[0002] Traffic control refers to comprehensive management measures taken for road network facilities to maintain traffic efficiency and safety and to respond to emergencies. In existing technologies, traffic control largely relies on manual experience or static rules, which are insufficiently aligned with actual road network operating conditions, demand structure, and facility constraints. This makes it difficult to measure traffic efficiency, safety, and operational impact in a timely and accurate manner, limiting the precision and effectiveness of control measures and severely hindering the improvement of traffic efficiency, operational safety, and operational revenue. Summary of the Invention

[0005] A second aspect of this disclosure provides a device for determining control measures based on road network infrastructure profiling, comprising: The control trigger module is used to respond to the trigger control command, determine the target facility corresponding to the location information in the control command; and determine the set of facilities to be controlled corresponding to the target facility based on the preset road network facility profile knowledge base. The initial executable control measure set determination module is used to obtain the facility status parameters of the target facility and the set of facilities to be controlled within a preset time period; and to determine the initial executable control measure set corresponding to the facility status parameters of the set of facilities to be controlled based on the road network facility profile knowledge base.

Detailed Implementation
[0011] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0012] It should be noted that, unless otherwise stated, the technical or scientific terms used in this disclosure shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains.
[0013] This disclosure proposes a method for determining road control measures based on road network infrastructure profiling. For example... Figure 1 As shown in the figure, the method for determining road control measures based on road network infrastructure profiling in this disclosure may include the following steps: In step S11, in response to triggering a control command, the target facility corresponding to the location information in the control command is determined; and the set of facilities to be controlled corresponding to the target facility is determined based on a preset road network facility profile knowledge base.
[0014] In step S12, the facility status parameters of the target facility and the set of facilities to be managed within a preset time period are obtained; the initial set of executable management measures corresponding to the facility status parameters of the set of facilities to be managed is determined based on the road network facility profile knowledge base.
[0015] In step S13, preset constraints are obtained, and the best evaluation result among the preset constraints is selected from the initial set of executable control measures as the target control measure; the preset constraints include operational constraints and management constraints.
[0016] For example, the conditions for triggering a control command can be that at least one of the following events occurs at the corresponding facility: speed / occupancy / queueing exceeds the corresponding threshold, related event is reported, or there is a sudden surge in demand. The facility where the control command is triggered is the target facility. After the control command is triggered, based on the target facility, a set of facilities to be controlled that affect the traffic flow of that target facility is determined. The target facility and its corresponding set of facilities to be controlled can be retrieved from a pre-built road network facility profile knowledge base.
[0017] The road network facility profiling knowledge base is constructed according to the granularity of road network facilities. Each road network target facility corresponds to a functional constraint profile. The functional constraint profile includes functional description parameters, operational constraint parameters, management constraint parameters, candidate measures and triggering conditions, cold start seed measures and priorities. The cold start seeds include strategies when various parameters are unknown during the initial startup.
[0018] After identifying the target facility, a set of facilities to be managed corresponding to the target facility can be selected from the road network facility profile knowledge base. Based on operational and management constraints, the optimal management measures for the set of facilities to be managed can then be determined.
[0019] In some embodiments, the road network facility profile knowledge base can be constructed as follows: a road network facility profile knowledge base is pre-constructed; wherein, the road network facility profile knowledge base includes a functional constraint profile of each target facility; the functional constraint profile includes a first mapping relationship and a second mapping relationship; the first mapping relationship refers to the mapping relationship between the target facility and the corresponding facility to be managed; the second mapping relationship refers to the mapping relationship between the facility status parameters corresponding to the target facility, the facility status parameters corresponding to the facility to be managed, and the set of executable control measures.
