SLH: Causal Inference – Difference in Differences Regression and Its Application in Transportation Research

In this course, we will discuss the Difference-in-Differences (DiD) method, a causal inference tool widely used across various research fields to estimate the impact of policy changes or other interventions while controlling for confounding factors. You will learn about its application in transportation research, with a recent study evaluating the effectiveness of congestion policies as an example.
