Description
Technical Field
The invention belongs to the field of road traffic control, and particularly relates to a traffic operation system and method.
Background
In the existing road traffic of China, various traffic signal lamps such as red light, green light, yellow light and the like respectively play their roles, and the traffic order of roads is maintained by combining with established traffic rules. However, the current traffic signal lights and the traffic operation methods combined with the traffic signal lights are all relatively rigid, that is, the indication operation of the road traffic can only be switched rigidly according to the preset time value, the preset time value is the fixed time of a certain lane which is common in the intersection, so that the adjustment can not be made according to the actual condition of the road traffic, for example, the traffic flow is obviously different under different time periods and different lanes, and if an accident occurs at a certain position, the condition is more so, but aiming at the condition, the current indication operation of the traffic can only be performed with traffic guidance or additional manual drainage according to the fixed time value, and the corresponding adjustment action can not be performed according to the real-time condition of the road. Under the condition, the driving time and energy are wasted very much, and the traffic is not humanized, for example, at intersections with obviously concentrated traffic flow directions, the traffic flow of some directional lanes is obviously more, while some directional lanes are few, but all directional lanes need to be operated in sequence according to fixed timing, so that the fixed timing of less directional lanes of the traffic is wasted, while the fixed timing of more directional lanes of the traffic is far insufficient, so that the traffic jam is easily caused, and the smooth operation of traffic is influenced.
Because of the above-mentioned shortcomings of the existing road traffic regulations, many enterprises and individuals develop various traffic operation systems and methods by various methods, and some of them are applied in small scale. For example, the intelligent transportation scheme proposed by Mr. Mayun does not make a small progress in the actual road test, and does have the advantages of saving driving time and energy to a certain extent, and for example, the invention patent "real-time mobile communication type intelligent transportation method" of Chinese patent No. ZL201210143686.0 and the like, and the schemes for traffic operation all have certain advantages, but through careful analysis, the schemes can be known to achieve the effect of intelligent transportation by collecting all traffic data, and performing judgment and feedback through analysis and processing of big data. However, these schemes are extremely dependent on analysis and judgment of big data, and nowadays, the reliability of this method is not high, and relatively speaking, the reliability of the traditional preset method is higher, and it is not easy to have a fault, so at present, the traffic operation is still performed by adopting the traditional preset method. However, as described above, there is a large driving time and energy waste in the current traffic operation system and method set in advance, so that there is a great room for improvement in the current traffic operation system and method on the basis of ensuring the operation reliability.
Disclosure of Invention
(1) Technical problem to be solved
Aiming at the defects of the prior art, the invention aims to provide a traffic operation system and a method, aiming at solving the technical problems that the operation timing of traffic lanes in all directions cannot be adjusted according to the real-time condition in the prior art, so that the operation timing of the lanes in all directions is unreasonable, the fixed timing of some lanes is wasted, and the fixed timing of some lanes is insufficient, so that lane congestion is caused, the smooth operation of traffic is influenced, and the driving time and energy are wasted; on the basis of guaranteeing operational reliability through this technical scheme, according to the operation timing of real-time condition in time optimization adjustment each position lane, under the unchangeable circumstances in the time of guaranteeing each position lane self is fixed, utilize all transit times of each position lane effectively, improve the current efficiency of traffic, guarantee the smooth and easy operation of traffic, and then save driving time and energy.
(2) Technical scheme
In order to solve the technical problem, the invention provides a traffic operation system which comprises traffic signal lamps and a control device, wherein the traffic signal lamps are arranged in all directions in an intersection and are respectively in electric signal connection with the control device.
Preferably, the length of the real-time detection zone is 50 meters; the length of the real-time detection area is 50 meters, and the method can be optimally suitable for subsequent traffic operation by setting the length of the real-time detection area to be 50 meters, so that the convenience of the traffic operation method is improved, the traffic efficiency is improved, the smooth operation of traffic is ensured, and the driving time and energy are saved.
The traffic signal lamp is a common signal lamp, and can receive the control of the control device, so that the traffic signal lamp can display indicating light such as red light, green light, yellow light and the like, and further carry out light command on the intersection; the control device is a common controller, can receive a signal detected by the real-time detection area, namely a signal indicating whether a vehicle exists or not detected by the detection device in the real-time detection area, and controls the traffic signal lamp to display differently through a preset program. The crossroad is a three-fork or crossroad, the position-bearing lane is a single lane, each single lane is called a position-bearing lane in the command of actual traffic, and in the crossroad, the position-bearing lane in which the automobile advances to the center of the crossroad is forward direction, and the position-bearing lane in which the automobile advances to the position-bearing lane is backward direction far away from the center of the crossroad, so that the position-bearing lane in each forward direction in the crossroad is an inlet of each forward position-bearing lane into the center of the crossroad, and each real-time detection zone which contains a detection device and is used for detecting whether the automobile exists in the zone per se is respectively arranged, the detection device is generally a buried induction line, whether the automobile exists in the zone per se is sensed in real time through the induction line in the real-time detection zone, and the detection devices in each real, and sending the signal detected in real time to a control device to finish detection feedback.
