Autonomous Vehicles and Their Role in Construction

The construction industry is rapidly evolving, driven by advancements in technology and automation. One of the most transformative innovations is the use of autonomous vehicles (AVs) on construction sites. These self-operating machines are reshaping how projects are executed, enhancing efficiency, safety, and cost-effectiveness. Here’s an in-depth look at the role of autonomous vehicles in construction and their potential to revolutionize the industry.

What Are Autonomous Vehicles in Construction?

Autonomous vehicles in construction are machines equipped with sensors, cameras, GPS, and artificial intelligence (AI) systems that enable them to operate without direct human intervention. These vehicles include autonomous excavators, bulldozers, haul trucks, and drones, all designed to perform tasks with precision and minimal supervision.

Applications of Autonomous Vehicles in Construction
