Abstract

The present invention relates to a safety system for preventing a collision on a Hi-Pass road. According to the present invention, a collision prevention unit installed in an each Hi-Pass road determines whether an unexpected situation occurs on the Hi-Pass road and displays a warning manufactured in advance by a smartphone navigation application and a display panel when the unexpected situation occurs. So, the safety system for preventing a collision on a Hi-pass road can effectively prevent a succeeding accident and traffic congestion due to the unexpected situation on the Hi-Pass road. Also, the safety system for preventing a collision on a Hi-pass road can remarkably reduce the succeeding collision accident in a weaving section by enabling a display device installed in a periphery of entry of the weaving section to display the warning when the unexpected situation occurs in the weaving section. A controller transmits entry error data to the collision prevention unit by immediately sensing the entry of a vehicle without Hi-Pass in case that the vehicle without the Hi-Pass enters the Hi-Pass road. The collision prevention unit displays the warning when receiving the entry error data from the controller. So, the safety system for preventing a collision on a Hi-pass road can effectively prevent the collision accident and the traffic congestion by preventing the entry to the Hi-Pass road (S2) in advance before the unexpected situation occurs.

Description

Safety system for preventing crush of hi-pass road}

The present invention relates to a high-pass lane collision prevention safety system, and more particularly, to prevent subsequent accidents by providing accident information to subsequent vehicles when detecting a sudden situation such as slowing, stopping, or crashing in a high-pass lane. At the same time, it relates to a high-pass lane collision avoidance safety system that can maximize traffic flow.

As the number of vehicles increased and the road expanded, the number of tollgates for fare settlement according to road driving also increased.

These toll gates are facilities installed at the entrance and exit of toll roads to collect and pay tolls. According to the toll collection method, 1) toll gates are used to pay tolls using high-pass terminals. 2) It is classified as an incentive settlement where toll payments are made through human resources, and usually a manned settlement and an unmanned settlement are mixed, that is, some of the lanes are operated as manned settlements and the remaining lanes are operated as unmanned settlements.

In general, a toll gate section includes a toll gate in which some lanes are installed with a mixture of unmanned oxygen and manned oxygen, a plurality of high pass lanes connected to the unmanned oxygen of the toll gate, and a plurality of general lanes connected to the manned oxygen of the toll gate. And a weaving section formed in front of the high pass lanes and the general lanes.

In addition, the unmanned clearing center is equipped with a high-pass payment system that collects tolls by connecting to the high-pass terminal, and the speed of the passing vehicle is higher than that of the general lane operated by the manned clearing station because the toll payment is automatically made without any operation. This can be done quickly to provide convenience to the driver.

However, in the conventional toll gate road, as the passing vehicle of the high pass lane travels at a speed of about 30 km / h to 100 km / h, a vehicle driver unknowingly stops unintentionally when a vehicle without a high pass or a vehicle with insufficient balance enters the toll gate. Or even get off the vehicle to cross the high-pass lane without permission, which leads to not only crash accidents of subsequent vehicles, but also life-saving accidents of unauthorized pedestrians. On the other hand, although the speed limit of the high-pass lane is suggested as 30km / h under the Road Traffic Act, more than 80% of vehicles driving the high-pass lane actually run without keeping the speed limit.

In other words, in the conventional toll gate road, the speed of the passing vehicle is relatively fast in the high pass lane, whereas a general vehicle without the high pass enters or a vehicle that runs out of the balance enters the high pass terminal. In addition to the frequent occurrence of variables, the occurrence of these variables consists of sudden stops and stops of passing vehicles. Therefore, collisions of the first and second vehicles of the following vehicles frequently occur due to sudden stops of the preceding vehicles. Have

In addition, since high-pass lanes are constructed to prohibit changing lanes by installing barriers and other structures on both sides of the lane from entry to exit, vehicles that have already entered the high-pass lane in the event of a crash cannot move to other lanes. This falling problem occurs.

On the other hand, in the conventional toll gate road, weaving sections are formed on the road ahead of the high-pass road and the general road for the driver to use the lane corresponding to the fare system suitable for them. There is a problem that frequently occurs collision due to excessive weaving of the vehicle.

Particularly, in the weaving section, since the flow of the vehicle is concentrated, many cases of the first accident occur in subsequent accidents such as secondary and tertiary, but conventionally, means and apparatus for recognizing the accident ahead of the vehicle ahead. Since it is not configured separately, it is not possible to prevent subsequent accidents in advance.

1 is a block diagram illustrating a high-pass lane stopping vehicle warning system disclosed in Korean Patent Registration No. 10-1087610 (name of the invention: high-pass lane stopping vehicle warning system and method).

The high-pass lane stopping vehicle warning system (hereinafter referred to as a prior art) 100 of FIG. 1 is located on the high-pass lane of the highway and is a circuit breaker motion detection unit 110 for detecting the operation of the blocking bar provided in the toll gate. A vehicle speed detection unit 120 for measuring the speed of the entry vehicle A entering the toll gate, a display unit 130 for displaying an alarm for a subsequent vehicle B following the entry vehicle A; When the entrance vehicle A enters the toll gate 10, a control unit for outputting an alarm signal to the subsequent vehicle B to the display unit 130 when the breaker is lowered or when the vehicle A suddenly decelerates ( 140).

The prior art 100 configured as described above proceeds continuously to the entry vehicle when the entrance bar entering the toll gate is decelerated due to inadvertent driving, or when the blocking bar is operated due to the high pass terminal not being attached. By displaying an alarm for the following vehicle, it is possible to prevent the collision between the entry vehicle and the subsequent vehicle in advance.

However, the prior art 100 has a disadvantage in that the efficiency of accident prevention is lowered because an alarm is generated after a vehicle collision or a speeding and slowing vehicle is sensed, that is, a warning is generated after a pre-occurrence.

For example, in order to prevent an accident due to a sudden stop of a vehicle without a high pass, it is efficient to recognize a warning when a vehicle without a high pass enters a high pass lane and output an alarm to a subsequent vehicle. Since the vehicle without the high pass stops by the breaker, and detects this and outputs an alarm, it cannot provide information to subsequent vehicles that have already entered the high pass lane.

In addition, since the prior art 100 is configured to output an alarm when a collision accident occurs only in a high-pass lane, it detects a sudden situation such as a slow vehicle or a collision accident in a weaving section in which weaving of the vehicle frequently occurs, or weaving section There is no technology and method to inform the following vehicles in advance about the accident situation in Esau, which not only reduces the effectiveness of accident prevention, but also has a structural limitation that does not reduce traffic congestion.

In addition, another problem of the present invention is that the controller immediately recognizes when the general vehicle enters the high-pass lane and transmits the entry error data to the collision avoidance unit, and the collision avoidance unit warns when receiving the entry error data from the controller. By displaying the phrases or providing information on the smart phone Nai app before entering the high-speed lane (S2) before the occurrence of the crash by blocking the high-pass lane to more effectively prevent accidents and congestion To provide a safety system.
