When should the number of intersections on an expressway be minimized?

Minimizing the number of intersections on an expressway serves as a general guideline for designing efficient and safe roadway systems. Expressways are designed to facilitate the fast and efficient movement of traffic, typically focusing on high-speed travel with fewer interruptions.

Having fewer intersections reduces the likelihood of conflicts between vehicles, which can lead to accidents and congestion. This is particularly important on expressways where maintaining higher speeds is crucial for traffic flow and safety. Fewer intersections mean fewer points where vehicles must slow down or stop, which enhances travel time and overall roadway efficiency.

While considerations like safety and peak traffic hours are important, the overarching principle is to maintain a design that allows for smooth traffic movement, adhering to the general guideline of minimizing intersections. This approach ties into broader traffic engineering principles that emphasize streamlined flow and reduced potential for accidents, contributing to more effective expressway design.
