For this, 2 Modes are to be defined – Incognito (Auto) and Normal Mode.

Incognito Mode is basically the internal vehicle-horn system mode which enables vehicles to communicate internally using RF transceiver and internal buzzer-alert system that replaces the conventional honking system.

Normal Mode is the conventional honking system mode. When there is a human (obstacle) intervention or there is no receiver in range, then this mode is activated as to alert the surrounding which is essentially necessary to avoid accidents.

Therefore, the current invention transits between these 2 modes as per the circumstance demands.
Fig. 1 explains the overall control flow of the system to be integrated.
Initially, the transmitter generates a signal either of Type-1 or Type-2. The signal is divided considering the emergency situations. Type-1 corresponds to vehicles used by common people and Type-2 corresponds to ambulances and vehicles of higher dignitaries. Type-2 vehicles have got more preference than Type-1 vehicles as can be concluded from the fact that Type-2 vehicles are used for special purposes.
The next step is to direct the signal in the forward and partial sideway directions which is done by a suitable antenna. The purpose of doing this is to ensure the signal does not interfere with the vehicle at the back because horns are generally used to alert/overtake the vehicles In front.
Next the system detects whether or not any vehicle is present in range. If at least one vehicle is in range of the transmitter, then the Auto mode prevails else the system automatically changes to Normal mode which is just a precautious step.
Next, Human (Obstacle) intervention is checked. Now, if intervention is not present then the system retains it’s Auto mode else it transits to Normal mode to alert the obstacle and consequently avoid accidents.
This process is being done using image processing and infrared detection. Image processing can be helpful to detect human figures and other predefined obstacles in range. Infrared detector can be used to detect presence human/animal flesh present in range during the day and night as well. The integration of these 2 systems are firstly made to operate at Line of Sight, defining the range as required. This can assure us accuracy in detection over 24 hours, ultimately discarding the possibility of accidents.

Fig.2 explains the response system of the current concept. The vehicles at back and the vehicles that are not in range aren’t disturbed by the source signal. The vehicles that are in range and in the required orientation receives the signal and accordingly the response(s) is/are produced.
Moreover, as the system needs power to operate, so the vehicles which are not in their running state aren’t disturbed which is quite analogous to the current road-traffic system.
Fig.3 explains the signal preferences to be offered which is again analogous to the conventional system. Type-2 signals will be preferred over Type-1 signals.
Fig.4 describes the transition between Auto and Normal Mode as per required. Presence of human/obstacle in range of suitable detectors as discussed above decides the transition between the two modes that is to be set to meet the requirements.
Vehicles using the mechanical horn/bell system are to be provided with the receiver only to receive the signal of any other vehicle behind it. Mechanical horns/bells are retained owing to its property of no electrical power consumption and less noise pollution.
Traffic Guards are given portable receiver device to manage traffic efficiently.
The portable receiver to be provided can be made an ear-wear which will ensure smooth flow of the system. It can be provided to the drivers, which actually helps if compared to the conventional horn system. Many vehicles turns on loud music which distracts the driver’s concentration but an ear-wear will necessarily keep him/her focused.
Lastly, if in rare cases there happens to be any malfunction in the Auto mode circuit, then the system is likely to work on Normal mode which is acceptable. Breakdown of one system mode does not affect the other.
Thus, the current invention discards almost all of the possibilities of adverse circumstances justifying it’s superiority over the conventional vehicle-horn system.
