The 1996 Olympic Games in Atlanta provided the impetus for development of NaviGAtor, a system of 1,044 highway-monitoring cameras, 101 changeable message signs, and a central traffic management system used to manage 234 miles of expressways. Designed to improve the flow of traffic and boost safety for motorists, the system is a collaborative effort of GDOT, the Federal Highway Administration, the Metropolitan Atlanta Rapid Transit Authority (MARTA), and the Atlanta Regional Commission. The system provides real-time highway speed and congestion information on the Internet. It also operates a system of transportation information kiosks at such public areas as airports and rest stops. Why did GDOT develop the NaviGAtor program?

A.) to reduce congestion on the roads and to keep drivers safe
B.) to help planes navigate into and out of the state’s major airports
C.) to help collect tolls and other fees to support the department’s budget
D.) to help build new highways and other roadways across the state
