Technical Field

The application of the intelligent traffic light can effectively improve the passing efficiency of vehicles and pedestrians. The intelligent traffic lights used in current urban intersections mainly include: the traffic light with fixed reading time, the traffic light controlled according to the traffic flow and the traffic light controlled according to the number of pedestrians at the intersection.

For example, at intersections with large pedestrian flow, such as parks, malls, etc., pedestrians may increase continuously and rapidly at the intersections in a short time, and if traffic lights are controlled only according to the number of pedestrians, the red lights of the zebra crossing will change into green lights in a short time, which seriously affects the traffic efficiency.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The traffic signal lamp control methods mentioned in the background art all have certain disadvantages, so the present disclosure provides a more efficient and intelligent traffic signal lamp control method based on the number of pedestrians, the attributes of the pedestrians, the waiting time of the pedestrians, and the passing time of vehicles.
Referring to fig. 1, fig. 1 is a flowchart illustrating a traffic signal light control method according to an exemplary embodiment of the disclosure. The traffic signal lamp control method shown in fig. 1 includes the steps of:
in step S201, the current waiting tolerance of each pedestrian who enters the waiting area of the target intersection within the duration is acquired during the duration in which the traffic light of the target intersection displays the first light signal.
For example, the first light signal is a signal indicating vehicle passing and pedestrian waiting, and the first light signal may be a red light signal.
In one embodiment, high-definition cameras can be erected on two sides of a target intersection where a traffic signal lamp is located, the current duration of a red light signal is obtained in real time, the actual waiting time of each pedestrian entering a waiting area of the target intersection within the duration of the red light signal is obtained in real time, the waiting tolerance of the pedestrian is calculated based on the actual waiting time of the pedestrian, and the waiting tolerance is used for representing the tolerance degree of the pedestrian to the waiting time.
It should be noted that step S201 may further include sub-step S2011 and sub-step S2012, and a specific manner of acquiring the waiting tolerance of each pedestrian will be described in detail in the sub-step of step S201. Referring to fig. 2, fig. 2 is a flowchart illustrating sub-steps of step S201 according to an exemplary embodiment of the present disclosure.
In sub-step S2011, pedestrian data entering a waiting area of the target intersection for a duration is acquired.
Illustratively, the pedestrian data includes the number of pedestrians, and the actual waiting time period for each pedestrian to enter the waiting area.
In sub-step S2012, the current waiting tolerance of each pedestrian is calculated based on the number of pedestrians and the actual waiting time period for each pedestrian to enter the waiting area.
For example, the formula for calculating the current waiting tolerance of each pedestrian includes:
wherein, y (x)i) Is the waiting tolerance of the pedestrian i; xiThe actual waiting time for the ith entering into the waiting area; t is a preset constant and is used to represent a waiting time threshold when an average adult waits at the intersection for a tolerance, and T can be obtained based on experience, for example, it can be set that the average adult waits at the intersection for a tolerance when the waiting time at the intersection is T seconds, for example, if the waiting time of the adult is less than T seconds, the waiting time is less than 1 tolerance, and if the waiting time of the adult is greater than T seconds, the waiting time of the adult is greater than 1 tolerance; α is a preset constant greater than 1, and the value of α may be adjusted, for example, α may be 1.5.
Note that the calculation formula of the wait tolerance is a nonlinear relationship, and when α is 1.5, for example, when the actual wait time is
At second, its wait tolerance is not 0.5, but
Less than 0.5; when the actual waiting time is 2T seconds, the waiting tolerance is not 2 but
Greater than 2; the value of alpha can be adjusted.
In step S202, the current overall pedestrian tolerance of the waiting area is calculated based on the current waiting tolerance of each pedestrian.
Illustratively, the pedestrian data further includes pedestrian attributes including adults, elderly people, and children, and the number of pedestrians further includes the number of adults, elderly people, and children. The pedestrian attributes can be acquired through high-definition cameras erected on two sides of the target intersection to obtain pedestrian images, models for identifying the pedestrian attributes are trained through machine learning or deep learning according to the acquired pedestrian images, and the trained models are used for identifying pedestrians specifically to be children, adults or old people.
The current calculation formula for overall pedestrian tolerance includes:
where N is the number of pedestrians, and q (i) is a coefficient determined based on the pedestrian attribute of the pedestrian i, for example, in one embodiment, when the pedestrian attribute is elderly, q (i) may take a value of 2, and when the pedestrian attribute is children, q (i) may take a value of 2
When the pedestrian attribute is adult, q (i) may take the value 1; in another embodiment, q (i) may take a value of 3 when the pedestrian attribute is elderly, q (i) may take a value of 2 when the pedestrian attribute is children, and q (i) may take a value of 1 when the pedestrian attribute is adults; the specific value of (A) can be adjusted according to the practical application; q (i) y (x)i) For pedestrian i current wait tolerance, XiThe actual waiting time for the ith entering into the waiting area; t is a preset constant and is used for representing a waiting time threshold value when the average adult waits at the intersection for a tolerance, and T can be obtained based on experience, for example, the adult can be set to reach a tolerance when the waiting time at the intersection is T seconds, for exampleIf the waiting time of the adult is less than T seconds, the tolerance is less than 1, and if the waiting time of the adult is more than T seconds, the tolerance is more than 1; α is a preset constant greater than 1, and the value of α may be adjusted, for example, α may be 1.5. The calculation method is consistent with that described in sub-step S2012, and specific reference may also be made to specific contents of sub-step S2012.
