National Technical University of Athens PTW research using DataFromSky

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.

Motorcycle traffic monitoring and interaction research

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 [1][2].

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.
