MDOT discusses future drone applications for safety and efficiency enhancements

The Appropriations Subcommittee on Transportation convened on April 16, 2025, to discuss the Michigan Department of Transportation's (MDOT) Unmanned Aircraft Systems (UAS) program and its future applications. The meeting highlighted the program's evolution and its potential to enhance safety and efficiency in various transportation-related tasks.

The discussion began with an overview of the UAS program, which was initiated approximately six years ago. It was originally developed to assist in capturing aerial images for communication purposes. Since then, the program has expanded significantly, engaging with different MDOT regions to explore how drones can improve safety for personnel working on highways.

Key applications currently being explored include agricultural uses, particularly roadside pesticide application, and bridge inspections. The use of drones for bridge inspections was emphasized as a critical safety improvement, allowing inspections to be conducted without placing workers in potentially hazardous roadside conditions. This method is seen as a way to enhance safety while maintaining thorough inspection standards.

Additionally, the UAS program is being utilized for general surveying and data collection, which has proven to be a time-saving and cost-effective alternative to traditional methods. The department noted that employing drones for these tasks reduces the need for large teams of surveyors in the field.

A follow-up question addressed the financial efficiency of using drones compared to standard inspection methods. While specific financial data was not immediately available, it was noted that the cost of drones, typically ranging from $3,000 to $5,000, is significantly lower than the annual cost of employing a traditional inspector, which can exceed $150,000 when benefits are included.

In conclusion, the meeting underscored the MDOT's commitment to integrating drone technology into its operations, highlighting both current applications and future possibilities. The discussions pointed to a strategic shift towards utilizing innovative technology to enhance safety and efficiency in Michigan's transportation infrastructure. Further data on financial impacts and operational efficiencies is expected to be gathered for future discussions.
