Urban transportation is an important part of life in cities and metropolitan areas. It includes a variety of methods, such as ELS (Electric Light System), BUS (BUS Urban System) and CABS (Cab Services). ELS is a form of public transport that uses electric power to move people from one place to another. BUS is a system of buses that run on fixed routes and schedules. CABS are private vehicles that can be hired for a fee to take passengers from one place to another. All three forms of urban transportation provide convenient and efficient ways to get around the city.
