Controlled-access highways are fundamentally designed to prohibit direct ingress and egress from adjacent properties, thereby ensuring uninterrupted traffic flow.
Answer: True
The core design principle of controlled-access highways is the prohibition of direct access from adjacent properties to maintain continuous, uninterrupted traffic flow.
Controlled-access highways prevent conflicts with other traffic routes primarily through the implementation of traffic signals at major intersections.
Answer: False
Controlled-access highways prevent conflicts with other traffic routes not through traffic signals, but by employing grade separation (overpasses and underpasses) and eliminating at-grade intersections.
What is the fundamental design principle governing controlled-access highways?
Answer: Regulation of ingress and egress, prohibiting direct property access for uninterrupted traffic flow.
How do fully controlled-access highways achieve unhindered traffic flow?
