DataFromSky Aerial analysis in the Netherlands

ROELOFS, an exclusive partner of DataFromSky in the Netherlands, carried out comprehensive traffic research of a traffic node in the province of Gelderland. The data collected with a drone and analyzed by DataFromSky Aerial platform will be used as the main source for a study for planned major maintenance in 2021.

The drone was deployed at the roundabout of the N318 Misterweg in Winterswijk. When preparing for the major maintenance of this road, it is also being examined whether road safety can be improved. Besides other things, DataFromSky offers many great features for analysis of traffic behavior and road safety, including analysis of risky situations or near collisions, calculation of Time to Collision, Heavy Breaking and analysis of many other factors.
For many years, the data were collected by people standing on the side and observing the traffic, then the data were evaluated manually. This process was lengthy, inefficient, and had low-precision data output. All of these shortcomings are overtaken with a new modern approach combining 2 great technologies of today world: drones and AI.

DataFromSKI? Yes, we can count skiers too!

We have moved from the Sky to the Ski!
With our newly released DataFromSky Light, we are testing the software in unusual conditions and scenarios. Counting how many skiers are on the slopes? Not a problem at all. With our software, one can easily analyze how many people are currently on the slope, how many are waiting by the ski lifts, how many of them just stopped by a ski bar or restaurant or who is skiing outside marked slopes and much more!

You still have a chance to try the software on your own video, free of charge. It could be another atypical record, but keep in mind the recommended parameters for the input video (to achieve the best results with the highest accuracy):

  • resolution: 1280×720 or more (min. PAL)
  • bitrate: 5 Mb/s or more
  • framerate: 25 or more
  • min. traffic object size: 32px in one dimension
  • continuous video without cuts
  • no camera movement
  • Upload your video to WeTransfer and send it to analyze@datafromsky.com – if you need more information, follow the instructions in this post.

    How advanced image analysis is contributing to optimize urban mobility?

    A very good summarizing article about the capabilities of DataFromSky and how the advanced image data processing is contributing to optimize the urban mobility has been published on LinkedIn. Several use cases in which the data from the sky might be helpful are described by this article:
    – possibility of analyzing the traffic node in terms of traffic safety – based on the detection of risky situations, near accidents and collisions
    – analysis of interaction of vehicles, cyclists and pedestrians in public areas such as in surroundings of schools, city centers, bus and train stations etc.
    – studies of parking lots utilization, behavior of vehicles in a carpark
    – and many other applications which you can think about

    To summarize, the greatest benefits of traffic research from the aerial video using advanced software for image processing are:

    A) Accurate and detailed data about traffic from the bird’s eye perspective:

    – complete trajectory and moving patterns of each traffic participant
    – complex OD- matrix – vehicle counts, turning movements
    – speed and acceleration profile of each vehicle
    – vehicle classification into categories (car / heavy vehicle / bus, / motorcycle etc.)
    – measurement of travel time and stationary time (queuing time)
    – advanced heatmaps based on the velocity, acceleration, traffic flow
    – evaluation of traffic safety (detection of near accidents based on calculation of Time to Collision [TTC], detection of risky situations or inappropriate driving behavior, heavy breaking)

    B) Reliable, detailed research without influencing traffic behavior (inconspicuous solution).

    C) Ultimate traffic research, almost without a human intervention – based on the machine learning and DNN.

    D) Powerful tool which can improve traffic safety and urban planning of many Smart cities.

    DataFromSky measures speeding

    New video analysis comes from Czech Republic and measures the speeding!
    In this demonstration survey, we tracked 204 vehicles which traveled 114 kilometers in total, averaging 555 m per vehicle. The average speed was 34,5 kph.

    The video is displaying the sections with maximal speed allowed and highlights vehicles that have exceeded this speed. In the DataFromSky Viewer, you can create such a measured area simply using a polygon, where you can define the conditions under which the alert should appear (e.g. to which categories of vehicles does the rule apply, speed range etc.).

    Do you have a video you want to get analyzed? Send us an inquiry and we will create an advanced traffic study right away! Contact us directly at this link.

    Study of bicycle and pedestrian movement in Denmark

    John F. Kennedy’s Square in city of Aalborg in Denmark is with the railway station and bus terminal an important traffic hub that connects Aalborg to the surrounding towns and most of the bigger cities in country. With Aalborg Municipality’s desire and strategy to change the habits and move citizens from cars to bicycle and public transport, large space problems have arisen in connection with parking spaces for bicycles. The bike rails are crowded and illegally parked bikes fill up the street scene and create dangerous pedestrian situations.

    In order to find the optimal location of bicycle parking facilities, the movement patterns of each traffic participant, especially pedestrians and bicycles, were analyzed using DataFromSky advanced software – see the pictures attached below, representing the trajectories of bicycles (blue) and pedestrians (green). Based on these patterns, detailed data, statistics and trajectories information, COWI has performed a study examining where it will be possible to implement more parking places for bicycles in and around the square, resulting with a proposal for how the space can be furnished – offering more space for bicycle parking and rest areas for pedestrians.
    DataFromSky analysis has also resulted in illustrations of average speed of pedestrians in this square. The data were used to design areas where pedestrians typically stop and where there may be a need for seating (e.g. near the bus station), moreover, these information and data are extremely valuable for a safety study in a given zone, which can be adopted by the municipality to make some changes in order to increase the safety of pedestrians and bicycles in analyzed area.

    New possibility of recording aerial video: special traffic balloon!

    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.

    For more information about this new special traffic balloon, please contact us.

    Traffic monitoring in Denmark – the land of bikes

    Recently we got to analyzing a video of a roundabout in Roskilde, Denmark. And because Denmark is called: The land of bikes, we didn’t focus only on vehicles but also on bikes! And here is the result of our traffic monitoring:

    Length of analyzed video: 15:38.48
    Number of objects being tracked: 298 (vehicles and bicycles)
    Total distance traveled: 79 354.4 m
    Average speed: 34.0233 km per hour
    Average distance on roundabout: 59.7474 m

    And we would also like to thank Dansk Drone Kompagni for providing us the video.