The traffic running method is a breakthrough improvement on the basis of the existing traffic running, namely, a traffic signal lamp and a control device are unchanged, on hardware, a section of real-time detection area which is provided with a detection device inside and used for detecting whether vehicles exist in the area of the detection area is respectively arranged at each forward direction position lane in the intersection, and meanwhile, the detection devices in each real-time detection area are respectively connected with the control device through electric signals to realize signal transmission. The invention is characterized in that the method for controlling the traffic lights in the whole large direction and sequence is not changed, or the method for controlling the traffic lights is controlled according to the conventional method, namely, the fixed time of each bit lane for straight running, left turning or right turning is consistent with the original time, and when the fixed time of a bit lane for straight running, left turning or right turning is finished, the next operation indication is carried out according to the sequence of the existing method, namely, for example, after the fixed time of a left turning green light of a bit lane is finished, the yellow light is firstly changed for a period of time, and then the yellow light is changed into the red light in a short time, meanwhile, the straight green light of the adjacent bit lane is lightened, and the display is carried out according to the preset fixed time, so that the traffic is carried out according to the front and back sequence of the original each bit lane. Therefore, the sequence of fixed timing of the bit lanes and the indication change is the same as that of the prior art, and the invention only transfers the fixed timing in the period of time of the bit lane to the bit lane in the next sequence by a corresponding method when a bit lane is in a green light state capable of passing but no vehicle passes, and if the bit lane in the next sequence still has no vehicle to pass, the process is analogized, thereby realizing the optimization adjustment of the running timing of each bit lane, effectively utilizing all the running time of each bit lane under the condition of ensuring that the fixed timing of each bit lane is not changed, improving the traffic efficiency, ensuring the smooth running of traffic, further saving the driving time and energy, and simultaneously ensuring the reliability of the traffic running.

if the detection device continuously detects that no vehicle exists in the real-time detection area of the first vector lane and the remaining time of fixed timing in the first vector lane is greater than the safety time threshold value, the control device controls the traffic signal lamp of the first vector lane to be switched to a yellow lamp and controls the traffic signal lamp of the first vector lane to be switched to a red lamp after the control device keeps a period of switching buffer time; meanwhile, the control device controls the detection device in the real-time detection area of the second direction lane allowing the vehicles to pass in the next time sequence of the first direction lane to detect whether the vehicles exist in the area, if the detection device detects that the vehicles exist in the real-time detection area of the second direction lane, the control device controls the traffic signal lamp of the second direction lane to be switched from red to green, allows the vehicles in the second direction lane to pass in the time period, and after the fixed time of the first direction lane is finished, the traffic signal lamp is switched again; if the detection device detects that no vehicle exists in the real-time detection area of the second directional lane, the control device controls the detection device in the real-time detection area of the third directional lane allowing vehicles to pass in the next time sequence of the second directional lane to detect whether the vehicle exists in the area of the detection device, and the like, until the vehicle exists in the real-time detection area of a certain directional lane, the control device controls the traffic signal lamp of the directional lane to be switched from the red lamp to the green lamp, allows the vehicles in the directional lane to pass in the time period, and after the fixed timing of the first directional lane is finished, the traffic signal lamp is switched again; during the fixed timing of the first heading lane, if the detection device subsequently detects that vehicles exist in the real-time detection area of the first heading lane, the control device controls the traffic signal lamp of the first heading lane to keep a switching buffer time and then switch to be a green lamp, the vehicles in the first heading lane are allowed to pass, and the traffic signal lamps of other heading lanes are immediately switched to be yellow lamps and are switched to be red lamps after keeping the switching buffer time; if the detection device detects that no vehicle exists in the real-time detection areas of all the directional lanes, the control device controls the traffic signal lamp of the first directional lane to be switched from the red lamp to the green lamp, continues to allow the vehicle in the first directional lane to pass in the time period, and switches the traffic signal lamp after the first directional lane is fixed.
Preferably, the safety time threshold is 5 seconds, and the switching buffer time is 3 seconds; that is, a certain heading lane is in the fixed time when the vehicle is allowed to pass, but the detection device continuously detects that no vehicle exists in the real-time detection area of the heading lane, it needs to first determine whether the remaining time of the fixed time in the heading lane exceeds 5 seconds, if the remaining time of the fixed time in the heading lane is less than 5 seconds, the traffic light of the heading lane is not changed, or the traffic light is changed according to the original operation rule, if the remaining time of the fixed time in the heading lane is more than 5 seconds, the traffic light of the heading lane is changed according to the operation method; the switching buffer time is 3 seconds, namely the staying time of the normal yellow light, thus conforming to the continuation of the existing rule; so safe time threshold is 5 seconds, can set to 50 meters corresponding with real-time detection zone length, combines to switch buffer time simultaneously and is 3 seconds, can guarantee like this that vehicle meets an emergency and the security of traffic operation among the traffic signal lamp switching better, improves the utilization ratio of each time threshold simultaneously, and then promotes the current efficiency and the convenience of traffic operation, guarantees the smooth and easy operation of traffic, and then saves driving time and the energy.
