DataFromSky can detect traffic accidents before they happen!

Safety is one of the most important aspects of the traffic industry. Many serious traffic incidents happen on the roads worldwide every day. Thanks to the huge amount of traffic information gathered by DataFromSky aerial video analysis we are able to detect near-crash events, traffic conflicts, that statistically occur more frequently than real traffic accidents. By using this proactive approach that focuses on analyzing dangerous traffic situations that can but not necessarily have to lead to a traffic accident it is possible to detect:

– aggressive driver behavior
– offensive lane changing
– short following distances
– collision-prone traffic hub areas

So far, we have implemented some of the standard safety indicators like Time To Collision (TTC), Time Exposed Time To Collision (TET), Time Integrated Time To Collision (TIT) and Post-Encroachment Time (PET) which are used to detect traffic conflicts in spatial-temporal data obtained by DataFromSky aerial video analysis. The standard evaluation of some of these indicators was extended by road users movement prediction that better reflects their behavior and achieves better results. All of the detected traffic conflicts are properly visualized in DataFromSky Viewer where they can be interactively analyzed.

More features regarding the Traffic Safety analysis are coming. The project of Traffic Safety Analysis is jointly developed with the Faculty of Civil Engineering BUT and is supported by Technological Agency of Czech Republic.

Planned features

Bounding boxes mockup

We wish to share a couple of interesting features that will be coming to DataFromSky soon. Currently, DataFromSky understands vehicles only as points. This is an outcome of using the particular technology which we chose. However, this results in one very important drawback: We can’t tell real distance between vehicles. Incidentally, we hope for many applications, which would need precise measurement of distances starting from the actual metal, not an ideal point. After this introduction, it should come as no surprise that we are working on detection of vehicle bounding boxes. This will enable much better distance measurement for safety evaluations.

Another improvement in the pipeline is addition of anonymization functions. As you can imagine, aerial recording in urban areas results in a lot of areas being exposed, while they are assumed to be hidden from sight. To protect privacy, DataFromSky will allow marking of areas for blurring or blanking.

We hope to add this soon, so stay tuned for new versions!
