Transportation Law includes regulations for operators, vehicles and infrastructure; as well as the contract of carriage, regulations and relation between the carrier and passenger in public transport, shipper and cargo owners. Attorneys who practice transportation law represent individuals and businesses in cases involving most aspects of travel and commerce on the ground, in the air, and on the water -- including regulation of private and commercial vehicles, aircraft, and vessels; compliance with transportation safety standards; and oversight of commercial freight shipment activity.
Columbia is a planned community that consists of ten self-contained villages, located in Howard County, Maryland, United States. Columbia is a suburb of Baltimore and, to a lesser degree, Washington, D.C. It began with the idea that a city could enhance its residents' quality of life. Creator and developer James W. Rouse saw the new community in terms of human values, not just in terms of economics and engineering. Opened in 1967, Columbia was designed to not only eliminate the inconveniences of then-current subdivision design, but also eliminate racial, religious, and income segregation. Today, Columbia has a population of about 97,200 and is the most populous census-designated place in Maryland. By the early 2000s, the town had acquired many of the characteristics of other contemporary U.S. suburbs, such as increasingly large private homes on large parcels and "big box" retail stores accessible mostly by automobile. Rouse's ethos remains a strong influence upon the physical and political development of Columbia.
