Before explaining the method for determining traffic participation information provided in the embodiment of the present application in detail, an implementation environment provided in the embodiment of the present application is introduced.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an implementation environment in accordance with an example embodiment. The implementation environment may include a detection device 101, a server 102, and a terminal 103. Wherein the server 102 establishes a communication connection, typically a wireless connection, with the detection device 101 and the terminal 103, respectively.

The detection device 101 may include a camera for capturing images of the traffic participants and a processor for processing the images of the traffic participants, acquiring traffic participation information of the traffic participants, and then sending the traffic participation information of the traffic participants to the server 102.

The server 102 is configured to receive traffic participation information of traffic participants sent by the detection device, filter the traffic participation information, determine traffic participation information to be processed, and send the determined traffic participation information to be processed to the terminal 103.

The server 102 may be a server, a server cluster composed of a plurality of servers, or a cloud computing service center.

The terminal 103 is configured to process traffic participation information to be processed, and determine a collision probability between traffic participants, so that a countermeasure can be taken when a potential safety hazard exists. Typically, the terminal 103 is a terminal of a traffic participant.

The terminal 103 may be any electronic product capable of performing human-Computer interaction with a user through one or more modes such as a keyboard, a touch pad, a touch screen, a remote controller, voice interaction or handwriting equipment, for example, a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a pocket PC (pocket PC), a tablet Computer, a smart car machine, and the like.

It should be understood by those skilled in the art that the above-mentioned detection device 101, server 102 and terminal 103 are only examples, and other existing or future detection devices, servers or terminals may be suitable for the present application and are included within the scope of the present application and are incorporated herein by reference.

After the implementation environment provided by the embodiment of the present application is introduced, a detailed explanation is next given to a method for determining traffic participation information provided by the embodiment of the present application.

Fig. 2 is a flowchart illustrating a method for determining traffic participation information, which is applied to a server in the implementation environment shown in fig. 1 according to an exemplary embodiment. Referring to fig. 2, the method may include the following steps.

Step 201: and acquiring traffic participation information of the traffic participants detected in the first time period, wherein the traffic participation information is used for indicating at least one of attributes and states of the corresponding traffic participants.

It should be noted that the first duration may be set by a user according to an actual requirement, or may be set by a default of the server, which is not limited in this embodiment of the application. For example, the first duration may be 10 minutes.

As an example, the attributes of the traffic participant may include the type of the traffic participant, the shooting time point. The state of the traffic participant may include information of the driving state of the traffic participant, and may further include a driving speed, a driving direction, and the like of the traffic participant. The driving state of the traffic participant may include a stationary state or a moving state.

That is, the traffic participation information may include at least one of the type of the traffic participant, the photographing time point, the information of the driving state, the driving direction, and the driving speed.

The shooting time point is the time point when the detection equipment shoots the traffic participants through the camera device, and the shooting time point corresponds to the traffic participation information.

The types of traffic participants may include, but are not limited to, people, vehicles, and traffic signs, among others. For example, the traffic signs may include traffic lights, speed-limiting signs, road signs, and the like.

Further, the vehicle may also include a functional vehicle and a general vehicle. For example, an ambulance, a fire engine, a police car, and the like belong to the functional vehicles, and other vehicles belong to the general vehicles.

Illustratively, referring to fig. 3, fig. 3 is a schematic illustration of an image of a traffic participant, shown according to an exemplary embodiment. The figure includes 4 traffic participants, which are traffic participant a, traffic participant B, traffic participant C, and traffic participant D. The detection device can determine the type of each traffic participant by image recognition of the 4 captured images of the traffic participants. By analyzing the multi-frame images of any traffic participant, the information of the driving state of the traffic participant, the driving direction of the traffic participant, the driving speed of the traffic participant and the like can be determined.

It should be noted that the traffic participation information may further include a license plate number of the vehicle, an age of the driver, a violation condition of the driver, and the like, which is not limited in the embodiment of the present application.

In implementation, the obtaining of the traffic participation information of the traffic participant detected within the first duration may include the following two possible implementations:

the first implementation mode comprises the following steps: and receiving the traffic participation information of the traffic participants sent by the detection equipment in real time, thereby acquiring the traffic participation information of the traffic participants detected in the first time period.

