Introduction to Highway Engineering and Road Design

Roads and highways form the backbone of modern civilization, connecting communities and enabling economic growth. Understanding how these vital networks are planned, designed, and constructed is the first step toward building safer, more efficient transport systems. This course guides you through the core principles of highway engineering, from initial alignment planning to geometric design and material selection. You will develop a solid foundation in how modern roads are engineered to handle traffic safely and sustainably. In this course, you will: 1. Understand the core principles of highway planning and alignment selection. 2. Master geometric design concepts, including horizontal and vertical curves. 3. Analyze traffic flow characteristics and basic highway capacity parameters. 4. Evaluate pavement materials, soil subgrades, and modern drainage systems. 5. Learn the basics of road safety audits and sustainable infrastructure design. The course begins with essential terminology and the history of transportation networks before moving into practical design calculations, material properties, and modern safety standards. You will progress through written explanations, step-by-step design scenarios, and self-assessment exercises. Designed specifically for beginners, civil engineering students, and aspiring urban planners, this course requires no prior background in transportation engineering.
