What is the primary purpose of a roadway in a trafficway?

The primary purpose of a roadway in a trafficway is to serve as the main area for motor vehicle travel. Roadways are specifically designed and constructed to facilitate the movement of vehicles from one location to another, ensuring that traffic can flow safely and efficiently. This includes providing lanes, signage, and surfaces that are suitable for vehicular use, taking into consideration speed limits and traffic regulations.

While accommodating pedestrian traffic, facilitating emergency vehicle access, and providing lateral support for structures are important considerations in roadway design and traffic management, they are secondary to the main function of the roadway itself. The roadway's primary focus is on enabling safe and effective motor vehicle travel, which is crucial for the overall transportation network and mobility within an area.
