Civil Engineering Professional Engineer Practice Exam

Which civil engineering subfield focuses on transportation systems?

1. Structural engineering

2. Water resources engineering

3. Transportation engineering

4. Environmental engineering

The correct answer is: Transportation engineering

Transportation engineering is the subfield of civil engineering that specifically addresses the design, construction, and maintenance of transportation systems, which include roads, bridges, railways, airports, and mass transit systems. This discipline aims to improve the efficiency, safety, and sustainability of movement for both people and goods. Transportation engineers analyze traffic patterns, develop transportation plans, and ensure the integration of various transportation modes to create a cohesive and effective transportation network. The other subfields do not primarily focus on transportation systems. Structural engineering centers on designing and analyzing structures like buildings and bridges to ensure their stability and longevity. Water resources engineering deals with the management and distribution of water resources, including water supply and drainage systems. Environmental engineering focuses on issues related to environmental protection, such as pollution control and waste management, rather than transportation. Therefore, transportation engineering distinctly fits the criteria of the question, emphasizing its specialized role within civil engineering.
