On January 10-11, Transportforum – the Nordic region’s largest annual conference within the transport sector, will be held in Linköping, Sweden. At the conference, researchers and stakeholders meet for knowledge sharing and benchmarking.
COWI, our partner in the Nordic countries, will be present with a stand (number 28) and give several lectures. On Wednesday January 10 at 15:30-17:00 Mathias Sdun, Chief Specialist at COWI, will talk about risks associated with bus stops based on analyses conducted using DataFromSky (read our recent article). Mathias will also explain how DataFromSky analysis can give us detailed information about road user’s behavior before some accidents really happen and thus give us the possibility to act preventively.

DataFromSky has participarted in PTV’s periodic event – Traffic Innovation Workshop, held on 26. 10. 2017 in Dubai, UAE! Thanks to our regional Business partner in the Middle East, the capabilities and great progress of DataFromSky system was demonstrated during this event, which is a good opportunity to bring together transportation professionals and ITS providers from public authorities, consultancies and academics.
We are pleased, that our solution have attracted many participants of the event and that we have met with a very positive feedback!
New research paper called “How accurate are small drones for measuring microscopic traffic parameters?” published in Transportation Letters Journal can provide an answer. Adam Babinec, one of the main IT developers standing behind DataFromSky solution, co-author of the article conducted by University of Athens and Brno University of Technology, says:
„With this paper, we wanted to examine the potential of using sUAV as part of the ITS infrastructure as a way of extracting naturalistic trajectory data from aerial video footage from a low volume intersection and a pedestrian passage. Moreover, we have examined the accuracy of speed data collected from a drone compared to data collected from an On-Board Diagnostics II (OBD-II) device.”
The results show, that the distortion correction and calibration phase of the video are of crucial importance for high level of accuracy, in terms of stabilizing and geo-referencing the video. In order to extract accurate data from drone video footage, each aerial video must be stabilized to compensate for camera movement, since sudden vibrations or small wind gusts can lead to large errors on the ground.

The accuracy of DataFromSky system itself was examined in another research paper, created in collaboration with Faculty of Information Technology and Faculty of Civil Engineering at Brno University of Technology and posted in International Journal of Transportation Science and Technology, for more information click here.
DataFromSky introduces new way how to record video to obtain high-quality data for advanced traffic analysis. New, specially developed balloon for accurate data collection brings many advantages, including:
Fixed long-term monitoring (usable in persistant traffic monitoring, perimeter security)
Up to 3 hours of operating time
Transmits data in HD resolution
Stabilized optical system – 4k image resolution
Maximal reachable altitude: 200 meteres
Covered area: up to 300 000 sq.m. (from max. altitude)
Fast deployment: in 25 minutes
Space saving, easy transportable
The camera is attached to a balloon inflated with gas – 3m3 of helium. This solution is very good alternative in cases, where using a drone is limited and too difficult to get authorizations. One of the biggest benefit of recording the video with the balloon is the time, for which it can be in the operating mode. Compared to standard drones, which often lasts in the air only 25 to 40 minutes, this balloon is able to hover over the intersection / traffic node for up to 3 hours and thus can provide very informative and interesting data. In this way one can have a wider vision that allows to report potentially critical situations and to find out how to solve them.

We are happy to announce that we have succeeded with our proposed project and get supported in Programme Epsilon 2 conducted by Technological Agency of Czech Republic:
System for Preemptive Safety Analysis of Road Network Nodes and Traffic Flow
The aim of the project is development of a preemptive quantitative system for analysis of road network nodes in terms of safety. The system will be
based on analysis of time-space information about each individual traffic member. The information will be automatically extracted with high precision
and frequency from video data collected by UAVs. The trajectory data extracted from video will be analyzed in terms of traffic safety, based on
detection of non-standard and aggressive behaviour, conflict situations, incomfort during passage etc.
ACM SPY (Czech ACM Chapter & Slovakia ACM Chapter Student Project of the Year) is an official competition of high-prestige Czech and Slovak universities for the best master’s thesis in IT area.
One of our talented colleagues, Adam Babinec, was just chosen as one of TOP finalists in 2015 with DataFromSky thesis called: Traffic monitoring from aerial video data, and we would like to congratulate him! Keep fingers crossed for us in the announcement of final results.
As Denmark has become first country in the world using real-time traffic data all around the country we got the opportunity to analyse one of many busy crossroads in there. For us it is the second time monitoring traffic in Denmark, this time in Rismarksvej. The intersection is four-way and bicycles friendly and controlled by traffic lights.
Length of analyzed video: 11 minutes
Number of objects being tracked: 525 (vehicles and bicycles)
Total distance traveled: 89 044.4 metres
Average speed: 11.104 km per hour
The exact location is:
And we would like to thank to RAMBOLL for providing us a video.
Alan Sackrin, Florida based Civil Trial Lawyer, published an article about the importance of road design and its influence on road crash statistics.
Current conditions of roadways and their design – these two factors play a major role in number of car accidents.
There are times when people are seriously injured or even killed in auto accidents on a traffic path where the design itself causes danger mentions Alan Sackrin.

Transportation is one of global issues and the road traffic accidents death rate is annually increasing. DataFromSky wants to fight against this problem by providing advanced safety analysis. Join us to keep our roads well-designed and safe!
Mike On Traffic is a blog about “the Less Boring Side of Traffic Engineering“. DataFromSky was recently mentioned in a post called Counting Cars from the Sky: The Future of Traffic Monitoring.
