Description

Technical Field

[0001] The present invention relates to the field of computer systems based on specific computing models, and in particular to a smart traffic scheduling optimization method based on cloud-edge collaborative computing. Background Art

[0002] Cloud-edge collaborative computing is a computing model that combines cloud computing and edge computing. It aims to optimize data processing and transmission through collaborative work to meet the needs of diverse scenarios. Cloud-edge collaborative computing achieves a distributed computing model by shifting computing power from the centralized cloud to edge nodes close to data sources, thereby optimizing data processing capabilities. Cloud-edge collaborative computing is the fusion of cloud computing and edge computing, aiming to achieve efficient data processing and transmission. Cloud computing typically involves storing data and applications on servers in remote data centers and providing services over the network, while edge computing pushes data processing closer to edge devices, such as sensors and embedded systems, to the data source. This collaborative model not only improves system performance and reliability but also meets complex and diverse application requirements. For example, cloud-edge collaborative computing can be used to achieve targeted optimization of urban smart transportation scheduling.

[0003] For example, the Chinese invention patent application publication CN118711373A proposes a smart traffic scheduling optimization system based on cloud-edge collaborative computing, which includes an edge monitoring module and a cloud analysis module. The system connects multiple edge processing devices through a cloud management center network, and each edge processing device is equipped with a camera device and an edge monitoring module. After acquiring real-time traffic images, the edge monitoring module generates a feature data set through CNN algorithm model analysis and transmits it to the cloud management center through the network. The cloud management center is equipped with a cloud analysis module to record the receiving time point and calculate the standard signal transmission time, clarify the measurement standard of the data transmission quality of each edge processing device, judge the degree of collaboration between the cloud and the edge, and efficiently manage the cloud-edge data interaction with high accuracy. The collaborative analysis unit calculates and generates a traffic flow index, and generates a corresponding management report after comparing the traffic flow index threshold. The cloud-edge collaborative scheduling optimization effect is good.

[0004] For example, Chinese invention patent publication CN118522141 A proposes a method and system for intelligent traffic monitoring, identification, and control. The solution includes setting up sensors for information collection, dividing regions into remote areas and non-remote areas; continuously monitoring the remote areas to form a basic data set; online data collection for non-remote areas to form a driving prediction data set; estimating remote areas in combination with the basic data set to form form-estimated data for remote areas, and updating the basic data set as vehicles pass through; correcting other driving times that require passing through corresponding remote areas; and completing a traffic scheduling plan based on the final vehicle driving time, so that all clients using the corresponding software can display the route with the optimal time. The solution uses the on-board GPS and pre-entered information on the vehicle's driving environment for online correction and analysis, thereby completing intelligent traffic scheduling for a combination of remote and non-remote areas.

[0005] It can be seen from this that the various technical solutions involving urban traffic scheduling in the above-mentioned existing technologies either only focus on the speed and efficiency of cloud-edge collaborative computing itself, or belong to the optimization of traffic routes without applying cloud-edge collaborative computing. They are unable to predict the traffic conditions of each "cell" of urban traffic, that is, each traffic section, in the future. Naturally, it is impossible to optimize the corresponding intelligent traffic scheduling of each traffic section based on the prediction results. For example, due to the relatively limited number of lanes in each traffic section and the different congestion status of various types of vehicles in different time intervals of the same traffic section, it is difficult to accurately predict the congestion status of various types of vehicles in the future time interval of each traffic section. It is impossible to flexibly adjust the traffic direction of each lane in the future time interval of the traffic section to meet the different traffic needs of different types of vehicles in the future time interval, resulting in the traffic scheduling of each traffic section in the existing technology being rigid and fixed, and it is difficult to make full use of limited lane resources. Summary of the Invention

[0006] In order to solve the technical problems in the prior art, the present invention provides a smart traffic scheduling optimization method based on cloud-edge collaborative computing, which can introduce the congestion status of various types of vehicles on a set road section at the same time in the past days, whether left turns are allowed in the front and rear sections of the set road section, and the section length, single lane width and number of surrounding sections of the set road section as basic data. It uses a smart traffic prediction model with targeted structural design to intelligently predict the congestion status of various types of vehicles on the set road section within a fixed time period on the same day, and dynamically revise the number of left-turn lanes and electric bicycle borrowing mode of the set road section based on the intelligent prediction results, so as to make full use of the relatively limited lane resources of the set road section and improve the travel speed and efficiency of various vehicles in each future time interval of the set road section.

