Introduction
The Department of Transportation (DOT) is harnessing the power of AI to enhance safety, efficiency, and accuracy across its various operations. From improving weather forecasting for aviation and maritime activities to automating intelligent traffic systems in rail and road transportation, AI is playing a pivotal role in advancing the department’s mission. These AI-driven initiatives are not only improving real-time decision-making but also optimizing long-term maintenance and operational strategies. According to Markets and Markets, “The artificial intelligence in transportation market was valued at USD 1.00 Billion in 2016 and is projected to grow at a CAGR of 17.87% during the forecast period. The base year considered for the study is 2016 and the forecast period is from 2017 to 2030.” The following use cases demonstrate how the DOT is integrating AI to tackle complex challenges, ultimately leading to safer and more efficient transportation systems.
Use Cases
-
1. Remote Oceanic Meteorological Information Operations (ROMIO)
This project, ROMIO, evaluates the feasibility of providing convective weather information to aircraft over oceans and remote areas. It converts satellite, lightning, and weather model data into thunderstorm activity and cloud top height information, using AI to enhance accuracy based on historical data.
-
2. Determining Surface Winds with Machine Learning Software
This project uses AI to analyze camera images of wind socks, providing accurate surface wind speed and direction information in remote areas without weather sensors. This technology improves weather monitoring and safety in areas lacking traditional observation equipment.
-
3. Automated Delay Detection Using Voice Processing
This project focuses on automating the detection of delays in air traffic control (ATC) and aircraft interactions through voice processing. By capturing and analyzing voice communications, the system aims to identify delay events that are often unreported, such as vectoring, thereby improving the accuracy of delay accounting in aviation operations.
-
4. Course Deviation Identification for Multiple Airport Route Separation (MARS)
The MARS program is focused on creating a safety case to support reduced separation standards between Performance Based Navigation (PBN) routes in busy terminal airspace. This initiative aims to improve operational efficiency and safety by allowing for better management of air traffic in high-demand metropolitan areas, potentially reducing delays and enhancing airport capacity.

5. Machine Learning for Occupant Safety Research
Implement deep learning to predict crucial crash parameters, Delta-V (change in velocity) and PDOF (principal direction of force), directly from real-world crash images. Delta-V and PDOF are vital for assessing injury outcomes. By leveraging deep learning models, we can bypass the need for WinSmash software and manual estimations by crash examiners. This approach allows us to obtain Delta-V and PDOF within milliseconds, significantly improving the speed and efficiency of crash analysis, which is critical for timely decision-making and response as well as providing crucial data for assessing the severity and impact of the crash.

6. Offshore Precipitation Capability (OPC)
The Offshore Precipitation Capability (OPC) project integrates data from various sources, including weather radar and satellite imagery, to create accurate precipitation forecasts. By applying machine learning techniques, the project enhances the precision of these forecasts, providing critical information for maritime operations and safety.
-
7. Development of Predictive Analytics Using Autonomous Track Geometry Measurement System (ATGMS) Data
This project focuses on using data from the Autonomous Track Geometry Measurement System (ATGMS) to develop predictive analytics for railway track maintenance. By applying machine learning to analyze track geometry measurements, the project aims to identify locations that require attention, improving safety and maintenance efficiency in rail operations.
-
8. Crushed Aggregate Gradation Evaluation System
This project utilizes deep learning and computer vision techniques to analyze the grading of crushed aggregate particles. By automating the evaluation process, the system enhances the accuracy and efficiency of aggregate quality assessments, which are crucial for construction and infrastructure projects.
-
9. Automatic Track Change Detection Demonstration and Analysis
This project utilizes a DeepCNet-based neural network designed to identify and classify various track-related features, such as fasteners and ties, specifically for applications focused on change detection. By analyzing line-scan images obtained from rail-bound inspection systems, the system can effectively notify stakeholders of any changes from the established status quo or between different inspections, enhancing the safety and reliability of rail operations.