That is, the detection device transmits the detected traffic participation information to the server every time the traffic participation information of the traffic participant is detected, and accordingly, the server receives the traffic participation information. And until the first time length is reached, the server acquires the traffic participation information of the traffic participants in the first time length.

The second implementation mode comprises the following steps: the server stores traffic participation information of the traffic participants in advance, and can directly acquire the traffic participation information of the traffic participants detected in the first time period.

That is, the server may store traffic participation information of the traffic participant in advance, and may determine the traffic participation information of the traffic participant within the first time period stored in the server according to the shooting time point included in the traffic participation information, thereby acquiring the traffic participation information of the traffic participant detected within the first time period.

It should be noted that, in the first duration, the server may obtain the traffic participation information of one or more traffic participants, and the same traffic participant may include one or more traffic participation information.

Step 202: and determining an information description sequence corresponding to the acquired traffic participation information, wherein the information description sequence is used for describing information characteristics of the corresponding traffic participation information in multiple dimensions.

In some embodiments, the plurality of dimensions may include road right, real-time, driving status, driving direction, driving speed, and the like.

The right of way refers to the right of the traffic participant, and is the right of the traffic participant to drive the road traffic on the road according to the traffic law in a certain time and space. For example, the road right of the traffic participant may be determined according to the type of the traffic participant, such as if the functional vehicle, the normal vehicle, the person and the traffic sign are ranked according to the height of the road right, the ranking result is the traffic sign, the person, the functional vehicle and the normal vehicle.

As an example, the real-time property may be described by a time difference between the shooting time point of the traffic participant and the target time point, and the larger the time difference is, the lower the real-time property of the traffic participation information is indicated, and the smaller the time difference is, the higher the real-time property of the traffic participation information is indicated. The target time point may be the sum of the shooting time point of the first traffic participation information acquired within the first time period and the first time period.

As an example, the information description sequence may include at least one of a road weight description value, deviation indication information, a first characteristic parameter, a second characteristic parameter, and a third characteristic parameter.

Wherein, the road right description value is used for indicating the road right of the traffic participant.

The deviation indicating information is used for indicating the real-time performance of the traffic participation information, and the deviation indicating information is inversely related to the real-time performance.

The first characteristic parameter may be used to indicate whether the traffic participation information includes information about the driving state of the traffic participant, and if the traffic participation information includes the information about the driving state of the traffic participant, the first characteristic parameter is 1, and if the traffic participation information does not include the information about the driving state of the traffic participant, the first characteristic parameter is 0.

The second characteristic parameter may be used to indicate whether the traffic participation information includes the driving speed of the traffic participant, and if the traffic participation information includes the driving speed of the traffic participant, the second characteristic parameter is 1, and if the traffic participation information does not include the driving speed of the traffic participant, the second characteristic parameter is 0.

The third characteristic parameter may be used to indicate whether the traffic participation information includes the driving direction of the traffic participant, and if the traffic participation information includes the driving direction of the traffic participant, the third characteristic parameter is 1, and if the traffic participation information does not include the driving direction of the traffic participant, the third characteristic parameter is 0.

In implementation, determining the information description sequence corresponding to the acquired traffic participation information may include the following implementation manners:

the first implementation mode comprises the following steps: after the traffic participation information of the traffic participants in the first duration is acquired, an information description sequence corresponding to each acquired traffic participation information is respectively determined.

That is to say, the traffic participation information of all the traffic participants in the first time duration is acquired, and then the information description sequence corresponding to the traffic participation information of each traffic participant is determined respectively.

In some embodiments, assuming that x represents a traffic participant, the information description sequence for that traffic participant may be represented as x-1x0x1.. xn. Wherein n is a positive integer greater than or equal to 1. x-1 may represent the information characteristic of the traffic participation information in the road right dimension, i.e. the road right description value. x0 may represent the information characteristic of the traffic participation information in the real-time dimension, i.e., the deviation indication information. x1-xn can represent information characteristics of the traffic participation information in different state dimensions, x1 can be a first characteristic parameter, x2 can be a second characteristic parameter, x3 can be a third characteristic parameter, and xn can be an nth characteristic parameter.

In implementation, the determining of the information description sequence of the traffic participation information mainly includes determining a road right description value, deviation indication information, a first characteristic parameter, a second characteristic parameter, a third characteristic parameter, and the like.

