 Because the area of Rutgers' New Brunswick-Piscataway campus—which is composed of several constituent colleges and professional schools—is sprawled across six municipalities, the individual campuses are connected by an inter-campus bus system.The Rutgers bus system is the second largest bus service in New Jersey, and one of the largest in the country.Services provided by the university include Rutgers Police, Emergency Medical Services, an emergency management office, bus and shuttle service, inter- and intra-campus mail, and occupational and environmental health and safety.