[0007] According to the present invention, a smart traffic scheduling optimization method based on cloud-edge collaborative computing is provided, the method comprising:

[0008] Using edge monitoring equipment located above the front end of a set road section to monitor each set of past data corresponding to each past day, the single set of past data corresponding to each past day includes the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of the set road section within a fixed time interval on that day, the set road section including a set number of lanes;

[0011] A remote cloud analysis device is used to use an intelligent traffic prediction model to intelligently predict the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of the set road section within the fixed time interval on that day based on the set number, the length of the fixed time interval, the respective copies of past data corresponding to the past days, and the various road section parameters of the set road section;

[0012] The sum of the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on that day and the total number of straight-going vehicles at the front end of the set road section within the fixed time interval on that day is used as the predicted total number of vehicles; the percentage of the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on that day to the predicted total number of vehicles is calculated as a reference left-turn percentage; and when the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on that day exceeds a set number threshold, a left-turn lane is configured for the set road section within the fixed time interval on that day;

[0013] When the ratio of the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on a given day to the total number of through vehicles at the front end of the set road section within a fixed time interval on a given day exceeds a preset ratio limit, the electric bicycles passing at the front end of the set road section within a fixed time interval on a given day are allowed to use the leftmost through lane of the set road section;

[0014] When the total number of left-turn vehicles at the front end of a set road section within a fixed time interval on a given day exceeds a set number threshold, allocating a left-turn lane for the set road section within the fixed time interval on the given day includes: allocating a matching number of left-turn lanes for the set road section within the fixed time interval on the given day based on a reference left-turn percentage;

[0015] Wherein, configuring a matching number of left-turn lanes for a set road section within a fixed time interval of the day based on the reference left-turn percentage includes: the number of left-turn lanes configured for the set road section within the fixed time interval of the day is monotonically positively correlated with the reference left-turn percentage;

[0016] Wherein, within the set road section, the left-turn lane, the straight lane and the electric bicycle lane are arranged in order from left to right;

[0017] The cloud analysis device is connected to each edge monitoring device corresponding to each road section via a wireless network.

[0018] Compared with the prior art, the present invention has at least the following five main inventive concepts:

[0019] Inventive Concept A: Based on the total number of left-turning vehicles, through-going vehicles, and electric bicycles passing through a set road section at fixed time intervals on previous days and various road section parameters of the set road section, the total number of left-turning vehicles, through-going vehicles, and electric bicycles passing through the set road section at a fixed time interval on the same day are intelligently predicted, thereby completing an intelligent prediction of the total number of left-turning vehicles, through-going vehicles, and electric bicycles passing through the set road section at a future time interval based on the past simultaneous traffic conditions of the set road section and various road section parameters inherent to the set road section, providing valuable reference data for optimizing intelligent traffic scheduling of the set road section in future time intervals;

[0020] Inventive Concept B: In addition to the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing through the set road section at fixed time intervals on each day in the past, and various road section parameters of the set road section, the basic data used for intelligent prediction also includes the number of lanes in the set road section and the length of the fixed time interval. At the same time, the various road section parameters of the set road section include the section length of the set road section, the width of a single lane, the number of surrounding road sections, the left-turn enable flag of the preceding road section, and the left-turn enable flag of the following road section, thereby ensuring the sufficiency and comprehensiveness of the basic data and laying the foundation for the reliability and stability of the intelligent prediction results;

