Public transportation usually consists of a network of trains, buses, and other modes of travel that are open to the general public. Using public transportation is usually very relevant in urban settings, where a car may have a difficult time maneuvering in the heavy traffic typical of large cities. Some typical benefits include universal accessibility for most citizens in the city, the absence of car maintenance fees, and being able to lower a community’s pollution. Some of the drawbacks, however, include congested trains and buses, and erratic arrival and departure schedules.
There are many modes of public transportation that can make traveling to distinct parts of the city accessible. A positive is that most modes of transportation are available to anyone, regardless of any physical disabilities that prevents him or her from operating a vehicle. Most city trains and buses are wheelchair accessible. A downside is that the trains and buses can get very congested during peak hours, which can create a claustrophobic environment for some.
Trains are open to everyone who can pay the fare, which is especially helpful for those on a budget, including students and teens using public transportation. Even if the trains can get people to their destinations, most individuals will have to plan their day in accordance with the train's schedule. When a train or bus arrives at a station or makes many stops along the way, the traveler's time can be negatively impacted.
Owning and operating a car has been connected to large, exuberant fees that can quickly add up. Parking fees, insurance, and gas money can quickly eat up a bank account. Another positive of using public transportation is that most trains and buses have comprehensive plans, allowing people to save money on rides. Households that use public transportation on a normal basis will be able to accumulate savings every year.
Leaving the car behind and using public transportation has been known to reduce pollution as well. Public modes of transportation are known to reduce smog-producing pollution and greenhouse gases, as well as preserve ecologically-sensitive land. Smog, smoke, and air pollution also contribute to global warming. Some modern trains use electricity as their main power source, creating very little by-product that can damage the environment.
