Real-Time Traffic System Cuts Intersection Deaths and Congestion Costs

National Laboratory of the Rockies' open-source traffic toolkit targets 25% of US traffic fatalities and $300B in annual crash costs

The National Laboratory of the Rockies developed IPC-Fusion, an open-source traffic management toolkit available for licensing. This system integrates real-time data from cameras, lidar, radar, and connected vehicles to optimize signal timing at intersections. Current US traffic crashes cause at least 40,000 fatalities and $300 billion in economic losses yearly, with intersections accounting for 25% of fatalities and 50% of injuries annually. Federal Highway Administration data shows signal optimization can reduce traffic delays by 15-40% and fuel consumption by up to 10% in specific scenarios.

IPC-Fusion enables adaptive traffic control at intersections, directly addressing the highest risk zones. The technology targets reductions in intersection-related crashes and congestion costs, with the National Laboratory in discussions with a major traffic solutions provider for broader adoption. This represents a shift toward data-driven, real-time responses to traffic hazards.

For mobility and security, IPC-Fusion could lower the economic burden of crashes while reducing collision risks at critical intersections. By targeting the 25% of fatalities that occur at intersections, it addresses a high-impact area where congestion costs and safety risks converge. However, implementation parameters vary by geography, and Federal Highway Administration figures apply only to specific signal optimization contexts. The next step depends on the lab’s partnership with the traffic provider to scale this technology beyond pilot sites.
