data gathering
Summary of data gathering
There are more cars and trucks going through the intersection of Spring Street and Route 27 in the morning than the afternoon.
How to determine cars and trucks
Cars are usually used for taking passengers to the destination; in general, they are smaller than trucks. As for trucks, there are larger spaces to carry items, for example, gasoline, foods, and other goods. In addition, school buses are important transportations on campus, but they are counted as neither cars nor trucks.
How to choose days to gather data
I randomly chose days when I had fewer things to deal with, to compare with other busier days. Furthermore, weather situation was considered, because it would affect the results and efficiency. Based on my schedule and the weather, September 19th and 20th were both available.
How to choose five-minute time interval in data
Choosing time is always related to my schedule. On September 19th, I finished my class at 3:25 in Bachelor Hall, which is located right in the intersection of Spring Street and Route 27; the geographic advantage made data gathering easier. On the following day, I did not have classes after 11:15. For the sake of gathering data in required time, I ran to the named place, and accomplish the mission.
Pros and cons of analyzing data
I agree with analyzing data from different sections of 205 classes separately rather than combine into a big set of data. Different people gathered data in different time, so combining all data together is not strong enough to represent the whole traffic situation in this intersection. However, it is too complicated to analyze all data separately; so, we can divided data into several parts, for instance, 9am to 10am on Monday. In this way, we can clearly see every record, and easily analyze the data.
