As pioneers of modeling and simulation practices in use today, CS pairs national best practices, real-world approaches and local perspectives to assist agencies in modeling multimodal transportation systems analysis; integrating macroscopic, mesoscopic, and microscopic models; and developing new techniques and guidance for simulation.

Here’s how we can support your agency:

Simulation Support

CS advises local, regional, state and Federal authorities on the implementation of simulation. We assist the agencies and model practitioners in the application of analysis tools, providing guidelines and training on best practices for selection, development, calibration and application.

The Federal Highway Administration called upon our experts to develop several volumes of the Traffic Analysis Toolbox series of guidance and best practices. Using our extensive knowledge of these works, we train agency staff in development, application, postprocessing and documentation of simulation models.


We generate tailored mesoscopic or microscopic simulation models. Our simulation project development experience includes express toll lanes, border crossings, automatic traffic management systems, bottleneck removal and transit models.


Integrated Corridor Management and Active Transportation and Demand Management

Applying Integrated Corridor Management (ICM) and Active Transportation and Demand Management (ATDM) strategies can dynamically help reduce congestion “hot spots” and improve the overall productivity of transportation systems, especially under unexpected or atypical conditions. We partner with you to implement ICM and ATDM technologies that efficiently and proactively manage the movement of people and goods in transportation corridors and networks.

Managed Lanes, Toll Roads and Express Lane Modeling

We develop simulation models to assess managed lanes, toll roads and express lanes. Our sophisticated tools and approaches analyze the speed effects of bottlenecks, system designs, a driver’s willingness to pay tolls and pricing strategies. These models predict congestion under different pricing conditions and help roadway designers develop the most efficient ingress and egress points to help the agency make sound transportation investments while also generating revenue.
