Chapter Content
Transportation Engineering is concerned with the planning, design, operation, and maintenance of safe and efficient transportation systems including roads, railways, airports, and ports.
Detailed Explanation
Transportation Engineering focuses on how to create and maintain the systems that allow people and goods to move from one place to another. This can include designing roads and highways for vehicles, planning railway lines for trains, managing airports for planes, and developing ports for ships. The main goal is to ensure that these systems are both safe for users and operate efficiently to reduce travel time and costs.
