Description

Variable one-way traffic signal system {CHANGEABLE ONE-WAY TRAFFIC SIGNAL SYSTEM}

The present invention relates to a variable one-way traffic signal system, and more particularly, a variable one-way that controls a signal of an entrance part so that vehicles entering from both sides can communicate without matching each other on a road where only one vehicle can pass. A traffic signal system.

In general, vehicles entering from both sides of the road where the width of the road can pass only one vehicle correspond to each other in the middle so that one vehicle backs down or crosses the road. Due to this inconvenience, a fixed one-way road that proceeds in only one direction is executed, but this causes a problem of returning to the destination. In addition, when one lane is closed due to construction, people carry radios on both sides of the road and carry out a road signal, which causes labor costs.

In addition, there is a problem that the parking space is reduced because the intersection must be secured in the middle for the intersection.

The present invention is to provide a variable one-way traffic signal system that allows the vehicles entering from both sides to communicate without having to correspond to each other while securing a parking space by controlling the signal of the entrance part by placing traffic lights on both sides to solve the above problems. It is an object of the present invention.

In order to achieve the above object, the present invention, in the traffic signal system, the device (1, 2, 3, 4, 5, 6, 7, 8) for detecting the entry and exit of the vehicle on both sides of the access road Intelligent traffic that has traffic lights (9, 10, 11) to signal the entry or not, and analyzes the information about the entrance and exit direction of the vehicle and the number of vehicles entered by the entrance and exit detection device, and is connected to the traffic lights of both access roads and controlled. It is characterized in that the signal controller 12 is provided.

Hereinafter, described in detail by the accompanying drawings as follows.

1 is a state of entry and exit on the road that the width of the road can pass only one vehicle,

The present invention relates to a variable one-way traffic signal system that controls a signal of an entrance part so that vehicles entering from both sides can communicate without corresponding to each other.

You can see the progress of the vehicle by the order of two detectors placed side by side.For example, when detected as 1, 2, 1, 2 (front wheels 1, 2, rear wheels 1, 2) (Hereinafter referred to as 1212) shows that the vehicle entered the one-way street at the entrance (a), the number of vehicles to go out is increased. To list each example, 1212 = (A) Entry = +1, 2121 = (A) Exit = -1, 4343 = (B) Entry = +1, 3434 = (B) Exit = -1 The number of vehicles to do is calculated.

FIG. 3 is a view showing a traffic light and FIG. 4 is a flowchart for entering and leaving a vehicle in a road width of a vehicle.

In the state where there is no vehicle on the first one-way road (entry vehicle: 0 units), the traffic light of No. 9 and No. 10, such as the traffic light of Fig. 3A, is used as a green signal so that both can enter. It is judged whether it is detected by detection devices 1 and 4 of both driveways. If 1 is detected, traffic light 10 is red signal and if 4 is detected, signal 9 is red signal to prevent entry of the opposite vehicle. do. If the number of vehicles to go out is +1 by the incoming signal of the vehicle as above, and the number of vehicles to go out is -1 by the departure signal of the vehicle as -1, the signal to go out continues to be signaled. It is calculated to wait, and when the entrance +1 and exit -1 is continuously calculated and becomes 0, the first vehicle does not exist and both traffic lights become green signals.

This is shown in the table below.

Calculation Order end I No entry 0 0 rust rust (B) mouth 4343 +1 One enemy rust (B) mouth 4343 +1 2 enemy rust Exodus 2121 -One One enemy rust Exodus 2121 -One 0 rust rust

By controlling the opposite direction in the same way as above, the vehicles on both sides can communicate without correspondence.

If there is a waiting state of both vehicles, a vehicle detection sensor or a driver-operated switch is placed at the entrances of both sides to prevent entry of only one vehicle. That is, 7 and 8 of FIG. 1 are sensors or switches for determining whether there is a waiting vehicle, and when a certain time has elapsed while there is a signal at the opposite waiting vehicle sensor (vehicles A and B), the traffic light entering red is turned red. To prevent further entry and equalize entry by both sides.

