If people could not see colours, then how would traffic light work. This question is a common query for most of the people who want to contribute society by trying to help blind people. We see that in most of the cases of colour blindness people are prone with not being able to see red and green colour. The design of the traffic system is as follows ::
This new design is according to my opinion which is quite helpful for the colour blind people to detect the traffic lights. This is completely sensor and sound based system. The system consists of wireless audio plug that is to be connected in ears of the person who is colour blind. This wireless audio plug consists of sensors which detect the presence and colour of light. We already are aware of some types of light - based sensors which work in presence of specific type of lights. The most common being the LDR (Light Dependent Resistor) Sensor which works only when it comes in contact with light. A similar type of sensor can be used to detect the colour of light. The audio plug should also have a speaker and in built sound for three colours similar like (Traffic light is '____') where the colour can be programmed. When this sensor detects the colour then it should produce sound like the above statement. On hearing to this sound the person will get aware that what the traffic signal is and he/she can get aware regarding the same. This idea is for the ones who aren't able to see any specific colours.
