Road Classification in Transportation Planning

Road classification (or class) is a fundamental concept in transportation planning and traffic engineering. It provides a framework for organizing roads according to their function within the transportation network, specifically how they balance mobility (moving traffic efficiently) and access (serving adjacent land uses). Higher-class roads prioritize mobility, moving large volumes of traffic over longer distances […]

Sight Distance Requirements in Road Design

Sight distance is one of the most important considerations in road design. It represents the length of roadway visible to a driver, ensuring there is enough distance to perceive, react, and stop safely when encountering obstacles or conflicts. Inadequate sight distance can lead to unsafe conditions, higher crash risks, and poor traffic flow. This reference
