Considering that roads have a direct and significant impact on people's lives, maintenance and management of roads need to be done exhaustively from time to time. However, a lack of financial resources makes many local governments unable to conduct sufficient inspections on time. Some municipalities automate road damage detection by using high-performance sensors. Nevertheless, the high cost of these sensors makes it infeasible to use them at the country level owing to the vast area of roads to be inspected

Therefore, there arises a need for a system that makes it easy to assess the road conditions and identify the damage to the road surface at a low cost. Recognizing this need, the first Road Damage Detection Challenge was organized as an IEEE Big Data Cup in 2018 to evaluate the contemporary methods working towards the same goal.

Another challenge (Global Road Damage Detection Challenge, GRDDC’2020) was organized in 2020 to address the requirements of multiple countries. GRDDC utilized data from India, Japan, and Czech Republic. More details may be accessed at (

This year, another challenge is here with new opportunities. In previous challenges, the participants were restricted to using only the challenge dataset to train the models. This year, this constraint has been eliminated by allowing participants to develop/propose their datasets. The central theme of the challenge this year is "Crowdsensing," – which refers to the crowdsourcing of sensor data collected as per the choice of contributors.

Anyone having the dataset may register as a data contributor, data recommender, or information provider by participating in the first two phases of the challenge. After a suitability analysis, the selected datasets will be added officially to the CRDDC'2022 dataset and made available to the participants for phase 3.

Successful implementation of this challenge would open new possibilities where just the smartphones and drive cameras would be enough for road inspections, not for a single country but all countries worldwide.

The Task

The challenge will be organized in four phases with different tasks for the participants. The details are as follows.

Phase 1: Data Solicitation: The participants need to submit a report of their proposed road damage dataset (cracks, potholes, or any other damage categories) by providing the details through the corresponding forms. Following categories of participants are considered:

  1. Data Contributors (Data owners who wish to contribute their data to CRDDC)
  2. Information Providers (Data owners who wish to participate by providing only the information related to their dataset, keeping the data private)
  3. Data Recommenders (Researchers/Academicians/Freelancers.... who wants to recommend the inclusion of others' datasets to CRDDC)
Please refer to Submission section to access the forms.

Phase 2: Data Shortlisting: Based on the reports submitted in phase 1, the shortlisted teams need to submit a link to their proposed dataset. After verification, the winners (data contributors) of phase 1 will be announced.

The solicited datasets will be added to the Challenge datasets for the next phase of the challenge.

Phase 3: Main Task: Use any combination of the CRDDC data and train road damage detection and classification models considering Objective 1, Objective 2 or both:

  • Objective 1: Maximize accuracy (F1-Score) for individual countries (India, Japan, US, Norway)
  • Objective 2: Maximize accuracy (F1-Score) for multiple countries (India, Japan, Czech, US, Norway, China).

The participants may propose models targetting one or multiple countries, concerning Objective 1 and 2. For instance - Model A for Country 1, Model B for Country 2, Model C for Countries 3 & 4, or a single model for all countries may be proposed. Average of score for all the leaderboards will be used to determine the winners.
Further, the challenge imposes no restrictions on the type of submission and welcome all the novel algorithms, techniques that are currently under review, and methods that have already been published. A summary of the models proposed by the participants of previous Big Data Cup (GRDDC'2020) may be accessed at (

Phase 4: Report and Source Code: In phase 4, the participants need to submit a report of their proposed solution along with the source code. The submission will be used to finalize the winners

Note: After the competition phase is completed, a link for submitting the accompanying academic paper will be provided to the top 10 participants (may be increased based on the quality of submissions) as ranked by the public/private leaderboard weighting. For more details, please refer to the Submissions section.

Phase 4 Report Submission September 21, 2022 - September 30, 2022

**** It may be noted that the participants who do not have any data to contribute may choose to participate directly in Phase 3 or may suggest the inclusion of data available from others to participate in Phase I (as Data Recommenders). For those already having their data (private or public), it would be an added benefit to release the data through the CRDDC since the data would reach a global audience through a well-established platform. ****