In step S203, the state of the traffic light is adjusted according to the duration and the overall pedestrian tolerance.
Illustratively, the duration is the time indicating vehicle traffic and pedestrian waiting, i.e., the current duration of the red light signal.
The specific way of adjusting the state of the traffic signal lamp may be: when the total pedestrian tolerance is greater than or equal to a predetermined threshold value and the duration is less than a predetermined time length, adjusting the state of a traffic signal lamp, and adjusting the traffic signal lamp from a state of displaying a first lamp signal to a state of displaying a second lamp signal, wherein the first lamp signal is used for indicating vehicle passing and pedestrian waiting, and the second lamp signal is used for indicating the lamp signal of pedestrian passing; the preset threshold is a preset reasonable value, which represents the acceptable waiting time of the pedestrian in the waiting area of the target intersection, and can be obtained based on experience, and the specific value is not limited herein.
The specific way of adjusting the state of the traffic signal lamp may also be: when the total pedestrian tolerance is less than the predetermined threshold and the duration is equal to the predetermined time, adjusting the state of the traffic light, i.e., adjusting the traffic light to a signal state indicating vehicle waiting and pedestrian passing, in one embodiment, adjusting the red light signal state to a green light signal state; the preset time is a fixed time for indicating vehicle passing and pedestrian waiting, the preset time can be, but is not limited to, 30 seconds, 40 seconds or 60 seconds, and the specific value can be reasonably set according to the traffic condition of the specific intersection, which is not limited herein.
It should be noted that the duration of the second light signal may also be adjusted based on pedestrian data, which may be attributes of pedestrians and the number of pedestrians, for example, before the red light signal state is adjusted to the green light signal state, if the total number of the elderly and children detected in the waiting area of the target intersection is greater than a preset threshold, a reasonable fixed duration may be added on the basis of the fixed duration of the existing green light signal, such as 5 seconds, 10 seconds, and 15 seconds. For example, the preset threshold may take values of, but is not limited to, 5, 6, and the like, and the value of the fixed duration may depend on the size of the fixed duration of the existing green light signal, and the longer the fixed duration of the existing green light signal is, the smaller the value of the fixed duration is, the shorter the fixed duration of the existing green light signal is, the larger the value of the fixed duration is. For example, if the fixed duration of the existing green light signal is already relatively long, such as 60 seconds, the fixed duration may be 0, if the fixed duration of the existing green light signal is already relatively moderate, such as 40 seconds, the fixed duration may be 10 seconds, and if the fixed duration of the existing green light signal is relatively short, such as 20 seconds, the fixed duration may be 15 seconds. So that the elderly and children waiting in the waiting area can smoothly pass through the target intersection. The pedestrian attribute of the pedestrian waiting in the intersection waiting area can be acquired, the duration of the pedestrian passing state is adjusted based on the pedestrian attribute, and the pedestrian passing state is convenient for the old, children and other special crowds to pass.
When the green light signal state is finished and the traffic signal light returns to the red light signal state again, step S201 and step S202 are repeated.
It should be noted that the traffic light control method provided by the present disclosure may also be applied to scenes where pedestrians wait to pass, such as scenic spots and exhibition halls. For example, in a scenic spot where the pedestrian volume is large, a large number of people to be passed may be gathered in a short time in the waiting area of the traffic light intersection of the scenic spot, and the above-mentioned formula for calculating the total pedestrian tolerance is applied
To calculate the overall pedestrian tolerance of the group to be passed, in view of the general amongst the group to be passed in the scenic spotThe special crowd such as a large amount of children, the old man, the value of special crowd Q (i) can be great, total pedestrian tolerance can just reach predetermined threshold value very easily this moment, for example, the vehicle duration of passing at this moment may only be 20 seconds, but consider that a large amount of crowds in the scenic spot wait to pass, the current demand of scenic spot is more do benefit to the short vehicle duration of passing like this in fact, the long-time waiting of a large amount of crowds in the crossing has been avoided, crowd has been avoided, the accident of trampling that can appear has also been avoided. The traffic efficiency of vehicles and pedestrians at the intersection is improved, and the traffic demands of the vehicles and the pedestrians at the intersection are scientifically and reasonably solved.
In summary, the method can acquire the waiting tolerance of the pedestrians waiting in the intersection waiting area within the passing duration of the vehicles, then calculate the current total pedestrian tolerance according to the waiting tolerance of each pedestrian, adjust the state of the traffic signal lamp according to the duration and the total pedestrian tolerance, and simultaneously give consideration to the passing efficiency of the vehicles and the passing demands of the pedestrians, can be effectively applied to intersections such as parks and shopping malls with large pedestrian flow, improve the passing efficiency of the vehicles and the pedestrians at the intersections, and scientifically and reasonably solve the passing demands of the vehicles and the pedestrians at the intersections; simultaneously this openly can also acquire the pedestrian's attribute of waiting at the crossing waiting area, and the duration of the traffic signal lamp's instruction pedestrian traffic state is adjusted based on pedestrian attribute, has made things convenient for special crowds ' such as old man, children to pass.
