Transportation engineering is a crucial field that involves the planning, design, operation, and maintenance of transportation networks. These networks are systems of interconnected facilities that allow for the movement of people, goods, and vehicles from one place to another. Transportation engineers work daily to implement and design efficient transportation networks that are safe for the public and protect the environment. There are various types of transportation networks, including highway, rail, air transportation, maritime transportation, intermodal transportation, and urban transportation networks. These networks play a significant role in the economy by facilitating the movement of goods and people and connecting businesses and individuals to markets, opportunities, and services.