[0020] The first mapping relationship is constructed as follows: Obtain the OD set carried by the target facility; find facilities in the facility set whose OD set is equivalent to that carried by the target facility, and use these facilities as the initial set of facilities to be managed; for any initial facility to be managed, calculate the management score of the initial facility to be managed based on the traffic flow overlap parameter and traffic flow diversion parameter between the initial facility to be managed and the target facility; sort the initial facilities to be managed from high to low based on their management scores, and determine the top... The initial set of facilities to be managed is the target facility's set of facilities to be managed. The value is an integer greater than or equal to 1. The second mapping relationship is constructed in the following way: obtain the control measures of each facility to be controlled, and construct a set of candidate control measures; perform simulation evaluation based on the facility status parameters of the target facility and each candidate control facility, and take the candidate control measures that meet the preset constraints as the set of executable control measures; associate the target facility, the facility status parameters of each facility to be controlled and the corresponding set of executable control measures to obtain the second mapping relationship.
[0021] For example, target facilities include mainline sections, ramps, interchanges, toll / gantry structures, service areas, bridges, tunnels, and other road network transportation facilities. For a given OD (Origin-Destination), each transportation facility undertakes a different traffic flow transport function; some are core carrying units, while others are regulating and serving units. Different transportation facilities constitute competition or cooperation in fulfilling the given OD demand. Here, OD represents the path trajectory from the origin to the destination in the road network topology, and this path trajectory includes multiple different types of transportation facilities.
[0022] The target facility's OD set refers to all ODs passing through the target facility. This OD set can be obtained from the corresponding road network topology in the road network facility profile knowledge base. The target facility's supporting role for each OD in terms of accessibility, passability, and substitutability collectively constitutes the functional definition of the target facility. Based on the multiple optional paths between ODs and the multidimensional coupling relationships between the facilities contained in those paths, we can quantify the functional value and criticality of the facility for a specific OD or OD set. Furthermore, while ensuring the road network functionality corresponding to key OD sets, we can identify the complementary, substitutive, and competitive relationships between different facilities.
[0023] For example, the functional value of facilities to the OD set can be categorized into three types: traversal, dependence, and substitutability. Crossing OD Subset : Characterizes the OD that must pass through the facility in all optimal or acceptable generalized cost paths; Dependency on OD subset This characterizes the relative increase in the generalized cost of the optimal acceptable path for an OD (Original Development Path) exceeding a threshold once the facility's capacity is weakened or becomes unavailable. OD; Alternative OD subsets There is an acceptable alternative route that does not involve this facility, and the relative cost increase does not exceed a threshold. OD.
[0024] Among them, the generalized cost can be composed of a weighted average of factors such as time, toll fees, and reliability; Set thresholds for business operations; Characterization facilities.
[0025] The functional value of a facility depends on the importance of OD (Original Design Site), and this disclosure introduces a weighting factor. To define the importance of OD. The definition considers the OD's traffic (or demand share) and business-side weights (strategic importance, freight share, time period importance, etc.): (1) in, Characterizes the initial weighting coefficients corresponding to OD. Parameters are set by the user.
[0026] Let the set of OD be To normalize formula (1), we get: (2) Defining the importance weight of any OD Based on this, this disclosure defines facilities from several dimensions, including coverage, dependence intensity, irreplaceability, and substitutability. Functional attributes: Coverage representation The importance of service OD: (3) Dependency strength characterizes the importance of OD to this Degree of dependence: (4) Exclusivity / non-substitutability rate characterization after this And OD that is difficult to replace: (5) in is the numerical stability constant.
[0027] Substitutability characterization and this Equivalent facilities' capacity to absorb the OD (Original Demand) they undertake: (6) in, Defined The equivalent set of facilities, Facilities in the equivalent facility set The remaining capacity share (available margin under the same caliber). Consistency / reliability weights are applied (considering vehicle type / traffic restrictions / toll consistency, etc.).
[0028] In summary, four functional attributes corresponding to facilities have been defined, and facilities can be further divided into three types of functional tags: Core bearing unit: meets the requirements High value High value Low value, and A high value indicates that the unit carries a large number of irreplaceable critical ODs and is the "backbone that cannot be damaged by mistake"; Typical load-bearing unit: The value is moderate. value, Value and Value in the middle; Adjustment unit: Low value or High value, and Low or medium value.
