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.
Levittown is a census-designated place (CDP) and suburban community in Bucks County, Pennsylvania, within the Philadelphia metropolitan area. The population was 53,966 at the 2000 census. It is 40 feet (12 m) above sea level. Though not a municipality, it is commonly recognized as the largest suburb of Philadelphia in Pennsylvania except for Upper Darby Township, (which is the largest suburban township in the three surrounding Pennsylvania counties). Other suburban townships in New Jersey boast larger populations, but these municipalities consist of more than one locality (both Camden and Cherry Hill are urban and suburban communities, respectively, just outside of Philadelphia that have more residents).