[0021] Inventive Concept C: Customizing the structure of a smart traffic prediction model for intelligent prediction, specifically by performing multiple training operations on a BP neural network to obtain a BP neural network after the multiple training operations, and outputting the BP neural network after the multiple training operations as the smart traffic prediction model, wherein the number of training operations performed by the BP neural network is proportional to the length of a fixed time interval, thereby establishing smart traffic prediction models with different structures for time intervals of different lengths, further ensuring the reliability and stability of the smart prediction results;

[0022] Inventive Concept D: In each training operation performed on the BP neural network, the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on a certain historical day are used as outputs of the BP neural network, and the set number, the length of the fixed time interval, the past data corresponding to each of the past days corresponding to the certain historical day, and various road section parameters of the set road section are used as inputs of the BP neural network to complete this training operation, thereby ensuring the training effect of each training operation of the BP neural network;

[0023] Inventive concept E: Based on the prediction results, a corresponding intelligent traffic scheduling optimization strategy is established to ensure the travel speed and efficiency of various vehicles on the set road section within the fixed time period of the day, and reduce the congestion probability of the set road section. The specific optimization strategy is to calculate the percentage of the total number of left-turning vehicles at the front end of the set road section within the fixed time period of the day to the total number of passing vehicles as a reference left-turn percentage. When the predicted total number of left-turning vehicles exceeds the set number threshold, a left-turn lane is configured for the set road section within the fixed time period of the day, and a matching number of left-turn lanes are configured for the set road section within the fixed time period of the day based on the reference left-turn percentage. At the same time, when the proportion of the predicted total number of passing electric bicycles to the predicted total number of straight-moving vehicles exceeds the preset proportion limit, the passing electric bicycles at the front end of the set road section within the fixed time period of the day are allowed to borrow the leftmost straight-moving lane of the set road section.

[0030] Figure 6 Flowchart of the steps of the intelligent traffic scheduling optimization method based on cloud-edge collaborative computing according to embodiment 5 of the present invention DETAILED DESCRIPTION

[0031] like Figure 1 As shown, a technical flow chart of the intelligent traffic scheduling optimization method based on cloud-edge collaborative computing according to the present invention is given.

[0032] exist Figure 1 In the city where smart traffic scheduling optimization is performed, there are various road sections, and each road section is equipped with an edge monitoring device, for example, Figure 1 Two edge monitoring devices are given, serving two road sections respectively. At the same time, a cloud analysis device is set up on the management side. The cloud analysis device is connected to each edge monitoring device on each road section through a wireless network, thus building the hardware resources of the smart traffic scheduling optimization mechanism based on cloud-edge collaborative computing.

[0033] Specifically, in cities with optimized smart traffic dispatch, corresponding edge monitoring equipment is set above the front end of each road section, and Figure 1 In the embodiment, each edge monitoring device includes a camera mechanism, a mobile base station and a traffic light device, and may also include a counting mechanism (not shown) and a timing mechanism (not shown);

[0034] like Figure 1 As shown, the specific technical process of the present invention is as follows, wherein technical processes one and two can be selected to be executed at the edge monitoring device, and technical processes three, four, and five can be selected to be executed at the cloud analysis device:

[0035] Technical Process 1: For a specific road section within a city where intelligent traffic scheduling optimization is being implemented, the total number of left-turning vehicles, straight-going vehicles, and e-bikes passing through the road are collected within a fixed time interval on each day of the past. The road section parameters, the number of lanes on the specific road section, and the length of the fixed time interval are also obtained.

[0036] Specifically, the various section parameters of the set road section are the section length of the set road section, the width of a single lane, the number of surrounding sections, the left turn enable mark of the front section, and the left turn enable mark of the rear section;

[0037] In this way, through the full and comprehensive selection of multiple basic data, a foundation is laid for the reliability and stability of subsequent intelligent prediction results;

[0038] Technical Process 2: Customize smart traffic prediction models with different structures for time intervals of different lengths to further ensure the reliability and stability of smart prediction results;

[0039] Specifically, the structural customization of the intelligent traffic prediction model is reflected in the following aspects:

