AUTOMATIC SPEED VARIATION SYSTEM IN AUTOMOBILE LINKED WITH DOORS
The sudden accidents often occur when passengers traveling on the footpath of public transport at high speed. The sudden fall from footsteps at that speed may cause serious risk to passengers. In this paper, we present a passengers safety system that has two major features, one is to detect the passengers present in the footpath of the vehicle and the other one is to maintain the speed of the vehicle based on the detection of passengers in the footpath. The present work used IOT system that contains an ultrasonic sensor to detect passengers in a given area. Based on the sensor output of detection of passengers, the door of public transport will automatically open/close and also it will maintain or increase the speed of the bus based on the results. The development of this IOT system also implements an IEEE 802.11 technology to transmit the signal from public transport to mobile apps. The monitoring and controlling mobile application are developed which can receive/transmit the data from/to the controller of the system by using IEEE 802.11. This mobile application shows the status of detection of passengers, door status, and also the real-time speed of the public transport.
