? With interviews, locating people and setting up appointments took a considerable amount of time; where and when the interview is conducted can affect the nature of the information that is obtained.
? In doing surveys, the problems we incurred were that survey participants may or may not respond to some of the questions. The time it took to reply to some questions and their own ability to answer the questions also varied from person to person. The resources and costs associated with producing surveys may also be an obstacle.
? In dealing with survey participants it was somewhat
difficult to get people to participate in the survey. A lot of people were
either late for class, or studying for exams and did not have time to answer
the survey. Because of this, the people from whom information was to be
collected must be willing and able to respond to the data collection preferable
to the study at hand.
For our purposes, surveys were advantageous in that they reach a large percentage of the population within a short period of time. They also provide opportunity for additional ideas, input and viewpoints which otherwise may not have been considered. Observations can be used to validate the results of the surveys while having minimal impact on the system. Interviews provide background information and interviewees can respond to and comment on the information received from the surveys and observations.
Because it was difficult to obtain any previous data and the limitation to the length of the study was a factor, a full intensive study of the UW transport system was very difficult to do. The two-week time restriction allocated for data collection purposes was sufficient for our purposes but not for a full intensive study.
