Accidents as seen through the lens of data
13:30 - 13:55 Technology and Data
- The typical data landscape around roads is multi-domain, multi-modal, complex, and inhomogeneous. Cameras, loops, computer vision algorithms, weather stations, connected vehicles and social media generate hundreds of millions of data points every single day.
- It is an impossible task for traffic controllers to grasp what's noise and what's actually insightful and actionable, let alone maintain good situational awareness in real-time.
- In this presentation, we will show you in detail how we use a combination of machine learning and expert system techniques to extract the best from each data sources and combine them optimally to remove noise.
- Using a few real examples on our road, we show how we piece together a comprehensive understanding of when and where accidents happen, as well as their real-time impact on the road.
