Introduction: In Sri Lanka, combating drunk driving remains a critical challenge for law enforcement agencies, with traditional penalty systems often facing limitations in efficiency and accuracy. To address this issue and enhance road safety, the development of a Smart DUI Penalty System leveraging IoT technology and a mobile application offers a modern and effective solution. This system integrates an IoT device with alcohol detection capabilities and a React Native mobile application for streamlined penalty enforcement processes. By enabling police officers to quickly access driver information via QR code scanning and record penalties in real-time, this system aims to deter drunk driving and improve overall traffic safety.

Overview: The Smart DUI Penalty System comprises two components: an IoT device equipped with an alcohol detection unit and a React Native mobile application. When a police officer apprehends a driver suspected of drunk driving, they scan the driver's license QR code using the mobile application to retrieve pertinent information such as the driver's name, ID, previous violations, and address. The mobile application features a penalty list where the officer can select the appropriate penalty, including the option for a DUI penalty. If the DUI penalty is selected, the officer can input the driver's blood alcohol percentage. Upon submitting the penalty details, the data is automatically stored in a Firebase database for future reference and analysis.

Key Features:

1. Alcohol Detection Unit: The IoT device integrated with an alcohol detection unit enables police officers to quickly assess whether a driver is under the influence of alcohol, enhancing the accuracy of penalty enforcement.

2. QR Code Scanning: The React Native mobile application allows police officers to scan the QR code on a driver's license to retrieve relevant information, streamlining the process of identifying and recording driver details.

3. Real-time Penalty Recording: Police officers can select and record penalties in real-time using the mobile application, ensuring timely enforcement and documentation of traffic violations.

4. DUI Penalty Option: The mobile application includes a specific penalty option for drunk driving offenses, allowing officers to input the driver's blood alcohol percentage for accurate penalty assessment.

5. Data Storage and Analysis: Penalty data recorded via the mobile application is securely stored in a Firebase database, enabling law enforcement agencies to analyze trends, monitor enforcement efforts, and assess the effectiveness of DUI prevention measures.

Benefits and Impact:

1. Enhanced DUI Enforcement: The Smart DUI Penalty System provides law enforcement officers with the tools to accurately identify and penalize drunk drivers, contributing to a safer road environment and reducing the incidence of alcohol-related accidents.

2. Streamlined Penalty Enforcement: By digitizing penalty recording processes, the mobile application simplifies administrative tasks for police officers, allowing for more efficient enforcement of traffic regulations.

3. Improved Data Management: The centralized Firebase database facilitates secure storage and retrieval of penalty data, enabling law enforcement agencies to maintain comprehensive records and conduct data-driven analysis.

4. Deterrence Effect: The visible deployment of IoT devices and the efficient enforcement of penalties serve as a deterrent to potential offenders, discouraging reckless driving behavior and promoting compliance with traffic laws.

5. Public Safety: By leveraging technology to combat drunk driving, the Smart DUI Penalty System contributes to the broader goal of ensuring public safety and reducing the incidence of traffic accidents and fatalities.

Conclusion: The Smart DUI Penalty System represents a significant advancement in traffic enforcement technology, offering a comprehensive solution for combating drunk driving and promoting road safety. By integrating IoT devices with alcohol detection capabilities and a mobile application for penalty enforcement, this system empowers law enforcement officers to effectively enforce DUI regulations and hold offenders accountable. As Sri Lanka continues its efforts to improve traffic safety, solutions like the Smart DUI Penalty System play a crucial role in creating a safer and more responsible driving culture.
