Why AI-Powered Roadway Inventories Are the Future of Urban Planning

Discover how AI and geospatial data are supplementing manual road surveys. Urban SDK enables faster, accurate roadway inventories for smart city planning.

Urban SDK is leading the next evolution of roadway inventory through artificial intelligence and geospatial data. Traditionally, transportation departments relied on field crews equipped with measuring wheels, clipboards, and vehicles to gather data on lane widths, signs, and pavement markings. While this method offered accuracy, it was slow, costly, and often left cities with outdated datasets. Today, AI-powered roadway inventories are revolutionizing this approach by using computer vision and machine learning on satellite, aerial, or street-level imagery to automatically identify road features at scale.

With Urban SDK's Roadway Characteristics dataset, users can leverage AI and satellite imagery to efficiently survey roads, curbs, signals, signage, and more—reducing years of manual work to hours. The fusion of AI with geospatial intelligence (GeoAI) enables municipalities to capture and update road networks consistently, regardless of their complexity. In a California pilot, for example, AI systems mapped thousands of miles of sidewalk 45 times faster than traditional methods, demonstrating transformative time savings.

Traditional vs. AI-Powered Approaches

Manual GIS Surveying

Transportation agencies have long gathered roadway data through manual surveying. Crews walk or drive roadways, using measuring tools and notebooks to log data.

Although reliable, this method covers limited ground each year and often results in outdated information.

Mobile Mapping Systems

Some cities have adopted lidar-equipped or camera-mounted vehicles that scan roads while driving.

This enhances data capture but still requires considerable manual processing, such as reviewing video footage to identify features.

AI-Powered Automation

Urban SDK and similar platforms revolutionize this process. By processing aerial or satellite imagery through AI models, these tools automatically extract attributes like lane widths, surface types, pavement conditions, and signage.

The result is a scalable, repeatable, and current dataset that updates with new imagery.

Benefits of AI-Powered Roadway Inventories
