portofhouston.com, Houston has ready access to one of the United States’ most dense concentration of consumers (i.e. 144 million consumers within 1,000 miles). With respect to conventional over the road transit, Houston has several major interstates and highways that allow access to major metropolitan areas such as Dallas/Fort Worth and San Antonio.
While passengers and cargo utilize these routes frequently, air travel for passengers between Houston and Dallas is quite common. Recently, a high-speed rail project was initiated to connect the cities of Houston and Dallas with a 100+ mph train.

Conversely, the additional transportation option offered by the high-speed rail will most likely increase overall commerce in Houston and Dallas, yielding increased demand for air traffic to those
destinations.
