[0067] In this embodiment, the current position of the vehicle is obtained based on GPS positioning, and the current position of the person is obtained based on terminal positioning of the smart terminal carried by the person.

[0068] In this embodiment, the road network is obtained by counting all position points that can be positioned on the road.

[0069] In this embodiment, the track drawing refers to the combination of multiple parameters such as the position point of the object movement, the moving time at each position point, the time of reaching each position point and the time of leaving each position point.

[0070] In this embodiment, the dynamic probability is obtained according to the dynamic moving position point, the static probability refers to the time point when the position point is not occupied, and the dynamic probability, the static probability and the position intersection probability are calculated in real time during the calculation process, mainly for real-time adjustment of traffic control.

[0072] In the embodiment, the greater the position intersection probability, the greater the object density of the corresponding position, that is, the greater the need for regulation, the greater the dynamic probability, the greater the flow of the corresponding position, that is, the greater the need for control, and the greater the static probability, the smaller the flow of the corresponding position, the less the need for control.

[0073] In the embodiment, after the range is divided in three ways, the range intersection is determined, which can effectively determine the sub-range with large flow and large density as the dynamic intersection sub-range.

[0074] The sub-range with small flow and small density can also be effectively determined as the static intersection sub-range.

[0075] In the embodiment, the target range corresponding to the first division result, except for the dynamic intersection sub-range, is the first independent sub-range, and the target range corresponding to the second division result, except for the static intersection sub-range, is the second independent sub-range, wherein the first independent sub-range and the second independent sub-range can or can not have an overlapping range.

[0076] In the embodiment, the range attribute is related to the probability type and the probability value of the probability involved in the corresponding range, and the control label is obtained based on the identifier that can represent the probability type and the probability value.

[0077] In the embodiment, the label similarity analysis refers to the similarity analysis between the color and the symbol size of the identifier.

[0078] In the embodiment, the control database contains the identifier corresponding to different similarity analysis results and the control method matched with the identifier, and the control method is related to congestion and flow release, lane change, etc.

[0079] In the embodiment, the control range contains several sub-ranges, and the control method corresponding to each sub-range is related to the label identifier, and finally the corresponding control methods can be the same or different, mainly for simultaneous traffic control of a large area to improve the control efficiency.

[0080] The beneficial effects of the above technical solution are: by depicting the moving track of the target object and determining the dynamic probability, the static probability and the position intersection probability, the range is divided multiple times, and by comparing the results and analyzing the label similarity, the traffic control of the road can be effectively realized, and the control efficiency is improved.

[0081] The application provides a dynamic and static combined traffic control method, which comprises the following steps of:

[0082] planning a target range of the target network, and setting a position coordinate to the target range;

[0083] placing each current position on a coordinate matched with the target range to obtain a road network.

[0084] In this embodiment, the target range refers to a range of 10 meters on the left and right of a position 1 on a road A, and the position coordinate is set to the target range based on geographic information.

[0085] In this embodiment, the current position refers to the position of the object positioned.

[0086] The beneficial effects of the above technical solution are that the position coordinate of the target range is set, and the positioned position is matched with the set position, so that the road network is obtained, and the traffic condition of the road is reasonably analyzed, and an analysis basis is provided for subsequent traffic control.

[0087] The application provides a dynamic and static combined traffic control method, which comprises the following steps of:

[0088] acquiring a position point of the same target object at each moment;

[0089] setting a thickness mark to the corresponding position point according to the number of times of appearance of the same position point;

[0090] constructing a moving track of the same target object according to all the mark results, wherein the moving track comprises a stay time at different track points and point coordinates of different track points.

[0091] In this embodiment, the number of times of appearance of the same position point refers to the stay time of the same target object at the position point, the longer the stay time, the thicker the corresponding mark, and the shorter the stay time, the thinner the corresponding mark.

[0092] In this embodiment, the moving track is mainly constructed according to the position coordinates, and the thickness of each position coordinate point may be different.

[0093] The beneficial effects of the above technical solution are that the thickness mark is set according to the number of times of appearance of the same position point, the drawing of the track is realized, and a basis is provided for the calculation of the subsequent dynamic probability, static probability and position intersection probability.

[0094] The application provides a traffic control method combining dynamic and static, which establishes dynamic probability, static probability and position intersection probability of each position point in the target range according to all moving trajectories, comprising:

[0095] According to the moving trajectory, a statistical array of each position point in the target range is constructed, wherein the statistical array comprises non-occupied time points, occupied time points and occupied objects of the occupied time points.

[0096] According to the non-occupied time points, the static probability J0 of the corresponding position point is determined.

