Highway Engineering involves the design, construction, and maintenance of roads and highways.

Driver behavior is not typically considered in traffic engineering, as it is more related to human factors and psychology.

Traffic signals are used to control the flow of traffic at intersections and other locations.

Roundabouts are not intersections in the traditional sense, as they do not involve stop signs or traffic signals.

Transportation Planning involves the development of long-term strategies and policies for the transportation system.

Ferries are not typically considered public transportation vehicles, as they are used for water transportation rather than land transportation.

Public Transportation Planning involves the design, construction, and operation of public transportation systems.

Roundabouts are not typically considered traffic calming measures, as they are used to improve traffic flow rather than slow it down.

Traffic Engineering involves the management and maintenance of the transportation system.

Airports are not typically considered transportation infrastructure, as they are used for air transportation rather than land transportation.

Highway Engineering involves the design, construction, and maintenance of bridges and tunnels.

Driving is not typically considered a sustainable transportation mode, as it contributes to air pollution and greenhouse gas emissions.

Transportation Planning involves the development of long-term strategies and policies for the transportation system.

Speed limits are not typically considered transportation policies, as they are more related to traffic safety.
