Theories of road design

Theories of road design focus on creating safe, efficient, and comfortable roads by considering factors like traffic flow, safety, environment, and driver behavior. They include principles like functional harmony (matching road type to its use), sight distance (visibility for safety), and ergonomics (driver comfort). Designers analyze how vehicles and pedestrians will use the road over time, aiming to minimize accidents and congestion. These theories combine science and art, balancing technical standards with practical needs to develop roads that serve communities effectively while adapting to changing traffic patterns.