[0040] First, performing multiple training operations on the BP neural network to obtain a BP neural network after the multiple training operations are performed, and using the BP neural network after the multiple training operations as a smart traffic prediction model;

[0041] Second, the number of training operations performed by the BP neural network is proportional to the length of the fixed time interval;

[0042] Third, in each training operation performed on the BP neural network, the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on a certain historical day are used as output content of the BP neural network, and the set number, the length of the fixed time interval, the past data corresponding to each of the past days corresponding to the certain historical day, and the various road section parameters of the set road section are used as input content of the BP neural network to complete this training operation, thereby ensuring the training effect of each training operation of the BP neural network;

[0043] Technical Process 3: Using the customized smart traffic prediction model from Technical Process 1, based on the comprehensive and comprehensive data selected in Technical Process 1, the model intelligently predicts the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles on a specific road section within a fixed time period on that day.

[0044] Technical Process 4: Based on the total number of left-turning vehicles, straight-going vehicles, and electric bicycles on a set road section within a fixed time period on that day, obtained through intelligent prediction in Technical Process 3, a dynamic optimization plan is provided for intelligent traffic scheduling of each lane on the set road section within a fixed time period on that day;

[0045] Specifically, the percentage of the total number of left-turning vehicles at the front end of a set road section within a fixed time interval on that day to the total number of passing vehicles is calculated as a reference left-turn percentage. When the predicted total number of left-turning vehicles exceeds a set number threshold, a left-turn lane is configured for the set road section within the fixed time interval on that day. Furthermore, a matching number of left-turn lanes is configured for the set road section within the fixed time interval on that day based on the reference left-turn percentage.

[0046] Specifically, when the ratio of the predicted total number of passing electric bicycles to the predicted total number of through vehicles exceeds a preset ratio limit, the passing electric bicycles at the front end of a set road section within a fixed time interval on that day are allowed to use the leftmost through lane of the set road section;

[0047] In this way, the traffic needs of different vehicles can be met as much as possible under limited traffic resources.

[0048] The key points of the present invention are: full and comprehensive selection of multiple basic data including the total number of left-turning vehicles, the total number of straight-going vehicles and the total number of electric bicycles passing through the set road section in the same time period on previous days, various road section parameters of the set road section, the number of lanes of the set road section and the time length of the fixed time interval, structural customization of the intelligent traffic prediction model, construction of hardware resources for the intelligent traffic scheduling optimization mechanism based on cloud-edge collaborative computing, and dynamic adjustment of the intelligent traffic scheduling optimization strategy based on intelligent prediction results.

[0049] Below, the intelligent traffic scheduling optimization method based on cloud-edge collaborative computing of the present invention will be specifically described in the form of an embodiment.

[0050] Example 1

[0051] Figure 2 This is a flowchart of the steps of the intelligent traffic scheduling optimization method based on cloud-edge collaborative computing according to Example 1 of the present invention.

[0052] like Figure 2 As shown, the intelligent traffic scheduling optimization method based on cloud-edge collaborative computing includes the following specific steps:

[0053] Step S21: Using an edge monitoring device located above the front end of a set road section, monitor each set of past data corresponding to each past day, wherein the single set of past data corresponding to each past day includes the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of the set road section within a fixed time interval on that day, wherein the set road section includes a set number of lanes;

[0054] For example, an edge monitoring device arranged above the front end of a set road section is used to monitor each set of past data corresponding to each of the past days. The single set of past data corresponding to each of the past days includes the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of the set road section within a fixed time interval on that day. The set road section includes a set number of lanes, including: the intelligent prediction is the traffic data of various types of vehicles of the set road section within the fixed time interval from 9 a.m. to 9:30 a.m. on the day, and the each set of past data corresponding to each of the past days is the traffic data of various types of vehicles within the fixed time interval from 9 a.m. to 9:30 a.m. for the past 8 days. Since the fixed time interval from 9 a.m. to 9:30 a.m. on the day has not yet arrived, it belongs to the future time interval and needs to be processed by intelligent prediction;

[0055] Specifically, a city optimized for smart traffic scheduling includes multiple road sections, and the set road section is one of them, which has an end and a front end of the road section. All types of vehicles pass from the end of the set road section to the front end of the set road section. At the front end of the set road section, some vehicles have the need to turn left, some vehicles have the need to go straight, and there is also a need for a passage area for electric bicycles.

