RL9. Access Control

Definition:

The degree that access to abutting land is fully, partially, or not controlled by a public authority. Full access control provides access only at interchanges (interstate, etc.). Partial access control provides no private access. No access control permits private access (driveway, etc.).

Source: Obtained by linking Crash Location (C5) to the Roadway Inventory data.

Element Attributes:
  • Full Access Control
  • Partial access Control
  • No Access Control
Rationale:

Highly correlated with crash rates and, therefore, useful in identifying high hazard locations. Important to guide future highway design and traffic control.
