Traffic Flow Characteristics Traffic engineering applies scientific principles to the planning, design, and operation of transportation systems. The fundamental relationship between traffic flow, speed, and density governs how traffic moves on roadways. Flow is measured in vehicles per hour, speed in miles per hour, and density in vehicles per mile. The relationships between these parameters […]
Pavement Types and Structural Components Pavement design is a critical aspect of highway engineering that determines the long-term performance and service life of road infrastructure. The two primary pavement types are flexible pavements, which use asphalt concrete as the wearing surface, and rigid pavements, which use Portland cement concrete. Each type has distinct structural characteristics,