[0056] Step S22: capturing various parameters of the set road section, wherein the various parameters of the set road section include the length of the set road section, the width of a single lane, the number of surrounding road sections, the left turn enable flag of the preceding road section, and the left turn enable flag of the following road section;

[0057] For example, capturing various section parameters of the set road section, wherein the various section parameters of the set road section are the section length of the set road section, the width of a single lane, the number of surrounding sections, the left turn enable flag of the preceding section, and the left turn enable flag of the following section, including: when the distance from the end of the set road section to the front end of the set road section is 800 meters, the section length of the set road section is 800 meters;

[0058] Step S23: performing multiple training operations on the BP neural network to obtain a BP neural network after the multiple training operations are performed, and outputting the BP neural network after the multiple training operations as a smart traffic prediction model, wherein the number of training operations performed by the BP neural network is proportional to the length of the fixed time interval;

[0059] Specifically, a plurality of training operations are performed on the BP neural network to obtain a BP neural network after the plurality of training operations are performed, and the BP neural network after the plurality of training operations is output as the intelligent traffic prediction model, and the number of training operations performed by the BP neural network is proportional to the length of the fixed time interval, including: the length of the fixed time interval is 15 minutes, the number of training operations performed by the BP neural network is 150, the length of the fixed time interval is 30 minutes, i.e., half an hour, the number of training operations performed by the BP neural network is 300, the length of the fixed time interval is 60 minutes, i.e., 1 hour, the number of training operations performed by the BP neural network is 600, and so on;

[0060] Step S24: using a remote cloud analysis device to employ a smart traffic prediction model to intelligently predict the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of the set road section within the fixed time interval on the day based on the set number, the length of the fixed time interval, the respective copies of past data corresponding to the past days, and the various road section parameters of the set road section;

[0061] For example, a cloud analysis device disposed at a remote end is used to adopt an intelligent traffic prediction model to intelligently predict the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on that day based on the set number, the length of the fixed time interval, the respective copies of past data corresponding to the past days, and the various road section parameters of the set road section, including: the set number is the number of lanes of the set road section, for example, 10 lanes;

[0062] Step S25: The sum of the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on the day and the total number of straight-going vehicles at the front end of the set road section within the fixed time interval on the day is used as the predicted total number of vehicles; the percentage of the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on the day to the predicted total number of vehicles is calculated as a reference left-turn percentage; when the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on the day exceeds a set number threshold, a left-turn lane is configured for the set road section within the fixed time interval on the day;

[0063] For example, when the total number of left-turning vehicles at the front end of a set road section within a fixed time interval on a given day exceeds a set number threshold, configuring a left-turn lane for the set road section within the fixed time interval on that day includes: the set number threshold may be 500, and when the total number of left-turning vehicles at the front end of the set road section within the fixed time interval on that day exceeds 500, configuring a left-turn lane for the set road section within the fixed time interval on that day;

[0064] Step S26: When the ratio of the total number of electric bicycles passing at the front end of the set road section within the fixed time interval to the total number of vehicles going straight at the front end of the set road section within the fixed time interval on the day exceeds a preset ratio limit, the electric bicycles passing at the front end of the set road section within the fixed time interval on the day are allowed to use the leftmost straight lane of the set road section;

[0065] For example, when the ratio of the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on a given day to the total number of straight-going vehicles at the front end of the set road section within the fixed time interval on a given day exceeds a preset ratio limit, the electric bicycles passing at the front end of the set road section within the fixed time interval on a given day are allowed to borrow the leftmost straight-going lane of the set road section, including: Here, the electric bicycles passing are merely borrowing the lane, and the leftmost straight-going lane of the set road section is a driving area where the electric bicycles need to be clearly identified by the motor vehicle driver as being allowed to borrow the lane;

