Traffic lights and traffic crossings are very common spots found in each & every corner. Due to the inability of the vision, visually impaired persons face the dilemma every day. With the integration of various techniques developed by the researchers, this complication can easily be rectified. The researchers have proposed system which infers the use of voice synthesizer with the wireless module. The blind navigator system uses the ultrasonic sensors for detecting obstacles and distance measurement of the obstacle. But these systems are not compatible according to the present scenarios as today’s world need direct application with good security and strident usability. The proposed system makes use of wireless module, ultrasonic sensors, voice synthesizers and audio system. The essence of the interface of these modules is easily available. The proposed system also amends all the limitations of the system used for the integration.
