One approach that some have taken is to make public transportation more pleasant to urban residents by imposing rules and regulations for increased comfort and safety. Longer distance public transport, at times, sell food and drink on board, or have a dedicated buffet car and/or dining car. However, some urban transport systems forbid the consumption of food, drink, or even, at times, chewing gum, while utilizing public transport. At times, only specific types of food are forbidden with more risk of making the vehicles dirty. This would include but not be limited to ice creams and fries, and sometimes snack chips. Some systems prohibit carrying open food or beverage containers, even if the food or beverage is not being consumed during the ride. In most Western developed nations, smoking is prohibited in all or some parts of most public transportation systems due to the obvious safety and health issues. Generally smoking is not allowed on buses and trains, while rules concerning stations and waiting platforms differ from various systems compared to other systems.

This rule also applies to sharp instruments that could inflict damage, such as screwdrivers. This is an effort to reduce and eliminate what is becoming popularly known as 'scratchitti', a form of vandalism where messages are carved into a window.
 
Some systems prohibit items of a large size that may take up a lot of space, such as bicycles and other large items. However, more systems in recent years have been permitting passengers to bring bikes. Likewise, many systems prohibit live animals, both large and small, but allow, at times, those that are kept in carrying cases or other closed containers. Additionally, service animals for the blind or disabled are permitted in most cases.