[0029] like Figure 2 As shown, let For high-volume OD, For secondary ODs with relatively small flow rates, the definition of facility function labels can be used to determine: It belongs to the core carrying unit. It carries a large amount of weight. Main passage and All are high. It is also high and has high substitutability. Low, and once weakened, will significantly increase the generalized cost of key OD.
[0030] It belongs to a general bearing unit and mainly serves For a portion of the traffic, there are acceptable alternative paths and a certain margin, exhibiting a moderate level of performance. and and medium .
[0031] It belongs to the adjustment unit. Its main functions are shaping and sharing, with a relatively small weight. It flows, and has good substitutability. Low, high, Low, suitable for prioritizing speed-limiting / guidance and other regulatory measures.
[0032] The above functional labels describe the importance of the facilities corresponding to each OD in the OD set. Based on the importance, non-core units and units with operability are selected as the initial set of facilities to be managed. For any initial facility to be managed, the management score of the initial facility to be managed is calculated based on the traffic flow overlap parameter and traffic flow diversion parameter between the initial facility to be managed and the target facility.
[0033] Traffic overlap parameters are calculated in the following way: (7) in, The threshold for determining the degree of overlap; Characterizing facilities to be controlled The set of ODs that can be directly affected.
[0034] Traffic flow can be diverted using the following parameters: (8) in, To and A set of equivalent facilities that undertake the same / similar origin-destination (OD); for facilities Let its time-varying margin be denoted as Its consistency / reliability weight is .
[0035] Control rating: (9) Select from highest to lowest score, satisfying rules such as mutual exclusion and minimum interval, and take at most [number of items]. One group entered the facility to be controlled, among which It is an integer greater than or equal to 1; , This is a weighting coefficient, which can be set according to the actual situation.
[0036] Let the target facility be Pre-set up to a maximum number from its collection of facilities to be managed. One facility to be managed is designated as... The system will acquire control measures for each facility to be controlled and construct a set of candidate control measures. Next, simulation evaluation will be conducted based on the facility status parameters of the target facility and each candidate control facility. Candidate control measures that meet preset constraints will be selected as the set of executable control measures.
[0037] set up Target facility A corresponding executable control measure combination strategy is defined, along with the strategy overview: (10) in This refers to a combination of different measures (such as traffic restriction / interception, toll station access restriction / closure, traffic diversion, and parallel / serial combinations of opposite lanes). The adjustment level of the control parameters corresponding to the control measures (taken from the allowable range of each measure). (discrete values); The timing encoding of the measures (parallel / serial relationship, start time, duration, etc.).
[0038] Set a uniform evaluation time window for measuring operational effectiveness. (e.g., 30 / 45 / 60 minutes), and an overview of the initial state of the simulation experiment: (11) In essence, it defines the abstract working conditions and external conditions corresponding to this simulation test (peak / off-peak, event / non-event, vehicle-to-cargo ratio range, weather category, toll rate / traffic restriction level, etc.). for It includes a collection of facilities to be managed.
[0039] Computer simulations are used to predict the effectiveness of each candidate control measure combination under specific traffic conditions, and feasible combinations are selected. The state parameters of the target facility over a set time period can be used as the initial conditions for the simulation model. Next, the corresponding candidate control measure combinations are input into the simulation model as intervention strategies, and evaluation time window parameters are set (e.g., simulation duration is 45 minutes into the future). The dynamic evolution of traffic flow is simulated, and relevant performance indicators are output, such as travel time, queue length, traffic safety risk proxy index, key origin-destination (OD) demand satisfaction, and toll revenue changes. Finally, the simulation output results are compared with preset operational constraints. Only candidate combinations whose simulation results fully meet the constraints are marked as executable control measure combinations.
[0040] To store the combination of executable control measures selected through simulation to the database, a mapping relationship between the target facility, facility status parameters, and the set of executable control measures can be constructed during storage, and the data can be persistently stored in the road network facility profile knowledge base.
