Industry History
The Engineers-Traffic & Transportation industry has a long history dating back to the early 19th century when the first steam-powered locomotive was invented. This invention revolutionized the transportation industry and paved the way for the development of modern transportation systems. In the early 20th century, the automobile industry began to take shape, and with it came the need for better roads and highways. This led to the development of the first traffic engineering programs in the United States. In recent years, the industry has seen significant advancements in technology, including the development of intelligent transportation systems, which use sensors and other technologies to improve traffic flow and reduce congestion.

About this classification
This page represents a commercial Extended NAICS industry classification used for business targeting, industry research, data analysis, and company classification. It is not an official U.S. Census Bureau NAICS code. Its parent industry is an official NAICS classification defined by the U.S. Census Bureau. Classifications are reviewed regularly by SICCODE.com's Classification Review Team.
SICCODE.com classifies companies under both Extended NAICS and Extended SIC. A company may appear in both classification systems, so company counts should not be added together without deduplication.
