The Texas Transportation Researcher is a quarterly publication of "the largest university-affiliated transportation research agency in the United States." Located at Texas A&M University, the institution focuses on automobile, rail, air, and all other modes of transportation in an effort to improve system safety and efficiency. The second issue of 2003 includes articles about intelligent software to control stoplight timing and engineering solutions to reduce the occurrence of red light running. Much of the publication's content is specific to Texas transportation issues, but most of these issues are common to many areas in the U.S and hence have wide-reaching implications.
