How to use smart data to improve traffic safety? It works like a jigsaw puzzle: when assembled correctly, it provides a holistic and detailed view of the traffic situation. Whether it’s optimising traffic lights, traffic management, monitoring vehicle movements or weather, using data, digital technologies and machine learning brings major benefits for traffic safety, strengthening traffic infrastructure, as well as managing unexpected situations on the roads. Specifically, less congestion, less environmental burden or better prediction of driver behaviour. Thanks to data, we can react in time to dangerous situations such as slippery roads or traffic accidents, but also make better use of parking spaces. Interested in more?
