Inspiration
Road accidents often turn fatal not because of the collision itself, but because emergency help does not arrive in time. In many real-life scenarios, victims may be unconscious or unable to call for help, leading to critical delays. This problem inspired us to think about how technology—especially AI—could automatically step in during such moments and ensure that help is requested immediately without relying on human intervention.
What it does
ACCISENSE is an AI-driven accident detection and emergency ambulance dispatch system that works automatically in the background. When an accident occurs, vehicle-related data representing airbag deployment, sudden speed drop, braking intensity, and impact conditions is analyzed using machine learning. The system classifies the accident as minor, moderate, or severe. While minor accidents are ignored, moderate and severe cases automatically trigger an SOS alert with precise location details to help dispatch the nearest ambulance or notify nearby hospitals.
How we built it
We built ACCISENSE as a software-based system to keep it scalable and hackathon-friendly. Accident-like vehicle and OBD data were simulated and preprocessed to remove noise and extract meaningful features. A machine learning model was trained to classify accident severity, and decision logic was applied to trigger emergency actions only when required. Location-based logic was then used to identify the nearest ambulance services, and the entire workflow was designed to run automatically without manual input.
Challenges we ran into
One of the main challenges was realistically simulating real-world accident scenarios without access to actual vehicle hardware or sensors. Another challenge was finding the right balance between sensitivity and accuracy—ensuring that serious accidents are detected while avoiding false alerts that could cause unnecessary emergency responses. Designing a system that is both technically reliable and easy to explain was also a key challenge.
Accomplishments that we're proud of
We successfully designed an end-to-end AI-based emergency response system that works fully automatically and demonstrates real-world relevance. Building a complete pipeline—from data simulation and preprocessing to severity classification and ambulance dispatch—was a major achievement. We are especially proud of creating a solution that focuses on saving lives, not just technical complexity.
What we learned
Through this project, we learned how machine learning can be applied to real-world safety problems, how to handle noisy and imperfect data, and how to design decision-making systems that must be reliable and fast. We also gained valuable experience in building solutions that are human-centered, scalable, and suitable for real-world deployment.
What's next for ACCISENSE
In the future, ACCISENSE can be extended by integrating real vehicle sensors, airbag signals, and OBD-II data instead of simulated inputs. Additional features such as smart traffic signal coordination, real-time hospital availability, and mobile app integration for emergency responders can further enhance the system. Our long-term vision is to make LifePulse AI a part of smart transportation and smart city ecosystems, where technology actively works to protect human life.
