dazzling, and provide all-round reminders for drivers to adjust their driving routes; 4. Emergency clearing is precise and efficient. By relying on targeted road section control and upstream traffic interception, emergency lanes are quickly cleared, minimizing the waiting time for emergency rescue passage. 5. Adaptable to various complex road scenarios, enabling differentiated management of individual highway segments and flexibly matching traffic congestion conditions on different road sections; 6. Convenient and standardized law enforcement and control, accurately distinguishing between compliant traffic and illegal lane occupation, helping traffic management departments to complete intelligent traffic law enforcement and control; 7. Strong hardware and software compatibility; the pure software deployment mode is compatible with various mainstream navigation platforms and traffic management platforms, and the implementation threshold is low. 8. The functions are tailored to actual travel needs, and the emergency stop function is retained for a long time, fully taking into account both daily travel and emergency response scenarios. 9. The system only responds to valid commands that have undergone double verification, effectively preventing interference from illegal or erroneous commands and ensuring secure and reliable control. 10. On non-holidays, the navigation interface maintains its regular style without any additional markings to avoid visual redundancy and driver fatigue; 11. When applied to urban roads, this invention can dynamically calculate and generate a priority timing scheme for traffic lights at the intersection ahead based on the real-time location and speed of the rescue vehicle. For example, the traffic lights in the direction of the rescue vehicle's travel can be adjusted to green, while those in the opposite direction can be adjusted to red, thus achieving coordinated linkage between the navigation terminal and the signal control terminal and further improving the efficiency of rescue passage. 12. Achieve intelligent closed-loop management throughout the entire process. After the emergency response is completed, the system will automatically determine the traffic conditions and restore normal traffic order without the need for on-duty personnel. This will greatly reduce the pressure on traffic operation and maintenance management and significantly improve the timeliness and practicality of management. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the overall method flow of the present invention, covering the entire control process of fixed opening, temporary closure, and fully automatic autonomous restoration of access; Figure 2 This is a schematic diagram of the internal functional module architecture of the system of the present invention; Figure 3 This is a schematic diagram of lane-level visual rendering of the navigation map of the present invention, showing three states of the thin lines on the road edge: green flashing (open), red flashing (temporarily closed), and no markings in normal condition. Specific Implementation

[0015] Example 1: Control of Fixed Opening and Temporary Closure of Emergency Lanes during Statutory Holidays During the National Day holiday, designated sections of the G15 Shenhai Expressway automatically switched to a fixed-open emergency lane status according to the system's preset control rules. Before vehicles approach the controlled section, the navigation system broadcasts a passage prompt in advance, and at the same time, the thin line on the edge of the emergency lane on the corresponding section of the navigation map flashes green, clearly informing drivers that they can legally use the emergency lane, effectively alleviating traffic congestion on the main line.

[0016] During a holiday trip, a rear-end collision occurred on a designated section of the highway, with injured passengers requiring immediate medical assistance. The ambulance driver initiated a request to clear the emergency lane via the vehicle's onboard terminal. The system first performs dual verification of the onboard terminal's identity and digital signature. After successful verification, the clearing request is pushed to the traffic management terminal for confirmation. Once a legitimate instruction is issued, the control process is officially initiated, and the clearing zone defined in the instruction is analyzed (starting point K180+000, ending point K182+000).

[0017] After receiving the instruction, the cloud platform automatically calculates the safe passage distance upstream of the cleared section and sets up a virtual clearing buffer zone (e.g., dynamically calculates about 3 kilometers based on the current vehicle speed of 80km / h). Starting from the buffer zone, it pushes a first-level warning to leave, and simultaneously switches the thin line on the edge of the emergency lane of the corresponding section from flashing green to flashing red, warning vehicles that they are prohibited from entering and must leave immediately.

[0018] Based on the real-time travel distance of rescue vehicles, Level II mandatory departure instructions and Level III emergency passage instructions were sequentially sent to vehicles in the emergency lane. Simultaneously, the navigation system sent messages to vehicles in the middle lane: "Emergency rescue ahead, please move slightly to the left to allow space for lane changes," and to vehicles in the left fast lane: "Rescue lane ahead is under control, please maintain a steady speed and do not change lanes arbitrarily." This guided multi-lane coordination and implemented segmented, staggered traffic diversion. Utilizing the upstream buffer zone for advance interception, no new vehicles entered the clearing section, and the entire road section was cleared in a short time, ensuring ambulances could quickly reach the accident scene to carry out rescue work.

[0019] After the on-site accident is handled and all rescue vehicles have left the controlled area, the system does not require the deployment of any road surface sensing equipment, nor does it require traffic management personnel to manually issue unblocking commands. Relying on backend navigation and positioning data, lane vehicle distribution data, and road section traffic speed data, the system verifies from multiple dimensions that there are no accident vehicles, stranded vehicles, or traffic obstacles at the scene. After a short-term delay and stable monitoring to confirm that the status is stable, the system automatically lifts the temporary shutdown control, the emergency lane automatically returns to the state of flashing green edge lines, and pushes a road traffic resumption notification. Social vehicles can continue to use the lane normally, achieving unattended intelligent closed-loop control throughout the entire process.

[0020] Example 2: Minor road accidents do not require emergency clearing and control. During the same holiday travel period, minor collisions occurred on other sections of the highway. No one was injured in either party's accident; they took photos as evidence and quickly left the scene without calling for professional emergency vehicles. Because no effective temporary lane closure / clearing command was issued, the system did not initiate any lane clearance control operations. The emergency lane in that section continued to display a flashing green edge line, allowing normal traffic flow without disrupting normal traffic order.

