Call Description

Unmanned Aerial Systems (UAS) have started to revolutionize the field of traffic data collection, unleashing opportunities to advance the theory and practice in collecting, understanding, and modeling traffic based on large video streams. With the overwhelming amount of data being gathered by such systems, new opportunities for a detailed analysis of vehicle movements, atypical traffic patterns and multimodal interactions in urban environments are unleashed.


We are happy to announce the UAS4T Competition, which will be held at the 23rd IEEE International Conference on Intelligent Transportation Systems. This year’s competition is organized by the IEEE ITSS Technical Activities Sub-Committee “Transportation 5.0”.


The scope of the competition is to evaluate the accuracy of statistical or CI methods in transportation-related detection problems with specific reference in queue formation in urban arterials. The focus will be on obtaining results as close as possible to the real data. Solutions that will advance the current understanding in advanced computing, data preprocessing and traffic dynamics will be also favored. The competition is open to Teams (single participant or group of participants) that are willing to present their work at the IEEE ITSC 2020.


The competition will run in two stages: in the first stage (pre-selection), the problem will be made available via email to the registered teams and submissions will be ranked according to estimation accuracy. The top 3 submissions will proceed to the next stage, which will take place on September 23, 2021 during the IEEE ITSC 2020, where the selected teams will briefly present their work (15 minutes for each presentation). The Organizing Committee will select the winner based on four criteria: i. Accuracy (50%), ii. Degree on novelty (25%) and iii. Quality of the code (10%), and iv. Quality of the presentation (15%). The first prize is €2000. The winner will be announced during the IEEE ITSC 2020.

Problem Description

The data that will be used for the competition will be shared with all the registered teams on August 1st. A similar dataset can already be found online on (pNEUMA sample dataset). The UAS4T Competition data will include trajectories that were monitored by one (1) single drone covering a wide area over the central district of Athens, Greece. Both major and minor roads, bus stops and signalized intersections are included in the study area. The dataset includes trajectories from cars, taxis, powered two-wheelers, buses, medium and heavy vehicles. Participants are asked to develop a scheme to estimate the maximum length of the queues per lane that are formed for different approaches of an intersection and roads (to be specified) during the monitoring duration. Thus, for every specified area, the teams will have to report: i. Maximum length of queue, ii. Lane the maximum length occurred, iii. Coordinates of the start and end of the maximum queue, iv. Timestamp of the maximum queue occurrence, and v. whether, when and where a spillback is formed (when applicable).
