Dynamic Traffic Assignment (DTA) is a cutting-edge traffic modeling approach that plays a crucial role in modern traffic management and transportation planning. Unlike traditional static models, DTA simulates traffic movements on a detailed representation of the road network and traffic management system to provide a more accurate and responsive analysis of traffic flow. This advanced model can support various applications, from regional-level evaluations of travel behavior to corridor-level traffic management, including bus rapid transit (BRT) operations and signal optimization. Recently, ITE Canada recognized the Regional Municipality of York and their project “York Region DTA Model – A Next-Generation Transport Planning and Operations Tool,” as one of five projects nominated for the 2025 ITE Transportation Achievement Award. This prestigious award highlights projects with significant contributions to the field of transportation engineering and their impact on improving traffic management and mobility. Key Findings The York Region Dynamic Traffic Assignment (DTA) Model improved traffic flow using Bentley’s OpenPaths traffic simulation software. The DTA Model reduced analysis time by 60% compared to traditional models. The model helped avoid unnecessary road widenings, saving millions in infrastructure costs. Future integration with the region’s Activity-Based Model (ABM) will enhance multimodal traffic modeling. Unveiling the York Region DTA
