Uncertainty is inherent to forecasting—from the underlying data used for estimation and calibration to the estimated variables within the models to the input assumptions about future conditions.
We have been developing travel demand forecasting models for over 40 years, including some of the most challenging and visible modeling projects in the nation. We pioneered many of the travel demand forecasting practices in use today.
As the largest and most experienced group of transportation modelers in the industry, we have been developing travel demand forecasting models for over 40 years. We are experts in both activity-based modeling and more traditional trip based modeling for both passenger and freight applications.
Many areas of the country are struggling to attain national ambient air quality standards, develop greenhouse gas (GHG) mitigation plans, and address mobile source air toxics (MSAT) that may affect public health. CS brings broad expertise to these issues, partnering with agencies to model emissions and assess strategies for reducing emissions from transportation sources.
