Activities of joint subcommittees include organizing conference sessions at TRB Annual Meetings, planning special conferences, and serving as a forum for discussions.

The Economics of Pricing Joint Subcommittee is a collaborative effort between TRB committees: ABE20 Transportation Economics and ABE25 Congestion Pricing. The subject of pricing traverses the missions of these committees because the policy objectives in pricing include:

• raising revenue
• recovering costs
• influencing behavior
• achieving equity or other social objectives

Eric Gabler serves as chair.
