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.
