In some sense, travel for sightseeing is a kind of comprehensive recreation. People travel to broaden their fields of vision, increase their knowledge, refresh and relax their bodies. The scenic spots attract tourists not only by beautiful natural and human landscapes, but also by modern entertainment facilities such as gymnasiums, billiard room, song and dunce halls, swimming pools, etc. Concerts, acrobatic performance and theatrical performance are all loved by people. Those recreation parks built in the metropolis are very popular.

Why do people select one transportation mode over another for their business and pleasure/personal trips? Many theories have been put forward on mode selection decision processes. Most theorists, however, consistently identify availability, frequency, cost/price speed/time, and comfort/luxury as the mode decision available. Other factors that have been suggested are safety, convenience, ground services, terminal facilities and locations, status and prestige, and departure and arrival- times. People in different segments of the travel market place varying degrees of value or utility on these criteria. For example, a business departure/arrival times may be all-important to the business traveler, while cost/price may be the pleasure traveler's first criterion.
