Amtrak (美国铁路客运公司) was experiencing a downswing in ridership (客运量) along the lines comprising its rail system. Of major concern to Amtrak and its advertising agency DDB Needham, were the long-distance western routes where ridership had been declining significantly.
At one time, trains were the only practical way to cross the vast areas of the west. Trains were fast, very luxurious, and quite convenient compared to other forms of transportation existing at the time. However, times change and the automobile became America’s standard of convenience. Also, air travel had easily established itself as the fastest method of traveling great distances. Therefore, the task for DDB Needham was to encourage consumers to consider other aspects of train travel in order to change their attitudes and increase the likelihood that trains would be considered for travel in the west.
Two portions of the total market were targeted:
1.anxious fliers — those concerned
A. To show the inability of trains to compete with planes with respect to speed and convenience.
B. To stress the influence of the automobile on America's standard of convenience.
C. To emphasize the function of travel agencies in market promotion.
D. To illustrate the important role of persuasive communication in changing consumer attitudes.
