Blue-collars are mainly factory workers or in other physically demanding jobs. They are not willing to pay much for transportation, but many of them don't have cars so they prefer public transport if it provides them an easy access to their daily destinations. They mainly move around the city to get to work and back.
Opposed to the Blue-collars, the White-collar workers populate offices, shops and government buildings. They have slightlybetter salaries and don't pay that much attention toticket prices as much, speed and reliability of services is of essence to them. Like Blue-collars, White-collars are work-oriented and don't care much for shopping or leisure.
Business people arethe social group used to portray the upper class: directors, doctors, lawyers and bankers for examplehave lots of money and many of them own cars. They don't care about price, they only need the quickest and most enjoyable way to get to where they are going.
Wherever there is a college, there are students. Students usually don't own cars but prefer walking over pricey public transport unless a cost-effective link between their dormitories, places of study and favored leisure sights is established.
The tourists want to see the city and have savings to spend on their holiday. They are not picky when it comes to price and are only interested in enjoying themselves. Tourists always live in hotels and don't visit workplaces at all.
Pensioners, the salt of the earth, don't spend their hard-earned old-age benefits on cars. They are slow walkers and would prefer to hog seats in public transport vehicles. Pensioners don't go to work, their interests lie in filling forms at government offices, shopping for groceries, meeting peers in churches and strolling in nice parks.
Dropouts are social outcasts, but like all citizens, they still feel the need to get from one place to another. They rarely own cars, don't have workplaces to travel to and have very little money to spend.
