Problems and Purpose
Washington D.C. ranks at the top for worst traffic congestion amongst other cities in the United States of America. However, it's not just the city Washington D.C. itself, it is the D.C., Maryland, and Virginia area. This area is known as the Washington Metropolitan area and it is home to an estimated 5,582,170 people. The D.C. area is not at all that big only measuring out to a grand total of 962.9 square miles. This is very problamatic because it yields to the overcrowding of the roads in the nation's capital. Another problem is road system itself.
