Abstract

This paper proposes a method for detecting frontal pedestrian crossings from image data obtained with a single camera as a travel aid for the visually challenged. This would be embedded on a pair of glasses, will be capable to detect the existence and location of a zebra crossing, to measure the wide of the road, and to detect the color of the traffic lights. The process of detecting a cross road is a done before followed by the process for detecting the state of the traffic lights (colors). It is important for the visually challenged (blind) to know whether or not a frontal area is meant for crossing. The existence of a cross road is detected in two steps. In the first step, edge of road is detected and pattern is detected are employed to identify the crossroad. In the second step, the existence of a crossroad is detected by checking the periodicity of white lines on the road using projective invariants technique. Then the traffic light detector is used to check the pedestrian light and the time in the display panel. The calculated time is then compared with the average time needed for a blind person to cross. The observations are conveyed through voice signals using the voice- vision technology. Thus, this effective technology aids vocational training for the visually impaired throughout the globe.

Abstract

The paper describes the design of an intelligent auto traffic signal control system. Traffic congestion is the major issues that would be considered. At the junctions of the road, vehicular traffic intersects and it can be controlled by the traffic signals. One of the main need of the traffic signal is that good coordination and control among the vehicles. The traffic on the road is very high during the peak hours. This leads to the emergency vehicles to stick in the traffic jam. Dynamic control of traffic is needed during peak hours. Hence we propose an automatic traffic light control for emergency vehicles. The traffic light in the path of any emergency vehicles is controlled. It does not depend on the way of monitoring people to be manual which results in time delay. So, Human life is not affected due to the time delay in the arrival emergency vehicles. To control the traffic, the man power is not required in this method. The emergency vehicles find the shortest path to the location of the accident. If the train crosses the junction, the emergency vehicle gets alerted before five km. In front of the   zebra line crossing, a divider can be created for safety crossing of people. The system uses AT mega 8micro controller, IR sensors. This system is used to control the traffic lights. And also save the time in emergency periods.
