AtkinsRéalis Expands SIMULATOR Digital Suite to Strengthen Infrastructure Resilience

Atlanta, GA – AtkinsRéalis, a world-class engineering services and nuclear company with offices around the world, today announced the launch of SIMULATOR at the 2025 ITS World Congress, a comprehensive suite of digital resilience planning solutions designed to help clients predict, prepare for, respond to and recover from future disasters.

Building on the success of the award-winning City Simulator platform, the enhanced SIMULATOR suite features market-specific modules for cities, transportation, seaports, airports and installations. These tools enable asset owners to assess unique vulnerabilities, model risks and develop data-driven strategies to secure funding and enhance system resilience.

“As infrastructure systems become more complex and face increasing disruption risks, traditional planning methods are no longer enough,” said Donna Huey, Senior Vice President and Chief Digital Officer, AtkinsRéalis. “SIMULATOR empowers our clients with advanced modeling and simulation tools to turn uncertainty into strategy—delivering actionable insights that protect communities, strengthen critical systems and guide smarter investment decisions for a more resilient future.”

Each SIMULATOR deployment begins with the creation of a digital twin, a dynamic, data-driven model that replicates real-world infrastructure systems. It then incorporates forecasted growth trends including urbanization, population shifts and infrastructure development and evaluates infrastructure system performance under threats such as extreme weather, epidemics, and cyberattacks. By integrating diverse data sources such as stormwater infrastructure, power grids and zoning regulations, SIMULATOR insights allow clients to develop responsive resilience strategies that ensure long-term operational continuity while balancing economic, social and environmental priorities.

Communities are already leveraging SIMULATOR to identify, plan for and implement proactive resilience solutions:

• Atlanta, GA: Planning revealed that expanding tree cover and installing air-conditioned bus shelters could significantly reduce single-occupancy vehicle use, helping shape regional transportation plans.

• North Carolina Department of Transportation: Modeling along the US-74 corridor found that a 20% increase in annual infrastructure investment can prevent up to 80% of future traffic disruptions.

• Boulder County, CO: SIMULATOR showed that elevating and hardening three key bridges can reduce disruptions more effectively than 25 other strategies, insights that directly supported FEMA reconstruction funding.

“SIMULATOR is more than a digital tool, it’s a strategic partner in resilience planning,” said Stephen Bourne, SIMULATOR Project Director. “Our team works with clients to propose solutions that align with stakeholder priorities and funding frameworks, ensuring every plan is technically sound and financially viable.”
