This research assesses how U.S. transit agencies have taken advantage of congestion pricing projects and answers two questions: (1) what role has transit played in U.S. congestion pricing projects and (2) how have transit agencies responded to congestion pricing projects through service planning, operating practices, capital investment and institutional arrangements. First, a macro-level assessment is conducted of twenty-two congestion pricing projects. Second, a microlevel analysis comparing two congestion pricing projects in Northern Virginia is made.
