Abstract

Objectives: To propose a novel technique to halt vehicles at the signals before the stop line of a zebra crossing and allow pedestrians to cross the road safely. Methods: An advanced automated signal controlling system is developed using a controller, various sensors, and devices. The bollards are one of the important parts of our advanced automated signal controlling system. It is used to halt vehicles before the stop line of zebra crossing. The bollards are raised during the red signal phase and are lowered during the green signal phase. Different sensors such as rain sensor and RFID are used in the proposed model. The rain sensor is used to detect rain and allows the lowering of all the bollards, so that two-wheeler passengers can take shelter nearby. RFID tag and reader is used to detect the emergency vehicle and lower the bollards of the lane such that emergency vehicles can pass through. Findings: During the red-light phase, the bollard is raised up in the lane which allows pedestrians to cross the road safely. During the green light phase, the bollard is lowered down in the lane allowing vehicular movement. The use of bollards with the various sensors makes sure the pedestrians cross the road safely. The RFID tag can be used to lower the bollard of the lane for emergency vehicles like Ambulance, Fire brigade etc. Novelty: The array of bollards used in the work provide safety to pedestrians while crossing the road. The bollards are controlled by the ESP32 during the red and green phase. The method used is novel and can be used for implementing in smart cities.
