What does improving road signage fall under?

Improving road signage is categorized under traffic engineering programs because it involves the design, installation, and maintenance of signs that communicate important information to drivers and pedestrians. Traffic engineering focuses on the optimization of transportation systems, which includes ensuring that signage is clear, effective, and positioned correctly to enhance safety and traffic flow.

Signage plays a critical role in informing road users about speed limits, directions, hazards, and other crucial details necessary for navigating roadways safely. Therefore, efforts to improve road signage directly relate to enhancing the overall infrastructure and functionality of the transportation system, a key aspect of traffic engineering.
