Objectives

 TRB's newest publications on access management draw on national and state research to respond to the need for a more coordinated approach to transportation and community design that preserves the safe and efficient movement of peoples and goods, provides supporting networks in developed areas, and reinforces desired urban form.

TRB's Access Management Application Guidelines (AMAG) focuses on the applications of access management concepts and provides research-based guidelines on access management treatments and procedures for their applications. The AMAG is a how-to tool for continuing the evolution of access management applications in the United States.
