Abstract: Nowadays traffic congestion in the urban areas is becoming very difficult due to enormous increase of automobiles. So in order to rectify this problem we presented a nice way to regulate the vehicles in crowd and a junction area, which eliminates the involvement of humans in its operation. Traditional traffic signal system only gives instructions to stop. However, if someone is breaking the signal then this system is not able to catch them and there are chances of taking bribe. Therefore, to increase the security of traffic signal, to reduce human efforts, and to avoid the bribery we are introducing smart traffic signal system through this project. Smart traffic signal based on the Arduino & infrared sensor, in which infrared sensors are placed at one side of road in such a way so as to cover particular necessary area of road from where the vehicles are waiting in the signal. Then it compares the density of the all the four tracks and it gives green signal to which track have a more density of vehicles. If all the track has same density, then normal flow of signal is maintained. If the signal is red and any vehicle breaks the signal, then the infrared sensor detects it and Arduino microcontroller take immediately action to buzzer alarm to warn the vehicles which cross the signal line mark. In addition , another feature is implemented called “Punishing Signal”. It uses special decibel meters connected to traffic signals across the city. When the decibel exceeded a 85dB, the signal timer would reset itself, forcing the people to wait longer at the signal. This is meant to ‘punish’ them for their impatience with the message that if they honk more; they will have to wait longer. “Honking is a bad habit and an act of traffic indiscipline. Unfortunately, many of them indulge in reckless honking. Honking causes noise pollution, hurts the eardrums, increases heart rate, creates traffic confusion and causes stress, that system have reduce the noise pollution and the avoiding the human error in the signal changing and reduce or control the traffic jumping at the time of red signal is displayed.
