A computer vision-based system for path finding and navigation aid could enhance the mobility of visually impaired as well as blind people to travel independently. In such a way that it identifies zebra-crossing lights in the surroundings as well as gives opinion about the present period of the crucial light. Because of the constrained resources of mobile devices extremely proficient and exact calculations must be produced to guarantee the unwavering quality and the intuitiveness of the framework. In this paper, a comprehensive survey has been done on zebra crossing, and traffic signals using Mobile Phone camera.