[0021] Example 3: Practical Application of All-Time Emergency Stop Function During holidays when emergency lanes are open, if a vehicle experiences an engine failure while driving, the driver can temporarily pull into the emergency lane to repair it after activating the vehicle's hazard lights. The navigation system will identify the vehicle's stationary position and hazard light signal in real time, promptly sending avoidance warnings to vehicles within a two-kilometer radius behind, reminding them to slow down and give way. Simultaneously, the emergency stop event will be reported to the local traffic management platform. This process is unaffected by the emergency lane's open or closed status. The thin visual markings (flashing green) along the edge of the emergency lane will remain visible, but the warning information will be prioritized.

[0022] Example 4: Regular closed-loop management during off-peak travel periods During weekday, non-holiday travel periods, the system automatically determines that these are not peak control times, and the emergency lane on the navigation map has no special markings, appearing completely consistent with regular roads. The emergency lane on highways remains completely closed throughout, allowing drivers to rely on standard traffic regulations without additional visual cues, ensuring unimpeded and rapid passage for all types of emergency rescue vehicles.

[0023] Example 5: Segmented Differentiated Management of Long-Distance Highway Sections During the peak return traffic period of the Spring Festival travel rush, the degree of congestion varies significantly across different sections of long-distance highways. Traffic management departments pre-emptively divide the highways into multiple independently controlled sub-segments via a cloud-based system. Emergency lanes are only opened in a fixed mode on extremely congested sections (marked by a thin green flashing line at the edge of the corresponding section), while sections with less congestion remain unmarked. When an emergency rescue is needed on one of the open sections, only that section and its upstream buffer zone are temporarily closed and cleared (that section flashes red), while the remaining open sections remain flashing green. Navigation maps accurately distinguish the control status of different sections, resulting in greater flexibility in management. After the rescue mission is completed, the corresponding section automatically verifies the on-site status and resumes traffic autonomously, without affecting the normal traffic order of other sections.

[0024] Example 6: Priority passage control for emergency rescue ambulances on urban roads This plan is also applicable to emergency rescue scenarios on ordinary roads such as urban arterial roads and urban expressways. Since urban roads do not have fixed dedicated emergency lanes, the general standard of all vehicles slowing down and pulling over to the right to make room for other vehicles on the left is uniformly applied. There is no need to distinguish between different types of lanes, making it easy for all drivers to quickly understand and implement.

[0025] When an ambulance is on an emergency medical rescue mission, the driver initiates a lane clearance request through the vehicle's terminal. After the system completes dual verification of the driver's identity and digital signature, it designates a temporary control section based on the ambulance's real-time route and sets up a virtual clearing buffer zone upstream of the route to divert traffic in advance. The navigation system simultaneously pushes unified voice guidance, prompting vehicles along the route to smoothly slow down and pull over to the right side of the road, making way for the ambulance to pass quickly.

[0026] If traffic congestion or insufficient space prevents the ambulance from pulling over in time, the system will simultaneously coordinate with the intersection's traffic signals. Based on the real-time location and speed of the emergency vehicle, it will dynamically calculate and generate a priority timing scheme for the traffic lights at the next intersection (for example, adjusting the traffic lights in the direction the ambulance is traveling to green and those in the opposite direction to red). Priority will be given to allowing the emergency vehicle to pass through the intersection, ensuring timely rescue. Once the ambulance has completely left the controlled section, the system will immediately and autonomously assess the traffic environment, automatically lifting the temporary control measures, and restoring normal traffic flow.

[0027] Example 7: Rapid road clearing for fire trucks responding to emergency calls in urban areas When a fire breaks out in the city and fire trucks are dispatched to the scene, traffic control instructions can be issued via onboard terminals or traffic management platforms. The system will immediately provide full-area traffic guidance along the fire truck's route. Traffic is diverted in advance using upstream virtual clearing buffer zones, and right-of-way prompts are broadcast throughout the navigation system, guiding all vehicles on the road to orderly pull over to the right side of the road, thus clearing the left side of the main traffic lanes.

[0028] In situations involving rush hour congestion, heavy traffic at intersections, and situations where other vehicles cannot promptly yield or clear the way, the system coordinates with the city's traffic signal system. Based on the real-time location and speed of the rescue vehicle, it dynamically calculates and generates a priority traffic light timing scheme for the intersection ahead (for example, adjusting the traffic lights in the direction the fire truck is traveling to green and the opposite direction to red), granting the fire truck priority passage and ensuring that the rescue vehicle can pass quickly without being restricted by regular traffic lights. Once the fire truck leaves the section of road, the control is immediately lifted, and normal traffic resumes along the entire route, with only necessary on-site control remaining at the location of the emergency.

[0029] For traffic violations, the system automatically identifies the following two scenarios: first, unauthorized occupation of the emergency lane during non-authorized periods (excluding holidays and peak traffic management periods); second, unexcused lingering within authorized temporary opening periods after receiving a clearing instruction, exceeding a reasonable time (e.g., 30 seconds). Violation data includes vehicle anonymization tags, timestamps, road segment location markers, and violation type (illegal occupation / lingering), automatically uploaded to the traffic management enforcement platform in a structured data format (e.g., JSON), forming a complete enforcement loop. The reasonable time threshold can be dynamically adjusted based on road segment speed limits and real-time traffic density, rather than being mechanically determined by a fixed time.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and optimizations made within the scope of the technical solution concept of the present invention should be included within the scope of protection of the claims of the present invention.
