Need to perform operational analysis of a roundabout based on the real traffic data? DataFromSky supports the calculation of a wide range of operational parameters such as critical-gap time / follow-up time / critical headway etc. Get super accurate traffic data for your research and/or traffic study regardless of the type of intersection using DataFromSky.
Monitoring and analyzing traffic behavior at intersections and roundabouts is an important task in the present traffic research. Trajectory analysis provides higher-level situational awareness by understanding the behavior of every traffic element in the analyzed scene due to the rich information contained in its own motion. DataFromSky is able to extract trajectories and their spatial-temporal statistical characteristics automatically with very high accuracy and high sampling frequency. Accurate traffic data is essential in any modern research in the field of traffic analysis such as:
Motion pattern classification, Abnormal motion pattern detection,
Traffic mining, Prediction of non-recurrent short-term traffic patterns,
Developing next-generation driving behavior models, Trajectory clustering,
New perspective on merging behavior – gap seeking instead of acceptance behavior,
Evaluation of traffic simulation methods / models on real data, Capacity estimations,
Traffic congestion studies, Travel-time, Vehicle counting, Trajectory based analysis,
Road safety, Pedestrian and cyclist safety, Road-user interactions, Smart analysis,
Driver decision making and complex multi-actor interactions, Traffic instabilities,
Empirical evidence of multi-anticipation (drivers have multiple leaders),
Study of behavior adaptation effect.
An unexpected end of the trajectories – DFS Light detected a traffic accident! Take a look at the video below.

We are proud to announce that we have connected DataFromSky with a simulation model VISSIM! PTV Vissim is a microscopic multi-modal traffic flow simulation software package developed by PTV Group, first developed in 1992 and nowadays, Vissim is a global market leader in microscopic simulation models! The simulation displays all road users and their interactions in one model.
We have created a promo video demonstrating how to export the results from DataFromSky and use it as an input in Vissim. This possibility opens so many opportunities how to utilize the real data from DataFromSky analysis and how to increase the accuracy of your simulation model!
What kind of data can be exported and what are the plans for further interconnection?
– traffic counts
– vehicle category (number of cars, heavy vehicles, buses, motorcycles etc.)
– turning movements – route decisions and routes
– speeds for model calibration
– travel times (between two defined gates)
– headways between two vehicles following each other (gap in seconds) – advanced gap analysis and headways data provided only by DataFromSky!
– queue lengths (will be added)
The video plays also the role of the very first User manual video of DataFromSky Viewer – it describes the process of creating counting gates in order to export the Origin-destination data and import them into Vissim. Other short instructional videos will follow soon!
Enjoy the video:
Another great project has been accomplished, among other things, thanks to DataFromSky analysis! DataFromSky has made a traffic study of a corridor in the city of Fairfield in Connecticut, U.S.. The data were used for an extensive Safety analysis of the whole corridor called Black Rock Turnpike. The study, created by The Connecticut Metropolitan Council of Governments (MetroCOG) and FHI, identifies strategies to create a safe and attractive pedestrian environment, a robust infrastructure for bicyclists, and linkages between residential areas and the shops, businesses and restaurants along Black Rock Turnpike.
Black Rock Turnpike is a major arterial that serves one of the city’s largest business and commercial districts. According to the estimates, approximately 20,000 vehicles utilize this corridor every day. As the results of the analysis show – although Black Rock Turnpike has a posted speed limit of 50 km/h (30 miles/h), the average speeds are between 55 – 65 km/h (35-40 miles/h). The road widths, speed, high traffic volume and numerous curb cuts create an unsafe and uninviting pedestrian environment. Click on this link to read more about the whole project.
However, what is truly remarkable about this analysis is the method how the data were recorded and analyzed. To be able to cover the whole corridor, which is roughly 1,3 km in length, up to 8 drones recording at the same time were needed! This allowed us to analyze the corridor as a complex scene, obtain the complete trajectories of vehicles for the whole analyzed route and create the detailed Origin-destination statistics! What were the key conditions for the successful analysis?
- top-down view position (bird’s eye perspective)
- space overlap – at least 10 % of overlap in the analyzed area from each side
- time overlap – all the drones started filming at the exact same time
Take a look at the video of raw output of 8 drone videos merged together:
Welcome to the new year 2018!
We will start this year with a slight look into the recent past. Lately, we have announced our great success in a start-up contest called “Connect Visions to Solutions”, organized by German-Czech Chamber of Industry and Commerce, which was held in Prague in late November. Have a look at the short video of this great event.
New traffic analysis from Mexico city.
The visualization video is showing capabilities of DataFromSky in very high traffic flow, where the density reaches 9 000 vehicles per hour!
Video displays IDs and categories of tracked objects (car, medium and heavy vehicle, bus, motocycle), current speed and acceleration, stationary time, traffic counting through gates, trajectories visualization and heatmaps based on average speed and acceleration.
DataFromSky in cooperation with COWI is coming with a new traffic analysis from Denmark! As in all other major cities, massive amounts of traffic goes in and out of Copenhagen every day. This leads to congestion and the everlasting discussion on how to effectively move as many people as possible. In Copenhagen, almost 50 percent of all commuting trips are made using bicycles. This results in numerous potential conflicts between bicycles and cars, and the battle for allocating and distributing sheer road surface space between the transport modes is continually on – especially at certain locations, where available space is scarce. One such place is “Christmas Moellers Plads”, an intersection complex connecting inner Copenhagen to the island Amager. Through the use of a specialized UAV and Data From Sky, COWI has obtained a complete 4-hour overview of traffic passing through this complex for both cyclists and motorists – and the interaction between the two. The data extracted now forms the basis for looking into new and better solutions that will keep this people mover perform at its best.
COWI, an exclusive partner in Denmark and other Nordic countries, nicely demonstrates the possibilities of DataFromSky solution in a new video. In this video, you can see some basic outputs from DataFromSky Viewer such as speed & acceleration data, heatmaps, vehicle types etc. We have an endless list of functions that can be added or improved, so expect more to come!
All commercial use of DataFromSky in the Nordic countries is handled by COWI, and key personnel can be contacted directly:
We would like to announce a new great feature – reports that can be opened in the most widespread spreadsheet editor of all time (so far). Yes, Viewer can now export a complete Excel sheet listing all the possible things you want to know, starting with turning movements and ending with with an image of the annotations. If you do not use Excel, no reason to be sad – the reports are completely readable in LibreOffice, too, and probably in most other spreadsheet editors.
As an example, here is a video from EXPO Milano. Not exactly from the exhibition though, rather from a nearby roundabout during afternoon. This is another video shot from a building, this time at a very poor angle – one of the legs is completely hidden. You can see easily that the roundabout is severely congested in the first few minutes of video. Looks like an overhaul might be needed…
The video included here is a short example, the total recording includes over sixteen hundred vehicles. Anyway, you are invited to take a look at what an excel report from such a place looks like:
