10 Principles


This animation explains the 10 principles from the TRB Access Management Manual published in 2003. Click on each principle to learn more.

Access management is much more than driveway regulation. It is the systematic control of the location, spacing, design and operation of driveways, median openings, interchanges and street connections. It also encompasses roadway design treatments such as medians and auxiliary lanes, and the appropriate spacing of traffic signals.

With fewer new arterial roadway being built, the need for effective systems management strategies is greater than ever before. By managing roadway access, government agencies can increase public safety, extend the life of major roadways, reduce traffic congestion, support alternative transportation modes, and even improve the appearance and quality of the built environment.

Slide List:
  1. Provide a specialized roadway system
  2. Limit direct access to major roadways
  3. Promote intersection heirarchy
  4. Locate signals to favor through movements
  5. Preserve the functional area of intersections and interchanges
  6. Limit the number of conflict points
  7. Separate conflict areas
  8. Remove turning vehicles from through traffic lanes
  9. Use nontraversable medians to manage left turn movements
  10. Provide a supporting street and circulation system