[0041] During the simulation, meso / micro traffic simulation or an equivalent rapid estimator can be used, ensuring consistency with actual measurements (speed, flow rate, queueing, gantry tolling flow). Calibration during the simulation is based on real historical data to calibrate key parameters (basic flow-speed relationship, car-following / lane-changing parameters, saturation flow rate, vehicle composition, entrance / exit allocation, etc.); historical event replays are used to evaluate queue growth rate, speed profile, and obstacle clearance. The response undergoes cross-calibration until the error is within acceptable limits. The baseline reproduction error (velocity / queue / capacity) for uninterrupted scenarios should be below a set threshold (e.g., ...). Perform a validity check.
[0042] The simulation output should include both operational and management dimensions.
[0043] The output results of the running dimension include: This indicates the predicted average speed (or quantile speed) between the facility and its upstream location within the assessment window. This indicates the predicted peak and length of the facility's queues; This indicates the change in the total travel time of the system; This indicates a change in safety indicators (such as sudden deceleration / collision).
[0044] The output results of the operational dimension include: weighted satisfaction of key ODs. and revenue / expense estimates The calculation methods are as follows: Key OD weighted satisfaction : First, the satisfaction level of OD is assessed using the time-achievement metric, i.e., within the assessment time window. Within this framework, satisfaction is defined based on the proportion of arrival times not exceeding a baseline threshold. (12) in, This refers to the historical percentile threshold or the service commitment threshold.
[0045] The satisfaction levels of each OD are assigned according to their weights. polymerization: (13) The higher the value, the better. A lower limit is usually set in the acceptability determination, such as... .
[0046] Revenue / Expense Estimation : Using gantry / toll station billing flow as the metric, in the simulation system, the total revenue of the strategy scenario and the baseline scenario within the evaluation window is compared: (14) Positive values indicate a decrease in revenue ("loss"); negative values indicate an increase in revenue. An upper limit can be set in the acceptability assessment: .
[0047] For each combination of control measures (including parameters and timing), if the following hard constraints are met simultaneously: , , and When indicators meet set thresholds; hard operational constraints: , If certain indicators meet the set thresholds, the operation is marked as executable; otherwise, it is marked as inexecutable and removed. The set of executable control operations is then marked as... .
[0048] (15) To support rapid screening and online optimization in practical applications, this disclosure establishes a unified effect evaluation mapping model when determining the acceptability of the aforementioned strategy and state profiles through simulation experiments. . This is used to characterize the running and operational evaluation results of candidate strategies under a given state and evaluation time window, and is exemplified as follows: (16) in, This is a general overview of the situation. For an overview of the strategy, For the assessment of the time window. , , and For operational indicators; and For operational metrics.
[0049] The above describes the construction process of the aforementioned knowledge base for road network infrastructure profiling.
[0050] The corresponding road network infrastructure profiling knowledge base also includes a cost function for control measures, so as to track and evaluate the corresponding control measures after their implementation. Specifically, the cost function for control measures is constructed in the following way: a cost function for control measures is constructed with facility status parameters and combinations of control measures as independent variables, wherein the evaluation result parameters of the cost function for control measures include key OD weighted satisfaction parameters, operational constraint parameters, and benefit parameters; based on the cost function for control measures, the evaluation results of each control measure are generated. This application embodiment does not limit the specific form of the above cost function; those skilled in the art can set it according to actual conditions.
[0051] In some embodiments, determining the set of facilities to be managed corresponding to the target facility based on a preset road network facility profile knowledge base includes: determining the functional constraint profile corresponding to the target facility from the preset road network facility profile knowledge base; and searching for the set of facilities to be managed corresponding to the target facility based on the functional constraint profile corresponding to the target facility.
[0052] For example, after the target facility is determined, the corresponding functional constraint profile can be found in the preset road network facility profile knowledge base based on the identification and other information of the target facility. As mentioned above, the functional constraint profile includes a first mapping relationship and a second mapping relationship. The set of facilities to be controlled is determined according to the corresponding first mapping relationship, and the set of executable control measures is found according to the second mapping relationship.
