OpenDD – A Large-Scale Roundabout Drone Dataset

The dataset OpenDD aims at providing a relevant dataset to improve trajectory prediction algorithms, as well as to provide naturalistic data for the simulation of other traffic participants. The dataset is an extensive anonymized trajectory dataset, covering seven roundabouts in Wolfsburg and Ingolstadt, Germany.

OpenDD covers trajectories and high precision bounding boxes of over 80,000 different road users tracked with a unique object id in over 62h of data, as well as HD map information of the seven covered roundabouts.

Remark, as by September 2020: The trajectory database of rdb1 was malformed in v2, and the splits and drivable area images from v1 have been corrected. Please make sure that you have the data corresponding to version 3 when using the dataset. The version can be seen in the name of the trajectory database.

Dataset Description

A detailed description of the dataset can be found in the aforementioned publication. Here we will only briefly describe the data included in the dataset. The complete dataset can be downloaded below, split up over the different roundabouts, as well as one small example sub-dataset. For using the splits defined in the paper, the definitions of the splits reside in $ROOT/split_definition, as shown in the structure of the dataset above.


Trajectory Databases (.sqlite)

The actual dataset contains one .sqlite database for each of the 7 roundabouts included in the dataset. Each such database includes a table for each recording of the given roundabout.

An exemplary database, containing only one recording (thus only one table) for rdb1 can be found in the example_data download provided below.

Each table contains information about all objects present during the corresponding recording. A row in the table represents one instance of a given object at a given time instant.









Row Id.




Timestamp of the given object instance. Counted from the beginning of the given recording.




Id of the object this instance belongs to. Unique over the dataset.




X-Part of the UTM 32N coordinate of the center of the object instance.




Y-Part of the UTM 32N coordinate of the center of the object instance.




Bounding Box angle relative to UTM 32N x-axis.




Velocity of the object.




Acceleration of the object.




Tangential acceleration of the object.




Latitudinal acceleration of the object.



Pedestrian, Bicycle, Car, Van, Truck, Motorcycle, Trailer

Class the object belongs to.




Width of the object's bounding box.




Length of the object's bounding box.


String in form of [Int]


Array of trailers that belong to the object.

UTM32N Geo-Referenced Bird's Eye View Images (.png, .jpg and .tfw)

The actual dataset contains one .png image, one .jpg image and one .tfw World File (→ external link) for each of the 7 roundabouts covered by the dataset. The $ROOT.jpg contains the image of the roundabout, where private areas are anonymized by black polygons. The $ROOT_drivable_area.png contains a visualization of the drivable area of the $ROOT roundabout, which is directly derived from the areas defined in map_$ROOT_UTM32N.xml. The corresponding .tfw World File (→ external link) contains 6 lines, as follows:

0.02466059 # x-Component of the pixel width
-0.00230412 # y-Component of the pixel width
-0.00215162 # x-Component of the pixel height
-0.02544322 # y-Component of the pixel height
619245.36794307 # UTM x-Coordinate of the center of the upper-left pixel
5809189.40151734 # UTM y-Coordinate of the center of the upper-left pixel


Exemplary Data Visualisation

Visualisation of all trajectories in a given recording

Here all trajectories of the exemplary dataset on rdb1, provided below, can be seen. The trajectories are overlaid on the geo-referenced image using the UTM coordinates and the provided world file:



Visualisation of a given time instant in a recording

Visualisation of the a given time instant in a recording of rdb6 in the original video. Here, the high accuracy of the provided tracks can be seen.

The color of the OBJID visualizes the object's class.

  • Red - Car
  • Pink - Truck
  • Yellow - Trailer
  • Green - Pedestrian
  • Blue - Bicycle

For object 59 on top of the image it can be seen how trailers are detected and tracked separately, while the correspondence to the towing object is still provided.



The whole dataset is split up in 8 downloads, as listed below. The downloads contain exemplary data or the all data on one of the 7 roundabouts, and follow the file structure listed above in the description of the dataset contents. For using the splits defined in the paper, the definitions of the splits reside in $ROOT/split_definition.

We additionally provide a smaller download "exemplary_data" which includes the trajectories of one recording and the related images and map. This exemplary dataset should suffice to get a first impression of the data contained in OpenDD without the need for a larger download.
