Improving the traffic conditions in Brussel with DataFromSky

Our partner Roelofs has made an analysis with DataFromSky for a big junction in the city center of Brussel, Belgium. The analysis covers the junction between the Leopold II Lane and Sainctelette – one of the biggest and most complex junctions in Brussel. In this case, the video is made by a tethered drone to get a longer survey. Thanks to DataFromSky, it is possible to create a detailed traffic study which was handled to the government of Brussel and its Mobility department, providing the correct data for creating solutions that can improve the traffic flow and safety of this junction.

DataFromSky Aerial analysis is providing complete and detailed telemetry data about each traffic participant:

  • complete object trajectories (time, position, speed, acceleration in coordinate system UTM or WGS84) – visualization in program or various exports
  • classification of all objects into 7 main categories (including bicycles and pedestrians)
  • vehicle counts via configurable counting gates
  • detailed OD matrix and turning movements count in defined directions
  • speed and acceleration anywhere in the scene, heatmaps
  • lane assignment
  • measurement of critical headway (gap) and follow-up headway
  • safety analysis (Time to collision measurement, PET, Heavy breaking etc.)
  • and much more!

    Traffic Behavior and Safety study in Denmark

    In many cities, there are places where many road users pass or stay in a complicated network of routes and get into a risky interaction. It can be difficult to get an overview of the whole situation and define the “hot spots” where the traffic behavior is simply non-standard. Our tool Data From Sky is in most cases be able to uncover, sort and analyze all movements of vehicles, cyclists and pedestrians in a larger area and evaluate critical parts of a road network, that might be risky for any traffic participant. This kind of overview and analysis can give traffic and urban planners a very good starting point for designing any adjustments.

    The figure below shows an area in the city of Aarhus in Denmark and displays the flow of cyclists (pink trajectories) and pedestrians (green trajectories) in the 2-hour period. The main goal of the analysis is to provide the Aarhus Municipality with an overview of cyclists and pedestrian movement in the analyzed area and identify some patterns in their traffic behavior.

    After having formed a detailed overview of all the different flows and routes, author of this study (Birger Villadsen, Traffic Specialist at COWI) has focused on those areas, where cyclists’ and pedestrians’ behavior gets into a collision. The detailed DataFromSky Analysis helped to analyze the problematic spots and draw up proposals for changes, that can help to simplify the traffic flow. Aarhus Municipality will evaluate the list of proposals and test them on the site by making temporary changes and observing whether they have the intended effect before the changes are implemented permanently.

    Safety analysis using data from 8 drones at once!

    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.

    Analyzed area

    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?

    1. top-down view position (bird’s eye perspective)
    2. space overlap – at least 10 % of overlap in the analyzed area from each side
    3. 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:

    DataFromSky & COWI on Vejforum Event in Denmark

    In upcoming days, you have a chance to see DataFromSky solution and its practical use cases and demonstration on an event related to the Road & Transportation. Visit the stand of COWI, our partner for Nordic countries, on Vejforum 2017 event, an exciting conference with the theme “Roads, people and technology”, held between 6. and 7. December 2017 in Hotel Nyborg Strand, Denmark. For more information, visit the event’s website

    DataFromSky – the world’s most advanced traffic analysis
    It will also be demonstrated how advanced technologies such as computer vision, neural networking and deep learning can be used and implemented in the world’s most advanced software for comprehensive traffic analyzes and also how to utilize this solution to detect the occupancy of a parking lot in real time using an ordinary IP cameras and the AI behind.

    One of the topics presented on this event will be the “Accident Portal” – new web-based analysis tool developed by COWI that gives the Danish municipalities completely new opportunities for quickly, efficiently and through a user-friendly interface to work with traffic accidents data. The team of DataFromSky is currently working on a project evaluating the safety of a traffic node to know the potentionally risky situation and detect near accidents and accidents. This feature could be possibly utilized in the Accident Portal mentioned above.

    Road safety in EU

    A month ago, EU Observer, an “independent online newspaper which values free thinking and plain speech“, published an article with a provocative title “Why is road safety not higher on EU agenda?“.

    Chart of fatalities on EU roads
    Fatality rate development in the EU

    Disregarding the somewhat sensationalistic title, the article draws attention to an important fact: While the union pledged in 2011 to halve traffic-related deaths by 2020, the reduction is not exactly going on any more. In the press releases “Road Safety: new statistics call for fresh efforts to save lives on EU roads” and “2015 road safety statistics: What is behind the figures?” the European Commission noted that its road are the safest in the world, but there has been no progress on this front since 2014 – two years in a row. The European Transport Safety Council seconded this with a press release of their own, “Urgent action needed on road safety as new figures show increase in deaths”.

    Details of road fatalities by country - chart
    Fatalities per million inhabitants by country

    Diving into the wealth of charts accompanying the Commission’s press release, it is clear that the EU is divided between west and east in this regard, too. Should the eastern part somehow catch up, the targets would look far more reachable. Yet more alarming part of the statistics is that the vulnerable road users – pedestrians and bicyclists – saw hardly as much of improvement as vehicle occupants. Worth mentioning is that the statistics related to injuries have started being reported in a common format, which will enable better tracking of these injuries.

    The various sources mention several ways forward, including passing new legislative – increasing protection of vulnerable road users and revisiting the 2008/96/EC directive on infrastructure. The ETSC specifically calls out delays to a number of such changes as critical. Apart from these, cooperative ITS is mentioned, and Violeta Bulc, EU Commissioner for Transport, adds promotion of self-driving vehicles.

    At DataFromSky, we take safety seriously, especially that of vulnerable road users. We are steadily working towards making our services and products better to help understand road users’ interactions – not just for vehicular traffic, but others too. We too hope that technology can contribute to these efforts. We do not mean better cars, however. Better understanding of what happens on the road, using methods exploiting IT and otherwise austere with physical resources: that is what we hope for – and what we bet on, too.

    ISO 39001 Road Safety seminar mentions DataFromSky

    At the end of July, our Italian partner, Andrea Marella of Traficlab.eu, led an online seminar about road safety titled “Road traffic safety (RTS) management system standard“. DataFromSky was mentioned as one of the best ways to gather information about driver behaviour and safety.

    During 2012 the International Organization for Standardization published a new standard called: ISO 39001:2012 – Road traffic safety (RTS) management systems – Requirements with guidance for use. The ISO provides a tool to help organizations to reduce and ultimately to eliminate the incidence and risk of death and serious injury related to road traffic crashes.

    The webinar in question offered the following information and training:

    • Road safety concepts
    • Road risk factors
    • ISO 39001:2012 standard requirements
    • Road traffic safety (RTS) in the management systems
    • Guidelines for auditing a RTS management system

    DataFromSky was mentioned as a great source of data, and we must agree. The conflict heatmaps from simulation on next slide are exactly what we can deliver! Furthermore, we can do this from real data.

    Stay tuned for more news about road safety…