[0053] In some embodiments, determining the initial set of executable control facilities also requires satisfying relevant constraints, including: obtaining a set of all executable control measures corresponding to the facility status parameters of the facility to be controlled from the road network facility profile knowledge base; and filtering control measures that satisfy preset constraints from the set of all executable control measures to obtain the initial set of executable control measures. The preset constraints include operational constraints and management constraints; the preset constraints also include at least one of the following: consistency constraints, traffic margin constraints, and interval and smoothing constraints; wherein the operational constraints indicate that the corresponding control measures meet preset traffic operation boundary thresholds; and the management constraints indicate that the corresponding control measures meet preset revenue boundary thresholds.
[0054] Correspondingly, in practical applications, the initial set of executable control measures... The selection of the best evaluation result among the preset constraints as the target control measure also includes: ranking the evaluation results of each initial executable control measure and selecting the one with the largest evaluation result. These control measures are identified as control measures to be optimized. The value is an integer greater than or equal to 1. For any control measure to be optimized, the control parameters in the control measure to be optimized are adjusted according to the preset data change rules to obtain the evaluation results corresponding to the multiple control parameters of the control measure to be optimized. Based on the evaluation results corresponding to the multiple control parameters, the control parameter with the best evaluation result is determined as the target control parameter.
[0055] For example, for the initial set of executable control measures Any initial executable control measure in Construct the cost function of control measures as follows: (17) Among them, the above Various items are mapped by a unified effect evaluation model. Given; weights satisfy .
[0056] Based on cost function In the initial set of executable control measures We will construct an optimization method to find the most effective target control measures.
[0057] (18) Typically, the control parameters corresponding to the determined executable control measures are default values or optimized parameters obtained from historical data. In this case, in order to further adapt to the current road conditions, in some embodiments, the control measures in the above combination of control measures can be further optimized and fine-tuned locally.
[0058] In some implementations, for any control measure to be optimized, the control parameters in the control measure to be optimized are adjusted according to preset data change rules to obtain the evaluation results corresponding to multiple control parameters of the control measure to be optimized; based on the evaluation results corresponding to multiple control parameters, the control parameter with the best evaluation result is determined as the target control parameter.
[0059] For example, for each control parameter in the combination of control measures to be optimized, its domain (minimum / maximum), precision (adjustment step size), and constraints (such as a speed limit not lower than 30 km / h) are analyzed, and a sequence of candidate parameter values is generated based on preset data change rules. The preset data change rules can be a binary search strategy, a grid search, or a set of random numbers, etc.
[0060] For each candidate parameter value, a simulation is performed, taking the current road condition and control parameter configuration as input, and outputting the parameter evaluation results for the next 15-30 minutes.
[0061] For example, after implementing target control measures, various operational parameters of those measures, such as traffic flow speed and queue length, can be continuously acquired within an evaluation window. If these operational parameters do not meet the predicted parameters, the target control measures can be switched to a pre-set conservative plan.
[0062] The method disclosed herein, in response to a triggered control command, determines the target facility corresponding to the location information in the control command. Based on a road network facility profile knowledge base, it identifies a set of facilities to be controlled corresponding to the target facility, thereby limiting control measures to this set and reducing uncertainty caused by network-wide searches and trial-and-error. Furthermore, based on the facility status parameters of the target facility and the facilities to be controlled within a preset time period, it quickly determines a matching set of initial executable control measures, avoiding strategies that are unimplementable or incompatible with facility capabilities. Finally, under the combined constraints of operational and management constraints, it selects the best initial executable control measure set as the target control measure. Therefore, it enables rapid generation, implementation, risk control, and traceable control outputs, improving control consistency and reducing overall operation and maintenance costs.
[0063] Corresponding to the above implementation method for determining road control measures based on road network infrastructure profiling, this disclosure also provides a device for determining control measures based on road network infrastructure profiling, such as...
