Description

Technical Field

[0001] The present invention relates to the technical field of traffic light system setting, and in particular to a traffic light system setting method for preventing traffic jams. Background Art

[0003] If the patent for the systematic setting of traffic lights is adopted, the existing traffic facilities can be used most effectively, and the huge pressure of urban traffic congestion can be alleviated exponentially in the most convenient, economical and ingenious way, saving passengers' precious time and greatly saving the investment in the construction of urban traffic facilities, which will have a universal and huge impact on the global society.

[0004] After searching, the Chinese patent publication number CN112071088B discloses a traffic light control method for preventing traffic jams, using a traffic light control system for preventing traffic jams, which is specifically implemented in the following steps:

[0005] Step 1, collecting the speed V of vehicles near the road section;

[0006] Step 2, comparing the speed V of the vehicles attached to the road section collected in step 1 with the critical speed of the road section set by the system. If the speed V of the vehicles attached to the road section is less than the minimum critical speed Vmin, the road section is in a traffic jam state, and step 3 is executed; if the speed V of the vehicles attached to the road section is less than the maximum critical speed Vmax of the vehicle, the road section is in a smooth state, and the road traffic information is directly fed back to the user terminal 8;

[0007] Step 3: Plan the optimal route and send it according to the user's destination and the speed information of each road section.

[0008] This type of patent estimates the number of vehicles through radar sensors. The traffic condition monitoring module in the main system will compare the measured speed with the preset value logically, determine the traffic condition level of the traffic light intersection, and feed back the information to the user end. The optimal path planning module pushes the most suitable path to the user to avoid the aggravation of traffic jams. Although this method can alleviate the aggravation of traffic jams to a certain extent, after the main line intersection is congested, due to the limited number of vehicles passing through the traffic lights in a cycle, once the next traffic light is in the red light state, it cannot pass, making the traffic flow unable to be continuous and smooth, which aggravates the congestion, and such extension may cause congestion in a larger range! In view of this, the present invention proposes a traffic light system setting method for efficiently preventing traffic jams. Summary of the invention

[0009] The present invention proposes a systematic setting method of traffic lights for preventing traffic jams, which solves the common problem in the prior art that the timings of adjacent traffic lights are disordered, the traffic flow cannot be kept continuous and smooth, and the traffic jam is aggravated.

[0010] The technical solution of the present invention is as follows: A method for setting a traffic light system to prevent traffic jams, comprising the following steps:

[0011] S1: Preparation for setting: 2 to 3 traffic policemen who are proficient in setting traffic lights should first be familiar with the operation steps of the patent, which requires distance meter, walkie-talkie, and calculator auxiliary tools, and should be arranged during the time period with the least traffic flow or late at night;

[0012] Send one or two proficient personnel to follow up and inspect, so as to solve the problem once and for all. Otherwise, a mistake in one place will lead to serious consequences for the entire area.

[0013] Traffic police were dispatched to direct vehicles to pass normally;

[0014] S2: Accurately preset the traffic light operation cycle for each direction:

[0015] The time when traffic lights release traffic in each direction is called an operation cycle T. The standard is that traffic in each direction is basically finished, and the time on the main road is longer than that in other directions. If the time is set too short, the traffic will not be finished. If it is too long, it will cause waiting, which will hinder the traffic flow. Therefore, we should first conduct research, abandon the two extremes of comprehensive evaluation, and find the appropriate setting time for each direction close to the peak of traffic flow; and this cycle time should not be changed before there is a large diversion of vehicles;

[0016] S3: Select the traffic lights on the main roads with the greatest traffic pressure in the city center as the benchmark:

[0017] Use traffic flow detection equipment to detect the trunk line with the largest traffic flow, and then select the traffic light with the largest traffic flow on the trunk line as the benchmark traffic light (traffic police are actually most familiar with the trunk lines and traffic lights that are often congested);

[0018] S4: Calculate the mileage time between traffic lights:

[0019] The distance S1 from the reference traffic light to the next traffic light on the trunk line is measured by a distance meter, and then the time period t1 required for the vehicle to travel from the reference traffic light to the next traffic light is calculated according to the speed V allowed by the traffic bureau on that section of road;

[0020] The calculation formula is as follows: t1 = S1 / V;

[0021] S5: Calculate the next traffic light start time:

[0022] Set the main line traffic light cycle to T, divide the travel time between two traffic lights by the traffic light cycle T, and ignore the same cycle, and get the remainder time t2;

[0023] S6: Settings:

[0024] The benchmark traffic light first inputs the standard traffic light operation cycle and confirms the operation;

[0025] The next traffic light also sets the standard operation cycle and waits for confirmation;

[0026] The timer starts from the first second of the green light of the benchmark traffic light. When the timer runs out of the remainder time t2, it is the first second of the green light of the next traffic light. Click to confirm the operation.

[0027] S7: The next traffic light is used as the reference for setting the third traffic light of the main line. The actual distance between the two is measured, and the travel time is calculated. The previous steps are followed, and so on, to complete the setting of this main line.