As an example, the server may store a correspondence between the road right description value and the type of the traffic participant in advance, so that in the process of determining the information description sequence of the traffic participant, the corresponding road right description value may be determined according to the type of the traffic participant in the traffic participant information. For example, x-1 takes the value of 1, which 1 corresponds to the right of way for a human being.

As an example, the deviation indication information may be derived from a time difference between the photographing time point and the target time point in the traffic participation information. For example, the shooting time points are 10: 10, target time points 11: 00, it can be determined that the deviation indication information is 50, i.e., x0 is 50.

As an example, x1 indicates whether the traffic participation information includes information of the driving state of the traffic participant, if so, x1 takes a value of 1, otherwise, x1 takes a value of 0. x2 indicates whether the traffic participation information includes the driving direction of the traffic participant, if so, x2 takes a value of 1, otherwise, x2 takes a value of 0. x3 indicates whether the traffic participation information includes the driving speed of the traffic participant, if so, x3 takes a value of 1, otherwise, x3 takes a value of 0.

The second implementation mode comprises the following steps: the first duration may include M second durations, and each time the traffic participation information of the traffic participants in the second duration is acquired, the information description sequence corresponding to the acquired traffic participation information in the second duration is determined, and for the traffic participation information in each second duration, the information description sequence corresponding to the acquired traffic participation information may be obtained by performing the above-described operations.

Wherein, M is an integer greater than or equal to 1, that is, the second time length is less than or equal to the first time length. M is the ratio of the first duration to the second duration. For example, assuming that the first time period is 1 hour and the second time period is 6 minutes, M is 10.

It should be noted that the second time period may be set by the user according to actual needs, or may be set by default by the server.

That is to say, in this implementation manner, every time the traffic participation information of the traffic participant within the second time period is acquired, the information description sequence corresponding to the traffic participation information within the second time period is determined according to the acquired traffic participation information of the traffic participant within the second time period. According to the implementation mode, after the traffic participation information in the Mth second time length is obtained and the information description sequence corresponding to the traffic participation information in the Mth second time length is determined according to the obtained traffic participation information, the server obtains the information description sequence of the traffic participation information in the first time length.

It should be noted that, according to the traffic participation information of the traffic participants in each second duration, an implementation method for determining the information description sequence corresponding to the traffic participation information in each second duration is the same as the method for determining the information description sequence in the first implementation manner, and details are not repeated here in the embodiments of the present application.

The third implementation mode comprises the following steps: and determining an information description sequence of the traffic participation information every time the traffic participation information of one traffic participant is acquired, and further determining an information description sequence corresponding to the acquired traffic participation information.

That is to say, in this implementation manner, it may be determined that the information description sequence corresponding to each piece of traffic participation information is determined after a plurality of pieces of traffic participation information are acquired, but the information description sequence corresponding to each piece of traffic participation information is determined every time the traffic participation information of one traffic participant is acquired, then the traffic participation information of the next traffic participant is acquired, the information description sequence of the acquired next piece of traffic participation information is determined continuously, and so on, the information description sequence corresponding to the acquired traffic participation information may be determined.

It should be noted that, an implementation method for determining the information description sequence corresponding to the traffic participation information in the second duration according to the acquired traffic participation information of the traffic participants in the second duration is the same as the method for determining the information description sequence in the first implementation manner, and details are not repeated here.

Step 203: and determining the traffic participation information to be processed from the traffic participation information of the traffic participants detected in the first time period according to the determined information description sequence.

That is to say, the acquired traffic participation information of the traffic participants in the first time period is not all determined to be the traffic participation information to be processed, but the traffic participation information to be processed is determined according to the corresponding information description sequence.

In a possible implementation manner, the first duration may include M second durations, and determining a specific implementation of the to-be-processed traffic participation information from the traffic participation information of the traffic participants detected in the first duration according to the determined information description sequence may include the following steps:

(1) and sequencing the information description sequences corresponding to the traffic participation information of the traffic participants detected in each second time length to obtain a first sequencing result corresponding to each second time length.

That is, referring to fig. 4, after the information description sequence corresponding to the traffic participation information in the first time period is determined, the information description sequence in each second time period may be sorted. That is, the first ordering result of the information description sequence corresponding to the plurality of traffic participation information in each second time period may be determined respectively.

