IOT Based Smart Road Sign Alert System

Name of Project: IOT Based Smart Road Sign Alert System

Abstract:

The IoT Based Smart Road Sign Alert System is designed to improve road safety by providing drivers with timely alerts about important road signs and hazardous locations. The proposed system uses an Arduino-based IoT device integrated with GPS, LCD, buzzer, and an accelerometer to determine the vehicle’s location and provide alerts when the vehicle approaches a registered road sign or hazardous area. The detected road-sign information is displayed on an LCD installed inside the vehicle, while the buzzer provides an audio alert to notify the driver.

A web-based application is developed to manage and maintain road-sign information. The system provides separate access for the Administrator, Road Department/PWD, and RTO, allowing authorized users to add, view, update, and delete road-sign details such as sign name, description, address, latitude, and longitude. The web application uses HTML, CSS, and Bootstrap for the frontend, Java for the backend, and MySQL for database management. The embedded device is programmed using Embedded C.

The proposed system provides advance warnings to drivers about road signs and potentially hazardous road sections, helping to improve driver awareness and promote safer driving. By integrating GPS-based location detection, IoT hardware, a buzzer, LCD display, and a centralized web application, the system provides a practical and cost-effective approach to intelligent road safety.

Key Features of the IoT Based Smart Road Sign Alert System :

1. GPS-Based Location Detection

The system uses a GPS module to determine the vehicle’s current geographical position using latitude and longitude coordinates. These coordinates are compared with registered road-sign locations to identify nearby signs and trigger alerts.

2. Smart Road Sign Detection and Alert

The system stores road-sign details such as sign name, description, address, latitude, and longitude. Based on the vehicle’s GPS location, the system detects the relevant road sign and provides an alert to the driver.

3. LCD Display for Driver Information

An LCD display installed inside the vehicle provides clear visual information about detected road signs and upcoming road conditions.

4. Buzzer-Based Audio Alert

A buzzer provides an audible warning when a relevant road sign is detected, ensuring that the driver receives an immediate alert.

5. Web-Based Road Sign Management

A web-based application allows authorized users to add, view, update, and delete road-sign information. The system manages details such as sign name, location, latitude, longitude, and description.
