Commuter use of the new subway train is exceeding the transit of the company’s projection.

Argument; 

Commuter use of the new subway train is exceeding the transit of the company’s projection.  However, commuter use of the shuttle buses that transport people to subway stations is below projected volume.  If the transit company expects commuters to ride the shuttle buses to the subway rather than drive there, it must either reduce the shuttle bus fares or increase the price of parking at the subway stations. 

Answer; 

The argument that the bus company needs either cheaper fares for the shuttle bus or more expensive price for parking at the subway stations omits some important concerns that must be addressed in order to assess the validity of this argument. 

Primarily, the author's conclusion does not have enough consideration about punctuality of the bus.  Commuters are usually very careful to be on time because late appearance could lead them to penalty such as deducted payment.  Although the author argues that the shuttle bus should ask smaller fares to customers to reach projected level of transition, no one would take a bus unless it is very punctual.  For example, streets in this city may always suffer from heavy traffic; therefore commuters cannot arrive subway stations on time.  The more assured to be punctual the shuttle buses are to carry commuters to subway trains without delay, the more commuters take a bus.  It is not only a matter of fare or price of parking. 

Another issue ignored by the statement is comfort.  Most commuters want to be relaxed even for a short period of time during their commute.  The shuttle buses might be uncomfortable even just to commute to subway stations from homes.  Who would like to ride an old, dirty, and uncomfortable bus in the morning?  Or drivers driving the shuttles buses might not have a good skill at drive.  Uncomfortable commute consumes energy of workers even in the morning.  Business people would rather save their power with more comfortable transpiration.  

Finally, the author omits location of bus stops and subway stations.  Those who live near a subway station do not take a bus for commute to a station because they could, instead, walk or ride a bicycle.  In fact, many Japanese commuters have a bicycle or walk to a station in order to save transportation fees and even be environment-friendly.  Similarly, those who live far from a bus stop would take another way to get to a station than the shuttle bus, for example, drive or taxi.  Walking a long distance in the morning is hard for some people; therefore, they might take another way to go to a station if the closest bus stop is far enough not to walk. 

In conclusion, the argument in current form is not convincing.  In order to better evaluate the author's claims, more information is needed.  To begin with, timetable of the shuttle bus should be clarified.  Commuters cannot be late at their office.  Whether the shuttle buses run on time is a crucial factor to be chosen as a convenient commute.  Also, comfort of the shuttle buses needs to be considered because everyone wants a comfortable transportation.  Finally, physical availability of the bus is a matter.  Bus stops should be close enough to commuter's home; otherwise, they would drive to a station.  Before any conclusion is made, every factor must be discussed.
