Traffic Engineering Expertise

Our data-driven traffic engineering solutions improve safety, mobility and reliability across all modes of travel. Our team of traffic engineers, planners, engineers and data technicians pair technical insight with practical design experience to create systems that move people and goods efficiently and support long-term community growth. From corridor studies and intersection upgrades to regional traffic management and signal coordination, we help agencies make informed decisions that create more connected communities.

Addressing Modern Transportation Challenges

Population growth, aging infrastructure and increasing multimodal demands are straining transportation networks across the country. Transportation agencies are challenged with maintaining safety and efficiency while adapting to new travel patterns, technologies and funding priorities. We help these agencies identify where and why traffic issues occur using data collection, modeling and analysis to reveal patterns that drive congestion, crash risk and operational inefficiency. These insights translate into actionable design and management strategies that address near-term operations while preparing communities for long-term resiliency.

Traffic Engineering Solutions

Stanley Consultants provides end-to-end traffic engineering services that move projects efficiently from concept through implementation.

Traffic Data Collection and Analysis: Accurate, defensible data guides every project decision. Our team collects and interprets traffic counts, probe data and travel-time information to evaluate system performance, identify bottlenecks and guide investment priorities.
Traffic Modeling and Simulation: Calibrated microsimulation and network models replicate existing and future conditions, providing insight into congestion, safety and operational performance. These models help agencies make data-driven design and policy decisions with confidence.
Transportation Planning and Corridor Studies: Planning efforts link system performance to funding and design. We prepare corridor and area-wide studies that balance multimodal needs, land use and community goals, delivering clear recommendations that advance projects through completion.
Traffic Safety Planning and Design: Creating safer transportation systems starts with understanding crash trends, roadway conditions and human behavior. Using traffic data and crash analysis, we identify high-risk locations and apply Safe System principles to design targeted improvements that build safer, more connected communities. Through Safe Streets and Roads for All (SS4A) initiatives, we partner with communities to turn data-driven plans into built projects that reduce accidents and deliver lasting safety improvements.
Intelligent Transportation Systems (ITS): We design and implement ITS that integrate real-time monitoring, adaptive signal control, connected vehicle technology and pedestrian safety enhancements to improve efficiency, reduce congestion and increase safety across transportation networks.