In implementation, for any one of the M second durations, after the information description sequences corresponding to all the traffic participation information in the any one second duration are determined, all the information description sequences are sorted, so that a first sorting result corresponding to the any one second duration can be obtained. After the above operation is performed for each second duration, a first sorting result corresponding to each second duration can be obtained.

In some embodiments, if the information description sequence includes a road weight description value. The specific implementation of sorting the information description sequence corresponding to the traffic participation information of the traffic participant detected in each second duration may include:

for any one of the M second time periods, in response to that the road weight description value in the first information description sequence in any one of the second time periods is greater than the road weight description value in the second information description sequence, arranging the first information description sequence before the second information description sequence, where the first information description sequence and the second information description sequence are any two different information description sequences in any one of the second time periods.

And in response to the road weight description value in the first information description sequence being smaller than the road weight description value in the second information description sequence, arranging the first information description sequence after the second information description sequence.

That is, if the information description sequence includes the road right description value, for any second duration in the M second durations, the information description sequence in any second duration may be sorted according to the road right description value of the information description sequence in any second duration. For any two information description sequences in any second duration, the information description sequence with the large road weight description value can be arranged before the information description sequence with the small road weight description value.

As an example, for any two information description sequences in any second duration, the any two information description sequences may be referred to as a first information description sequence and a second information description sequence for convenience of description. For a first information description sequence and a second information description sequence, obtaining a road right description value of the first information description sequence and a road right description value of the second information description sequence, if the road right description value of the first information description sequence is greater than the road right description value of the second information description sequence, indicating that the road right of a traffic participant corresponding to the first information description sequence is higher than the road right of a traffic participant corresponding to the second information description sequence, and arranging the first information description sequence before the second information description sequence; if the road right description value of the first information description sequence is smaller than the road right description value of the second information description sequence, it indicates that the road right of the traffic participant corresponding to the first information description sequence is lower than the road right of the traffic participant corresponding to the second information description sequence, and the first information description sequence may be arranged behind the second information description sequence. For each of the M second durations, the information description sequence in each second duration may be sorted in the above manner.

For example, assuming that the first information description sequence is identified as a, the second information description sequence is identified as B, the road right description value of a is 10, and the road right description value of B is 15 in the second time period, it may be determined that the road right description value of a is smaller than the road right description value of B, that is, the road right of the traffic participant corresponding to a is lower than the road right of the traffic participant corresponding to B, and B may be arranged before a, that is, the second information description sequence is arranged before the first information description sequence.

In other embodiments, if the information description sequence includes the road right description value and the deviation indication information, the deviation indication information is used for indicating the real-time performance of the corresponding traffic participation information, and the deviation indication information is inversely related to the real-time performance. The specific implementation of sorting the information description sequence corresponding to the traffic participation information of the traffic participant detected in each second duration may include:

for any second time length in the M second time lengths, under the condition that the road weight description values in the first information description sequence and the second information description sequence in any second time length are equal, in response to that deviation indication information in the first information description sequence is smaller than deviation indication information in the second information description sequence, arranging the first information description sequence before the second information description sequence, wherein the first information description sequence and the second information description sequence are any two different information description sequences in any second time length.

The first information description sequence is arranged after the second information description sequence in response to the deviation indication information in the first information description sequence being greater than the deviation indication information in the second information description sequence.

That is, if the information description sequence includes the road right description value and the deviation indication information, for any second duration in the M second durations, the information description sequence in any second duration may be sorted according to the road right description value and the deviation indication information of the information description sequence in any second duration. For any two information description sequences in any second time length, under the condition that the road weight description values of any two information description sequences are equal, deviation indication information of any two information description sequences can be obtained, and the information description sequences with small deviation indication information can be arranged before the information description sequences with large deviation indication information because the deviation indication information is in negative correlation with real-time property.

As an example, for any two information description sequences in any second duration, the any two information description sequences may be referred to as a first information description sequence and a second information description sequence for convenience of description. For the first information description sequence and the second information description sequence, the road right description value of the first information description sequence and the road right description value of the second information description sequence are obtained, and if the road right description value of the first information description sequence is equal to the road right description value of the second information description sequence, the deviation indication information of the first information description sequence and the deviation indication information of the second information description sequence can be obtained respectively. If the deviation indication information of the first information description sequence is greater than that of the second information description sequence, which indicates that the real-time performance of the first information description sequence is lower than that of the second information description sequence, the first information description sequence may be arranged behind the second information description sequence; if the deviation indication information of the first information description sequence is smaller than that of the second information description sequence, which indicates that the real-time property of the first information description sequence is higher than that of the second information description sequence, the first information description sequence may be arranged before the second information description sequence. For each of the M second durations, the information description sequence in each second duration may be sorted in the above manner.

