Complex traffic study in Netherlands

When carrying out a complex traffic study, it may be difficult to map the entire traffic situation, especially with traditional methods. Using a solution in form of traffic research from air with a drone and DataFromSky software, all movements are recorded down and analyzed to the smallest detail for unlimited data. In addition to junctions and road sections, the system is also suitable for parking areas, events, station environments or terminals.

The benefits of traffic research from the aerial video:

  • accurate data about traffic flow (counts), turning movements, speed, acceleration, travel time, stationary time (queing time) and many other traffic parameters
  • reliable, detailed research without influencing traffic behavior (inconspicuous solution)
  • full traffic research, almost without a human intervention
  • tool to improve traffic safety
  • perfect communication tool for organizations, citizens and politics



Simple insight into all data
The knowledge in form of a aerial video with exact traffic parameters, speed measurements and identification of inappropriate or dangerous behavior is a very powerful communication tool for organizations, citizens and politicians alike. Moreover, it is fairly easy to evaluate, or use the results immediately in programs for traffic simulation models such as VISSIM.

Our partner in the BENELUX region – Roelofs – has recently carried out such complex traffic analysis accross the Netherlands using the drones to analyse the crossroads – especially roundabouts and signalized intersections.

Speed-based trajectories in the analyzed area

The results obtained thanks to DataFromSky were further used to create a simulation model in VISSIM, using the real data about: vehicle categories, speed and acceleration in crossroad, intensities on each lane, vehicle gap time and origin destination statistics. This is the most accurate simulation you can achieve by using real world data! If you want to get more detailed information about the analysis results, click here .

    DataFromSky traffic analysis in United Arab Emirates

    DataFromSky has recently analyzed several traffic videos collected in United Arab Emirates, near cities of Dubai or Abu Dhabi. Output from one of these analysis may be seen below, or on our Vimeo channel. This analysis proves, that our system is adapted and capable of analyzing the videos in various weather conditions, including very dusty or sandy environment such the one in Emirates, as proven in the video.

    Moreover, in recent times, our team of DataFromSky is working on development of realtime UAV solution – drone analyzer, that will be able to provide accurate traffic data right off. The main objective is to design the cutting edge technology: an UAV based solution for the purpose of active traffic management over a road network. The solution will be capable of providing real time video monitoring and traffic data collection on the road, starting with the simple vehicle counting, monitoring of traffic density, actual speed and acceleration, up to the vehicle number plate recognition. One of the specific and useful feature will be possibility to identify near accidents and collisions (identify dangerous behaviour of road users, slow moving traffic, stopped vehicles, traffic jam etc.).

    Complete traffic analysis in Dalmine, Italy

    DataFromSky in cooperation with Trafficlab, conducted an important and complex traffic analysis in Italy, over the motorway junction of Dalmine (Bergamo), near the A4 motorway (Torino – Trieste), and the highway SS470. With the aid of a special balloon (Immagini al Volo) and DataFromSky, it was possible to obtain a complete picture of the performance of the vehicles during the morning peak hours (7.00 – 9.00).

    In particular, the studied elements are 4 junctions: 3 roundabout and 1 multi-level junction, directly connected to the motorway.

    Through the traffic flows obtained, it was possible to create an OD-matrix for every junction and for every type of vehicle (bicycles, motorcycles, cars, medium vehicles, high vehicles, buses), to extrapolate information about the behaviour of every vehicle, such as acceleration, speed, time gap, time to follow; all these data are available for every route and every type of vehicle. The acceleration and the maximum and minimum speed values represent a valid help for the creation of a traffic simulation on the junction that were considered. The results are great with a minimum difference between the number of entering vehicles and the number of exiting vehicles (it has to be considered that the surveys were conducted in different times and days).

    Another peculiarity of this tool is to give the possibility to elaborate vehicle’s trajectories with a GIS software. The trajectories are connected to a geo-database that contains all the information about the vehicle and its behaviour (shape files).

    It is interesting to focus on the incorrect behaviour of road users with the help of the object presence alert, the new special feature of DataFromSky Viewer. For example, it was possible to see that a vehicle crossed the roundabout in the opposite direction!

    Finally, thanks to an in-depth analysis of the Copert model about pollutant emissions, it was possible to define the quantities of pollutants released into the atmosphere by the traffic flow of the considered area: CO [kg], Non methane VOC – HC [kg], PM [kg], NOx [kg], CO2[kg] e Fuel Consumption [kg].

  • Multilevel intersection – no problem for DataFromSky

    We never rested on our laurels! Our tool for trajectory interpretation DataFromSky Viewer is being constantly evolved and now comes with few new functionalities!

    Multilevel intersection detection
    DataFromSky can track vehicles in multilevel roads! As the video shows, we can track all the vehicles even when the visual occlusion appears. DataFromSky can follow the whole trajectory of the car for the tracked time and collect reliable data – average speed, acceleration, gap-time, time to follow, heatmaps or dimensions of vehicles.

    Stationary time
    Since now, we are able to count the time, for which is the vehicle in a stationary position, in other words, how long the vehicle has to wait until it passes some obstacle (intersection, traffic lights, traffic jam etc.). This figure may help to determine the utilization and load of a traffic junction.

    Video parameters:
    Hight: 81 m, top-down view
    Tool: drone
    Place: multilevel intersection, Kato Varibobi – Greece

    Take a look at the video below, demonstrating new useful functionalities of DataFromSky!

    Transforming aerial video data into knowledge

    DataFromSky is a unique solution for motion analysis of aerial video data. The ability to detect, track and classify moving objects from aerial videos provided by drones, fixed cameras or other video sources opens new possibilities in the field of traffic monitoring. The technology behind is under intensive development and grows more efficient every day through the embedded capability of learning from its mistakes. We are happy to announce that we have made a significant step towards enhanced accuracy thanks to the complex integration of deep neural networks into DataFromSky framework. Our deep neural networks are being trained on millions of samples 24 hours a day. The quality is quite impressive right now!

    Our tool for trajectory interpretation DataFromSky Viewer also comes with a new functionality. The new version extracts parameters which are sometimes difficult to obtain, such as gap-time, time to follow, heatmaps, and dimensions of vehicles. We recognize the potential of the data we are able to obtain, and, therefore, co-work on our tools with traffic researchers and traffic engineers worldwide. The video below demonstrates the new functionality of DataFromSky Viewer. Take a look!