[0097] Meanwhile, according to the continuous occupied time points of the same occupied object to the same position point, and based on the object type-time-impact database, the dynamic impact factor J of the corresponding position point is determined.

[0098] According to the dynamic occupied time points of different occupied objects on the same position point, the first dynamic probability D1 of the corresponding position point is determined.

[0099] According to 1-J0, the second dynamic probability D2 is obtained.

[0100] According to the first dynamic probability D1 and the second dynamic probability D2, the final dynamic probability D0 is obtained.

[0101]

[0102] Wherein, max represents the maximum value symbol; max(D1, D2) represents the larger one of D1 and D2; a1 represents the weight based on the first dynamic probability D1; (1-a1) represents the weight based on the second dynamic probability D2; δ(J) represents the fine tuning function of the dynamic probability.

[0103] The number of occupied objects of the same position point at the same occupied time point is determined, and the position intersection probability W is obtained:

[0104]

[0105] Wherein, n1 represents the number of occupied objects of the same position point at the same occupied time point; n2 represents the maximum number of occupied objects of the corresponding position point at the same occupied time point.

[0106] In this embodiment, the calculation of the static probability J0 is as follows:

[0107] J0=t / t0

[0108] Wherein, t represents the cumulative time sum of the non-occupied time points; t0 represents the cumulative time sum of the non-occupied time points and the occupied time points.

[0109] In this embodiment, for example, the traffic control is updated once every 10 seconds, at which time 10 seconds is the total time, if there are 3 seconds of non-occupancy time points at the same location, at this time, the static probability is: 3 / 10.

[0110] In this embodiment, if the continuous occupancy time point for position 1 is 2, and the corresponding object type is a vehicle in a driving state, then the dynamic influence factor is obtained from the object type-time-influence database, wherein the object type-time-influence database contains different object types, continuous occupancy times, and matched dynamic influence situations to ensure the accuracy of subsequent control, and the dynamic influence factor is mainly used to determine the influence of the object on the dynamic probability in the case of moving but moving slowly, and the value is generally [0.0.1].

[0111] In this embodiment, the first dynamic probability D1 is calculated as follows:

[0112] D1=t1 / t0, wherein t1 represents a dynamic occupancy time point, and the dynamic occupancy time point can not include a continuous occupancy time point.

[0113] In this embodiment, the second dynamic probability D2=1-J0.

[0114] In this embodiment, the value range of δ(J) is [0, 0.05], and the smaller the dynamic influence factor, the smaller the value of δ(J).

[0115] In this embodiment, the dynamic probability is recalculated by combining the two ways of obtaining the dynamic probability to ensure the uniqueness of the obtained dynamic probability.

[0116] In this embodiment, the value of a1 corresponding to the peak period is 0.5, and the value corresponding to the low peak period is 0.8.

[0117] In this embodiment, the number of occupied objects refers to the occupancy of the same location at the same time, for example, the occupancy of position 1 is 3, and the maximum occupancy of this position 1 is 5, at which time it can be preliminarily determined that there is a congestion situation, which is represented by the position intersection probability.

[0118] In this embodiment, the calibration of each position point in the moving trajectory is not the same, so the statistical array of each position point can be effectively determined to facilitate the acquisition of various probabilities subsequently.

[0119] The beneficial effects of the above technical solutions are: by constructing the statistical array of each position point, and by continuously, dynamically analyzing the occupation and non-occupation of the position points at the time points, the various probabilities existing can be effectively determined, an effective basis for subsequent range division is provided, and the efficiency of subsequent traffic control is ensured.

[0120] The application provides a dynamic and static combined traffic control method, which performs first division on the target range according to the dynamic probability, and includes the following steps.

[0121] The dynamic probability of each position point in the target range is obtained, and a dynamic probability graph is constructed.

[0122] According to the dynamic probability level, each position point in the dynamic probability graph is color-labeled to obtain the same type of labeled color distribution, and the first division of the target range is realized.

[0123] In this embodiment, the dynamic probability graph refers to the fact that each position point in the graph has a matching dynamic probability.

[0124] In this embodiment, the dynamic probability level is pre-set, for example, 0-0.3 is a level, 0.31-0.5 is a level, 0.51-0.7 is a level, and 0.71-1 is a level.

[0125] The beneficial effects of the above technical solutions are: by constructing the dynamic probability graph and color-labeling each position point in the graph according to the probability level, the first division of the range can be realized, a basis for the subsequent simultaneous control of multiple sub-ranges is provided, and the control efficiency is further improved.

[0126] The application provides a dynamic and static combined traffic control method, which obtains dynamic intersection sub-ranges and static intersection sub-ranges according to the first division result and the third division result, and the second division result and the third division result, and includes the following steps.