For example, assuming that the first information description sequence is identified as a, the second information description sequence is identified as B, the road weight description values of a and B are both 20, the deviation indication information of a is 10, and the deviation indication information of B is 18, it may be determined that the deviation indication information of a is smaller than the deviation indication information of B, that is, the real-time property of a is higher than the real-time property of B, and it may be determined that a is arranged before B, that is, the first information description sequence is arranged before the second information description sequence.

In other embodiments, if the information description sequence includes the road right description value, the deviation indication information and the state parameter, the deviation indication information is used for indicating the real-time performance of the corresponding traffic participation information. Wherein the state parameter may include at least one of the first characteristic parameter, the second characteristic parameter, and the third characteristic parameter. The specific implementation of sorting the information description sequence corresponding to the traffic participation information of the traffic participant detected in each second duration may include:

for any second time length in the M second time lengths, responding to the fact that the road weight description values in the first information description sequence and the second information description sequence in any second time length are equal, and the deviation indication information in the first information description sequence and the second information description sequence is the same, obtaining statistical information in the first information description sequence and the second information description sequence, wherein the statistical information is obtained through weighted summation, and the first information description sequence and the second information description sequence are any two different information description sequences in any second time length.

In response to the statistical information in the first information description sequence being greater than the statistical information in the second information description sequence, the first information description sequence is arranged before the second information description sequence.

The first information description sequence is arranged after the second information description sequence in response to the statistical information in the first information description sequence being less than the statistical information in the second information description sequence.

Wherein, the statistical information can be obtained by weighting and summing the state parameters. For example, if the state parameter includes a plurality of parameters, the weight of each parameter may be preset, and then the plurality of parameters are weighted and summed to obtain the statistical information. If the state parameter includes one parameter, the state parameter may be determined as statistical information, or a product of the state parameter and a weight corresponding to the state parameter may be determined as statistical information.

As an example, the statistical information of the information description sequence may be determined by the following formula (1).

Wherein W represents statistical information, x_kDenotes a parameter, w_kDenotes x_kK represents the number of the parameter in the information description sequence, and n represents the number of the parameters included in the state parameter.

That is, if the information description sequence includes the road right description value, the deviation indication information and the state parameter, for any second duration in the M second durations, the information description sequence in the second duration may be sorted according to the road right description value, the deviation indication information and the state parameter of the information description sequence in any second duration. For any two information description sequences in any second duration, under the condition that the road weight description values of any two information description sequences are equal and the deviation indication information of any two information description sequences is the same, state parameters of any two information description sequences can be obtained, and the state parameters are weighted and summed to obtain statistical information. The information description sequence with large statistical information may be arranged before the information description sequence with small statistical information.

As an example, for any two information description sequences in any second duration, the any two information description sequences may be referred to as a first information description sequence and a second information description sequence for convenience of description. For the first information description sequence and the second information description sequence, the road weight description value and the deviation indication information of the first information description sequence are acquired, and the road weight description value and the deviation indication information of the second information description sequence are acquired, if the road weight description value of the first information description sequence is equal to the road weight description value of the second information description sequence, and the deviation indication information of the first information description sequence is the same as the deviation indication information of the second information description sequence, the statistical information of the first information description sequence and the statistical information of the second information description sequence can be acquired respectively. If the statistical information of the first information description sequence is greater than that of the second information description sequence, it is indicated that the traffic participation information corresponding to the first information description sequence is more important than the traffic participation information corresponding to the second information description sequence, and the first information description sequence may be arranged before the second information description sequence; if the statistical information of the first information description sequence is smaller than that of the second information description sequence, it is indicated that the traffic participation information corresponding to the second information description sequence is more important than the traffic participation information corresponding to the first information description sequence, and the first information description sequence may be arranged behind the second information description sequence. For each of the M second durations, the information description sequence in each second duration may be sorted in the above manner.