This is shown in the table below.

Calculation Order end I No entry 0 0 rust rust (B) mouth 4343 +1 One enemy rust (B) mouth 4343 +1 2 enemy rust (B) mouth 4343 +1 3 enemy rust Exodus 2121 -One 2 enemy rust Detected and time-lapse 0 2 enemy enemy Exodus 2121 -One One enemy enemy Exodus 2121 -One 0 rust enemy Mouth1212 +1 One rust enemy

By controlling in the above-described way, the vehicles on both sides can communicate fairly and efficiently without traffic.

FIG. 2 is an example of a case of entering and exiting a one-way road that serves as a roadside parking. In the drawing of FIG. The entrance barrier 13 is added, and the traffic light 9 in the area (C), which is an intermediate passage, is in the form of a turn signal as shown in FIG. 3B, and FIG. 5 is a flowchart of FIG.

1212 = (A) Entrance = +1, 2121 = (A) Exit = -1, 4343 = (B) Entrance = +1, 3434 = (B) Exit = -1 Parking area 56 = (parking) entry = -1, 65 = (parking) exit = +1 is added and calculated.

This is shown in the table below.

Calculation Order end All I S1 No entry 0 0 rust <= => rust S2 (Parking) Expedition 6565 +1 One enemy <= => enemy S3 2121 or 3434 -One 0 rust <= => rust S4 No entry 0 0 rust <= => rust S5 (B) mouth 4343 +1 One enemy <= rust S6 (B) mouth 4343 +1 2 enemy <= rust S7 (Parking) mouth 5656 -One One enemy <= rust S8 Exodus 2121 -One 0 rust <= => rust S9 (B) mouth 4343 +1 One enemy <= rust S10 (Parking) Exit 6525 +1 2 enemy <= rust S11 Exodus 2121 -One One enemy <= rust S12 Exodus 2121 -One 0 rust <= => rust

When described in detail by the above figures and tables as follows.

When the 6565 is detected in the state S1 as in the vehicle F of FIG. 2 without the vehicle to be exited, the vehicle to be exited is increased as the state in which the parked vehicle detects the movement for leaving (S2) is +1. Both lights turn red because they do not know which direction to go out. If 2121 or 3434 is detected, it indicates exit and returns to the original state (S4) as in S3. If 5656 are detected as shown in the vehicle E of FIG. 2 after two vehicles are entered in (B) (S5, S6), one of the occupied vehicles enters the parking area and is calculated as -1 (S7). ). When the remaining one is disengaged (S8), the first state becomes. In the state in which the traffic light 11 of FIG. 5 is provided in the direction of the traffic light in the direction to be exited, therefore, the vehicle leaving the vehicle (S9) sees (<=) of the traffic light 11 in a state in which one vehicle enters 4343 The number of vehicles to be taken out and calculated to be +1 is two, and 2121 two times (S11, S12), all vehicles are taken out and become the first state.

Contrary to the signal in the direction of travel, if it is detected as 12 or 1212 when (A) is red or 43 or 4343 when (B) is red, the alarm sounds and does not count.

2 is a structure for preventing the entry and exit without being detected by the sensor.

By controlling the vehicle in the above way, even in narrow roads, both directions can be smoothly communicated, while securing a parking space, it does not interfere with traffic, and it can solve the inconvenience caused by the fixed one-way traffic on the back road.

As described above, the present invention includes a device for detecting the entry and exit of the vehicle on the access roads of both sides, and includes a signal light to signal whether or not the entry, the entrance and exit direction and the number of vehicles of the vehicle by the entry and exit detection device It is equipped with an intelligent traffic signal controller that analyzes the information about and connects to the traffic lights of both access roads, so that the road can travel smoothly without mutual correspondence on both sides of the road where only one vehicle can pass. The parking space can be secured without giving the traffic and the traffic on both sides can be fair and efficient without the inconvenience caused by the fixed one-way street.