[0127] The intersection range with the same color of the first division result and the third division result is obtained, and the dynamic intersection sub-range is obtained, and the intersection range with the same color of the second division result and the third division result is obtained, and the static intersection sub-range is obtained.

[0128] The color label corresponding to the second division result is determined according to the static probability level.

[0129] The color label corresponding to the third division result is determined according to the position intersection probability level.

[0130] In this embodiment, the setting mode of the static probability level and the position intersection probability level is similar to the setting mode of the dynamic probability level, and will not be repeated here.

[0131] In this embodiment, however, the dynamic and static probability levels are opposite when color calibration is performed, for example, as the dynamic probability level increases, the corresponding colors are white, pink, blue, and black in turn, but as the static probability level increases, the corresponding colors are black, blue, pink, and white in turn, that is, the current occupancy of the same position point to be represented should be consistent.

[0132] The beneficial effects of the above technical solution are: by intersecting the colors according to different first, second and third division results, the dynamic intersection sub-range and the static intersection sub-range can be effectively determined, the area with large flow and high density and the area with small flow and low density can be effectively determined, and a basis is provided for subsequent management and control.

[0133] The application provides a traffic management and control method combining dynamic and static, which performs label similarity analysis on all management and control labels, and retrieves management and control modes from a management and control database, including:

[0134] A color array is set for the corresponding sub-range according to the management and control label of each sub-range, wherein the color array includes: an index type of a management and control index contained in the corresponding management and control label, a display color matched with the index type, an index value matched with the index type, and an identification size matched with the index value.

[0135] Color similarity analysis is performed based on all color arrays to classify all sub-ranges by range;

[0136] The concentrated color similarity analysis result in the same classification result is determined, and the first range corresponding to the concentrated color and the second range below the concentrated color are locked, and the third range above the concentrated color is also locked.

[0137] A first management and control mode matched with the first range is retrieved from the management and control database, and the first range and the second range are subjected to corresponding management and control;

[0138] A second management and control mode matched with the third range is retrieved from the management and control database, and the third range is subjected to corresponding management and control.

[0139] In this embodiment, the management and control index refers to a congestion index corresponding to dynamic and static, so as to determine the corresponding management and control index, the greater the role of the management and control index, the deeper the corresponding display color, and the greater the value of the corresponding index, the larger the corresponding identification display.

[0140] In this embodiment, the control indicators include indicators 1, 2 and 3, wherein indicator 1 belongs to type 1, indicator 2 belongs to type 2, and indicator 3 belongs to type 3, the display color of indicator 1 is light gray, the display color of indicator 2 is medium gray, and the display color of indicator 3 is dark gray, wherein the indicator value of indicator 1 is 1, the original identification size is kept unchanged, the indicator value of indicator 2 is 0.5, and the original identification is reduced to half of the original, and the indicator value of indicator 3 is 2, and the original identification is enlarged to half of the original.

[0141] By determining the color and the identification size, the similarity between the arrays can be effectively determined.

[0142] For example, sub-range 1: indicator 1: light gray, original identification size, indicator 2: non-existent, and indicator 3: non-existent.

[0143] Sub-range 2: indicator 1: light gray, original identification size, indicator 2: medium gray, original identification size, and indicator 3: non-existent.

[0144] Sub-range 3: indicator 1: non-existent, indicator 2: non-existent, and indicator 3: dark gray, original identification size.

[0145] After the similarity analysis, the ranges are classified: sub-range 1 and sub-range 2 are one category, and sub-range 3 is one category.

[0146] Among them, the color similarity analysis result is concentrated, for example, light gray is the concentrated color, the corresponding first range is sub-range 1, the second range does not exist, and the third range is sub-range 2.

[0147] In this embodiment, the control database includes the combined color and the combined identification size of various different indicators and the control method matched with the combined result, for example, indicator 1 is for congestion, the more congested, the larger the corresponding identification, and then measures such as dredging are required.

[0148] In this embodiment, the second range and the first range are controlled in the same way because the traffic of the second range is definitely better than that of the first range, and in the case of the first range being reasonable, the second range is also reasonable, so the same control method can be used.

[0149] In this embodiment, the traffic control difficulty of the third range is greater than that of the second range, so the third range needs to be controlled specifically, that is, the control method of the first range and the second range is consistent, and the control method of each third range is inconsistent.

[0150] The beneficial effects of the above technical solutions are: classifying the sub-ranges according to colors, facilitating effective control of the sub-ranges, and ensuring high-level control of traffic.

[0151] The application provides a traffic control system combining dynamic and static, which comprises Figure 2 As shown in the figure, comprising:
