SOUTHWEST TRAFFIC ENGINEERING LLC

Southwest Traffic Engineering LLC specializes in transportation infrastructure planning and traffic systems engineering, delivering technical solutions that enhance mobility, safety, and operational efficiency for public roadways. Their core capabilities include traffic signal design, intersection optimization, signal timing analysis, traffic impact studies, and intelligent transportation system (ITS) integration. The firm applies industry-standard modeling tools and federal guidelines such as the MUTCD and ITE methodologies to develop data-driven traffic control strategies. Key differentiators include a focus on pedestrian and cyclist safety enhancements, adaptive signal control applications, and coordination with local transportation authorities to align engineering solutions with regional mobility goals. Their technical expertise spans signal phasing and timing, capacity analysis, traffic simulation software, and compliance with FHWA and state DOT standards. Award history does not provide sufficient detail to identify specific agencies or project types, so no definitive agency relationships can be confirmed. Similarly, without available contract data, no specific vertical specializations or recurring project scopes can be inferred. The company operates under NAICS 541330, which classifies it as an engineering services provider focused on traffic and transportation systems. In practice, this means delivering consulting engineering services that support the planning, design, and implementation of surface transportation infrastructure, particularly at the municipal and state level. The firm positions itself as a technical advisor in urban and suburban traffic management, with an emphasis on performance-based engineering outcomes. Southwest Traffic Engineering LLC is a Women-Owned Small Business and Woman-Owned Business certified under federal programs, reflecting its status as a small, owner-operated firm with government-recognized minority business credentials. Headquartered in Phoenix, Arizona, the company serves regional transportation agencies across the Southwest, leveraging local knowledge and state-specific regulatory familiarity to deliver context-sensitive engineering solutions.
