Implementation of Vehicle to Vehicle Horn System


In this project proposed a Vehicle to Vehicle horn system. It can be accomplished by RF module. RF transmitter which is used to transmit the signal from one vehicle to another vehicle and RF receivers are inserted behind the car to receive the corresponding transmitted signal from the other vehicles. A buzzer and LED is used to alert the driver and a LCD is used to show from where the transmitted signal has been come .The whole functions of the system are processed by ardunio.

The goal of this work to reduce unnecessary vehicle horn. This system can be used as a substitution of horn system in the horn probhited area.


The major cause for the noise pollution is causes by the unwanted vehicle horn. The world is advancing at a rapid pace with the advent of technology and it becoming a part of pollution will adversely affect the present generation and many more to come, including us. The noise pollution is now a major concern in urban areas, unsurprisingly having numerous hazards.

The crux of noise pollution lies in the trinity of vehicular, railway and air traffic noises. Starting off with vehicular traffic, honking happens to be an integral part of it. Notably, vehicular traffic and honking noises contribute to 55% of the total urban noise. Due to the sizable increase in the number of vehicles, the widespread expansion Honking is a common occurrence in irrespective and conditions. The intention behind using a horn is to alert.

However, an unwanted use of the horn makes shake up or negatively affect active drivers and passengers of surrounding vehicles, pedestrians in that area.

If the sound level is greater than 120 dB, it has been found out that it may result in undesirable diseases like Hypertension and Insomnia. Certain aspects of the driving mindset such as impatience, anxiety, over accelerating, sudden braking, abiding traffic rules may also aggravate unnecessary honking. The objective of the study is to assess and quantify traffic noise, and the impact of honking on the urban environment. Further on, we will evaluate the available methods and identify their efficiency in reducing noise pollution through honking


Bluetooth communication: Limited range of Bluetooth module makes it useful for transmitting data over short distances, it will have limitations when the distance between the vehicles is beyond 100 meters. High Beam Headlights: This solution reduces noise pollution through honking as only lights are used. The limiting implementation of this solution is the constraint of night time. Infrared communication: The variation in sizes of vehicles may not allow sensors to work because Infrared sensors work in the line of sight and the vehicles on the road might not be always traveling in a straight line for desired sensor communication. Proximity sensor: It is affected by the temperature and humidity. The accuracy level is less and difficult to design.


In this study proposes vehicle to vehicle horn system has been accomplished using radio frequency module without using horn. RF transmitter which is used to transmit the signal to another vehicles and RF receivers are inserted behind the car to receive the corresponding transmitted signal from the other vehicles. A buzzer and LED is used to alert the driver and a LCD is used to show from where the transmitted signal has been come and the driver will decide where the car should be moved. The whole functions of the system are process by the Arduino. The goal of this system to reduce unnecessary vehicle horn.


This new system uses radio frequencies (RF) to communicate the horn signal between two cars. It involves fitting all vehicles with RF trans- receivers for a Green Horn ready ecosystem. These trans-receivers are to be mounted on the exterior body of the car. Now let us consider various possible scenarios, wherein a driver would require blowing a horn. All receivers are connected to a special buzzer and LED indicator that is fitted inside the automobile to which the receiver is connected. On receiving this signal, the buzzer will blow and the sound will only be heard inside the vehicles, ensuring a reduction in noise pollution. Since a receiver is mounted right adjacent to the transmitter, the horn will also be heard inside the car blowing the horn.


We conclude that this proposed system, will significantly help in reducing the noise pollution. This is with regards to the noise caused due to the honking of vehicles to a great extent without compromising the safety of people. Most importantly, the proposed system is practically feasible as well as implementable, and its cost will be reduced in mass production. RF frequency intensity calculations will result in the generation of an alert in all cars within the range of the transmitter.