For example, assuming that the first information description sequence is identified as a, the second information description sequence is identified as B, the road right description values of a and B are both 20, the deviation indication information of a and B is both 18, the statistical information of a is 1, the statistical information of B is 0, it may be determined that the statistical information of a is greater than that of B, that is, the traffic participation information corresponding to a is more important than that corresponding to B, and it may be determined that a is arranged before B, that is, the first information description sequence is arranged before the second information description sequence.

(2) And determining a target value of traffic participation information from the traffic participation information of the traffic participants detected in the first time length based on the first sequencing result corresponding to each second time length to obtain the traffic participation information to be processed, wherein the target value refers to the number of the traffic participation information which can be processed under the condition of allowing the specified delay threshold to be delayed.

The target value may be calculated according to the delay threshold and the information processing time, for example, the delay threshold may be divided by the information processing time to obtain the target value. The information processing time length refers to the time length for processing single traffic participation information.

It should be noted that the delay threshold may be preset by a user, or may be set by a default of the terminal, which is not limited in this embodiment of the application. For example, the delay threshold may be 1000 ms.

That is, referring to fig. 4, after the information description sequence in each second time period is sorted, the to-be-processed traffic participation information may be acquired from the traffic participation information in the first time period.

In implementation, the determining, based on the first sorting result corresponding to each second duration, a target number of pieces of traffic participation information from the traffic participation information of the traffic participants detected in the first duration, and the specific implementation of obtaining the traffic participation information to be processed may include: and determining the number of extracted information according to the specified delay threshold, the M and the information processing time, wherein the information processing time refers to the time for processing single traffic participation information, and acquiring the information extraction number of information description sequences from the first sequencing result corresponding to each second time to obtain N information description sequences, wherein N is the product of the M and the information extraction number.

And determining the traffic participation information corresponding to the N information description sequences as the target numerical value of the traffic participation information in the traffic participation information of the traffic participants detected in the first time period.

That is, it is necessary to determine the number of information extractions, that is, the number of pieces of traffic participation information that need to be acquired from each second time period, first according to the specified delay threshold, M, and the information processing time period. As an example, the information extraction number may be obtained by dividing the delay threshold by the information processing time length and M. For example, assuming that the specified delay threshold is 1000ms, M is 10, and the information processing time period is 10ms, it can be determined that the number of information extractions is 10.

In an implementation, after the number of extracted information is determined, a number of information description sequences may be obtained from the first sorting result of each second duration, and for the first duration, a total number N of information description sequences may be obtained, where N is a product of M and the number of extracted information. For example, assuming that the number of information extractions is 10, for each second duration, the first 10 information description sequences in the first ordering result may be obtained, and assuming that there are 10 second durations, a total of 100 information description sequences may be obtained.

In another possible implementation manner, determining the traffic participation information to be processed from the traffic participation information of the traffic participants detected in the first time period according to the determined information description sequence may further include one of the following implementation manners:

in implementation, the number of information extractions is first determined according to a specified delay threshold, M, and an information processing duration, which is a duration for processing a single piece of traffic participation information. And for any one of the M second time durations, storing the information description sequence every time one information description sequence is received in the any one second time duration. And after the information extraction number of information description sequences are stored, sequencing the information extraction number of information description sequences, and then sequencing the determined information description sequence and the sequenced information extraction number of information description sequences and deleting the information description sequence ranked at the last in any second time period when determining the information description sequence of the traffic participation information. Therefore, for each second duration, only the information extraction number of information description sequences are reserved all the time, and the information extraction number of information description sequences can be directly obtained. By adopting the above manner for each second time length, the information extraction number of the information description sequences of each second time length can be determined, and then N information description sequences are obtained, wherein N is the product of M and the information extraction number. And then determining the traffic participation information corresponding to the N information description sequences as the traffic participation information to be processed.

Illustratively, assuming that the specified delay threshold is 1000ms, M is 10, and the information processing time period is 10ms, it can be determined that the number of information extractions is 10. Assuming that M is 5, it can be determined that the number of information extractions is 2, that is, 2 information description sequences are determined from each second duration. For any second duration, after the information description sequence of the first traffic participation information is determined, the information description sequence of the first traffic participation information is stored, after the information description sequence of the second traffic participation information is determined, the information description sequence of the second traffic participation information is continuously stored, after the information description sequence of the third traffic participation information is determined, the three information description sequences are ranked, and the ranking mode refers to the above embodiment. And then deleting the information description sequence arranged in the third, continuously storing the information description sequences arranged in the first two digits, continuously determining the information description sequence of the next traffic participation information, sequencing the currently determined information description sequence and the two stored information description sequences, continuously deleting the information description sequence arranged in the third, and so on to obtain two information description sequences, wherein the two information description sequences are the 2 information description sequences determined in the second time length.

