**GPS Signal Acquisition and Data Parsing**: Accurately acquire and parse GPS data to determine the vehicle's current location and speed. - **Vehicle Position and Speed Calculation**: Calculate precise vehicle position and speed in real-time to provide accurate data for communication. - **V2V Communication Establishment**: Establish a reliable communication link between vehicles using the LoRa module to transmit and receive data. - **Overtaking Intention Detection and Signal Transmission**: Detect overtaking intentions and transmit this information to nearby vehicles to alert them of potential hazards. - **Signal Reception and Processing by Nearby Vehicles**: Ensure nearby vehicles can receive and process overtaking signals to determine the position and speed of the overtaking vehicle. - **Driver Alert Generation**: Generate audio and visual alerts to inform drivers of the presence and intentions of nearby vehicles, especially during overtaking. - **Continuous Monitoring and Data Logging**: Continuously monitor the system's performance and log relevant data for analysis and future improvements. ## Project Details - **Owner:** pushpashanmugam -
