DataFromSky mistaken for aliens!

Unidentified object in the skies of Trento, Italy – Aliens? Most of the citizens and local journals could think that, read some of the local newspapers. Do not worry, there is no danger of alliens attack so far, DataFromSky has a simple and reasonable explanation!

Using a special balloon for traffic data collecting, new DataFromSky traffic analysis near the city of Trento in northern Italy was undertaken within last weeks. Specially designed ballon was used for a 3hour long study of traffic flow in the multilevel roundabout as shown in the attached image. This helium-filled balloon has many advantages for the persistent traffic monitoring, in comparison to commonly used drones and UAV, as the operating time of the balloon can reach up to 5 hours! To get more information about this solution and its specification, read this article or contact us directly on info@datafromsky.com.

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].

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.

    Camera on a balloon for studying traffic in the city of Alba

    Flow analysis, speed and critical points in the city of Alba
    “DataFromSky”, in other words, data that arrives from the sky through the shootings of a camera placed on a balloon. It was not so difficult to see one of these during these days in the industrial area located in Corso Asti, where the local study “TrafficLab” is going to analyze the traffic from the sky. “This is an analysis that we need for planning the new commerce building placed in this area” says the municipal officer. The results are still processing. Andrea Marella, engineer at TrafficLab, says: “We realized some aerial video at a height about 50/60 meters. The results are really interesting, because it is possible to see the traffic from a different perspective.” And explains: “This is a new methodology developed about three years ago that allows to analyze the vehicle movements from the sky. This service doesn’t interference with the sensitive data, and helps to get information automatically with our software. This can give us the number of the vehicles on the road, the traffic flow, the directions, the speeds and the conflict points.”

    Looking for solutions
    The camera is attached to a balloon inflated with helium. Marella adds: “We cannot use drones, because it is too difficult to have authorizations. We work in this way from a long time, with motorway companies, shopping centers and traffic local authorities and the results are very satisfactory. In this way we can have a wider vision that allows to report potentially critical situations and to find out how to solve them.”