[0066] When the total number of left-turn vehicles at the front end of a set road section within a fixed time interval on a given day exceeds a set number threshold, allocating a left-turn lane for the set road section within the fixed time interval on the given day includes: allocating a matching number of left-turn lanes for the set road section within the fixed time interval on the given day based on a reference left-turn percentage;

[0067] Wherein, configuring a matching number of left-turn lanes for a set road section within a fixed time interval of the day based on the reference left-turn percentage includes: the number of left-turn lanes configured for the set road section within the fixed time interval of the day is monotonically positively correlated with the reference left-turn percentage;

[0068] Specifically, the number of left-turn lanes configured for a set road section within a fixed time interval of the day and the reference left-turn percentage are monotonically positively associated, including: when the number of lanes on the set road section is 10, when the value of the reference left-turn percentage is 20%, the number of left-turn lanes configured for the selected set road section within the fixed time interval of the day is 2; when the value of the reference left-turn percentage is 35%, the number of left-turn lanes configured for the selected set road section within the fixed time interval of the day is 3; when the value of the reference left-turn percentage is 50%, the number of left-turn lanes configured for the selected set road section within the fixed time interval of the day is 4;

[0069] In this way, considering that there are left-turn lanes in the sections ahead and behind the set road section, vehicles that have the need to turn left in the future can choose to turn left. Through the design of the above numerical correspondence, the traffic demand of the straight lanes of the set road section can be met as much as possible under the premise of ensuring the matching of the traffic demand of left-turn vehicles, thereby ensuring the traffic efficiency of the set road section;

[0070] Wherein, within the set road section, the left-turn lane, the straight lane and the electric bicycle lane are arranged in order from left to right;

[0071] The cloud analysis device is connected to each edge monitoring device corresponding to each road section via a wireless network;

[0072] wherein, edge monitoring equipment disposed above the front end of a set road section is used to monitor respective copies of past data corresponding to respective days in the past, wherein the single copy of past data corresponding to each day in the past includes the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of the set road section within a fixed time interval on that day, wherein the set road section includes a set number of lanes, and the smaller the value of the set number, the fewer the number of days in the past selected;

[0073] For example, the smaller the value of the set number is, the fewer the number of days in the past that are selected is: when the set number is 10, the number of days in the past that are selected is 8; when the set number is 8, the number of days in the past that are selected is 7; when the set number is 6, the number of days in the past that are selected is 6, and so on;

[0074] The capturing of various road section parameters of the set road section includes the road section length of the set road section, the width of a single lane, the number of surrounding road sections, the left turn enable flag of the road section ahead, and the left turn enable flag of the road section behind, including: among a set number of lanes in the set road section, the width of each lane is the same, and the length of each lane is the same, and the length of each lane is equal to the road section length of the set road section;

[0075] wherein, performing multiple training operations on the BP neural network to obtain the BP neural network after the multiple training operations are completed, and outputting the BP neural network after the multiple training operations as the intelligent traffic prediction model, wherein the number of training operations performed by the BP neural network is proportional to the time length of the fixed time interval, including: in each training operation performed on the BP neural network, using the known total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on a certain historical day as the output content of the BP neural network, using the set number, the time length of the fixed time interval, each copy of past data corresponding to each past day corresponding to the certain historical day, and each section parameter of the set road section as the input content of the BP neural network to complete this training operation;

[0076] And wherein, in each training operation performed on the BP neural network, the total number of left-turning vehicles, the total number of straight-going vehicles, and the total number of electric bicycles passing at the front end of a set road section within a fixed time interval on a certain historical day are used as the output content of the BP neural network, and the set number, the time length of the fixed time interval, the various past data corresponding to the past days corresponding to the certain historical day, and the various section parameters of the set road section are used as the input content of the BP neural network. Completing this training operation includes: the various past data corresponding to the past days corresponding to the certain historical day are the various past data corresponding to the past days before the certain historical day.