[0028] The main arterial traffic lights were then used as a benchmark and each road was set horizontally, all the way to the countryside where traffic lights were sparse.

[0029] After this setup is completed, all vehicles will be able to travel smoothly with green lights all the way, which will not only save passengers a lot of time, but also make full use of transportation facilities and avoid a lot of waste.

[0030] The working principle and beneficial effects of the present invention are as follows: by setting a reference traffic light and calculating the passage time of batches of vehicles from the reference traffic light to the next traffic light, the green light start time of the next traffic light is set, and then the green light start time of the third traffic light is calculated using the traffic light as the reference traffic light, and so on. The start time of all the traffic lights on the main line can be set, so that vehicles in each direction will be able to pass through batches of green lights all the way, passengers will save a lot of time, traffic pressure will be greatly relieved, and the huge investment in transportation facilities will be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Figure 1 The present invention is a flow chart of a method for setting a traffic light system for preventing traffic jams. DETAILED DESCRIPTION

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, this embodiment proposes a traffic light system setting method for preventing traffic jams, including the following steps:

[0035] S1: Setup preparation:

[0036] Assign 2 to 3 traffic policemen who are proficient in setting traffic lights, familiarize themselves with the operation steps of the patent first, and need to be equipped with distance meters, walkie-talkies, and calculators to assist. The time should be arranged during the time period with the least traffic volume or late at night, and one or two proficient personnel should be dispatched to follow up and inspect, so as to solve the problem once and for all. Otherwise, a mistake in one place will lead to serious consequences for the entire area.

[0037] Dispatch traffic police to coordinate and direct traffic and prevent congestion;

[0038] S2: Accurately preset the traffic light operation cycle for each direction:

[0039] The time it takes for traffic to be released in each direction at a traffic light to run once is called an operation cycle T. The standard is that traffic in each direction has basically been released, and the time on the main road is longer than that in other directions.

[0040] If the time is set too short, the traffic will not be able to run completely. If it is too long, it will cause waiting, which will hinder the traffic flow. Therefore, we should first conduct research, abandon the two extremes of comprehensive evaluation, and find the appropriate time for each direction close to the peak of traffic flow.

[0041] And this cycle time should not be changed before a large amount of diversion occurs;

[0042] S3: Select the traffic lights on the main roads with the greatest traffic pressure in the city center as the setting benchmark:

[0043] Through the traffic flow detection equipment, the trunk line with the largest traffic flow is detected, and then the traffic light with the largest traffic flow on the trunk line is selected as the benchmark traffic light (the traffic police are most familiar with the trunk lines and traffic lights that are often congested);

[0044] S4: Calculate the mileage time between traffic lights: Use a distance meter to measure the distance S1 from the base traffic light on the trunk line to the next traffic light on the trunk line, and then calculate the time period t1 required for the vehicle to travel from the base traffic light to the next traffic light according to the speed V allowed by the traffic bureau on that section of road. The calculation formula is as follows: t1 = S1 / V;

[0045] S5: Calculate the next traffic light start time:

[0046] Set the main line traffic light cycle to T, divide the travel time between two traffic lights by the traffic light cycle T, and ignore the same cycle, and get the remainder time t2;

[0047] S6: Settings:

[0048] The benchmark traffic light first inputs the standard traffic light operation cycle and confirms the operation;

[0049] The next traffic light also sets the standard operation cycle and waits for confirmation;

[0050] The timer starts from the first second of the green light of the benchmark traffic light. When the timer runs out of the remainder time t2, it is the first second of the green light of the next traffic light. Click to confirm the operation.

[0051] S7: The next traffic light is used as the reference for setting the third traffic light of the main line. The actual distance between the two is measured, and the travel time is calculated. The previous steps are followed, and so on, to complete the setting of this main line.

[0052] The main arterial traffic lights were then used as a benchmark and each road was set horizontally, all the way to the countryside where traffic lights were sparse.

[0053] After this setup is completed, all vehicles will be able to travel smoothly with green lights all the way, which will not only save passengers a lot of time, but also make full use of transportation facilities and avoid a lot of waste.

[0054] By setting a reference traffic light and calculating the passing time of batches of vehicles from the reference traffic light to the next traffic light, the green light start time of the next traffic light is set, and the green light start time of the third traffic light is calculated using this traffic light as the reference traffic light, and so on. After setting the start time and cycle of all traffic lights on the main line, vehicles in each direction will pass through batches of green lights all the way, which will greatly relieve traffic pressure.

[0055] The systematic setting of the traffic lights of the present invention can make the most effective use of existing traffic facilities, and can alleviate the huge pressure of urban traffic congestion in the most convenient, economical and ingenious way, saving the valuable time of passengers and drivers, and can also save a lot of investment in the construction of urban traffic facilities, which will have a universal and huge impact on the global society.

[0056] The above are merely implementation steps of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
