What is the design purpose of a motorway?

The design purpose of a motorway is to support fast traffic without crossroads. Motorways are specifically engineered to allow for high-speed travel with minimal interruptions. This means that they are constructed with features like multiple lanes, dedicated exit and entrance ramps, and the absence of traffic signals or intersections. These design elements facilitate the efficient movement of vehicles, especially for long-distance travel, by allowing drivers to maintain higher speeds with fewer disruptions.

Motorways are characterized by a controlled access system, meaning that vehicles can only enter or exit at designated points. This helps to maintain a consistent flow of traffic, which is critical for safety and efficiency while traveling at higher speeds. Furthermore, the roadway is designed to accommodate vehicles that are traveling at high speeds, featuring wider lanes and stronger road surfaces to handle the demands of fast-moving traffic.
