DataFromSky will participate in the International Congress on Transport infrastructure and systems (TIS) held in Rome in April 10.to 12.! You have a great chance to see DataFromSky in action and assess its capabilities. Don’t hesitate and visit the TIS conference in Rome to find out more!
One of the main topic discussed on the conference will be the emissions caused by traffic and their impact on human health. The EU Commission is preparing a strategy for clean transport, which should become effective after 2020 and it is in compliance with the strategy proposal for low-emission transport. One of the significant impulses is the increasing air pollution in cities and a high share (up to one third) of road transport in the creation of greenhouse gases. Nowadays, the total share of transport in the creation of greenhouse gases is around 23% (according to data collected by EUROSTAT).
What we are going to present on the Congress, is the possible approaches to solve this topical issue by using data obtained from the DataFromSky software for modelling of intensities and emission from traffic. This tool uses real traffic information about the monitored traffic area, such as the type of the passing vehicles, speed, acceleration profile or traffic density. Using these mentioned data, application of the DataFromSky software to measure the emission load in cities is currently being dealt with. The aim is to create a supporting tool for traffic control, which is in accordance with the Smart Cities concept and leads to reducing the emission load from traffic. We actively collaborate on this project with top researchers from Institute of Forensic Engineering of Brno University of Technology (doc. Ing. Vladimir Adamec, Csc. & Ing. Barbora Schullerova, Ph.D.) . This issue opens the door for further research and implementation in traffic research.
Other participant of the conference will be Andrea Marella, engineer at TrafficLab, our service partner from Italy. His paper “Implementing traffic simulation models with aerial traffic survey” descibes the method how to obtain both a complex set of data of OD matrix and detailed human driver behaviours data in order to set a specific scenario simulation. DataFromSky tool was involved and used in this research as well.

The PhD candidate Emmanouil Barmpounakis and his supervisors Dr. John Golias and Dr. Eleni Vlahogianni from The Department of Transportation Planning and Engineering at the National Technical University of Athens are using DataFromSky to study Powered Two Wheelers’ (PTW) overtaking phenomena using the principles of Game Theory:
Both the PTW driver and the driver of the vehicle being overtaken are assumed to be rational decision-makers that develop strategies, while commuting in urban environment, trying to get the best outcome for their decisions. These strategies may be cooperative or not based on both drivers’ choices with respect to the distances and safety gaps they leave from the lead vehicle. Since PTW follow unorthodox trajectories, especially in an urban arterial, having detailed naturalistic data is essential, and this is how DFS comes in handy!
We are always looking for partners from academic sphere. Are you a researcher in traffic or civil engineering? Don’t hesitate to contact us!
This video is an excerpt with no motorcycles present. You can see some new features of the Viewer: a lateral acceleration heatmap, distance measurement, and a testing bounding box makes a guest appearance too. Heatmap overlay is a completely new feature: When activated, you can configure it to display a scalar value. You can currently select from various speed, count and acceleration types of quantity. The color map and its value range are configurable as well.

Researchers from Technical University of Brno recently had an interesting idea: Use a number of students to simulate a convoy with human drivers and measure the dynamics of that situation. To do so, they turned to DataFromSky, their trusted research partner.
It is no coincidence that DFS turned out to be a great tool for such situation – our long-term vision is to be the tool for spatial movement analysis. The students’ positions were marked manually; the rest of needed processing was already part of our software.
Enough rambling, take a look!
Sam Ziusudras, from Curtin University’s Civil Engineering department is evaluating the reliability of the traffic data obtained from small Unmanned Airborne Vehicles in generating Origin-Destination matrices for intersections. As a part of this study, Sam and the research team will be flying a drone to capture video from the flow of the traffic through an intersection in Western Australia. The trajectories would then be extracted using DataFromSky Services, and finally compared to the ‘manual count’ of volume studies for any discrepancies.
Here’s a video from their first test:
Every now and then, an unique and interesting use case for DataFromSky comes up. The Department of Transportation Planning and Engineering at National Technical University of Athens is planning to use DataFromSky for traffic monitoring – to study interactions between powered two-wheelers (PTW) and other vehicles. They have already published a number of papers, dealing with powered two-wheelers’ overtaking in context of game theory or modelling based on multivariate statistics .
The smaller size of PTWs makes it possible to keep moving and overtaking even in conditions where cars are immobilized. In some countries, PTWs are either a dominant form of traffic, or take up a large share. Given these facts, there is a lot of opportunities to build a better understanding of their interactions – and hopefully also safety in these situations.
Below is a short video which we analyzed as a demonstration for the Greek scientists.