Therefore, the information description sequence which does not meet the requirement is continuously deleted, the storage space of the server can be saved, and the storage burden of the server is further lightened.

In implementation, after the N information description sequences are obtained, the traffic participation information corresponding to the N information description sequences may be obtained, and the traffic participation information corresponding to the N information description sequences is determined as the target numerical value traffic participation information, so that the traffic participation information to be processed is obtained.

It should be noted that the above description can implement the technical solutions of the present application. The processing of the traffic participation information to be processed by the terminal side is briefly described next.

The server can send the acquired to-be-processed traffic participation information to the terminal, and can also send the pre-stored road information to the terminal. Wherein the road information includes at least one of surface viscosity, camber, visibility, and road type.

As an example, if the same traffic participant in the traffic participant information received by the terminal includes multiple pieces of traffic participation information, the multiple pieces of traffic participation information of the same traffic participant may be sorted, and then the traffic participation information ranked first is selected as the traffic participation information of the traffic participant, and specific implementation of the sorting may be referred to above, and is not repeated here.

In implementation, in the process of determining the collision strength between any two traffic participants, the terminal may substitute the driving speed, the driving direction, the type of the traffic participant and the road information of the two traffic participants into the gravitational field theory model, the spring potential energy model and the doppler effect model, and calculate the collision strength between the two traffic participants.

In one case, if any two traffic participants for calculating the collision strength include a vehicle or a person in a stationary state, the driving speeds, the driving directions, the types of the traffic participants, and the road information of the two traffic participants can be substituted into the gravity field theory model to calculate the collision strength.

In another case, if any two traffic participants for calculating the collision strength include traffic signs, the traveling speeds, the traveling directions, the types of the traffic participants and the road information of the two traffic participants can be substituted into the spring potential energy model to calculate the collision strength.

In addition to the above two cases, when any two traffic participants calculate the collision strength in other cases, the driving speeds, the driving directions, the types of the two traffic participants and the road information may be substituted into the doppler effect model to calculate the collision strength.

It should be noted that, if the traffic participant is a vehicle, the traffic participation information of the traffic participant may further include a vehicle type of the vehicle, and thus, if any two traffic participants for calculating the collision strength include the vehicle, the vehicle type of the vehicle may also be substituted into the gravitational field theory model, the spring potential energy model, or the doppler effect model for calculation.

In implementation, after determining the collision strength between the traffic participants, the collision strength can be divided by the standard collision strength, and the collision probability can be obtained.

It should be noted that the standard collision strength may be set by a user according to a road condition, or may be set by a default of a terminal, which is not limited in this embodiment of the present application.

As an example, after determining the collision probability of the traffic participant, the collision probability may be displayed in a matrix form. See the matrix below, where the value of the element in the ith row and jth column represents the collision probability that traffic participant j brings traffic participant i.

For example, row 1, column 2, element 0.65 indicates that the collision probability of participant 2 to participant 1 is 0.75, row 2, column 3, element 0.75 indicates that the collision probability of participant 3 to participant 2 is 0.75, row 3, column 4, element 0.75 indicates that the collision probability of participant 4 to participant 3 is 0.75, row 4, column 5, element 0.75 indicates that participant 5 to participant 4 is 0.75, and the other elements in the matrix are similar in meaning.

In the embodiment of the application, traffic participation information of traffic participants detected in a first duration is obtained, and the traffic participation information is used for indicating at least one of attributes and states of the corresponding traffic participants, and then an information description sequence corresponding to the obtained traffic participation information is determined, and the information description sequence can be used for describing information characteristics of the corresponding traffic participation information in multiple dimensions. Therefore, according to the determined information description sequence, the traffic participation information to be processed can be determined from the traffic participation information of the traffic participants detected in the first time period, that is, the traffic participation information of all the traffic participants in the first time period is not determined as the traffic participation information to be processed, so that the information amount of the traffic participation information to be processed is reduced, and the burden of information transmission and information processing is reduced.
