Mike On Traffic mentions DataFromSky

Mike On Traffic is a blog about “the Less Boring Side of Traffic Engineering“. DataFromSky was recently mentioned in a post called Counting Cars from the Sky: The Future of Traffic Monitoring.

Drone traffic monitoring demonstration in Netherlands

At the beginning of July, sUAS news reported about drone traffic monitoring demonstration in Netherlands.

front page of magazine

Traffic technology International, an international web-and-print magazine, published in their June/July 2015 issue an article about UAV-based road traffic monitoring based on the Netherlands event under the title Farewell to fixed cameras?.

While the one-off demonstration showcased real-time monitoring, not analysis, it is an application of UAVs in traffic nevertheless. The article title is especially poignant for us, since drones can replace fixed cameras for both monitoring and analysis.

Meanwhile, another monitoring application is on the horizon: “The Jakarta City police to use drones to monitor traffic”. Doubtless, many more are to come…

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…

Videos from Bayonne, France

Working together with UAV640, we took a look at a roundabout in the center of Bayonne and ran our analytic tools on it.

As you can see, DataFromSky can use higher resolution just fine…

Venice – Final analysis

You probably remember the recording in Venice: Blimp recording in Venice, Recording in Venice in detail. We have obtained permission to share some of the results, so we can show you what can DataFromSky do for you, too!

Speed profile

The speed profiles for both areas were extracted.

At a glance, one can see what speeds belong to which path through the crossroads. It is also plainly visible which trajectories belong to slow and which to speedy drivers. In this case, the total area captured and analyzed is too small to show bigger changes in speeds, though.

Speed profile, Portegrandi T-intersection

Area coverage

Density of trajectories corresponds to area usage. One can thus estimate how much of the road’s width is actually used by passing vehicles, and where the wear of roadway is most intensive.

Conflict areas

DataFromSky can detect situations where vehicles become too close, or have to slow down to let each other pass. This is a visualization of these events’ spatial distribution. You can easily see that there is a single point for the T-intersection and estimate from the pattern at roundabout that its southern leg is far less used.

Deflection and radius analysis

Deflection angle and radius analysis, Caposile roundabout

Deflection angle denotes the part of road which requires circular movement. Radius describes the size of that circle. Both can relate either to the shape of road, or actual trajectory used by vehicles.

DataFromSky provides real vehicle trajectories, so actual deflection angles and radii can be measured. These depend on the combination of entry and exit points, so it’s natural to split the trajectories into groups. Again, with DataFromSky you are not left wishing for features.

Road design validation

Road design validation, Portegrandi T-intersection

Last but not least, the trajectory data from DataFromSky is exactly what you need to validate design of the road. Whatever the design process, verifications, and modelling tell you before, here you get real data about the situation.

Pictures used in this post are only illustrative and do not match the text perfectly. All trajectories are visualized, instead of particular groups.
