Improved models for better decisions planning models, traffic operations models, and activity-based models.

Decisions about spending public funds for transportation improvements often are informed by estimates and forecasts developed through mathematical models. The more closely these models represent reality and include important influencing factors, the more confidence we can have in spending decisions. Models that can provide a better basis for predicting how highway improvements affect congestion, for example, or that reflect the differences in forecasting freight demand and passenger transportation will provide a more reliable picture of future needs. This project brief describes five projects from the SHRP 2 Capacity and Reliability focus areas that are working to improve existing planning models, operations models, and activity-based models.
