Design of an IoT-Based Traffic Management System for Smart Roads

Abstract

The primary objective of this design is to prevent traffic accidents. The great deal of research strongly indicated that the most of incidents happen in specific locations, such as school zones, restaurants, and so on. The proposed system's design is to avoid accidents in nearby areas by alerting or warning via Wi-Fi. A mobile notification is transmitted through the Wi-Fi link if the zone is fewer than 110 yards from wagon. In reply to this warning, the motorist slows the wagon's speed. A Wireless Fidelity warning will be sent to a cell phone if a school region is within 110 yards of it. After receiving alert from the Wireless Fidelity range to the driver's notification, the vehicle's speed is reduced. It provides message warnings to mobile devices within 100 metres of a Wi-Fi hotspot, as well as changes in weather parameters. The driver slows the vehicle's speed in response to this command. This sign contributes to a reduction in traffic based accidents. This system's controlled power supply uses 5V and 500mA, three voltage terminal regulators (7805) were utilised for voltage power and A full-wave bridge rectifier is used to rectify the 230/12V transformer secondary ac output. We have used Wi-Fi AT89S52 switches and a Wireless Fidelity module to connect the controller to the Internet of Things, allowing it to be operated from anywhere through IoT.
